    The clinical features and neuroradiological and computertomographic findings in 125 patients with cystic intracranial processes, which were neither due to tumour nor of vascular origin, have been analysed. The intrathecal injection of iodinated contrast media is absolutely essential for the differential diagnosis of congenital cysts. CT demonstration using 2 mm. slices and coronal and sagittal reconstruction makes it possible to relate the lesions to surrounding brain structures. Additional anomalies of the brain can be diagnosed and considered when planning treatment. Air studies are no longer necessary, but plain films remain the first diagnostic step. In view of modern micro-surgical techniques, angiography remains of value in order to diagnose vascular anomalies at a pre-operative stage.

    Full Text Available Arachnoid cysts are a rare central nervous system malformation, representing only 1% of all intracranial masses in newborns. Primary (congenital arachnoid cysts are benign accumulation of clear fluid between the dura and the brain substance throughout the cerebrospinal axis in relation to the arachnoid membrane and do not communicate with the subarachnoid space. Secondary (acquired arachnoid cysts result from hemorrhage, trauma, and infection and usually communicate with the subarachnoid space. The common locations of arachnoid cysts are the surface of the brain at the level of main brain fissures, such as sylvian, rolandic and interhemispheric fissures, sella turcica, the anterior cranial fossa, and the middle cranial fossa. Arachnoid cysts may be associated with ventriculomegaly and dysgenesis of corpus callosum. Prenatal ultrasound and magnetic resonance imaging have led to the increased diagnosis of fetal arachnoid cysts. This article provides a thorough review of fetal arachnoid cysts, including prenatal diagnosis, differential diagnosis and associated chromosomal abnormalities, as well as comprehensive illustrations of perinatal imaging findings of fetal arachnoid cysts. Prenatal diagnosis of intracranial hypoechoic lesions should include a differential diagnosis of arachnoid cysts and prompt genetic investigations.

    Two cases of spinal arachnoid cysts are reported. One is extradurally located, the other intradurally. The first is only documented with myelography, the second also by subsequent CT scanning. Some clinical and diagnostic aspects of the lesion are discussed. The aim of this report is to add two new cases to the literature and to emphasize the role of high-resolution CT scanning in the diagnosis of these lesions.

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings.

    The therapeutic management of arachnoid cysts depends largely on its location. Almost 50% of arachnoid cysts are located in the temporal fossa-Sylvian fissure, whereas the other half is distributed in different locations, sometimes exceptional. Under the name of infrequent location arachnoid cysts, a description is presented of those composed of 2 sheets of arachnoid membrane, which are not located in the temporal fossa, and are primary or congenital.

    The preoperative diagnosis of intracranial arachnoid cysts has been simplified, and made more rapid and accurate with computed tomography (CT). Using CT cisternography, detailed anatomic and physiologic information of arachnoid cysts could be obtained. CT features of pathologically proven 21 arachnoid cysts that were examined at Chonnam National University Hospital from June 1983 to May 1987 were analyzed. The results were as follows: 1.Prevalent age group was the 1st decade (8 cases) and male to female ratio was 17:4. 2.Clinical features were related to the location of arachnoid cyst, common symptoms were headache (53.3%), convulsion, mental change and walking disturbance. 3.Location of the arachnoid cyst were in supratentorial region (15 cases) most in middle cranial fossa (12 cases), and infratentorial region (6 cases), common at the retrocerebellar cisternal space (3 cases). 4.Shapes of arachnoid cyst were biconvex with straight inner margin (8 cases), spherical (7 cases), simple biconvex (3 cases) and others (3 cases). 5.Size of the arachnoid cyst, in the greatest dimension, was ranged from 2cm to 9cm and commonly distributed between 3cm to 5cm (14 cases). 6.Of all 14 cases, who did CT cisternography using metrizamide (11 cases) and iopamidol (3 cases), 2 cases had communication with the subarachnoid space.

    Full Text Available Arachnoid cysts are rare, usually benign, space-occupying central nervous system lesion. They are the results of an accumulation of cerebrospinal-like fluid between the cerebral meninges and diagnosed prenatally as a unilocular, simple, echolucent area within the fetal head. They may be primary (congenital (maldevelopment of the meninges or secondary (acquired (result of infection trauma, or hemorrhage. The primary ones typically dont communicate with the subarachnoid space whereas acquired forms usually communicate. In recent years, with the development of radiological techniques, the clinical detectability of arachnoid cysts seems to have increased. We report a case of primary arachnoid cyst that were diagnosed prenatally by using ultrasonography and magnetic resonance imaging . [Cukurova Med J 2016; 41(4.000: 792-795

    1984-06-01

    Anamnesis and treatment of two cases of arachnoid cysts extending into the subarachnoid space are described. No traumatic incident was discovered in the previous history of these two patients. The causal genesis of neurological signs of deficiency in patients with arachnoid and acquired cysts is discussed. However, the cause of the development of a subdural hygroma in arachnoid cysts remains unclarified. CT findings of arachnoid cysts with a hypodense zone between brain surface and the vault of the cranium always require an investigation into the possibility of a spontaneous emptying of the cyst or of a congenital and not only localised extension of the cyst itself.

    Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

    Full Text Available Arachnoid cysts can occur at different intracranial sites, including the cerebellopontine angle (CPA. They often occur in childhood, in the posterior fossa. They may present with symptoms such as dizziness, tinnitus and hearing loss, or they may be asymptomatic. Presentation with sudden deafness is very rare. We report the unusual presentation of a 67-year-old male with CPA arachnoid cyst and the complaint of sudden-onset deafness. In this case, the cystic lesion at the CPA was found by magnetic resonance imaging of the brain. Pathology after retromastoid suboccipital craniotomy confirmed an arachnoid cyst. The treatment of this patient is discussed and the possible causes of CPA arachnoid cyst are briefly reviewed.

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    Background: A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. Case Description: We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extramedullary cyst. Conclusion: Surgery should be considered early in a symptomatic disease course. Longstanding medullary compression may reduce the possibility of neurological recovery as well as secondary complications such as intramedullary cyst formation. PMID:27512608

    Full Text Available Surgical options for suprasellar arachnoid cyst are cystoperitoneal shunt, craniotomy fenestration and endoscopic fenestration. Endoscopic management has been found to be safe and effective. We report our experience with endoscopic management in 12 (male five, female seven; age range 8 months to 42 years patients with suprasellar arachnoid cyst. The endoscopic procedure included lateral ventricle puncture by precoronal burr hole and superior and inferior wall of the cyst was communicated with the lateral ventricle and the interpeduncular cistern respectively. All patients had hydrocephalus. Four pediatric patients had macrocephaly. All adult patients had visual disturbances. One adult patient presented with psychomotor disturbance along with features of raised intracranial pressure. All cases improved following endoscopic treatment. There were no complications or death. One patient required VP shunt. Postoperative MRI showed significant reduction in cyst volume in 11 patients. Follow-up ranged from 6 months to 6 and a half years. Our study suggests that endoscopic technique is a safe and effective alternative treatment for suprasellar arachnoid cyst. It prevents complications such as subdural effusion and intracranial hematoma, which are not uncommon with craniotomy fenestration.

    Full Text Available Introduction: The purpose of this study is to evaluate the distribution, clinical features, and treatment modalities of arachnoid cyst in our department. The study was carried out between April 1, 1996 and October 1, 2006 at the neurosurgery department, Ghaem hospital, Mashhad university of medical sciences. Material and Methods: Twenty patients with arachnoid cyst underwent surgery between April 1, 1996 until October 1, 2006, consisting of 12 males and 8 females ranging in age 5 to 68 years (mean age 32.4 years. Twelve patients underwent surgery and one patient underwent endoscopic fenestration, and cystoperitoneal shunting (medium pressure was performed in 7 patients. All patients were followed for minimum of 6 months after surgery. Results: During the study period, 20 patients were investigated. The cysts had strong predilection for the middle cranial fossa in 12 patients (60%, suprasellar region in 1 patient (5%, the cerebral convexity in 1 patient (5%, posterior cranial fossa in 2 patients (10%, cerebellopontine angle in 3 patients (15%, quadrigeminal cisterns in 1 patient (5%. All of 20 cysts had clearly unilateral distribution, 12 (60% were located on the left side and 8 (40% on the right side. The most common symptoms on presentation were epileptic seizures (46%, increased intracranial pressure (34%, visual impairment (5%, headache (10%, cerebellar sign (5%. Conclusion: Arachnoid cysts have a strong predilection for the middle cranial fossa that may be explained by a meningeal maldevelopment theory. We also conclude that the major indication for surgery in patients with arachnoid cyst is the presence of intractable seizures, increased intracranial pressure, and compression of neuronal tissues. Headache only is not a surgical indication.

    Intradiploic arachnoid cysts have scarcely been reported in the literature, most reported cases being secondary to trauma. Non traumatic arachnoid cysts are quite rare and have been reported mostly in adults. Here, we report the case of a 16-year-old male presenting with a slowly growing mass in the occipital region and intermittent headaches. On the basis of the findings of X-rays, computed tomography scans, and magnetic resonance imaging scans of the head, the mass was diagnosed as a giant intradiploic arachnoid cyst.

    Full Text Available Presence of an arachnoid cyst at craniospinal junction is not very common. This is a very rare anatomic site, with only seven other cases reported in the literature. We report a case of large intradural craniospinal arachnoid cyst presenting with obstructive hydrocephalus and cranial nerve palsy. A 39-year-old male presented with 8-month history of neck pain, headache, vomiting, visual disturbances, diminished taste sensation, and numbness of face. He had bilateral papilledema on ophthalmoscopy. Magnetic resonance imaging (MRI revealed a posterior fossa arachnoid cyst extending down to the lower border of C5 vertebra. Posterior decompression was done through C5 laminectomy. He made a full recovery and was asymptomatic at 6-month follow-up examination. The clinical features, diagnosis, and management of these rare craniospinal arachnoid cysts are discussed.

    An intradural arachnoid cyst is a relatively rare condition, occurring within the spinal subarachnoid space. We present the even-more rare case of an intradural arachnoid cyst associated with syringomyelia at the same spinal level. The patient was a 66-year-old man who presented with bilateral leg numbness and gait disturbance. Magnetic resonance imaging (MRI) revealed an intradural arachnoid cyst located dorsal to, and compressing, the thoracic spinal cord at the level of the 7th thoracic vertebra (Th 7). In addition, syringomyelia existed at the level of Th 8, slightly caudal to the intradural arachnoid cyst. We dissected the cyst but did not perform any surgical procedures for the syringomyelia. Post-operative MRI showed that the cyst had disappeared and the syringomyelia had spontaneously shrunk. The patient was discharged with improvement in his numbness and gait disturbance. There are a few case reports of intradural arachnoid cysts associated with syringomyelia, but recent evidence suggests that its occurrence is more common than previously thought. A combination of these two diseases is thought to be caused by blockage of cerebrospinal fluid (CSF) flow, which is also thought to cause adhesive arachnoiditis. For this reason, resection of the arachnoid cyst could improve the CSF flow and contribute to the shrinkage of syringomyelia. Furthermore, early treatment may correlate with improvement in radiological findings and neurological symptoms.

    Spinal arachnoid cysts are an infrequently reported cause of abdominal pain in children. In this report, we describe the unusual case of an extradural arachnoid cyst presenting as recurrent abdominal pain in a pediatric patient without any signs of cord or nerve root compression. A 14-year-old girl with recurrent abdominal pain as the only symptom of a spinal extradural arachnoid cyst is reported. The patient was incidentally diagnosed with an intraspinal mass on abdominal computed tomography (CT) during the course of investigating her abdominal pain. Magnetic resonance (MR) imaging confirmed the diagnosis of a T11-L2 extradural arachnoid cyst. After resection of the T11-L2 arachnoid cyst, the patient's abdominal pain resolved. To our knowledge, this is the first report describing abdominal pain as the sole presenting feature of a spinal arachnoid cyst in the pediatric population. This case illustrates that abdominal pain may be the first and only presentation of spinal arachnoid cysts in children. Spinal pathology should be considered in the differential diagnosis of unexplained abdominal pain, even when there are no other symptoms of spinal disease.

    Clarification of the subjective complaints caused by meningeal malformations represented by an arachnoidal cyst in the sacral region was achieved for the first time by analysing an arachnoidal cyst which had been determined by myelography, computed tomography, biopsy and histological examination. Principles of mechanics and dynamics play an important part. The pattern of complaints is mainly due to the communication between the cyst and the CSF space, as well as a valve mechanism with filling of the cyst. Surgical reduction or removal of the cyst, and elimination of the connection with the CSF, produced freedom from complaints.

    The prevalence of arachnoid cysts in children is 1-3%. They are more frequent in boys. They can be located intracranially or in the spine. Intracranial cysts are classified as supratentorial, infratentorial, and supra-infratentorial (tentorial notch). Supratentorial are divided into middle cranial fossa, convexity, inter-hemisferic, sellar region, and intraventricular. Infratentorial are classified into supracerebellar, infracerebellar, hemispheric, clivus, and cerebellopontine angle. Finally spinal arachnoid cysts are classified taking into account whether they are extra- or intradural, and nerve root involvement. Copyright © 2015 Sociedad Española de Neurocirugía.

    We recently encountered two large intrasellar arachnoid cysts extending to the suprasellar region. The intensity of the cyst contents was identical to that of the cerebrospinal fluid on both T1- and T2-weighted MRI. On contrast-enhanced MRI, the pituitary gland was compressed posteroinferiorly and flattened in the sella turcica. In this report of rare intrasellar arachnoid cysts the discussion is focused on dislocation of the pituitary gland. (orig.)

    Full Text Available Arachnoid cysts are developmental anomalies which are usually asymptomatic. Intracystic hemorrhage after trauma is a well known complication; however, spontaneous intracystic hemorrhage is rare. This report presents two rare cases of arachnoid cyst complicated by spontaneous intracystic hemorrhage. The first patient was admitted following transient loss of consciousness and speech disturbance, and a subacute subdural hematoma at the left temporal region was diagnosed. The second patient presented with severe headache of four days duration and a subdural hematoma at the left temporoparietal region was diagnosed. In both the patients, both on radiological examination and during surgical intervention, hematomas were found to be intracystic.

A case of 14 year old female is being reported, who presented with hydrocephalus caused by a large midline retrocerebellar infravermal arachnoid cyst leading to obstruction of the outlet foramina of the fourth ventricle. There was associated syringomyelia. The pathogenesis of syringomyelia is discussed. The need to evaluate cervical spinal cord by taking T1 weighted sagittal sections in all the patients of large posterior fossa mass lesions causing obstruction to the outlet foramina of the fourth ventricle has been stressed, in order to detect associated syringomyelia.

    Full Text Available Abstract Background The aetiology of a psychotic disturbance can be due to a functional or organic condition. Organic aetiologies are diverse and encompass organ failures, infections, nutritional deficiencies and space-occupying lesions. Arachnoid cysts are rare, benign space-occupying lesions formed by an arachnoid membrane containing cerebrospinal fluid (CSF. In most cases they are diagnosed by accident. Until recently, the coexistence of arachnoid cysts with psychiatric disturbances had not been closely covered in the literature. However, the appearance of some references that focus on a possible link between arachnoid cysts and psychotic symptoms has increased the interest in this subject and raised questions about the etiopathogeny and the therapeutic approach involved. Clinical presentation We present the clinical report of a 21-year-old man, characterised by the insidious development of psychotic symptoms of varying intensity, delusional ideas with hypochondriac content, complex auditory/verbal hallucinations in the second and third persons, and aggressive behaviour. The neuroimaging studies revealed a voluminous arachnoid cyst at the level of the left sylvian fissure, with a marked mass effect on the left temporal and frontal lobes and the left lateral ventricle, as well as evidence of hypoplasia of the left temporal lobe. Despite the symptoms and the size of the cyst, the neurosurgical department opted against surgical intervention. The patient began antipsychotic therapy and was discharged having shown improvement (behavioural component, but without a complete remission of the psychotic symptoms. Conclusion It is difficult to be absolutely certain whether the lesion had influence on the patient's psychiatric symptoms or not. However, given the anatomical and neuropsychological changes, one cannot exclude the possibility that the lesion played a significant role in this psychiatric presentation. This raises substantial problems when it

    With a high likelihood of clinical improvement and low rates of complications, minimally invasive neuroendoscopic surgery is becoming the treatment of choice for symptomatic or growing arachnoid cysts. In neuroendoscopic surgery, visualization of anatomical landmarks is essential in achieving successful fenestration without complications. Because of the restricted visual field in neuroendoscopic surgery, preoperative anatomical assessment is very helpful. Magnetic resonance cisternography (MRC) with high spatial resolution and contrast, using for example 3-D Fourier transformation constructive interference in steady state (CISS) or fast imaging employing steady-state acquisition (FIESTA) sequences, is able to detect the arachnoid cyst wall and neighboring anatomical structures as the anatomical landmarks. We retrospectively reviewed T2-weighted (T2-W) fast spin-echo images, and the MRC and intraoperative findings. Axial and coronal T2-W images (6 and 3 mm thickness, respectively) and axial and coronal 0.8 mm thick MRC images with CISS or FIESTA were obtained from four patients with arachnoid cysts treated by neuroendoscopic surgery. Intraoperative findings were reviewed on videotape recorded during the procedures. At the brain surface, the arachnoid cyst wall could be detected clearly in any of the four patients on MRC images, and was only partly seen in the fourth patient T2-W images. Adjacent important anatomical structures including vessels and cranial nerves, and an enough space for cystocisternostomy were identified on MRC images, and the findings were consistent with the findings during neuroendoscopic surgery. Preoperative identification of the arachnoid cyst wall and surrounding anatomical structures by MRC may help avoid complications and allow safer neuroendoscopic surgery. (orig.)

    We report the case of a 43-year-old man with a middle cranial fossa arachnoid cyst who presented post trauma with neurological symptoms. The initial CT scan of the brain did not detect acute changes in the arachnoid cyst but subsequent imaging revealed abnormalities which progressed over time. Arachnoid cysts are usually a benign and incidental finding. Rare complications such as intracystic haemorrhage and subdural haemorrhage can occur. It is important to be aware of these complications so that patients with arachnoid cysts are appropriately investigated when presenting with neurological symptoms.

    Ecchordosis physaliphora (EP) is a rare, benign tumor derived from the notochordal remnants. Usually slow growing with an indolent course, most cases are incidental findings on autopsy. Limited data exists on symptomatic patients with EP. Diagnosis mainly relies on correlating histopathologic findings confirming the notochordal elements with MRI. We herein present a middle aged woman with symptomatic EP in the pre-pontine cistern that mimicked an arachnoid cyst on preoperative scans. Additionally, we emphasize the pathological and radiological characteristics of EP that could aid in prompt diagnosis of the lesion with emphasis on considering EP as a differential for mass lesions localized in the pre-pontine cistern.

    Full Text Available Spinal epidural arachnoid cyst (EAC is a rare, usually asymptomatic condition of unknown origin, which typically involves the lower thoracic spine. We report a case of posttraumatic symptomatic EAC with lumbar disc herniation. A 22-year-old man experienced back pain and sciatica after a traffic accident. Neurological examination revealed a right L5 radiculopathy. Magnetic resonance imaging demonstrated a cystic lesion at the L3 to L5 level and an L4-5 disc herniation; computed tomography myelography showed that the right L5 root was sandwiched between the cyst and the herniation. A dural defect was identified during surgery. The cyst was excised completely and the defect was repaired. A herniation was excised beside the dural sac. Histology showed that the cyst wall consisted of collagen and meningothelial cells. Postoperatively the symptoms resolved. Lumbar spinal EACs are rare; such cysts may arise from a congenital dural crack and grow gradually. The 6 cases of symptomatic lumbar EAC reported in the literature were not associated with disc herniation or trauma. In this case, the comorbid disc herniation was involved in symptom progression. Although many EACs are asymptomatic, comorbid spinal disorders such as disc herniation or trauma can result in symptom progression.

    Syringomyelia is a not infrequent pathology that develops related to changes in cerebrospinal fluid dynamics due to many etiological factors. The development of syringomyelia through a spinal arachnoid cyst is quite rare and has been defined in only 31 cases in the literature. A case due to thoracic epidural lipomatosis has also been reported. There have been no previous reports of thoracic region epidural lipomatosis with underlying arachnoid cyst and syringomyelia as in our case. We present a 27-year-old patient who developed thoracic arachnoid cyst and underlying syringomyelia because of the pressure of the thoracic epidural fat tissue and also evaluate the characteristics of patients with syringomyelia by virtue of an arachnoid cyst previously reported in the literature.

    We present a 2.5-year-old child suffering from acute hydrocephalus. First, the child was diagnosed with aseptic viral meningitis. The PCR of the cerebrospinal fluid (CSF) was positive for enterovirus. Subsequently, MRI revealed that the hydrocephalus was caused by a cyst in the third ventricle. During ventriculoscopy, the cyst had all aspects of an arachnoid cyst. An endoscopic fenestration and partial removal of the cyst was performed, combined with a ventriculocisternostomy. The coincidental finding of viral meningitis and a third ventricle arachnoid cyst in a patient with acute hydrocephalus has, to our knowledge, not been described in literature before. If there is a relation between the enteroviral meningitis, the arachnoid cyst (possibly causing a pre-existing subclinical hydrocephalus) and the rapidly evolving neurological deterioration, remains speculative. Proposed mechanisms, by which the viral meningitis could accelerate the disease process, are slight brain swelling or increased CSF production. This rare combination of diagnoses could also be coincidental.

    A less invasive transsphenoidal approach with a keyhole dural opening for intrasellar arachnoid cysts is described. This approach was used to address seven sellar cystic lesions with suprasellar extension; they were six intrasellar arachnoid cysts (IACs) and one Rathke's cleft cyst (RCC). In all cases, preoperative MRI revealed cerebrospinal fluid (CSF) intensity on both T1- and T2-weighted images. On preoperative contrast-enhanced MRI, five of the six IACs manifested posterior displacement of the flattened pituitary gland toward the dorsum sellae; one of the six IACs and the RCC exhibited a flattened pituitary gland on the anterior surface of the cyst. Wide cyst cisternostomy through a keyhole dural opening was carried out safely using a microscope with the support of a thin angled endoscope (30° and/or 70°, diameter 2.7 mm). As we aimed to avoid iatrogenic injury of the pituitary function, we found it difficult to obtain a sufficiently wide and precise opening of the cyst wall when the pituitary gland was located on the anterior surface of the cyst wall. Our approach facilitates safe cyst cisternostomy as wide as that obtainable by transcranial manipulation. In addition, CSF leakage is prevented by dural plasty using the fascia lata and stitching with 6-0 monofilament sutures. This technique can be adapted to address various sellar cystic lesions. However, as the posterior or anterior displacement of the normal pituitary gland in the presence of IACs or RCCs, respectively, affects the width of the cyst opening, our technique is more suitable for IACs than RCCs.

    Posterior fossa arachnoid cysts (PFAC) are mostly considered as benign lesions of the cerebellum. Although many studies have shown the major role of the cerebellum in modulating movement, language, cognition, and social interaction, there are few studies on the cognitive impact and surgical decompression of PFAC. We present the cases of two brothers successively diagnosed with PFAC and neuropsychological delay. After multidisciplinary discussion with the boys' parents, it was decided to drain these lesions. Clinical signs, cerebral images, and neuropsychological status were assessed on admission and then 1 and 3 years after surgery. At presentation, both children had mild cerebellar signs, associated with cognitive and visual-motor impairments and academic regression. CT scans revealed retrovermian cysts, which were shunted. Post-operatively, both brothers demonstrated improved visual-motor skills and behavior. At follow-up, we observed disappearance of dysarthria and academic delay and significant improvement in cognition especially at the intelligence scale and in language. Fine motor skills had improved but remained slower than the average and writing skills appeared limited. Except for PFAC which impair cerebrospinal fluid circulation or which are responsible for a significant mass effect, most PFAC are usually considered as "asymptomatic" and do not require surgical treatment. The two cases reported herein suggest that these lesions might be responsible for some associated but potentially reversible neuropsychological impairment. In the future, clinical assessment should include neuropsychological evaluation to help inform decision for surgical decompression in these children with PFAC.

    Arachnoid cysts (AC) are filled with liquid very similar to cerebrospinal fluid (CSF). The mechanisms of fluid accumulation have remained unknown; previous studies have however indicated both fluid secretion and a one-way valve as a mechanism. If the filling was caused by fluid secretion, mechanisms similar to those underlying CSF production would be anticipated. We have investigated the expression levels of all genes known to be involved in mammalian CSF production in surgically removed AC. Based on mRNA microarray analysis of AC and normal arachnoid tissue, we extracted the RNA expression profiles of all genes known to code for proteins involved in CSF production. A selection of genes was further investigated with quantitative real-time polymerase chain reaction (qRT-PCR). For selected CSF production proteins, electron microscopic immunogold techniques (EM) and Western blots were performed. Seven genes were expressed in both cysts and controls. The gene encoding the Na(+)-K(+)-2Cl(-) cotransporter NKCC1 was significantly up-regulated in AC. Gene expression data were supported by Western blot. EM demonstrated NKCC1 expressed at the plasma membranes of the cyst-lining cells. This result points at secretion as the main mechanism of cyst filling, and NKCC1 as the key candidate of fluid transport. Based on these findings, we hypothesize that selective NKCC1 inhibitors could be used in preventing expansion of temporal AC.

Feline intracranial arachnoid cysts are seldom reported, with only three cases in the veterinary literature. A 1-year-old male neutered European cat with a 24 h history of seizures was presented to the small animal neurology department at Vetagro Sup, Lyon. Magnetic resonance imaging (MRI revealed a large intracranial arachnoid cyst ventral to the brain in the left temporal area. Cystoperitoneal shunt placement resulted in complete resolution of the cyst without recurrence (follow-up MRIs 3 weeks and 21 months after surgery. Anticonvulsant treatment (phenobarbital 2.5 mg/kg q12h was initiated at presentation and gradually stopped after 17 months. Seizures recurred 4 months after ending treatment, and seizure therapy was therefore restarted at the initial dose. We report a case of an intracranial arachnoid cyst in an unusual location not previously described. A cystoperitoneal shunt resolved the cyst without complications. Maintenance anticonvulsant treatment was required to control symptomatic epilepsy.

    Full Text Available The treatment options for symptomatic arachnoid cysts are shunting, open craniotomy, and endoscopic fenestration. Endoscopic fenestration of large arachnoid cyst is safe and effective. Postoperative subdural hematoma and intraparenchymal hemorrhage can be avoided by endoscopic fenestration. This technique has the additional advantage of identifying and treating ventricular abnormalities, such as foramen of Monro stenosis and cerebral aqueduct occlusion. This report describes endoscopic dual fenestration in a child with large multicompartmental intraventricular arachnoid cyst extending from foramen magnum to foramen of Monro. The child presented with difficulty to hold the neck in upright position, irritability, vomiting, and large head. Follow-up postoperative magnetic resonance imaging at 3 months showed a significant reduction in size of the cyst. Clinically, the patient showed a gradual improvement at 10 months follow-up. Probably this is the first report of this nature.

    It is very rare that a foramen magnum arachnoid cyst induces compression of the spinal cord and syringomyelia, and currently there are few treatment experiences available. Here we reported the case of a 43-year-old male patient who admitted to the hospital due to weakness and numbness of all 4 limbs, with difficulty in urination and bowel movement. MRI revealed a foramen magnum arachnoid cyst with associated syringomyelia. Posterior fossa decompression and arachnoid cyst excision were performed. Decompression was fully undertaken during surgery; however, only the posterior wall of the arachnoid cyst was excised, because it was almost impossible to remove the whole arachnoid cyst due to toughness of the cyst and tight adhesion to the spinal cord. Three months after the surgery, MRI showed a reduction in the size of the arachnoid cyst but syrinx still remained. Despite this, the symptoms of the patient were obviously improved compared to before surgery. Thus, for the treatment of foramen magnum arachnoid cyst with compression of the spinal cord and syringomyelia, if the arachnoid cyst could not be completely excised, excision should be performed as much as possible with complete decompression of the posterior fossa, which could result in a satisfying outcome.

    Arachnoid cysts most frequently occur in the middle cranial fossa and when they are symptomatic, patients present with central nervous symptoms. Nevertheless, a large proportion of arachnoid cysts are incidentally diagnosed during neuroimaging in cases with nonspecific symptoms. The cases of two males with middle cranial fossa arachnoid cysts with nonspecific inner ear symptoms were retrospectively reviewed. The first patient presented with mild headache, nausea, vertigo, unsteadiness, and tinnitus on the left ear while the second patient's main complaint was left sided tinnitus. Both patients (initially managed for peripheral disorders) underwent a thorough clinical and electrophysiological evaluation. Because of the patients' persistent clinical symptoms, and indications of CNS disorder in the first case, neuroimaging by brain MRI was performed revealing a middle cranial fossa arachnoid cyst in both patients. Occasionally, patients with arachnoid cysts may present with mild, atypical or intermittent and irrelevant symptoms which can mislead diagnosis. Otorhinolaryngologists should be aware of the fact that atypical, recurrent or intermittent symptoms may masquerade a CNS disorder. Hippokratia 2014; 18 (2):168-171.

    Arachnoid cysts are benign space-occupying lesions formed by an arachnoid membrane containing cerebrospinal fluid. Controversy continues regarding the optimal surgical management. There is ongoing debate regarding whether to fenestrate or to perform shunting of the cyst. We present a single-institution experience on surgical treatment of arachnoid cyst using cistoperitoneal shunt. This serie includes 49 children (31 males/18 females) with a diagnosis of intracranial arachnoid cyst and average age of 4-9 years (range 1-16). The predominant symptom was intracranial hypertension in 26 patients (53%). There were 12 complications in 10 patients. We conclude that arachnoid cyst are located predominantly in the temporal fossa. Cisto-peritoneal shunt is a good option in the younger children and have improved clinical symptoms.

    Background. Arachnoid cysts are intra-arachnoidal cerebrospinal fluid collections that are usually asymptomatic, however, they may become acutely symptomatic due to enlargement of the cyst or the presence of hemorrhage. Materials and methods. We report a case of a child presenting with a 3-week history of headaches, nausea, and vision problems. There was no history of trauma. MRI clearly demonstrated a left middle cranial fossa arachnoid cyst with associated subacute intracystic and subdural hematoma that was causing mass effect and required surgery. Results. This lesion was isodense to the brain on CT. Conclusion. We focus on the importance of MR imaging in the differentiation of these subacute/early chronic hemorrhagic collections that may be overlooked with CT. (orig.)

    Cine-magnetic resonance (MR) imaging examinations were performed in 10 patients with middle cranial fossa arachnoid cysts to evaluate communication between the cysts and the normal cerebrospinal fluid (CSF) space. Eight of 10 patients were evaluated by time of flight cine-MR imaging, and two by phase contrast cine-MR imaging. Two patients underwent membranectomy of the cysts, and were evaluated both pre- and postoperatively. Computed tomography cisternography was used to confirm communication between the cysts and the surrounding cisterns. Pulsatile fluid motion within the cysts was present in all patients. However, marked fluid motion and jet flow between the cysts and the surrounding cisterns were only observed in communicating cysts. In the two patients who underwent membranectomy, postoperative examination found greater fluid motion and jet flow not previously present. Cine-MR imaging demonstration of marked pulsatile fluid motion accompanied by jet flow suggests that a cyst communicates with the normal CSF space.

    Objectives To reveal the relationship of brain motion and cerebrospinal fluid (CSF) flow by phase-contrast cine MRI, and to evaluate this technique in differentiating between arachnoid cysts and subarachnoid space enlargement. Methods Using a phase-contrast cine MRI pulse sequence, we measured brain motion and CSF flow during the cardiac cycle in 10 healthy volunteers and 10 patients with MRI-suspected arachnoid cyst or subarachnoid space enlargement. CSF stroke volume curve was illustrated according to flow quantification, and time-signal intensity curve was traced. The two curves were compared. Results This study showed that brain motion was due to the volume difference between arterial and venous blood flow during a cardiac cycle, and thus drives CSF pulsation. Arachnoid cysts and subarachnoid space enlargement carried different curve patterns, demonstrating that phase-contrast MRI and flow quantification can be a useful and reliable technique for non-invasive evaluation of brain motion and CSF flow. Conclusion Arachnoid cysts can be successfully differentiated using phase-contrast cine MRI from subarachnoid space enlargement.

    Intracranial endoscopy has emerged as an innovative surgical tool for various intracranial procedures, but its use remains limited to neurosurgeons trained in this minimally invasive technique. Complex, skull base arachnoid cysts represent one entity that is challenging to treat because of adjacent critical neurovascular structures; however, the advent of intracranial endoscopic techniques has revolutionized treatment. Arachnoid cysts located in the suprasellar-prepontine skull base region can cause obstructive hydrocephalus or symptomatic mass effect and require urgent decompression. These patients may present with nonfocal symptoms that can quickly lead to a life-threatening condition if not accurately diagnosed and treated. The authors present a summary of the world literature of suprasellar-prepontine arachnoid cysts (SPACs) to ascertain clinical presentations and provide class III evidentiary treatment guidelines for this uniquely challenging type of arachnoid cyst. Urgent endoscopic third ventriculostomy results in normalization of intracranial pressure, return of normal CSF flow, and relief of symptoms.

    A 32-year-old pregnant woman developed a progressive right sixth cranial nerve palsy as an isolated finding. Brain MRI disclosed a discrete lobulated lesion centered in the right Meckel's cave with intermediate signal on T1, high signal on T2, and diffusion characteristics similar to those of cerebrospinal fluid on apparent diffusion coefficient mapping. The initial radiologic diagnosis was schwannoma or meningioma. No intervention occurred. Shortly after cesarean delivery, the abduction deficit began to lessen spontaneously. One month later, the abduction deficit had further improved; 7 months later it had completely resolved. Repeat MRI after delivery failed to disclose the lesion, which was now interpreted as consistent with an arachnoid cyst arising within Meckel's cave. Twenty-one similar cases of Meckel's cave arachnoid cyst or meningocele have been reported, 7 found incidentally and 14 causing symptoms, 2 of which produced ipsilateral sixth cranial nerve palsies. All previously reported symptomatic patients were treated surgically. This is the first report of an arachnoid cyst arising from Meckel's cave in pregnancy and having spontaneous resolution.

    The cavum velum interpositum (CVI) is a thin, triangular-shaped cerebrospinal fluid (CSF)-filled space between the lateral ventricles that lies below the fornices and above the third ventricle. It is a normal variant seen in premature and newborn infants and usually disappears with brain maturation. CVI is rarely seen in adults as a persistent primitive structure. Although moderate cystic dilatation of the CVI may sometimes be observed, a true large cyst is extremely rare with only a handful of reported cases, mostly in children and adolescents. We describe the case of CVI arachnoid cyst diagnosed on imaging in a septuagenarian with the complaint of occasional headaches.

    The purpose of this study was to demonstrate the usefulness of digital subtraction cystography to identify communicating holes between a spinal extradural arachnoid cyst (SEAC) and the subarachnoid space prior to cyst removal and hole closure. Six patients with SEAC were enrolled in this retrospective study. Digital subtraction cystography and subsequent CT myelography were performed for every patient. The presence and location of the communicating holes on cystography were documented. We evaluated the MRI characteristics of the cysts, including location, size, and associated spinal cord compression; furthermore, we reviewed cystographic images, CT myelograms, procedural reports, and medical records for analysis. If surgery was performed after cystography, intraoperative findings were compared with preoperative cystography. The location of the communicating hole between the arachnoid cyst and the subarachnoid space was identified by digital subtraction cystography in all cases (n = 6). Surgical resection of SEAC was performed in 4 patients, and intraoperative location of the communicating hole exactly corresponded to the preoperative identification. Fluoroscopic-guided cystography for SEAC accurately demonstrates the presence and location of dural defects. Preoperative digital subtraction cystography is useful for detection of a communicating hole between a cyst and the subarachnoid space.

    Full Text Available  Secondary intradural arachnoid cysts involving the spine are uncommon and can be due to trauma, surgery, lumbar puncture, intrathecal injection and arachnoiditis (TB meningitis, chemical meningitis. Caudal dislocation of the cerebellar tonsils may be associated with known clinical conditions such as intracranial mass lesions or Chiari I and II malformations. It may also be acquired after repeated lumbar punctures or lumboperitoneostomy and traumatic CSF leaks. In rare cases it is reported after supratentorial shunting. "nHere a 16 year old boy is presented with progressive spastic paraparesis 18months after a ventriculoperitoneal shunt. Brain MRI revealed acquired post surgical cerebellar herniation and the spinal MRI showed a large intradural arachnoid cyst. TB laboratory tests were negative. Laminectomy, cyst drainage and suboccipsital craniectomy were performed. Despite the surgery, the disease progression continued to severe paraparesis.

    The existence of a focal brain lesion that might be the crucial cause for the development of diverse psychiatric phenomena and certain characteristics of personality is often a controversial issue. The patient was a 29-year-old male when he killed his father with a single knock with the blunt side of an axe. Subsequently to the act, the patient developed a 10-month-long catatonic stupor during which he experienced intensive fear, delusions, and affective symptoms. He was an emotionally blunted person with no medical record and without prior history of aggressive behavior. Magnetic resonance image revealed a large, right-sided arachnoid cyst that was associated with right temporal and frontal lobe hypoplasia and bilateral changes of perfusion in peri-insular regions. The treatment with clozapine and diazepam showed to be therapeutic. This could be the second case of homicide committed by a person with arachnoid cyst and without past history of aggression, and the second description of an adult patient with cyst who developed catatonic stupor. This is the first description of long-lasting organic catatonic stupor treated with clozapine and diazepam. Relevant literature is reviewed and some controversial issues are discussed.

    OBJECTIVE Arachnoid cysts (ACs) are congenital lesions bordered by an arachnoid membrane. Researchers have postulated that individuals with an AC demonstrate a higher rate of structural brain injury after trauma. Given the potential neurological consequences of a structural brain injury requiring neurosurgical intervention, the authors sought to perform a systematic review of sport-related structural-brain injury associated with ACs with a corresponding quantitative analysis. METHODS Titles and abstracts were searched systematically across the following databases: PubMed, Embase, CINAHL, and PsycINFO. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed case reports, case series, or observational studies that reported a structural brain injury due to a sport or recreational activity (hereafter referred to as sport-related) with an associated AC were included. Patients were excluded if they did not have an AC, suffered a concussion without structural brain injury, or sustained the injury during a non-sport-related activity (e.g., fall, motor vehicle collision). Descriptive statistical analysis and time to presentation data were summarized. Univariate logistic regression models to assess predictors of neurological deficit, open craniotomy, and cystoperitoneal shunt were completed. RESULTS After an initial search of 994 original articles, 52 studies were found that reported 65 cases of sport-related structural brain injury associated with an AC. The median age at presentation was 16 years (range 4-75 years). Headache was the most common presenting symptom (98%), followed by nausea and vomiting in 49%. Thirteen patients (21%) presented with a neurological deficit, most commonly hemiparesis. Open craniotomy was the most common form of treatment (49%). Bur holes and cyst fenestration were performed in 29 (45%) and 31 (48%) patients, respectively. Seven patients (11%) received

    Horner syndrome (HS) results from the interruption of sympathic pathway, and the patients have a group of signs including miosis, ptosis, enophthalmos, and anhydrosis. While HS is mainly caused by cervical sympathetic nerve injury such as sympathetic chain tumor, we report here a HS case caused by a thoracolumbar arachnoid cyst. Imageological examination showed the cyst existed in spinal canal from the T11 to L3 level, which was further confirmed by operation. The tumor attacked the lateral margin of intervertebral foramen at certain stages. In MRI scan, no abnormality was found in the patient's crania, cervical vertebra, thoracic vertebra, or the other parts. After removal of the cyst with operation, the patient's HS symptoms and weakness of lower limbs were relieved apparently. Although the sympathetic center origins from the cornu laterale medullae spinalis of T1 to L3, there are many reports about HS caused by lumbar anesthesia and epidural anesthesia according to our literature review, and there is no report about HS results from intraspinal space-occupying lesion below T11 level. Our finding suggests that when the sympathetic center below the level of T11 emits nerve to dominate abdominal viscera, it can also control the sweat glands from face to feet, including pupils and eyelids. When physicians encounter patients with HS and one side of the body and abdominal viscera sympathetic syndromes, the pathological changes in lower thoracic vertebra or lumbar vertebra should be taken in consideration.

    Although intracranial arachnoid cysts are a common incidental finding on pediatric brain imaging, only a subset of patients require surgery for them. For the minority who undergo surgery, the comparative effectiveness of various surgical approaches is debated. The authors explored predictors of surgery and compared operative techniques for pediatric patients with an intracranial arachnoid cyst seen at a tertiary care center. The authors reviewed records of pediatric patients with an intracranial arachnoid cyst. For each patient, data on baseline characteristics, the method of intervention, and surgical outcomes for the initial surgery were extracted, and cyst size at diagnosis was calculated (anteroposterior × craniocaudal × mediolateral). Baseline variables were analyzed as predictors of surgery by using logistic regression modeling, excluding patients whose surgery was not related to cyst size (i.e., those with obstructive hydrocephalus secondary to the cyst compressing a narrow CSF flow pathway or cyst rupture/hemorrhage). Data collected regarding surgical outcomes were analyzed descriptively. Among 83 pediatric patients with an intracranial arachnoid cyst seen over a 25-year period (1989-2013), 27 (33%) underwent surgery; all had at least 1 cyst-attributed symptom/finding. In the multivariate model, age at presentation and cyst size at diagnosis were independent predictors of surgery. Cyst size had greater predictive value; specifically, the area under the curve for the receiver-operating-characteristic curve was 0.89 (95% CI 0.82-0.97), with an ideal cutoff point of ≥ 68 cm(3). This cutoff point had 100% sensitivity (95% CI 79%-100%), 75% specificity (95% CI 61%-85%), a 53% positive predictive value (95% CI 36%-70%), and a 100% negative predictive value (95% CI 91%-100%); the positive likelihood ratio was 4.0 (95% CI 2.5-6.3), and the negative likelihood ratio was 0 (95% CI 0-0.3). Although the multivariate model excluded 7 patients who underwent surgery

    A retrocerebellar arachnoid cyst causing syringomyelia is extremely rare without tonsillar herniation. The authors present a 44-year-old woman with symptoms of foramen magnum compression and syringomyelia. Magnetic resonance imaging demonstrated a large retrocerebellar arachnoid cyst with a large cervicothoracic syrinx but no signs of tonsillar herniation or hydrocephalus. The patient underwent a foramen magnum decompression with C1 laminectomy, microsurgical fenestration of the cyst, and duraplasty. After successful reconstruction of CSF flow, the patient experienced a relief of symptoms and a significant reduction of the syrinx. The intraoperative findings support the theory of a piston mechanism in the development of syringomyelia. Additional arachnoidal adhesions may also obstruct the CSF flow around the craniocervical junction. We recommend the surgical treatment should consist of an adequate decompression of the foramen magnum, wide microsurgical arachnoidal debridement, and duraplasty with autologous grafts sutured in a watertight way.

    To summarize the clinical characteristics of intracranial arachnoid cysts (IACs) in pediatric cases. A retrospective analysis was carried out on clinical characteristics of IACs in 488 pediatric cases who were treated at our hospital from January 2003 to September 2013. There were 342 males and 146 females (male-to-female ratio, 2.34:1), aged 5.61±3.25 years on average. 221 cases (45.29%) were diagnosed accidentally, 267 cases had clinical complaints (54.71%), among which relationships between clinical complaints and IACs were identified in 123 (46.07%). Simple IACs occurred in 364 cases (4.59%), and concurrent congenital abnormalities occurred in 124 cases (4.59%). In terms of location, 355 had IACs in middle cranial fossa (72.75%), 82 cases in posterior cranial fossa (16.80%), 20 cases in anterior cranial fossa (4.10%), 12 cases in dorsolateral surface (2.46%), 7 cases in suprasellar cistern (1.43%), 5 cases in cerebral ventricle (1.02%), 5 cases in quadrigeminal cistern (1.02%), and 2 cases in interhemispheric region (0.41%). There were 449 cases with single IAC (92.01%) and 39 cases with multiple IACs (7.99%). On MRI, the cysts produced tension in 127 cases (26.02%), but not in the remaining 361 cases (73.98%). Surgery was performed on 76 of 488 cases (15.57%), while conservative observation was accepted in 412 cases (84.43%). For the former, the symptoms and the cyst volume were improved to varying extent; for the latter, the follow-up lasting for 3-72 months (average 32.43±8.92 months) showed that the cyst volume remained stable in 407 cases (98.78%), enlarged with aggravated symptoms in 3 cases (0.73%), and shrank in 2 cases (0.49%). Clinical complaints of IACs varied in pediatric cases, and the relationships between clinical complaints and IACs were established only partially. Some pediatric cases were combined with other congenital abnormalities. The cyst volume largely remained stable during the disease course, and surgery was required for only a few

    A 7-year-old male child presented with poorly controlled generalized tonic-clonic seizures. On examination, he was mentally retarded, deaf and had a swelling at the root on the nose. Computed tomography scan done previously revealed a left temporal arachnoid cyst (AC) due to which he was referred for surgery. However, magnetic resonance imaging revealed a constellation of abnormalities - all of which could be responsible for his seizures. The combination of periventricular nodular heterotopias with encepaholcele is rarely described in the literature, and more infrequently so its combination with AC and callosal dysgenesis - the Chudley-Mccullough syndrome. We describe the case and review relevant literature on this subject.

    Full Text Available Acquired cerebellar tonsillar herniation and syringomyelia associated with posterior fossa mass lesions is an exception rather than the rule. In the present article, we describe the neuroimaging findings in a case of 28-year-old female patient presented with a history of paraesthesia involving right upper limb of 8-month duration. Magnetic resonance imaging showed a giant retrocerebellar arachnoid causing tonsillar herniation with cervical syringomyelia. The findings in the present case supports that the one of the primary mechanism for the development of syringomyelia may be the obstruction to the flow of cerebrospinal fluid causing alterations in the passage of extracellular fluid in the spinal cord and leading to syringomyelia.

    Purpose: The purpose of this study is first to show the extent by which BLADE sequences can reduce all the image artifacts and second to verify that the usefulness of this technique in certain pathological conditions is significant. Methods: In this study, fourteen consecutive patients (5 females, 9 males), who routinely underwent MRI brain examination, between 2010–2014, were selected. The applied routine protocols for brain MR examination included the following sequences: 1) T2-W FLAIR axial; 2) T2-W TSE axial; 3) T2*-W axial, 4) T1-W TSE sagittal; 5) DWI-W axial; 6) T1-W TSE axial; 7) T1-W TSE axial+contrast. In cases of cystic tumors, the T2-W FLAIR BLADE sequence was added to the protocol. All the images were evaluated independently at two separate settings with 3 weeks interval by two radiologists. The radiologists also evaluated the presence of image artifacts (motion, flow, chemical shift, Gibbs ringing). To evaluate the size of the cyst, the two radiologists compared the two techniques (conventional and BLADE) by assessing the extent of the divergence in the measurements of the cysts. Results: Regarding the extent of the cyst size, BLADE measurements were found to be more reliable than the conventional ones with the differences being statistically significant (p<0.01). The qualitative measurements indicated that the T2 FLAIR BLADE sequences were superior to the conventional T2 FLAIR with statistically significant differences (p<0.001) in the following characteristics: 1) overall image quality, 2) CSF nulling; 3) contrast at the pathology and its surrounding; 4) limits of the pathology; 5) motion artifacts; 6) flow artifacts; 7) chemical shift artifacts and 8) Gibbs ringing artifacts. Conclusion: BLADE sequence was found to decrease both flow artifacts in the temporal lobes and motion artifacts from the orbits and it is proposed for clinical use.

    Full Text Available Abstract Background The mechanisms behind formation and filling of intracranial arachnoid cysts (AC are poorly understood. The aim of this study was to evaluate AC fluid by proteomics to gain further knowledge about ACs. Two goals were set: 1 Comparison of AC fluid from individual patients to determine whether or not temporal AC is a homogenous condition; and 2 Evaluate the protein content of a pool of AC fluid from several patients and qualitatively compare this with published protein lists of cerebrospinal fluid (CSF and plasma. Methods AC fluid from 15 patients with temporal AC was included in this study. In the AC protein comparison experiment, AC fluid from 14 patients was digested, analyzed by LC-MS/MS using a semi-quantitative label-free approach and the data were compared by principal component analysis (PCA to gain knowledge of protein homogeneity of AC. In the AC proteome evaluation experiment, AC fluid from 11 patients was pooled, digested, and fractionated by SCX chromatography prior to analysis by LC-MS/MS. Proteins identified were compared to published databases of proteins identified from CSF and plasma. AC fluid proteins not found in these two databases were experimentally searched for in lumbar CSF taken from neurologically-normal patients, by a targeted protein identification approach called MIDAS (Multiple Reaction Monitoring (MRM initiated detection and sequence analysis. Results We did not identify systematic trends or grouping of data in the AC protein comparison experiment, implying low variability between individual proteomic profiles of AC. In the AC proteome evaluation experiment, we identified 199 proteins. When compared to previously published lists of proteins identified from CSF and plasma, 15 of the AC proteins had not been reported in either of these datasets. By a targeted protein identification approach, we identified 11 of these 15 proteins in pooled CSF from neurologically-normal patients, demonstrating that

    Introduccion. Los quistes aracnoideos bilaterales del angulo pontocerebeloso son excepcionales, y unicamente existen tres casos publicados en la bibliografia. Caso clinico. Niña de 14 años, previamente sana, que acude a consultas por presentar cefalea bifrontal de seis semanas de evolucion. La exploracion clinica era normal y la resonancia magnetica craneal mostraba dos lesiones extraaxiales localizadas en ambos angulos pontocerebelosos, siendo ligeramente mayor la izquierda. Las lesiones se comportaban como homogeneamente intensas en T1 e hiperintensas en T2, no captaban contraste y no existia restriccion en las secuencias de difusion. No se indico tratamiento quirurgico. Conclusiones. Los quistes aracnoideos bilaterales situados en el angulo pontocerebeloso son excepcionales. La principal indicacion para el tratamiento quirurgico es la presencia de sintomas o signos neurologicos coincidentes con la localizacion de los quistes.

    The aim of this study was to evaluate and validate the Cambridge Neuropsychological Test Automated Battery (CANTAB) in a Norwegian group of patients undergoing surgery for middle fossa arachnoid cysts (AC). We also wanted to assess health related quality of life (HRQOL) in these patients to see if it could be improved by decompression of the AC. Adult patients (>18 years) with unilateral middle fossa AC and no previous history of neurological disease, head injury, or a psychiatric disorder were eligible for inclusion. We used four tests from CANTAB to assess the level of neuropsychological performance: paired associate learning (PAL) and delayed matching to sample (DMS) assessed temporal lobe functions, while Stockings of Cambridge (SOC) and intra-extra dimensional (IED) shift focused on frontal lobe functions. Patients with postoperative cerebral complications were reported, but excluded from neuropsychological follow-up. In addition to the CANTAB data, pre- and postoperative clinical and radiological data were collected. HRQOL was assessed using Short Form 36 (SF-36) pre- and postoperatively. We found significant improvement in the two temporal tests assessing memory, but no improvement in the two frontal tests assessing executive function. HRQOL was significantly reduced preoperatively in two of eight SF-36 domains and improved significantly in four domains postoperatively. CANTAB facilitates detection of cognitive improvements after decompression of the cyst in patients with AC in the middle fossa. The improvements were detected on the tests sensitive to temporal lobe problems only, not on the tests more sensitive to frontal lobe affection. This establishes construct validity for CANTAB for the first time in this population.

    The authors report their experience concerning 75 cases of middle fossa arachnoid cysts observed in children during the period 1975-1993, 47 of which (62.6%) were operated upon. The aim of this study was to study the clinical presentation of these cysts, to discuss the surgical indications and to compare the results of the various techniques used to treat these malformations. Head injury was revealing in 17 cases (22.6%) and among these, 12 patients presented intracranial complications (subdural effusions; 6 cases, subdural hematomas: 4 cases and intracystic hematomas: 2 cases). The most usual signs and symptoms were: intracranial hypertension (25.3%), epilepsy (16%) and temporal bulging (24%). Twenty-one patients (44.7%) underwent a cystoperitoneal shunt; 20 patients (42.5%) were treated by membranectomy with opening of the basal cisterns and removal of intracystic (2 cases) or subdural hematoma (4 cases); 2 patients (4.3%) were treated using membranectomy, opening of the cisterns and cystoperitoneal shunt and 4 patients (8.4%) underwent a subduroperitoneal shunt. The long-term results were good regardless of the surgical procedure; nevertheless, only one patient among 20 cases treated by membranectomy and opening of the cisterns developped complications (5%), while multiple shunt revisions were necessary in 11 children (40.7%) out of 27 where a shunt was inserted. The authors conclude that membranectomy and opening of the basal cisterns is the procedure of choice to treat middle fossa arachnoid cysts in children.

    Full Text Available It is known that the caudal dislocation of the cerebellar tonsils may occur associated with clinical conditions such as an intracranial mass lesion or Chiari I and II malformation. It may also be acquired after repeated lumbar punctures or lumboperitoneostomy. The occurrence of cerebellar herniation after derivation of intracranial arachnoid cyst is extremely rare, and there are only three cases reported in the medical literature. We present the case of a 9-year-old boy with precocious puberty and suprasellar arachnoid cyst who developed a symptomatic herniation of the cerebellar tonsils three years after a cystoperitoneostomy. The patient underwent a suboccipital craniectomy with duraplasty and partial tonsilectomy, showing afterwards, remission of the symptoms. We discussed the pathogenesis suggested in the literature.Sabe-se que o deslocamento caudal das tonsilas cerebelares pode ocorrer em associação com condições clínicas tais como: lesão expansiva intracraniana ou malformação de Chiari I e II. Pode ainda ser adquirido após repetidas punções lombares ou lomboperitoniostomia. A ocorrência de herniação cerebelar após derivação de cisto aracnóide intracraniano é evento extremamente raro, existindo apenas três casos relatados na literatura médica. O caso de menino de 9 anos de idade, com puberdade precoce e cisto aracnóide supra-selar, que desenvolveu herniação sintomática das tonsilas cerebelares três anos após cistoperitoniostomia. O paciente foi submetido a craniectomia suboccipital com plástica dural e tonsilectomia parcial, apresentando remissão dos sintomas. Discutimos a patogênese sugerida na literatura.

    Spinal arachnoiditis describes inflammation of the meninges, subarachnoid space and, in most cases, also involve the pial layer. The vast majority of cases described are secondary and are preceded by a known event, for example,. trauma, infections or irritative substances. Here, we present the case of primary spinal arachnoiditis. A 35-year-old lady was referred to the neurosurgical services in Dublin, Ireland with a 15-month history of progressive, right lower limb weakness. Magnetic resonance imaging revealed cystic distortion of the lumbar spinal canal extending up to the conus. Initially, an L2-L4 laminectomy was performed revealing thickened and adherent arachnoid with a large cyst in the spinal canal. Four months after initial operation, the patient represented with bilateral lower limb weakness and loss of detrusor function. Repeat magnetic resonance imaging was performed, which showed the development of a syrinx in the patient\\'s thoracic spine. We then performed a T9-T10 laminectomy, midline myelotomy and insertion of a syringe-arachnoid shunt. Post-operative imaging showed resolution of the syrinx and a vast improvement in lower limb power. The patient also regained bladder control. In conclusion, spinal arachnoiditis is a clearly defined pathological and radiological entity with a highly variable clinical presentation. It is exceedingly difficult to treat as there is no recognised treatment currently, with most interventions aimed at symptomatic relief.

    The intestinal parasites Cryptosporidium and Giardia are transmitted by water and food and cause human gastroenteritis. Filter-feeding bivalve mollusks, such as oysters and mussels, filter large volumes of water and thus concentrate such pathogens, which makes these bivalves potential vectors of disease. To assess the risk of infection from consumption of contaminated bivalves, parasite numbers and parasite recovery data are required. A modified immunomagnetic separation (IMS) procedure was used to determine Cryptosporidium oocyst and Giardia cyst numbers in individually homogenized oysters (Crassostrea gigas) and mussels (Mytilus edulis). About 12% of the commercial bivalves were positive, with low (oo)cyst numbers per specimen. The recovery efficiency of the IMS procedure was systematically evaluated. Experiments included seeding of homogenized bivalves and whole animals with 100 to 1,000 (oo)cysts. Both seeding procedures yielded highly variable recovery rates. Median Cryptosporidium recoveries were 7.9 to 21% in oysters and 62% in mussels. Median Giardia recoveries were 10 to 25% in oysters and 110% in mussels. Giardia recovery was significantly higher than Cryptosporidium recovery. (Oo)cysts were less efficiently recovered from seeded whole animals than from seeded homogenates, with median Cryptosporidium recoveries of 5.3% in oysters and 45% in mussels and median Giardia recoveries of 4.0% in oysters and 82% in mussels. Both bivalve homogenate seeding and whole animal seeding yielded higher (oo)cyst recovery in mussels than in oysters, likely because of the presence of less shellfish tissue in IMS when analyzing the smaller mussels compared with the larger oysters, resulting in more efficient (oo)cyst extraction. The data generated in this study may be used in the quantitative assessment of the risk of infection with Cryptosporidium or Giardia associated with the consumption of raw bivalve mollusks. This information may be used for making risk management

    Opalak, Charles F.; Opalak, Michael E.

    2015-01-01

    Background: Arachnoiditis ossificans (AO) is a rare disorder that was differentiated from leptomeningeal calcification by Kaufman and Dunsmore in 1971. It generally presents with progressive lower extremity myelopathy. Though the underlying etiology has yet to be fully described, it has been associated with various predisposing factors including vascular malformations, previous intradural surgery, myelograms, and adhesive arachnoiditis. Associated conditions include syringomyelia and arachnoid cyst. The preferred diagnostic method is noncontrast computed tomography (CT). Surgical intervention is still controversial and can include decompression and duroplasty or durotomy. Case Description: The authors report the case of a 62-year-old male with a history of paraplegia who presented with a urinary tract infection and dysautonomia. His past surgical history was notable for a C4–C6 anterior fusion and an intrathecal phenol injection for spasticity. A magnetic resonance image (MR) also demonstrated a T6-conus syringx. At surgery, there was significant ossification of the arachnoid/dura, which was removed. After a drain was placed in the syrinx, there was a significant neurologic improvement. Conclusion: This case demonstrates a unique presentation of AO and highlights the need for CT imaging when a noncommunicating syringx is identified. In addition, surgical decompression can achieve good results when AO is associated with concurrent compressive lesions. PMID:26693389

    Human and porcine cysticercosis is caused by the larval stage of the flatworm Taenia solium (Cestoda). The protein extracts of T. solium cysts are complex mixtures including cyst's and host proteins. Little is known about the influence of using different detergents in the efficiency of solubilization-extraction of these proteins, including relevant antigens. Here, we describe the use of CHAPS, ASB-14 and Triton X-100, alone or in combination in the extraction buffers, as a strategy to notably increase the recovery of proteins that are usually left aside in insoluble fractions of cysts. Using buffer with CHAPS alone, 315 protein spots were detected through 2D-PAGE. A total of 255 and 258 spots were detected using buffers with Triton X-100 or ASB-14, respectively. More protein spots were detected when detergents were combined, i.e., 2% CHAPS, 1% Triton X-100 and 1% ASB-14 allowed detection of up to 368 spots. Our results indicated that insoluble fractions of T. solium cysts were rich in antigens, including several glycoproteins that were sensitive to metaperiodate treatment. Host proteins, a common component in protein extracts of cysts, were present in larger amounts in soluble than insoluble fractions of cysts proteins. Finally, antigens present in the insoluble fraction were more appropriate as a source of antigens for diagnostic procedures.

    Gliomas are the most common infiltrative neoplasms of the optic nerve and can present as two distinct growth patterns: intraneural glial proliferation and perineural arachnoidal gliomatosis (PAG). It has been suggested that perineural arachnoidal gliomatosis is seen almost exclusively in the setting of neurofibromatosis type 1 (NF1). We describe a child with perineural arachnoidal gliomatosis occurring without neurofibromatosis type 1, supported by both radiographic and histological findings....

    We reviewed the MRI of seven patients with syringomyelia associated with surgically proven adhesive spinal arachnoiditis to describe clinical and MRI findings in this condition. Using 0.5, 1.0 or 1.5 tesla units, we obtained sagittal T1- and T2-weighted spin-echo and axial T1-weighted images. Additional sagittal T2-weighted images were obtained without using motion-artefact suppression. Contrast medium was given intravenously to five patients. The syrinx cavities were thoracic in five cases, cervicothoracic in one, and extended from C4 to L1 in one. No Chiari malformation or craniovertebral junction anomaly was demonstrated. Meningeal thickening was seen on T2-weighted sagittal images only in one case. Cord deformity due to adhesion or displacement due to an associated arachnoid cyst was seen in all cases best demonstrated on axial images. Focal blurring of the syrinx wall on axial images was seen in six patients. Flow voids were seen in the syrinx fluid in all cases on T2-weighted images obtained without motion-artefact suppression. No abnormal contrast enhancement was demonstrated. (orig.)

    Arachnoiditis involving optic nerve and the optic chiasm can occur as a complication of tuberculous meningitis (TBM). This study evaluates the clinical features, cerebrospinal fluid (CSF) and laboratory parameters and imaging findings of optochiasmatic arachnoiditis (OCA) and also tried to identify any factors which can predict this complication in patients with TBM. Patients admitted with TBM in the neurology wards of a tertiary care teaching hospital over a period of 6 years formed the material for this study. Student's "t" test and univariate analysis were done to identify any predictors for this complication and the variables found to be significant were further analyzed by multivariate logistic regression analysis. One hundred sixty-three patients with TBM, admitted over a 6-year period, were studied. Twenty-three (14%) patients developed OCA. Eighteen out of 23 (78%) developed this complication while on antituberculous treatment (ATT) and 5/23 (22%) were newly diagnosed cases of TBM. Of those already on treatment, 12/23 (52%) were receiving only ATT, the remaining 6/23 (26%) had received steroids along with ATT in varying doses and duration. The average period from diagnosis of TBM to visual symptoms was 6.4 months. On the multivariate logistic regression analysis, female sex (P 260 mg% (P < 0.021) were the factors predisposing toward this complication. At 6 months follow-up, on treatment with steroids and ATT, 17% had improvement and no further deterioration was noted in visual acuity in 52%. OCA can develop even while on treatment with ATT. Young women with a high CSF protein content seem to be more prone for this complication.

    disabilities. On physical examination he exhibited mild eunuchoid aspect, 162 cm height (z score = -2,17, pubertal development on stage G II, P II, and 4 cm5 testis. Laboratory investigation revealed pre-pubertal levels of testosterone and normal results of the combined test of anterior pituitary function, except for in GnRH acute and prolonged test. Brain CT showed an arachnoid cyst on left middle fossa with expansion to suprasellar cisterna. He was diagnosed as having hypogonadotrophic hypogonadism secondary to compression by the cyst, and a cyst-peritoneal derivation was performed. After surgery there was no improvement of the pubertal state and bilateral anosmia was discovered, so Kallmann's syndrome was then diagnosed and was confirmed by MRI, even though the hormonal results are not totally matched with the refered syndrome. We did not find in the literature any description of the association between Kallmann's syndrome and arachnoid cyst and we believe that in this case the results of the hormonal measurement may be due to such association that provoked an additional hypophysis dysfunction.

    A continuous microwave system to treat ballast water inoculated with Artemia salina cysts as a model invasive spore was tested for its efficacy in inactivating the cysts present. The system was tested at two different flow rates (1 and 2 L x min(-1)) and two different power levels (2.5 and 4.5 kW). Temperature profiles indicate that the system could deliver heating loads in excess of 100 degrees C in a uniform and near-instantaneous manner when using a heat recovery system. Except for a power and flow rate combination of 2.5 kW and 2 L x min(-1), complete inactivation of the cysts was observed at all combinations at holding times below 100 s. The microwave treatment was better or equal to the control treatment in inactivating the cysts. Use of heat exchangers increased the power conversion efficiency and the overall efficiency of the treatment system. Cost economics analysis indicates that in the present form of development microwave treatment costs are higher than the existing ballast water treatment methods. Overall, tests results indicated that microwave treatment of ballast water is a promising method that can be used in conjunction with other methods to form an efficient treatment system that can prevent introduction of potentially invasive spore forming species in non-native waters.

    A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for different cysts, such as congenital, trauma, bleeding, inflammatory, instability, hydrostatic pressure, osmosis of water, secretion of cyst wall, and one-way-valve effect, etc. Up to now, many treatment methods are available for these different spinal canal cysts. One operation method can be applied in cysts with different types. On the other hand, several operation methods may be utilized in one type of cyst according to the difference of location or style. However, same principle should be obeyed in surgical treatment despite of difference among spinal canal cysts, given open surgery is melely for symptomatic cyst. The surgical approach should be tailored to the individual patient.

    This is the first report of a case of sacral radicular cysts in a patient with autosomal dominant polycystic kidney disease (ADPKD). A 46-year-old woman with ADPKD was found to have bilateral sacral radicular cysts discovered incidentally by magnetic resonance imaging (MRI). Cysts arising from arachnoid or spinal meningeal sac should be considered one of the manifestations of a more widespread connective tissue disorder associated with ADPKD.

    Lumbosacral perineural cysts are formed by the arachnoid membrane of the nerve root at the lumbosacral level. Most of these cysts are asymptomatic and are found incidentally during computed tomography (CT) or magnetic resonance imaging (MRI) for other causes of chronic lower back pain. This type of cyst requires a differential diagnosis to distinguish it from other causes of radiating pain and neurological symptoms. In the present case, a symptomatic lumbosacral perineural cyst was found, and pain relief was achieved by non-surgical treatment. A lumbosacral perineural cyst was identified from a differential diagnosis of a lumbar disc disorder that presented as radiating pain and neurological symptoms. PMID:22679550

    Although the arachnoid membranes have been known for more than 300 years, the anatomy of the arachnoid membranes has not been studied in detail. This study was performed to explore the microanatomical features of the cranial arachnoid membranes. The arachnoid membranes and cisterns were observed in eight Han Chinese adult human cadaveric brains with an operating microscope, without staining of intracranial structures or injection of colored material into blood vessels. Twenty seven arachnoid membranes and 21 subarachnoid cisterns were identified. The topographical features of each arachnoid membrane were described. On the basis of the arachnoid membranes we identified, the arachnoidal limits of the cisterns were discussed. The microsurgical anatomical research on the arachnoid membranes is a supplement to the anatomical study of the subarachnoid cisterns. The understanding of the topographical features of the arachnoid membranes is valuable to the reasonable dissection of the cisterns and the minimally invasive manipulations during microsurgical procedures.

    Full Text Available The purpose of this study was to investigate using light microscopy the fibro-cellular components of arachnoid granulations affected by mild and severe subarachnoid hemorrage. The erythrocytes were in the channels delimitated by collagenous and elastic bundles and arachnoid cells, showing their tortuous and intercommunicating row from the pedicle to the fibrous capsule. The core portion of the pedicle and the center represented a principal route to the bulk outflow of cerebrospinal fluid and erythrocytes. In the severe hemorrhage, the fibrocellular components are desorganized, increasing the extracellular channels. We could see arachnoid granulations without erythrocytes, which cells showed big round nucleous suggesting their transformation into phagocytic cells.

    Spinal arachnoiditis is one of the common and disabling complication of tuberculous meningitis (TBM). We focused on early diagnosis of spinal arachnoiditis by spinal MRI in asymptomatic patients in whom neurological examination was normal. We studied 16 patients with a diagnosis of probable or highly probable TBM with symptoms for less than 1 month; three had radiological evidence of spinal arachnoiditis. High cerebrospinal fluid protein appeared to be a risk factor for development of spinal arachnoiditis. MRI is sensitive to detect early spinal arachnoiditis. Earlier diagnosis may be helpful in management of spinal arachnoiditis in TBM. (orig.)

    BACKGROUND: This paper describes histomorphologic studies on arachnoid granulations in rats, which have not been investigated in China to our knowledge.OBJECTIVE: To observe the distribution of intracranial arachnoid granulations in rats. DESIGN, TIME AND SETTING: The observational experiment was performed in the Academy of Life Sciences of Shandong Taishan Medical College from May to August 2004.MATERIALS: Thirty healthy adult Wistar rats (3-4 months old) of SPF grade, equal numbers of each sex, were selected for this study. Methylene blue parenteral solution was provided by Jiangsu Jichuan Pharmaceutical Company (China), and an optical microscope (Type: CH20; Olympus Co. Ltd., Japan) was used for observation of the histomorphology of the arachnoid granulations.METHOD: Injection of methylene blue parenteral solution into the cerebellomedullary cistern of rats.MAIN OUTCOME MEASURE: The blue stained parts of the lateral sinus were sectioned, stained by hematoxylin and eosin, and then observed under the microscope.RESULTS: The cavitas subarachnoidealis had extensive blue staining after methylene blue injection, while the arachnoid and dura were without dye accumulation. The blue dye indicated the location of the arachnoid granulations. The location of these granulations was fixed, mainly in the lateral sinus at both sides of confluence within 4 mm of the internal jugular vein.CONCLUSION: The arachnoid granulations of the rat were located mainly in the lateral sinuses of the dura mater.

    Although the histogenesis of meningiomas remains unclear, it is believed that arachnoid cells are the most likely origin of this type of neoplasm. Further, little attention has been paid to the histopathology of spinal meningiomas arising from the arachnoid villi. We came across a case of spinal meningioma that was locally attached to the arachnoid membrane. The associated arachnoid villi were investigated by light microscopy and immunohistochemical analysis. We confirmed the presence of tumor cells under the fibrous capsule that forms the outer component of the arachnoid villi. Tumor cells grew out from the apical portion of the arachnoid villi. Furthermore, immunohistochemical study suggested that arachnoid cells made the transition to tumor cells on the arachnoid cell layer.

  9. Spinal perineurial and meningeal cysts

    Tarlov, I. M.

    1970-01-01

    Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fails to reveal an adequate cause for the patient's symptoms and signs referable to the caudal nerve roots, then about a millilitre of Pantopaque should be left in the canal for delayed myelography which may later reveal a sacral perineurial cyst or, occasionally, a meningeal cyst. Meningeal diverticula occur proximal to the posterior root ganglia and usually fill on initial myelography. They are in free communication with the subarachnoid space and are rarely in my experience responsible for clinical symptoms. Meningeal diverticula and meningeal cysts appear to represent a continuum. Pantopaque left in the subarachnoid space may convert a meningeal diverticulum into an expanding symptomatic meningeal cyst, as in the case described. Many cases described as perineurial cysts represent abnormally long arachnoidal prolongations over nerve roots or meningeal diverticula. In general, neither of the latter is of pathological significance. Perineurial, like meningeal cysts and diverticula, may be asymptomatic. They should be operated upon only if they produce progressive or disabling symptoms or signs clearly attributable to them. When myelography must be done, and this should be done only as a preliminary to a probable necessary operation, then patient effort should be made to remove the Pantopaque. Images PMID:5531903

    The cistern of the velum interpositum is a space located between the corpus callosum dorsally and the roof of the third ventricle ventrally. Lesions located within the velum interpositum are rare and include meningiomas, pilocytic astrocytomas, atypical teratoid/rhabdoid tumors and arachnoid cysts. Epidermoid cysts in this location have not been reported previously. We report the clinical and radiological features of two patients with epidermoid cysts located in the velum interpositum. The patients presented with gait difficulty and features of raised intracranial pressure and magnetic resonance imaging demonstrated large tumors in the velum interpositum with intensities suggestive of epidermoid cysts. There was ventral displacement of the internal cerebral veins and dorsal displacement of the corpus callosum in keeping with a mass in the velum interpositum. Tumors of the third ventricle displace the internal cerebral veins dorsally. A transcallosal approach was used in both patients to effectively excise the tumors.

  11. Neurologic deficits and arachnoiditis following neuroaxial anesthesia.

    Science.gov (United States)

    Aldrete, J A

    2003-01-01

    Of late, regional anesthesia has enjoyed unprecedented popularity; this increase in cases has brought a higher frequency of instances of neurological deficit and arachnoiditis that may appear as transient nerve root irritation, cauda equina, and conus medullaris syndromes, and later as radiculitis, clumped nerve roots, fibrosis, scarring dural sac deformities, pachymeningitis, pseudomeningocele, and syringomyelia, etc., all associated with arachnoiditis. Arachnoiditis may be caused by infections, myelograms (mostly from oil-based dyes), blood in the intrathecal space, neuroirritant, neurotoxic and/or neurolytic substances, surgical interventions in the spine, intrathecal corticosteroids, and trauma. Regarding regional anesthesia in the neuroaxis, arachnoiditis has resulted from epidural abscesses, traumatic punctures (blood), local anesthetics, detergents, antiseptics or other substances unintentionally injected into the spinal canal. Direct trauma to nerve roots or the spinal cord may be manifested as paraesthesia that has not been considered an injurious event; however, it usually implies dural penetration, as there are no nerve roots in the epidural space posteriorly. Sudden severe headache while or shortly after an epidural block using the loss of resistance to air approach usually suggests pneumocephalus from an intradural injection of air. Burning severe pain in the lower back and lower extremities, dysesthesia and numbness not following the usual dermatome distribution, along with bladder, bowel and/or sexual dysfunction, are the most common symptoms of direct trauma to the spinal cord. Such patients should be subjected to a neurological examination followed by an MRI of the effected area. Further spinal procedures are best avoided and the prompt administration of IV corticosteroids and NSAIDs need to be considered in the hope of preventing the inflammatory response from evolving into the proliferative phase of arachnoiditis.

    2011-11-01

    Full Text Available The most important restriction for the detection in water samples is the low concentration of Giardia intestinalis cysts, additional difficulty is the presence of PCR inhibitors. We have carried out trials in order to assess the sensitivity of semi-nested PCR and TaqMan real time PCR on the basis of DNA extracted from G. intestinalis cysts coming from spiked environmental and distilled water samples, filtrated with the use of Filta-Max® equipment (1623 Method. Removal of inhibitors was carried out with addition of BSA in different concentrations. During the filtration and concentration of water samples, losses of cysts have been recorded. Moreover, addition of BSA to the PCR and real time PCR mix increases the sensitivity of reaction. The optimal concentration of BSA for semi-nested PCR was 15 and 20 ng/μl, whereas for real time PCR 5 ng/μl.

    We report magnetic resonance (MR), computed tomography (CT) and angiographic imaging of an unusual giant arachnoid granulation in the superior sagittal sinus in a man with headache and vertigo. Intrasinus pressure measurements revealed a significant pressure gradient across the lesion. MR imaging is useful to identify giant arachnoid granulation and dural sinus thrombosis, whereas dural sinus pressure measurement in certain cases of giant arachnoid granulations can be used to evaluate the lesion as the cause of the patient's symptoms.

  16. Intracranial neurenteric cyst traversing the brainstem

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Neurenteric cysts (NECs, also called enterogenous cysts, are rare benign endodermal lesions of the central nervous system that probably result from separation failure of the notochord and upper gastrointestinal tract. Most frequently they are found in the lower cervical spine or the upper thoracic spine. Intracranial occurrence is rare and mostly confined to infratentorial compartment, in prepontine region [51%]. Other common locations are fourth ventricle and cerebellopontine angle. There are few reports of NEC in medulla or the cerebellum. Because of the rarity of the disease and common radiological findings, they are misinterpreted as arachnoid or simple cysts until the histopathological confirmation, unless suspected preoperatively. We herein report a rare yet interesting case of intracranial NEC traversing across the brainstem.

    Arachnoid granulations (AG) are composed of dense, collagenous connective tissue that includes clusters of arachnoid cells. They tend to invaginate into the dural sinuses, through which cerebrospinal fluid enters the venous system. AG are most commonly seen at the junction between the middle and lateral thirds of the transverse sinuses near the entry sites of the superficial veins. Presently described is the case of a 21-year-old female who presented at the clinic with recurrent headaches. Magnetic resonance (MR) imaging revealed a 3.5-cm lesion, which extended from confluens sinuum through the superior sagittal sinus. The lesion had created a scallop-shaped area of erosion in the neighboring occipital bone. To exclude sinus thrombosis, MR venography was performed, which displayed a maintained venous flow around the lesion. Headaches were treated symptomatically with medical therapy. Giant AG can be misdiagnosed as dural sinus thrombosis. MR imaging combined with MR venography is the most useful diagnostic tool to differentiate giant AG from dural sinus thrombosis.

    An 11-week-old, male, Staffordshire Bull Terrier had a history of generalized ataxia and falling since birth. The neurologic findings suggested a localization in the cerebellum. Magnetic resonance imaging of the brain was performed. In all sequences the area of the cerebellum was almost replaced by fluid isointense to cerebrospinal fluid. A complete necropsy was performed after euthanasia. Histologically, the lesion was characterized by extensive loss of cerebellar tissue in both hemispheres and vermis. Toward the surface of the cerebellar defect, the cavity was confined by ruptured and folded membranes consisting of a layer of glial fibrillary acidic (GFAP)-positive glial cells covered multifocally by epithelial cells. Some of these cells bore apical cilia and were cytokeratin and GFAP negative, supporting their ependymal origin. The histopathologic features of our case are consistent with the diagnosis of an ependymal cyst. Its glial and ependymal nature as demonstrated by histopathologic and immunohistochemical examination differs from arachnoid cysts, which have also been reported in dogs. The origin of these cysts remains controversial, but it has been suggested that they develop during embryogenesis subsequent to sequestration of developing neuroectoderm. We speculate that the cyst could have been the result of a pre- or perinatal, possibly traumatic, insult because hemorrhage, and tissue destruction had occurred. To our knowledge, this is the first description of an ependymal cyst in the veterinary literature.

    Arachnoid granulations are structures filled with cerebrospinal fluid (CSF) that extend into the venous sinuses through openings in the dura mater and allow the drainage of CSF from subarachnoid space into venous system. Usually they are asymptomatic but can be symptomatic when large enough to cause sinus occlusion. We report a rare case of a brain herniation into a giant arachnoid granulation in an asymptomatic elderly male patient, which was discovered incidentally. PMID:28392955

    1983-01-01

    14 young patients, operated upon for opto-chiasmatic arachnoiditis by craniotomy are presented. 2 main etiopathogenetic forms (and their respective clinical equivalents) of the disease could be recognized. Only 1 postoperative death occurred, in a patient with a dominant clinical picture of intracranial hypertension. Results of surgery (craniotomy and lysis of adhesions) could be distinguished as positive (functional improvement) in 5 cases, indifferent or negative in the others, with a follow-up duration of up to 23 years. The role of the diagnostic value of the pneumoencephalogram as a basis for surgical indication is discussed: it is felt that this examination, when reported as negative, is not of sufficient value to rule out the diagnosis, which must essentially rely upon clinical data.

    The examination and treatment of 66 patients with rhinosinusogenic cerebral arachnoiditis (RCA) were performed using otorhinolaryngological and neurological tests with special emphasis on pneumoencephalography to provide objective assessment of the brain layers and ventricles. It is shown that RCA occurs most frequently in subjects suffering from chronic purulent axillary sinusitis or recurrent polysinusitis. RCA manifestations depend on the duration of rhinosinusitis and its recurrence rate. RCA onset is usually not acute and takes place at the time of rhinosinusitis exacerbation. There are also mild frontal headaches, pathological changes in the coats of the anterior cranial fossa. The above abnormalities were most pronounced at the side of rhinosinusitis or most affected sinus. The treatment should be first of all oriented on elimination of maxillary infection in line with pathogenetic treatment of RCA. An individual approach to treatment policy is advocated.

    We report the results of a MR velocity study of the cerebrospinal fluid including 36 patients with syringomyelic cysts (25 with a foraminal syringomyelia, 7 with a post-traumatic cyst, 2 with a tumoral spinal cord cyst, 2 with a spinal arachnoiditis). Velocity measurements were performed in the cysts and in the pericystic subarachnoid spaces and compared with clinical data, evolutive pattern of the disease, cyst volume, degree of stenosis of the cranio-cervical junction (in patients with Chiari I) or of the spinal canal (in post-traumatic cases), and with the extension of the cyst (post-traumatic cases). Cyst velocities correlated in the pre operative course with the clinical status of the patients and with the volume of the cyst. Correlation with the degree of foraminal stenosis was uncertain and no correlation was found with the duration of the disease course. In the post-operative course cyst velocity decreased and velocity of the subarachnoid spaces increased. Onset of the systolic peak occurred sooner in the cyst than in the subarachnoid spaces. We believe that this point may be important in the pathogenesis of the disease. We consider that systolic and diastolic cyst velocities respectively greater than 2.3 cm/s and 1.5 cm/s in the post-operative course may characterize aggressive cysts. In the future comparison of velocity measurements in patients with Chiari I without syrinx and patients with Chiari I related syringomyelia may be helpful for a better understanding of the natural history of the syringomyelia.

  8. Factors affecting recovery efficiency in isolation of Cryptosporidium oocysts and Giardia cysts from vegetables for standard method development.

    Robertson, L J; Gjerde, B

    2001-11-01

    While recently published techniques for recovering parasites from fruits and vegetables demonstrate a marked increase in efficiency and utility, there is still scope for further improvement in developing a standard method, particularly with difficult, but important, sample matrices such as bean sprouts. Herein, a number of parameters used in published techniques are investigated more closely. While sample size reduction may improve recovery efficiency because of a range of factors, it is important to keep the sample large enough for detection of low-level contamination. Age of sample is also important, and samples should be as fresh as possible. Elution procedures may contribute to losses of Giardia and should be more thoroughly investigated. Improved immunomagnetic separation techniques currently coming onto the market also have the potential to increase recovery efficiency substantially, even with difficult samples such as aged bean sprouts. However, merely increasing magnetic strength of the capturing magnet does not affect recovery efficiency, which must be reliant on a superior bead system, buffering system, or both.

    Full Text Available Background: Adhesive arachnoiditis is a chronic, insidious condition that causes debilitating intractable pain and a range of other neurological problems. Its pathophysiology is not well understood. This manuscript discusses its presentations, which can mimic an acute spinal disorder, its hypothetical pathophysiology, treatment, and its relationship with fibromyalgia. Case Description: The authors present a case of a 47-year-old female who presented with clinical features mimicking an acute spinal disorder but later found to have an adhesive arachnoiditis. She was admitted following a trauma with complaints of back pain and paraplegia. On examination, there was marked tenderness over thoracolumbar spine with lower limbs upper motor neuron weakness. An urgent magnetic resonance imaging (MRI of the spine revealed multiple lesions at her thoracic and lumbar spinal canals, which did not compress the spinal cord. Therefore, conservative management was initiated. Despite on regular therapies, her back and body pain worsened and little improvement in her limbs power was noted. Laminectomy was pursued and found to have spinal cord arachnoiditis. Subsequently, she was operated by other team members for multiple pelvic masses, which later proved to be benign. After gathering all the clinical information obtained at surgery and after taking detailed history inclusive of cognitive functions, diagnosis of an adhesive arachnoiditis syndrome was made. Currently, she is managed by neuropsychologist and pain specialist. Conclusion: This case report highlights the importance of knowing an adhesive arachnoiditis syndrome - a rarely discussed pathology by the neurosurgeon, which discloses a significant relationship between immune and nervous systems.

    Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities, but the latter may be absent in adults. Although usually located in the thorax, neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain, nausea, vomiting, low grade fever and leucocytosis. She underwent cystgastrostomy for a loculated cyst of the distal pancreas at the age of 4 years, which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy (CT) scan revealed a 16cm×15cm cystic mass in the body and tail of pancreas, with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision, and after an uneventful recovery, remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200mL of pale viscous fluid. It was covered by a primitive singlelayered cuboidal epithelium, along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resembling those of the body of the stomach were also seen. In addition, ciliary respiratory epithelium, foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer, neuroglial tissue with plexogenic nerve fascicles, Paccini corpuscle-like structures, hyperplastic neuroganglionar elements and occasional psammomatous bodies, as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100, GFAP, NF and NSE. The gastric epithelium showed mostly CK7 and EMA

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used.

  19. Arachnoid granules: Dandy was Dandy, Cushing and Weed were not.

    Science.gov (United States)

    Maurizi, Charles P

    2010-08-01

    Errors can be instructive. It seems that Harvey Cushing and Louis Weed provided the medical world with a faulty theory of cerebrospinal fluid absorption. Louis Weed, working in Harvey Cushing's laboratory, initially studied the movement of substances in the cerebrospinal fluid by using low-pressure studies. Results of the low-pressure studies were considered unsatisfactory and high pressure experiments were undertaken and these had results similar to earlier work done by others in human cadavers. High pressure results demonstrating movement of fluid through the arachnoid granules were deemed correct. Because of Cushing's position of authority, the theory became accepted as fact and in time proved to be entrenched dogma. Walter Dandy demonstrated in experiments on hydrocephalus and the surgical removal of the arachnoid granule system that the fluid was produced by the choroid plexuses and not absorbed by the arachnoid granules. His work was dismissed by Weed as unreliable. Examination of the pattern of deposition of corpora amylacea on the surface of the brain provides evidence that cerebrospinal fluid does not pass through arachnoid granules but passes through the choroid fissure and is recycled through choroid plexus portals. The choroid plexus portal theory can explain the findings in the low-pressure experiments of Weed. Bias and pride seem to be the source of the faulty theory. Entrenched dogma is resistant to challenge.

The studies showed tow tendencies of the haemodynamic changes: regional hypertonicity and hypotonicity. The specificity of the haemodynamic factors depends on the phase of the hypertensive syndrome and the duration of the disease.

    2007-05-01

    Multiple spinal extradural meningeal cysts are rare. To the authors' knowledge, there have been only four reported cases in the world literature. The authors report a case of multiple spinal extradural meningeal cysts in a 31-year-old woman presenting with acute paraplegia. Magnetic resonance imaging of the thoracolumbar spine revealed multiple extradural cystic lesions extending from T-7 to T-8 and from T-12 to L-3. Intraoperative findings demonstrated a white, fibrous, and tense cyst filled with cerebrospinal fluid-like colorless fluid. Excision of the posterior wall of the symptomatic cyst was followed by immediate neurological improvement. The examination of the pathological specimen showed a thick duralike layer of collagen and an inner membrane of arachnoid that is often not found in these lesions. The final diagnosis was based on combined imaging, intraoperative, and histopathological findings. The authors review the literature and discuss the etiological, diagnostic, and therapeutic aspects of this lesion.

The animals were divided into four groups: in Group 1, eight animals received traumatic injury only; in Group 2, 12 animals received traumatic injury following injection of 100 mg kaolin suspended in 1 cc normal saline solution into the subarachnoid space at the site of trauma; in Group 3, nine animals received traumatic injury following injection of 200 mg kaolin in 1 cc normal saline solution into the subarachnoid space at the site of trauma; and in Group 4, nine animals without traumatic injury received an injection of 200 mg kaolin in 1 cc normal saline solution into the subarachnoid space. The subjective criteria for syrinx formation were the presence of a definite round cyst having a smooth margin and an upper or lower extension of more than 2 cm from the injured site. Syrinx formation was seen in 12.5% (one of eight rabbits) in Group 1, 41.7% (five of 12 animals) in Group 2, 55.5% (five of nine rabbits) in Group 3 and 0% (none of nine animals) in Group 4 (p duration of survival, was also statistically significant. In summary, subarachnoid block secondary to adhesive arachnoiditis is important in initiating the extension of the syringomyelia cavity.

    Full Text Available The case of a 24-year-old man with progressive visual loss due to optochiasmatic arachnoiditis is presented. The cause of the arachnoiditis was subarachnoidal bleeding due to rupture of an internal carotid artery aneurysm. The aneurysm was clipped 5 years after the first episode of bleeding. The diagnosis of optochiasmatic arachnoiditis was confirmed during the operation. This case, is presented in order to discuss the causes, the symptoms and the therapeutical possibilities of this rare condition.

    A rapidly progressive neurotrophic arthropathy of the shoulder was noted in a 44-year-old man with tuberculous adhesive arachnoiditis. Difficulty in making the diagnosis of adhesive arachnoiditis was encountered because of the variable and confusing neurologic manifestations until a cisternal myelogram was performed and this previously unreported relationship established.

    Full Text Available Intradural extra-arachnoid lumbar disc herniation is a rare disease. Few MRI findings have been reported. We experienced an intradural extra-arachnoid lumbar disc herniation. We reviewed the preoperative MRI findings. Lumbar spine T2-weighted sagittal MRI showed that one line of the ventral dura was divided into two by a disc herniation. We speculated that the two lines comprised the dura and arachnoid and that a disc herniation existed between them. We believe that division of the ventral dural line on T2-weighted sagittal images is a characteristic finding of intradural extra-arachnoid lumbar disc herniation. The division of ventral dural line seemed to be a “Y,” and, thus, we called it the “Y sign.” The “Y sign” may be useful for diagnosing intradural extra-arachnoid lumbar disc herniation.

    Magnetic resonance sequences may be designed to evaluate the diffusion movements of the protons (diffusion-weighted images, DWI). In these images, a bright signal identifies a region where the diffusion along a spatial axis is restricted. The contents of a cystic lesion frequently have the signal intensities of a generic homogeneous hyperproteinic fluid (hypointensity in T1-, hyperintensity in T2-weighted images). DWI may give further information about the microscopic organisation of these fluids: a hyperintense signal indicates the presence of a restricted diffusion, due to some kind of microscopic organisation, at the cellular or macromolecular level. This may provide additional information useful for clinical purposes. We obtained DWI in 24 consecutive patients with intracranial cystic lesions, (19 intra-axial: five abscesses, five gliomas, six metastases, two demyelinating lesions, one neurocysticercosis; five extra-axial: two arachnoid cysts, two epidermoid cysts, one cholesteatoma). We found a strongly hyperintense signal, indicating restricted diffusion, in brain abscesses, epidermoid cysts and cholesteatoma; all the remaining lesions were hypointense or mildly hyperintense. We found these data useful in critical diagnoses, such as in differentiating abscesses from tumours, and in identifying elusive tumours such as epidermoid cysts. (orig.)

    Pineal cysts, both simple and complex, are commonly encountered in children. More cysts are being detected with MR technology; however, nearly all pineal cysts are benign and require no follow-up. To discover the prevalence of pineal cysts in children at our institution who have undergone high-resolution 3-T MRI. We retrospectively reviewed 100 consecutive 3-T brain MRIs in children ages 1 month to 17 years (mean 6.8 {+-} 5.1 years). We evaluated 3-D volumetric T1-W imaging, axial T2-W imaging, axial T2-W FLAIR (fluid attenuated inversion recovery) and coronal STIR (short tau inversion recovery) sequences. Pineal parenchymal and cyst volumes were measured in three planes. Cysts were analyzed for the presence and degree of complexity. Pineal cysts were present in 57% of children, with a mean maximum linear dimension of 4.2 mm (range 1.5-16 mm). Of these cysts, 24.6% showed thin septations or fluid levels reflecting complexity. None of the cysts demonstrated complete T2/FLAIR signal suppression. No cyst wall thickening or nodularity was present. There was no significant difference between the ages of children with and without cysts. Cysts were more commonly encountered in girls than boys (67% vs. 52%; P = 0.043). There was a slight trend toward increasing pineal gland volume with age. Pineal cysts are often present in children and can be incidentally detected by 3-T MRI. Characteristic-appearing pineal cysts in children are benign, incidental findings, for which follow-up is not required if there are no referable symptoms or excessive size. (orig.)

    Aims: To analyse the clinical presentation, clinicopathological correlation and management of complex ovarian cysts in newborn and infants. Materials and Methods: Over a period of 6 years (2009-2015), 25 newborns who were diagnosed to have ovarian cyst on antenatal ultrasound, were followed up. We collected data in the form of clinical features, radiological findings, pathology and mode of treatment. Results: Of the 25 fetuses who were diagnosed to have ovarian cysts, fourteen (56%) underwent spontaneous regression by 6-8 months. Eight were operated in newborn period while 3 were operated in early infancy. Seven had ovarian cyst on right side, 4 had on left side. Eight babies underwent laparoscopy while 3 underwent laparotomy. Histopathology showed varied features of hemorrhagic cyst with necrosis and calcification, serous cystadenoma with hemorrhage, benign serous cyst with hemorrhage and simple serous cyst. Post-operative recovery was uneventful in all. Conclusion: All the ovarian cysts detected antenatally in female fetuses need close follow-up after birth. Since spontaneous regression is known, only complex or larger cysts need surgical intervention, preferably by laparoscopy. Majority of the complex cysts show atrophic ovarian tissue hence end up in oophorectomy but simple cysts can be removed preserving normal ovarian tissue whenever possible. PMID:28083489

    Post laminectomy arachnoiditis has been shown by experiments with rats and post operative radiological imaging in humans. The purpose of this experimental study was to determine the efficacy of tenoxicam in preventing arachnoiditis in rats. Twenty-four Wistar rats were divided into two groups, and L3 laminectomy was performed. In the tenoxicam group, 0.5 mg/kg tenoxicam was applied intraperitoneally. Normal saline was applied intraperitoneally in the control group. Later, the rats were killed at weeks 3 and 6, and the laminectomy sites were evaluated pathologically for arachnoiditis. The results showed that 6 weeks after surgery, the tenoxicam group showed lowest arachnoiditis grades. However, statistically significant difference was not found in arachnoiditis between the control group and the tenoxicam group. Based on these findings it is concluded that application of the tenoxicam after lumbar laminectomy did not effectively reduce arachnoiditis. Performing the most effective surgical technique without damage around tissue in a small surgical wound and having meticulous hemostasis in surgery seem to be the key for preventing arachnoiditis effectively.

    Full Text Available A 21-year-old male with developmental delay presented with abdominal pain of two days' duration. He was afebrile and his abdomen was soft with mild diffuse tenderness. There were no peritoneal signs. Plain x-ray demonstrated a large air-filled structure in the right upper quadrant. Computed tomography of the abdomen revealed a 9×8 cm structure adjacent to the hepatic flexure containing an air-fluid level. It did not contain oral contrast and had no apparent communication with the colon. At operation, the cystic lesion was identified as a duplication cyst of the sigmoid colon that was adherent to the right upper quadrant. The cyst was excised with a segment of the sigmoid colon and a stapled colo-colostomy was performed. Recovery was uneventful. Final pathology was consistent with a duplication cyst of the sigmoid colon. The cyst was attached to the colon but did not communicate with the lumen.

    Retrorectal, developmental tail gut cysts, include dermoid cysts, rectal duplication cysts and retrorectal cyst-hamartomas. Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hind gut, which normally involutes by the 8th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and teratomas). We report a patient with adenosquamous carcinoma arising within RCH, who underwent complete resection of the cyst through anterior laparotomy, and reached complete (recurrencefree for 14 mo, so far) functional recovery. The cyst was incidentally discovered during hysterectomy 12 years ago.Diagnostic, therapeutic and histopathological aspects of this rare case are discussed. The mentioned period between diagnosis and surgical treatment suggests that RCH, given enough time, can develop malignant degeneration, and should be resected at the time of diagnosis.

    We present a patient who developed a high central neural block after stellate-ganglion-blockade. The underlying pathophysiology was assessed via sonographic imaging. Stellate ganglion block was performed in a 19-year old patient according to the standard technique. Multiple aspiration tests were negative and a test dose of 3 ml bupivacaine 0.25% was injected. After a 3 min interval another 5 ml were injected. Two minutes after the local anaesthetic administration the patient reported nausea and sensations in the upper extremity. Spontaneous respiration efforts stopped, and the patient became unconscious. Tracheal intubation was performed, and the patient was ventilated in a controlled mode for two hours. Heart rate as well as blood pressure remained within the normal range. Neurologic recovery occurred rapidly and extubation was performed about two and a half hours after the event. Our sonographic studies demonstrated a local anaesthetic depot directly at the root of C 6, with a mean diameter of 10 mm and a length of 5 to 6 cm (about a third smaller than expected). Sonographic studies and clinical symptoms of our patient are most likely to occur with a subdural extra-arachnoidal block. Ultrasonographic guided puncture enhances the patient's safety by the opportunity to directly visualise transverse process, nerval root as well as local anaesthetic depot. In case of depot formation directly at the nerval root, injection may be stopped and the needle repositioned. Furthermore, direct visualisation of the great vessels (A. vertebralis) prevents intravascular injection and haematoma formation.

    The objective of the case series is to understand the clinical and surgical aspects of new minimally invasive technique of coblation in cases of vallecular cysts in neonates. Method of Study. Four neonates underwent surgery for vallecular cyst by using Arthrocare ENT coblator system. Results Obtained. All the four cases presented in stridor and difficult intubation was also a concern which necessitated a swift, high precision instrument with almost immediate results. Coblation excision includes direct contact with vallecular cyst, improved targeting of the cyst, and preservation of normal tissue. All the four cases had an uneventful postoperative period and smooth recovery and had an early discharge from the hospital. Conclusions. Early diagnosis and intervention hold the key for an early recovery and for minimizing nutritional disturbances secondary to poor feeding in cases of neonatal vallecular cysts. PMID:25405048

    Proliferative granulomatous arachnoiditis is an infrequent manifestation of central nervous system tuberculosis. The mortality rate is 30%, and there are functional sequels in almost all patients. We present the case of a 22-year-old woman, immunocompetent that suffered form tuberculous radiculo-myelopathy with fatal evolution, which allowed us to confront neuroimaging and neuropathological findings. Although serial MR imaging illustrated evolution of lesions, autopsy revealed more extensive lesions that those observed in neuroimaging studies. The characteristic pathological lesion was an intradural inflammatory exudate with a global medullar necrosis. Even through duration of medical treatment is still discussed, early diagnosis, complete antituberculous drug regimen and prolonged corticosteroid therapy are essential to avoid fatal evolution as occurred in this case.

    Full Text Available In a certain group of patients with syringomyelia, even with the advent of sophisticated magnetic resonance imaging (MRI, no associated abnormality or cerebrospinal fluid (CSF block is easily identified. This type of syringomyelia is often termed idiopathic. Current literature has less than 10 reports of arachnoid webs to be the causative factor. We present our experience in the management of two cases of syringomyelia secondary to arachnoid webs. Both our patients presented with progressive neurological deterioration with MRI scans demonstrating cervical/thoracic syrinx without Chiari malformation or low-lying cord. There was no history of previous meningitis or trauma. Both patients underwent myelography that demonstrated dorsal flow block implying CSF obstruction. Cord displacement/change in caliber was also noted and this was not evident on MRI scans. Both patients underwent thoracic laminectomy. After opening the dura, thickened/abnormal arachnoid tissue was found that was resected thus widely communicating the dorsal subarachnoid space. Postoperatively at 6 months, both patients had significant symptomatic improvement with follow-up MRI scans demonstrating significant resolution of the syrinx. In patients with presumed idiopathic syringomyelia, imaging studies should be closely inspected for the presence of a transverse arachnoid web. We believe that all patients with idiopathic symptomatic syringomyelia should have MRI CSF flow studies and/or computed tomography (CT myelography to identify such arachnoid abnormalities that are often underdiagnosed. Subsequent surgery should be directed at the establishment of normal CSF flow by laminectomy and excision of the offending arachnoid tissue.

  11. Baker’s Cyst

    Science.gov (United States)

    Frush, Todd J.; Noyes, Frank R.

    2015-01-01

    Context: Popliteal synovial cysts, also known as Baker’s cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they are not seen in the knee joint. Baker’s cysts can be a source of posterior knee pain that persists despite surgical treatment of the intra-articular lesion, and they are routinely discovered on magnetic resonance imaging scans of the symptomatic knee. Symptoms related to a popliteal cyst origin are infrequent and may be related to size. Evidence Acquisition: A PubMed search was conducted with keywords related to the history, diagnosis, and treatment of Baker’s cysts—namely, Baker’s cyst, popliteal cyst, diagnosis, treatment, formation of popliteal cyst, surgical indications, and complications. Bibliographies from these references were also reviewed to identify related and pertinent literature. Study Design: Clinical review. Level of Evidence: Level 4. Results: Baker’s cysts are commonly found associated with intra-articular knee disorders. Proper diagnosis, examination, and treatment are paramount in alleviating the pain and discomfort associated with Baker’s cysts. Conclusion: A capsular opening to the semimembranosus–medial head gastrocnemius bursa is a commonly found normal anatomic variant. It is thought that this can lead to the formation of a popliteal cyst in the presence of chronic knee effusions as a result of intra-articular pathology. Management of symptomatic popliteal cysts is conservative. The intra-articular pathology should be first addressed by arthroscopy. If surgical excision later becomes necessary, a limited posteromedial approach is often employed. Other treatments, such as arthroscopic debridement and closure of the valvular mechanism

    Full Text Available A bronchogenic cyst is a rare congenital anomaly that appears in the thorax, usually the lungs or the mediastinum, being much rarer in the retrosternal space, within the pericardium or the diaphragm, as well as in the neck, while localization within the abdomen is extremely rare, with only about 30 reported cases. We present the case of a 68-year-old woman. During an investigation for an epigastric pain, a cystic lesion in the area of the body and tail of the pancreas was found. During open surgery, a cystic lesion, spanning 95x75x70 mm, above the body and tail of the pancreas was excised. The wall of the cyst was 8-12mm thick; it contained viscous fluid, the culture of which stayed sterile. Histology determined that it was a bronchogenic cyst. After an early uneventful recovery, the patient developed a left colonic fistula, which healed spontaneously within 3 weeks, probably because of the unnoticed operative damage to the splenic flexure of the colon during splenectomy, which was adherent to the cystic mass and impossible to save during excision. Six months after surgery, the patient continued to remain symptom free.

There was associated difficulty in speech and mastication as the swelling increased in size. Intraoral examination revealed moderately tender, fluctuant and enlarged tongue. A diagnosis of dermoid cyst was made and the patient was booked for surgery. Excision of the cyst was done under general anaesthesia. Post-operative histopathology was done. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (I a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (II connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence. Keywords: dermoid; epidermoid cyst;tounge. | PubMed

    Full Text Available Bronchogenic cysts occur due to the anomalous development of the primitive tracheobronchial tree early in fetal life. They are usually present in middle mediastinum. Rarely, they have been found in other locations. We describe two patients with subcutaneous bronchogenic cysts located over manubrium sterni with special emphasis on the difficulties in pre-operative diagnosis. The two boys were managed by complete excision of the cysts. The children are well on follow-up.

    A 39-year-old woman was admitted to hospital with headaches, vomiting, psychic impairment and diplopia. Three hydatid cysts of the lung had been previously removed. An avascular mass in the left hemisphere with left-to-right displacement of the anterior cerebral arteries was noted during a brain angioscintigraphy. A cerebralthrombosis (CT) brain scan showed two cystic lesions situated in the left-frontal and occipital regions. A CT abdominal scan showed multiple cysts in the liver, spleen and both kidneys. At operation, two brain cysts were totally extirpated without rupture. The definite pathological diagnosis was secondry hydatid cysts. The headaches, vomiting and diplopia were persistent in the post-operative period. Seven days after the operation, a CT brain scan showed an infratenrorial cyst. The patient rejected any surgical intervention.

    Thymic cysts are rare lesions of the anterior mediastinum or neck. The majority are asymptomatic, and the remainder are associated mainly with symptoms of dysphagia or dyspnea. Diagnosis is difficult before surgery. Cervical thymic cysts are relatively rare; age at presentation ranges from the neonatal period to adulthood, and the most frequent presenting sign is a lateral neck mass. Mediastinal thymic cysts are more common and account for 1% of all mediastinal masses. They tend to occur in the older age group and are usually detected incidentally on chest X-ray film or computed tomography scans. Dysphagia and dyspnea are the main symptoms. We describe two brothers, aged 5 and 8 years, with mediastinal thymic cysts that presented as low cervical masses and review the embryology, diagnosis and management of thymic cysts.

    2011-01-01

    Full Text Available Tuberculous spinal arachnoiditis involving cauda equina is rare. A patient with lumbar tuberculous arachnoiditis in the absence of both vertebral and meningeal tuberculosis, which was mimicking spinal intradural extramedullary tumor is described here. Diagnosis was made based on intraoperative findings and was confirmed by histopathology. Surgical decompression along with a combination of steroid and antitubercular therapy resulted in a good outcome. At 3 months follow-up, the patient regained bladder control and was able to walk with support. Clinical features, magnetic resonance imaging, and intraoperative findings are described. Pathology and the relevant literature are discussed. Based on the patient′s clinical and radiologic findings, it was believed that the patient had a conus cauda tumor and was operated on. Histologic examination of the mass revealed tuberculoma. Surgical decompression followed by antituberculosis medication resulted in good outcome. Hence tuberculous arachnoiditis should be considered in differential diagnosis of conus cauda tumors.

    Most neurosurgical procedures could be performed noninvasively by working through the natural corridors provided by the subarachnoid cisterns. In consequence, the subarachnoid cisterns have been considered as the roadmaps for the microneurosurgeons. The concept and the contents of the cisterns have been well known and described, but the knowledge of the detailed anatomy of the arachnoid membranes, which are the real septa of the cisterns and provide the practical and important landmarks and planes for the dissections during the brain surgeries, is still lacking. The present article reviews the previous reports of the intracranial arachnoid membranes with a special emphasis on the microsurgical anatomy and the clinical significance.

    Full Text Available A 14-year-old boy underwent emergency debridement surgery of right foot under spinal anaesthesia. Four hours after the surgery, the patient developed symptoms of cauda equina syndrome (CES. Postoperative magnetic resonance imaging of the patient′s spine suggested underlying tubercular arachnoiditis. The boy was started on intravenous methylprednisolone and antitubercular therapy. He responded to the therapy and recovered completely in 2 weeks without any residual neurological deficits. We suggest that underlying pathological changes in the subarachnoid space due to tubercular arachnoiditis contributed to maldistribution of the local anaesthetic drug leading to CES.

    2009-01-01

    Tarlov cysts or spinal perineurial cysts are uncommon lesions. These are mostly incidental findings on magnetic resonance imaging or myelograms. The objectives of this study were to describe Tarlov cysts of the sacral region as a potential cause for retrograde ejaculations and review available management options. Case report and literature review. A 28-year-old man presented with back pain and retrograde ejaculations resulting in infertility. After microsurgical excision of large perineurial cysts, back pain resolved, but semen quality showed only marginal improvement. Later, the couple successfully conceived by intrauterine insemination. To the best of our knowledge, this is the first reported case of Tarlov cyst associated with retrograde ejaculation and infertility. Despite being mostly asymptomatic and an incidental finding, Tarlov cyst is an important clinical entity because of its tendency to increase in size with time. Tarlov cysts of the sacral and cauda equina region may be a rare underlying cause in otherwise unexplained retrograde ejaculations and infertility. Microsurgical excision may be a good option in a select group of patients.

    A 66-year-old woman, having no complaint, admitted our clinic, because of a mass in the right superior mediastinum detected three years ago on chest X-ray. The operation was performed through the right thoracotomy in December of 1989. The thin-walled cyst located adjacent to the trachea between superior vena cava and back bones, occupied from beneath the innominate artery to the right main bronchus. The tumor (7 x 5 x 5 cm) weighing 80 grams had a smooth surface and contained watery fluid. Histological examination showed a cyst lined a monolayer of cuboidal epithelium. The cyst wall consisted of parathyroid tissue. Mediastinal parathyroid cyst is very rare. Since the first report of DeQuervain, 15 cases have been reported. These reports are reviewed.

    Full Text Available Simple bone cysts (SBC are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid. In jaws initially it mimics a periapical cyst and later can lead to cortical bone expansion warranting for radical approach, which is seldom required. SBC is predominantly diagnosed in first two decades of life. Here we report a case of solitary bone cyst mimicking a periapical cyst of a mandibular molar in a 37-year-old patient.

    Background and Objectives: Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure. Methods: A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively. Results: Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate. Conclusion: When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

    Dmitriev, Konstantin; Gutenko, Ievgeniia; Nadeem, Saad; Kaufman, Arie

    2016-03-01

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

  19. Focal adhesive arachnoiditis of the spinal cord: Imaging diagnosis and surgical resolution

    Directory of Open Access Journals (Sweden)

    Hiroki Morisako

    2010-01-01

    Full Text Available Background: Although adhesive arachnoiditis of the spinal cord can cause progressive symptoms associated with syringomyelia or myelomalacia, its surgical resolution based on the imaging diagnosis is not well characterized. This study aims to describe the use of imaging for the diagnosis of focal adhesive arachnoiditis of the spinal cord and its surgical resolution using microsurgical arachnoidolysis. Materials and Methods: Four consecutive patients with symptomatic syringomyelia or myelomalacia caused by focal adhesive arachnoiditis underwent microsurgical arachnoidolysis. Comprehensive imaging evaluation using constructive interference in steady-state (CISS magnetic resonance imaging (MRI or myelographic MR imaging using true fast imaging with steady-state precession (TrueFISP sequences was included before surgery to determine the surgical indication. Results: In all four patients a focal adhesion was identified at the cervical or thoracic level of the spinal cord, a consequence of infection or trauma. Three patients showed modest or minor improvement in neurological function, and one patient was unchanged after surgery. The syringomyelia or myelomalacia resolved after surgery and no recurrence was noted within the follow-up period, which ranged from 5 months to 30 months. Conclusions: MRI diagnosis of focal adhesive arachnoiditis is critical to determine the surgical indication. Microsurgical arachnoidolysis appears to be a straightforward method for stabilizing the progressive symptoms, though the procedure is technically demanding.

    Spinal hydatid cysts account for 1% of all cases of hydatid disease; primary intradural hydatid cysts are uncommon. We present a case of pathologically confirmed intradural spinal cyst hydatid in an otherwise healthy patient who showed no other evidence of systemic hydatid cyst disease. The patient presented with back pain, paraparesis, and weakness. An intradural extramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be a hydatid cyst by histopathologic examination after surgical removal. To our knowledge, this is the 25th case of hydatid cyst at an intradural extramedullary location reported in the literature.

  2. Bone cysts: unicameral and aneurysmal bone cyst.

    Science.gov (United States)

    Mascard, E; Gomez-Brouchet, A; Lambot, K

    2015-02-01

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy.

    Full Text Available Gliomas are the most common infiltrative neoplasms of the optic nerve and can present as two distinct growth patterns: intraneural glial proliferation and perineural arachnoidal gliomatosis (PAG. It has been suggested that perineural arachnoidal gliomatosis is seen almost exclusively in the setting of neurofibromatosis type 1 (NF1. We describe a child with perineural arachnoidal gliomatosis occurring without neurofibromatosis type 1, supported by both radiographic and histological findings. A 4-year-old female without neurofibromatosis type 1 presented with rapidly progressive right-sided proptosis. Magnetic resonance imaging (MRI revealed an enhancing fusiform intraconal lesion, which was hypointense on T1 and hyperintense on T2-weighted images: characteristic of perineural arachnoidal gliomatosis, the optic nerve was visualized coursing the tumor. Histopathologic study was consistent with perineural arachnoidal gliomatosis. Perineural arachnoidal gliomatosis can develop independent of neurofibromatosis type 1, as demonstrated by this case.Gliomas são as neoplasias infiltrativas mais freqüentes do nervo óptico e podem se apresentar através de dois padrões distintos de crescimento: proliferação glial intraneural e gliomatose aracnoidal perineural.

    Full Text Available Abstract Background The arachnoid granulations (AGs are projections of the arachnoid membrane into the dural venous sinuses. They function, along with the extracranial lymphatics, to circulate the cerebrospinal fluid (CSF to the systemic venous circulation. Disruption of normal CSF dynamics may result in increased intracranial pressures causing many problems including headaches and visual loss, as in idiopathic intracranial hypertension and hydrocephalus. To study the role of AGs in CSF egress, we have grown cells from human AG tissue in vitro and have characterized their expression of those cytoskeletal and junctional proteins that may function in the regulation of CSF outflow. Methods Human AG tissue was obtained at autopsy, and explanted to cell culture dishes coated with fibronectin. Typically, cells migrated from the explanted tissue after 7–10 days in vitro. Second or third passage cells were seeded onto fibronectin-coated coverslips at confluent densities and grown to confluency for 7–10 days. Arachnoidal cells were tested using immunocytochemical methods for the expression of several common cytoskeletal and junctional proteins. Second and third passage cultures were also labeled with the common endothelial markers CD-31 or VE-cadherin (CD144 and their expression was quantified using flow cytometry analysis. Results Confluent cultures of arachnoidal cells expressed the intermediate filament protein vimentin. Cytokeratin intermediate filaments were expressed variably in a subpopulation of cells. The cultures also expressed the junctional proteins connexin43, desmoplakin 1 and 2, E-cadherin, and zonula occludens-1. Flow cytometry analysis indicated that second and third passage cultures failed to express the endothelial cell markers CD31 or VE-cadherin in significant quantities, thereby showing that these cultures did not consist of endothelial cells from the venous sinus wall. Conclusion To our knowledge, this is the first report of

    The purpose of this study was to determine the incidence of meniscal cysts, assess the frequency of various magnetic resonance (MR) imaging characteristics, and emphasize radiographic observations not commonly reported. A total of 2,095 consecutive knee MR imaging reports from a 22 month period were retrospectively reviewed for the presence of meniscal cysts. Two musculoskeletal radiologists reviewed the cases where cysts were reported. A meniscal cyst was considered present if abnormally increased signal was identified within an enlarged meniscus (i.e., intrameniscal cyst) or if a loculated fluid-intensity lesion with a clear connection to the adjacent meniscus was identified (i.e., parameniscal cyst). Presence or absence of a meniscal tear, intrameniscal and parameniscal signal intensity, patient age, sex, location of meniscal cyst, presence of discoid meniscus, and size of the parameniscal cyst component were recorded. All knee imaging examinations were performed on a 1.5T MR unit. Imaging findings were correlated with arthroscopic reports when available. A total of 167 cases (8.0%) of meniscal cysts were diagnosed in 161 patients. Of the 167 cysts, 69 (41.3%) were located in the lateral meniscus and 98 (58.7%) in the medial meniscus. In 6 patients (3.7%), meniscal cysts were present in both menisci of the same knee. Twelve (7.2%) meniscal cysts were associated with discoid menisci. Ninety-seven (57.8%) meniscal cysts were associated with meniscal tears. Of the total number of meniscal cysts, 104 (62.3%) had a parameniscal cyst. An isolated intrameniscal cyst was present in 63 (37.7%) cases. One hundred (96%) of the parameniscal cyst components were isointense to fluid on T2-weighted FSE images. All cysts exhibited abnormal intrameniscal signal. Only 14 (8.4%) of the intrameniscal components were isointense to fluid on T2-weighted FSE images. The arthroscopic reports of 88 of the 161 (54.7%) patients were available for review and correlation. A tear extending to

    2003-07-01

    Full Text Available We describe the magnetic resonance imaging (MRI signal characteristics of isolated (solitary lesion intra fourth ventricular cysticercus cyst in 4 patients who clinically presented with obstructive hydrocephalus. All patients had routine MRI sequences (T1, T2, & proton density-weighted imaging, Fluid Attenuation Inversion Recovery (FLAIR, and post-gadolinium imaging followed by cerebrospinal fluid (CSF flow study. It revealed a CSF signal intensity (on all pulse sequences, intra fourth ventricular cyst with a nidus (scolex, and wall enhancement. On T1-weighted and FLAIR images, the cyst wall and nidus (scolex were seen in 3 cases, which were not seen in other routine sequences. The CSF flow study showed the intraluminal nature of the cyst. The MRI features suspected a cysticercus cyst, and per-operative findings and histopathological examination confirmed the diagnosis. The review of literature of the intra fourth ventricular cyst is briefly discussed.

    Sacral perineurial (Tarlov) cysts are rare lesions. Over a seven year period 4000 patients underwent surgery for lumbar disk herniation. In three patients neurological symptoms were caused by large sacral perineurial cysts. Methods of choice for diagnosis of Tarlov cysts are lumbosacral magnetic resonance imaging and computerized tomography myelography. The majority of Tarlov cysts are asymptomatic. In case of large (> or = 1.5 cm) and symptomatic perineurial cyst, as in three patients reported in this article, microsurgical treatment was successful. Although rare, perineurial (Tarlov) cysts must be taken into consideration when approaching to patient with low back and radicular pain. Authors review the medical literature, pathological and pathophysiological features and treatment options of sacral perineurial cysts.

    Full Text Available The calcifying odontogenic cyst (COC is reported to be associated with odontoma in 24% of cases. Separation of the cases of calcifying odontogenic cyst associated with odontoma (COCaO may lead to a better understanding of the pathogenesis of this lesion. The literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. Most common location was the maxilla (61.5%. The radiographic appearance of most cases (80.5% was a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions consisted of a single large cyst with tooth-like structures as an integral part, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested.

    Lumbar epiduro-arachnoiditis is a well-known complication of surgery of the intervertebral disc. The epidural fibrous scar is the normal outcome of inflammatory activity secondary to the mechanical tissue disturbance resulting from surgery. In certain individuals, perhaps genetically predisposed as excessive quantity of fibrous tissue is deposited in the epi and/or nitradural space. This abnormal situation, comparable to cheloid cutaneous scars, is perhaps at the origin of the clinical symptoms. The authors report the clinical and radiological signs observed in 38 patients having had at least one operation for discal hernia, and who underwent further operations in the aim of freeing the roots and the dural sack from fibrous compression. Results of excision of the epidural "cheloid" were good in 13 cases, and average in 8 others. There was a complete failure in 17 other patients. Three explanations were offered to explain the frequency of the failures: 1) formation of a new cheloid, 2) difficulty of neurolysis of the arachnoiditis, 3) possibility of intrinsic lesions of the nerve associated with the epiduro-arachnoiditis.

    Cryptococcus can cause meningoencephalitis (CM) among previously healthy non-HIV adults. Spinal arachnoiditis is under-recognized, since diagnosis is difficult with concomitant central nervous system (CNS) pathology. We describe 6 cases of spinal arachnoiditis among 26 consecutively recruited CM patients with normal CD4 counts who achieved microbiologic control. We performed detailed neurological exams, cerebrospinal fluid (CSF) immunophenotyping and biomarker analysis before and after adjunctive immunomodulatory intervention with high dose pulse corticosteroids, affording causal inference into pathophysiology. All 6 exhibited severe lower motor neuron involvement in addition to cognitive changes and gait disturbances from meningoencephalitis. Spinal involvement was associated with asymmetric weakness and urinary retention. Diagnostic specificity was improved by MRI imaging which demonstrated lumbar spinal nerve root enhancement and clumping or lesions. Despite negative fungal cultures, CSF inflammatory biomarkers, sCD27 and sCD21, as well as the neuronal damage biomarker, neurofilament light chain (NFL), were elevated compared to healthy donor (HD) controls. Elevations in these biomarkers were associated with clinical symptoms and showed improvement with adjunctive high dose pulse corticosteroids. These data suggest that a post-infectious spinal arachnoiditis is an important complication of CM in previously healthy individuals, requiring heightened clinician awareness. Despite microbiological control, this syndrome causes significant pathology likely due to increased inflammation and may be amenable to suppressive therapeutics.

    Hydrocephalus is the abnormal accumulation of cerebrospinal fluid (CSF) within the confines of the skull that if left untreated results in significant morbidity and mortality. The treatment for hydrocephalus has remained essentially unchanged for over 50 years. It was a technological advance in materials that allowed John Holter, in conjunction with neurosurgeons Spitzer and Nulsen, to devise a valve and shunt system that diverted excess CSF from the ventricular space to the peritoneum. This ventriculo-peritoneal (VP) shunt is far from ideal, with problems associated with under/over shunting, mechanical mismatch, infection, high failure rates, disconnection and erosion. With the advances in the field of micro-fabrication and micro-machines we propose an innovative shunt system that would mimic the function of arachnoid granulations. This micro-fabricated shunting device, or micro-mechanical arachnoid granulation (MAG), consists of a multiplicity of micro-valves each 210 μm in diameter that each adhere to individual micro-needles. This work demonstrates the design and initial test results of the micro-valve with parameters for low cracking pressure, optimal flow rate, and reflux that would mimic the function of the native arachnoid granulations.

    Spinal synovial cysts are a known cause of back pain and radiculopathy. With the advent of high-resolution imaging techniques, synovial cysts are increasingly diagnosed. There are a variety of treatment options for these lesions. A systematic literature review of published articles reporting outcomes after nonsurgical and surgical management of spinal synovial cysts was performed. There were 51 published studies regarding the treatment of synovial cysts identified. Treatment modalities include observation, steroid injections, percutaneous cyst aspiration, hemilaminectomy or bilateral laminectomy with and without instrumented fusion, and minimally invasive cyst excision. Based on review of the treatment modalities and outcomes, recommendations for the management of patients with synovial cysts are proposed. Observation can be considered in cases where there is no intractable pain. High-risk surgical patients with intractable pain may consider corticosteroid injection or percutaneous cyst aspiration; however, the failure rate of such a procedure approaches 50%. Patients with intractable pain are candidates for surgical resection of the symptomatic cyst. In cases of significant neurologic deficit, motor weakness, back pain, multiple synovial cysts, or spondylolisthesis, bilateral laminectomy and instrumented fusion may offer the best long-term outcome.

    Full Text Available Context Pseudocysts are a common complication of acute and chronic pancreatitis. These are usually located within the pancreas but they can occur at other sites as well, including the mediastinum, neck, pelvis and rarely in the liver as in our case. The diagnosis of intrahepatic pancreatic pseudocyst relies on the demonstration of a high amylase level in the sampled cystic fluid in the absence of infection or neoplasm. Case report A 60-year-old man with a history of chronic pancreatitis presents with a clinical and laboratory picture suggestive of acute exacerbation of his pancreatitis. A computed tomogram (CT scan of the abdomen revealed a pancreatic pseudocyst and a cystic lesion involving both lobes of the liver. CT diagnostic aspiration of the intrahepatic cyst revealed high amylase level (greater than 20,000 U/L. The cyst was treated with percutaneous drainage with complete resolution of the cyst. Conclusion In the setting of pancreatitis, intrahepatic pancreatic pseudocyst should be considered in the differential diagnosis of cystic lesion of the liver.

    Full Text Available Syringomyelia resulting from arachnoiditis secondary to aneurysmal subarachnoid hemorrhage (SAH is an extremely rare clinical entity with few cases reported in the literature. The presentation, management, and pathogenesis of syringomyelia in this setting is poorly understood. We describe the presentation, radiology, management, and outcomes in two patients with syringomyelia resulting from arachnoiditis secondary to aneurysmal SAH and review the literature on this rare condition. Case number 1 was treated successfully with syrinx-subarachnoid shunt after extensive lysis of adhesions. Case number 2 was treated with syringoperitoneal shunt. Both patients had radiographic decreased syrinx size postoperatively. These patients add to the small literature on syringomyelia occurring secondary to SAH-associated arachnoiditis. The radiographic outcomes demonstrate that in the appropriately selected patient, syrinx-subarachnoid or syringoperitoneal shunting are viable options.

    2010-01-01

    Full Text Available Neurenteric cysts account for 0.7-1.3% of spinal axis tumors. These rare lesions result from the inappropriate partitioning of the embryonic notochordal plate and presumptive endoderm during the third week of human development. Heterotopic rests of epithelium reminiscent of gastrointestinal and respiratory tissue lead to eventual formation of compressive cystic lesions of the pediatric and adult spine. Histopathological analysis of neurenteric tissue reveals a highly characteristic structure of columnar or cuboidal epithelium with or without cilia and mucus globules. Patients with symptomatic neurenteric cysts typically present in the second and third decades of life with size-dependent myelopathic and/or radicular signs. Magnetic resonance imaging and computed tomography are essential diagnostic tools for the delineation of cyst form and overlying osseous architecture. A variety of approaches have been employed in the treatment of neurenteric cysts each with a goal of total surgical resection. Although long-term outcome analyses are limited, data available indicate that surgical intervention in the case of neurenteric cysts results in a high frequency of resolution of neurological deficit with minimal morbidity. However, recurrence rates as high as 37% have been reported with incomplete resection secondary to factors such as cyst adhesion to surrounding structure and unclear dissection planes. Here we present a systematic review of English language literature from January 1966 to December 2009 utilizing MEDLINE with the following search terminology: neurenteric cyst, enterogenous cyst, spinal cord tumor, spinal dysraphism, intraspinal cyst, intramedullary cyst, and intradural cyst. In addition, the references of publications returned from the MEDLINE search criteria were surveyed in order to examine other pertinent reports.

    We evaluated the diagnostic capability of MRI in ovarian chocolate cysts treated by Danazol (analogue of testosterone). Both inversion recovery as T1-weighted image and long TE and TR spin echo as T2-weighted image were performed before and during hormonal therapy. Temporal change of signal intensity and size was evaluated in three ovarian chocolate cysts (stage II: 2 cases, stage III: 1 case by Beecham classification, 1966) using the 0.15-T MR system. The high intense signal from all of the cysts was seen on both T1 and T2 weighted images before treatment. There was marked decrease in size of the chocolate cysts during hormonal therapy, and they were of considerably lower signal intensity than initially on T2-weighted image. We concluded that MRI was useful to evaluate hormonal therapy for ovarian chocolate cysts.

    The urachal cyst is a rare clinical entity of a urachal remnant. It is usually asymptomatic but can present with haematuria, tumour, urachal stone and infection. We present a case of a 63-year-old lady with a body mass index (BMI) of 49 who presented with a painful swelling in the umbilical region associated with an umbilical hernia. An ultrasound and computed tomography (CT) scan showed a suspected herniation of an umbilical remnant cyst through a paraumbilical defect. Laparoscopy confirmed the urachal cyst of 3 cm in size with a band connected with the cyst down to the urinary bladder associated with a 3-cm paraumbilical hernia. We removed the cyst and repaired the hernia laparoscopically uneventfully, after which her recovery was perfect. Radiological and laparoscopic pictures have not been reported in the English literature before. Although this condition is very rare, we suggest that it should be considered in the differential diagnosis of painful paraumbilical swelling. CT scanning and laparoscopy seems to be valuable, especially in obese patients.

    Full Text Available Hydatid disease is caused by the tapeworm Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis . Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease occurs either through direct ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%, followed by the lungs (18-35%. Bone hydatidosis however is very rare (3%. We present herein a case of hydatid cyst of the fibula, which is an uncommon site for the occurrence of this disease.

    Simple cysts are rare in the urinary bladder and can pose a diagnostic dilemma to both the urologist and the histopathologist. No case study was found in the database of Elsevier Science Direct, Spring-Link, or PubMed. We present two cases of subserous cyst in the bladder and discuss the diagnosis and treatment of the condition. The cystic lesion at bladder dome was detected by radiologic examination and confirmed by cystoscopy. In case 1, transurethral resection was first performed which was followed by partial cystectomy; In case 2, the cyst was removed with the urachus using laparoscopic surgery. The patients recovered uneventfully and the histopathology showed cysts in subserous layer of urinary bladder. The bladder cyst should be distinguished from urachal tumor, and laparoscopic partial cystectomy is the preferred operative procedure.

The inferior parathyroid glands are most commonly involved, with left-side predominance. Parathyroid cysts may be functional or nonfunctional, depending on their association with hypercalcemia. CASE REPORT: A 25-year-old man presented a palpable asymptomatic left-side neck mass. Ultrasound revealed a cystic structure contiguous with the left thyroid lobe. Serum ionic calcium was normal. The patient underwent left thyroid lobectomy plus isthmectomy with excision of the cyst. The histological findings revealed a parathyroid cyst.

    Full Text Available The paraurethral or Skene’s duct cyst, is a rare diagnostic entity in a newborn. It represents less than 0,5 % of congenital malformations of the urinary tract. All over the world it is reported an incidence of 1:2000 to 1:7000 in female births. In the newborn, the paraurethral cyst is caused by retention of secretions in the Skene's gland due to the obstruction of its ducts. Most of these cysts decrease in size during the first four to eight weeks, but they may cause symptoms of infection or urinary obstruction. They can also get formed from persistent embryonic remains of the mesonephric ducts (Wolffian duct, known as Gartner cysts and from the occlusion of unfused paramesonephric ducts (Müllerian. The case of a 25-day-old female, diagnosed with paraurethral cyst that underwent surgery and evolved successfully is presented.

    Background Echinococcosis is still endemic in many countries, including China, where it is especially prevalent in the northwest. The aim of this study was to enrich the international literature about the treatment of intracranial hydatid cysts.Methods We retrospectively reviewed the clinical features, radiological manifestations, and surgical outcome of 97 patients with intracranial hydatid cysts, who received surgical treatment at the Neurosurgical Department of First Affiliated Hospital of Xinjiang Medical University from 1985 to 2010 and followed up the patient via sending a questionnaire or telephone contact. Clinical outcome was evaluated using the Karnofsky Performance Scale Index.Results Headache and vomiting were the most common initial symptoms in our patients. Neurological deficits caused by the mass effect of the cysts were seen in 82 cases. On the X-ray, significant bone erosion was seen in only two cases with epidural hydatid cysts. Round-shaped and thin-walled homogeneous low-density cystic lesions without surrounding edema and enhancement were the main findings on computerized tomography (CT) in 95 patients with intraparenchymal hydatid cysts, while two cases with epidural hydatid cysts presented as a heterodensity lesions. On magnetic resonance imaging (MRI), hydatid cyst presented as a round-shaped low signal lesion in T1-weighted images and high signal lesion in T2-weighted images, without enhancement after contrast media injection, while the two cases with epidural cysts presented as mixed signal masses. Surgical removal of cyst was performed in all cases. Total removal was achieved in 93 cases without rupturing the cyst wall. Only two cysts ruptured during the dissection, resulting in two surgery-related mortalities. There was no other additional neurological deficit caused directly by surgery. In 97.2% of the patients, the Karnofsky Performance Scale score was 80 to 90 at the last follow-up.Conclusions Intracranial hydatid cyst is still a

    Epidermal cysts also known as epidermoid cysts, is one of the common benign tumours presenting anywhere in the body. However, epidermal cyst in the penis is very rare. This condition in children is usually congenital due to abnormal embryologic closure of the median raphe; hence, it is termed as median raphe cysts (MRCs). Penile epidermal cysts may occur in adults following trauma or surgery due to epidermal elements being trapped within closed space. During wound healing, trapped squamous epithelium, undergoing keratinisation leads to cyst formation. Here, we report a rare case of patient with a penile epidermoid cyst whose main complaints was discomfort during coitus. PMID:27437298

    A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month. There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing, lens removal with intraocular lens implantation. Slit lamp examination revealed a corneal scar at 9’oclock, a large transilluminant iris cyst superotemporally and adherent to corneal endothelium. It was extended from angle of the pupil and obstructing the visual axis. The patient underwent excision of an iris cyst through superior limbal incision. Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma. Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule. Post operatively 7 days, vision improved to 6/7.5 without complication. There was no recurrence up to 1 year postoperation. Histopathological finding revealed a benign cyst mass lined by simple cuboidal to non-keratinized stratified squamous epithelium. We had achieved a good surgical outcome with no complication to date for our case study. We advocate this modified surgical method to completely remove iris cyst.

    In Western Siberia (Russia) there are about 100 Artemia lakes with total area over 1 600 km2. Geographically these lakes are located between 51°-56°N and 61°-82°E. In general these lakes are shallow (depth less than 1.5 m), small or medium size (0.1 to 10 km2); they are chloride; their total salinity is from 40 to 250 g/L. The harvesting of cysts per year is only in 20-40 lakes. In Russia 550 tons of dry Artemia cysts (14%-18% of the world production) were harvested annually. This includes about 350 tons in the Altai region and 200 tons in other regions. During our regular 20-year study period the cyst harvest was: 95 tons in Kurgan; 65 tons in Omsk, 20 tons in Novosibirsk, 20 tons in Tyumen. Ways of increasing cyst harvest in Russia are considered in this article. During the last 30 years the harvest of cysts in Russia has increased from 7-20 to 500-600 tons. A significant influence of dryness of the year was found on productivity in selected lakes, but taken for all the lakes together, the relationship was not significant. The optimal salinity for productivity of cysts in the lakes was determined. Analysis of productivity of the lakes and the harvesting results showed that the stocks of cysts are underutilized by approximately 1.7 times.

    To evaluate the incidence and characteristic findings of pineal cyst incidentally detected on magnetic resonance (MR) imaging. Brain MR images obtained in 2432 patients were retrospectively reviewed to determine the incidence and MR findings of pineal cysts, which were evaluated according to their size, shape, location, signal intensity, interval change, contrast enhancement and mass effect on adjacent structures. Cysts were encountered in 107(4.4 %) of 2432 patients evaluated. their size ranged from 1 X 1 X 1 to 15 X 8 X 9 (mean, 5.97 X 3.82 X 4.82)mm. All were spherical (n=53) or oval (n=54) in shape. Their margin was smooth and they were homogeneous in nature. On T1-weighted images, the cysts were seen to be hyperintense (n=57) or isointense (n=50) to cerebrospinal fluid, but less so than brain parenchyma. T2-weighted images showed them to be isointense (n=51)or hyperintense (n=56) to cerebrospinal fluid. The cysts were centrally located in 65 cases and eccentrically in 42. Compression of the superior colliculi of the tectum was demonstrated in 17 cases (15.9 %). NO patients presented clinical symptoms or signs related to either pineal or tectal lesions. Peripheral enhancement around the cyst after Gd-DTPA injection was demonstrated in 51 cases(100 %). Follow-up examinations in 19 cases demonstrated no interval change. The incidence of pineal cysts was 4.4 %. The MR characteristics of simple pineal cysts include: (1) an oval or spherical shape, (2) a smooth outer margin and homogeneous nature, (3) isosignal or slightly high signal intensity to cerebrospinal fluid on whole pulse sequences, (4) ring enhancement after contrast injection, (5) an absence of interval change, as seen during follow up MR study. These MR appearances of pineal cysts might be helpful for differentiating them from pineal tumors.

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23-37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Full Text Available The urachus is an embryological tubular structure extending from the umbilicus to the urinary bladder apex, which usually gets obliterated but may persist uncommonly in adults. Rarely, the urachus may be the primary site of benign and malignant neoplasms. Urachal malignancies are rare and represents less than 1% of all bladder neoplasms. CASE REPORT A 39-year-old female presented with pain and lump in the lower abdomen for 6 months’ duration. No other symptoms. History of caesarean section 8 years back. On examination, a lower midline scar present. A vague swelling of size 6 x 5 cm present in the left lower abdomen adjacent to scar, surface smooth, firm, non-tender and non-reducible. Provisional diagnosed as irreducible, nonobstructing incisional hernia. Routine investigations were normal. Ultrasonogram abdomen was equivocal. CT abdomen plain and oral contrast confirmed a urachal cyst with subcutaneous component, so we planned for diagnostic laparoscopy and exploration. Intra-operatively, a 4x4 cm midline cystic mass infra-umbilical, well away from bladder dome. Abdominal component was mobilized laparoscopically using monopolar hook. A connecting component was identified entering the linea alba close to umbilicus into subcutaneous plane. Further laparoscopic dissection abandoned. A small mid-midline incision was made and both components excised in-toto. The final histopathology report came as fibrocollagenous, fibromyxoid, fibrofatty cyst wall lined by cuboidal to polygonal epithelial cells with focal atypia. Features consistent with urachal cystadenoma with focal atypia. CONCLUSION Rarely described in literature, it should be treated as mucinous cystadenoma of undetermined malignant potential which has the tendency for local recurrence should be completely excised. Followup of these tumours is mandatory, as it presents with focal atypia

    Full Text Available Purpose of the study - to study the causes of synovitis in patients with recurrent Baker’s cyst, to evaluate the effectiveness of endoscopic treatment of popliteal cysts . Materials and methods. From 2009 till 2013 we observed 34 patients with Baker's cyst. In 18 (52.9% patients of the main group endoscopic technique was applied, in 16 (47.1% patients of the comparison group a cystic bag was isolated and dissected with open technique, and then cystic gate was sutured. Results. In 10 (55,6% patients of the main group the pain disappeared in the first postoperative day (p<0,05, the average hospital stay was 3,5±0,6 days (p<0,05, and the knee function completely recovered in 16 (88.9% patients in 2 weeks postoperatively (p<0,05. A year later in 1 (5.6% patients of the main group the signs of knee function disorders of 1 degree on a Rauschning & Lindgren scale were revealed, and in the comparison group - in 6 (37.5% patients - disorders of varying severity (p <0.05. In 4 (25,0% patients of the comparison group the recurrence of Baker’s cyst developed that required arthroscopic treatment, followed by complete recovery. Conclusions: Formation of Baker’s cyst is associated with an excess formation and accumulation of a synovial fluid in the knee joint owing to chronic damage of the meniscus and synovial membrane disease (p <0,05. Endoscopic technique allows to eliminate the causes of synovitis and the valve mechanism of fluid flow in the gastrocnemius-semimembranosus bag, to stop pain at earlier date, to restore the amplitude of active movement in the knee, to reduce the hospital stay and the risk of cyst recurrence, to prevent scarring in popliteal region (p <0,05.

    Maxillary cysts are a diverse group of entities that include benign and malignant odontogenic tumors. Information on the prevalence of this disease is limited. It is more common among males, and usually occurs in the second and third decade of life. The proportion of 6 to 7 year old patients with dentigerous cysts is only 9.1%. Dentigerous cysts encompass the crown of a permanent and unerupted impacted teeth. They are usually slow growing asymptomatic lesions that are not discovered until they affect surrounding organs. The aim of this study is to present an unusual case of dentigerous cyst and to inform the pediatrician about the management of a unilateral maxillary tumor in a healthy child, underlining the importance of a multidisciplinary approach of this disease.

    2009-03-01

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    Purpose This is a clinco-histopathological study of different varieties of conjunctival cysts where modification of surgical technique was done as per requirement for intact removal of cysts to minimise recurrence rate. Materials and methods Retrospective study of 40 cases of conjunctival cysts. A thorough ocular examination and basic haematological work up was done for all patients. B-scan USG and MRI was done wherever required to see the posterior extent. All patients underwent surgical excision of cyst followed by histo-pathological examination. Results The various types of conjunctival cysts found in our study were primary inclusion cyst 12 (30%), secondary inclusion cyst 6 (15%), pterygium with cysts 15 (37.5%), parasitic cyst 4 (10%), lymphatic cyst 2 (5%), and orbital cyst with rudimentary eye 1 (2.5%). The common symptoms noted were progressive increase in size of cyst (39.45%), cosmetic disfigurement (26.23%), foreign body sensations (27.86%), proptosis (1.6%), ocular motility restrictions (3.2%) and decreased visual acuity (1.6%). The patients were followed till one year after surgical excision for any recurrence and complications and no recurrence was seen. Conclusion Careful and intact removal of conjunctival cyst is important to prevent recurrence. Minor modifications in surgical technique according to the size, site and nature of cyst help in intact removal and prevent recurrence. PMID:25892928

    We present the radiological features of a 42-years-old man with long-standing inactive ankylosing spondylitis (AS), demonstrating that arachnoiditis is a cause of a cauda equina syndrome (CES) in this disease. CT showed a dorsal arachnoid diverticulum causing scalloped erosion of the laminae, and punctate and curvilinear dural calcification. MRI revealed adhesion and convergence of the cauda equina dorsally into the arachnoid pouch, causing the dural sca to appear empty canal. To the best of our knowledge, dural calcification on CT is a new finding in AS, which may be related to the CES. Our findings support the hyopthesis that chronic adhesive arachnoiditis with subsequent loss of meningeal elasticity may be the main cause of CES in AS. (orig.)

    2014-09-28

    Pancreatic lymphoepithelial cysts are rare, benign cysts which can present diagnostic difficulties. Non-invasive imaging alone is unreliable in distinguishing between benign and malignant cysts. Endoscopic ultrasound (EUS) and fine needle aspiration (FNA) with analysis of cyst fluid is more reliable, but invasive. In addition, tumor markers such as carcinoembryonic antigen (CEA) can be grossly elevated in cyst fluid of benign cysts. We present the case of a 67 year old man with an incidental finding of a pancreatic cyst. EUS and FNA-guided aspiration of cyst fluid was performed. Fluid CEA was grossly elevated and resectional surgery was performed. On histological examination the diagnosis was confirmed as lymphoepithelial cyst of the pancreas. Tumor markers such as CEA can be elevated in the cyst fluid of benign pancreatic conditions such as lymphoepithelial cyst. Although the diagnosis is challenging preoperatively, if a systematic algorithm is followed, these conditions can be managed safely and efficiently.

    Full Text Available Hydatid disease is caused by the infestation of the larvae of tapeworms of the genus Echinococcus. The definitive hosts of Echinococcus are various carnivores, the common being the dog. All mammals (more often sheep and cattle are intermediate hosts. Humans get infected through the feco-oral route by ingestion of food or milk contaminated by dog feces containing ova of the parasite or by direct contact with dogs. The most common sites of infestation are the liver (75% and lungs (15%. Various authors state a frequency of hydatidosis of the brain ranging between only 0.2-4% of cases. [1],[2],[3] The prognosis following surgical intervention is good, especially in pediatric age. [2],[3] Hence early diagnosis of this condition is crucial. We report a rare case of a child with a large intraventricular hydatid cyst that had an excellent recovery following surgery.

    Paraurethral or Skene's duct cysts are rare causes of interlabial masses in neonates. The diagnosis of Skene's duct cysts in the neonatal period is based on its location, in relation to the urethra, and the demonstration of transitional epithelium in the cyst wall. The distinguishing features of paraurethral cysts are the displacement of urethral meatus by the mass and a cyst containing milky fluid. Thus, we report a case of a Skene's duct cyst in a newborn which was treated by incision and drainage. PMID:24049387

    Full Text Available A 5 years old male child was admitted in the Department of General Surgery, Regional Institute of Medical Sciences, Imphal, Manipur, with complaints of pain and a mass in the abdomen. On examination, abdomen was distended and a mass was felt which was cystic, non-tender, moved at right angle to the attachment of the mesentery and dull on percussion. USG and CECT Abdomen revealed a large cystic lesion in the right upper abdomen and pelvis displacing bowel loops suggestive of Omental/ Mesenteric cyst. Haematological, kidney, liver function tests and urine test were within normal limits. Exploratory laparotomy revealed a large multilobulated cystic mass in the jejunal mesentery around 15 cm from DJ junction. Grossly, the mass was 20x20 cm2, containing 4 lobules, the largest lobule measures 8x8 cm2 and weighs around 1kg. Three of the lobules were yellowish in colour and one was hemorrhagic. Excision of the cyst with 15 cm of the adjacent jejunum was done. A final diagnosis of Enterogenous cyst was made based on histopathological examination, which showed cyst wall containing smooth muscles as well as fibro connective tissues with lymphocytes in the subserosal areas with normal small intestinal mucosal tissue. Postoperative recovery was uneventful.

    Full Text Available Background: Hydrocephalus results from inadequate passage of cerebrospinal fluid (CSF from its point of production within the cerebral ventricles to its point of absorption into systemic circulation. Aims: The objective of this study was to investigate the disorders of CSF absorption by arachnoid villi during the different phases of hydrocephalus. Materials and Methods: Silicone oil was injected into the fourth ventricle of 15 canines as an experimental group. Saline solution (0.9% NaCl was injected in another nine canines as a control group. In order to block CSF transport through the cribriform plate, an external ethmoidectomy was performed in five dogs from experimental group and three dogs from control group at three days (acute stage, two weeks (sub-acute stage, and 12 weeks (chronic stage respectively. Tritiated water was injected into the canines′ cortical subarachnoid space and blood levels were measured at intervals of 1h, 4h, 8h, 16h and 48h respectively. Time-concentration curve of tritiated water was drafted. The area under the curve (AUC was calculated for variance analysis and t-testing. Results: In the chronic group, the tritiated water concentration rose slowly to a peak at 16h. It was significantly lower than other groups at 1h, 4h, 8h and 16h, but was higher than other groups at 48h. Analysis of the AUC showed significant differences among all the groups (P<0.01. There were no significant differences in the AUC between control groups, the acute group, and the sub-acute group (P>0.05; however, the AUC of the chronic group was significantly lower than other groups (P<0.05. Conclusions: The CSF absorption ability of arachnoid villi is significantly damaged in a long-term state of hydrocephalus.

    OBJECTIVE Dorsal arachnoid webs (DAWs) and spinal cord herniation (SCH) are uncommon abnormalities affecting the thoracic spinal cord that can result in syringomyelia and significant neurological morbidity if left untreated. Differentiating these 2 entities on the basis of clinical presentation and radiological findings remains challenging but is of vital importance in planning a surgical approach. The authors examined the differences between DAWs and idiopathic SCH on MRI and CT myelography to improve diagnostic confidence prior to surgery. METHODS Review of the picture archiving and communication system (PACS) database between 2005 and 2015 identified 6 patients with DAW and 5 with SCH. Clinical data including demographic information, presenting symptoms and neurological signs, and surgical reports were collected from the electronic medical records. Ten of the 11 patients underwent MRI. CT myelography was performed in 3 patients with DAW and in 1 patient with SCH. Imaging studies were analyzed by 2 board-certified neuroradiologists for the following features: 1) location of the deformity; 2) presence or absence of cord signal abnormality or syringomyelia; 3) visible arachnoid web; 4) presence of a dural defect; 5) nature of dorsal cord indentation (abrupt "scalpel sign" vs "C"-shaped); 6) focal ventral cord kink; 7) presence of the nuclear trail sign (endplate irregularity, sclerosis, and/or disc-space calcification that could suggest a migratory path of a herniated disc); and 8) visualization of a complete plane of CSF ventral to the deformity. RESULTS The scalpel sign was positive in all patients with DAW. The dorsal indentation was C-shaped in 5 of 6 patients with SCH. The ventral subarachnoid space was preserved in all patients with DAW and interrupted in cases of SCH. In no patient was a web or a dural defect identified. CONCLUSIONS DAW and SCH can be reliably distinguished on imaging by scrutinizing the nature of the dorsal indentation and the integrity of

    Intraosseous epidermoid cysts are exceedingly rare. Known as pseudotumors, not true neoplasms, intraosseous epidermoid cysts usually involve the phalanges, the skull, and the toes. Intraosseous epidermoid cysts typically present as destructive osteolytic lesions on X-ray, mimicking malignant bone tumors. Here, we present two cases of an intraosseous epidermoid cyst in the distal phalanx treated with curettage and synthetic bone graft, followed by a review of the relevant literature. In both cases, the patient presented with a painful enlargement of the fingertip following a minor trauma. Magnetic resonance imaging demonstrated lesions involving the distal phalanx that had a low signal on T1-weighted imaging (WI) and a high intensity on T2-WI. In both cases, the lesions were not enhanced by gadolinium. Good remodeling and functional recoveries were obtained. For physically active patients with substantial bone defects, synthetic bone graft may be recommended.

    Full Text Available Introduction: Dermoid cysts are congenital tumors caused by entrapment of ectoderm during embryogenesis. The most common localization are the gonads and less than 10% are in the head and neck. They are slow growing and generally observed between the second and third decades of life, being unusual in chilhood. Description: We report a case of a 5 year old male with recurrent respiratory infections, mouth breathing and snoring with apneas and daytime sleepiness. On physical examination tonsillar hypertrophy and a 4 cm sublingual tumor are detected. As complementary tests are performed overnight polysomnography with AHI of 18.3 / h and ultrasonography, reported as cystic mass with multiple rounded echogenic structures inside. Results: The patient was diagnosed with severe OSA and tonsillectomy and intraorally enucleation of tumor (as diagnosis and treatment were performed; with histopathological diagnosis of dermoid cyst. In the postoperative control we check the resolution of respiratory events and snoring. Discussion: Dermoid cysts of the oral cavity (where sublingual localization is the most common represent only 0,01% of all cysts and 1,6% of all dermoid cysts. Usually present as slow-growing asymptomatic mass, even if they reach large size can compromise swallowing, speech or breathing and eventually cause, as in our case, a severe OSA. The surgical treatment allows to confirm the diagnosis an avoid the risk of infectious complications and eventual malignant transformation.

  6. Evaluation and Treatment of Lumbar Facet Cysts.

    2016-12-01

    Lumbar facet cysts are a rare but increasingly common cause of symptomatic nerve root compression and can lead to radiculopathy, neurogenic claudication, and cauda equina syndrome. The cysts arise from the zygapophyseal joints of the lumbar spine and commonly demonstrate synovial herniation with mucinous degeneration of the facet joint capsule. Lumbar facet cysts are most common at the L4-L5 level and often are associated with spondylosis and degenerative spondylolisthesis. Advanced imaging studies have increased diagnosis of the cysts; however, optimal treatment of the cysts remains controversial. First-line treatment is nonsurgical management consisting of oral NSAIDs, physical therapy, bracing, epidural steroid injections, and/or cyst aspiration. Given the high rate of recurrence and the relatively low satisfaction with nonsurgical management, surgical options, including hemilaminectomy or laminotomy to excise the cyst and decompress the neural elements, are typically performed. Recent studies suggest that segmental fusion of the involved levels may decrease the risks of cyst recurrence and radiculopathy.

    Perineural cysts have become a common incidental finding during lumbosacral magnetic resonance (MR) imaging. Only some of the symptomatic cysts warrant treatment. The authors describe the successful operative treatment of a patient with, to the best of their knowledge, the largest perineural cyst reported to date. A 29-year-old woman had been suffering from long-standing constipation and low-back pain. During an obstetric investigation for infertility, the clinician discovered a huge presacral cystic mass. Computed tomography myelography showed the lesion to be a huge Tarlov cyst arising from the left S-3 nerve root and compressing the ipsilateral S-2 nerve. The cyst was successfully treated by ligation of the cyst neck together with sectioning of the S-3 nerve root. Postoperative improvement in her symptoms and MR imaging findings were noted. Identification of the nerve root involved by the cyst wall, operative indication, operative procedure, and treatment of multiple cysts are important preoperative considerations.

    2016-10-01

    To describe post-traumatic and congenital respiratory epithelial cysts in the orbit, which are rare lesions with only 5 and 13 published cases, respectively. We reviewed all cases of respiratory epithelial cysts diagnosed at three institutions (two tertiary referral hospitals, one private clinic) between 1995 and 2015. We describe 10 cases of post-traumatic respiratory epithelial cyst (age range 23 - 82), presenting a mean of 17.4 years after their original trauma; and 3 congenital cases (age range 17-34). All but one case underwent surgical excision of the cyst and its lining, along with any surgical implant within the cyst. Two were recurrent after incomplete excision. Three presented with acute infection within the cyst. Respiratory epithelial orbital cysts are probably commoner than the paucity of published reports would suggest. Post-traumatic cysts often present many years after trauma, and may become secondarily infected. Complete surgical removal is recommended to prevent future recurrence.

    1995-01-01

    Between 1974 and 1993, 22 patients with bronchogenic cysts were operated on in our hospital; there were 14 men and 8 women, ranging in age from 11 to 62 years, The cyst locations were mediastinal in 13 (59.1%) and intrapulmonary in 9 (40.9%). There were symptoms (chest pain and recurrent bronehiolits) in 20 patients (91%). The preoperative complications included infection in the lung and in the cyst and dysphagia due to esophageal eornpression. Chest pain was the main symptom in mediastinal cyst and recurrent infection of lung in intrapulmonary cyst. Plain chest radiograms showed that a rousd shadow, occasional air-fluid levels, and peripheral calcification may be found in cysts. An operation is the best treatment for cysts. All cysts were completely excised. No postoperative complieations, late complica-tions, or recurrence developed in our patients.

    Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage.

    A 56-year-old man presented himself for an intracranial glioblastoma multiforme excision. After being routinely monitored, he was preoxygenated. We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation.

    Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomograghy (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space.

    2003-05-01

    The inflammatory paradental cyst has been described as an entity in the WHO classification of odontogenic tumors and cysts (1992). It is mainly located at mandibular molars, in particular third molars of the lower jaw. Radiologically, involved molars show a circumscribed, mostly half-moon shaped translucency distal or distobuccal to the involved tooth. Patients frequently report episodes of infection (pericoronitis). The histological findings are identical to those of inflammatory radicular cysts. The inflammatory paradental cyst has been described infrequently in the international literature. There are no reports available in German. The aim of the present study was to present six of our own cases of inflammatory paradental cysts. Five men and one woman with an average age of 29.5 years were affected. In two cases paradental cysts occurred bilaterally. Three patients reported recurrent previous infections (pericoronitis). Radiologically, the typical translucency with clear demarcation distal to the third molars was observed. All of the third molars were vertically retained. Histologically, the inflammatory paradental cysts showed features identical to those of radicular cysts. The inflammatory paradental cyst is a clear indication for osteotomy of lower wisdom teeth. Postoperative complications or recurrences of the inflammatory paradental cysts have not been described. A correct clinical, radiological, and histopathological diagnosis of paradental cysts is mandatory, and more reports are needed in order to compile more information about relative frequency and pathogenesis of this cyst variant.

    Objective. To evaluate the surgery in simple ovarian cysts.Methods. From Jan. 1994 to Dec. 1999, 221 women with simple ovarian cysts were admitted into ourhospital. The diameter of cysts was <5 cm in 76 cases, and was≥5 cm in 145 cases ultrasonically.One hundred and eighty-four patients underwent laparosocopy, and thirty-seven underwent laparotomy.Results. Histological findings showed no malignancy in this series. Simple cysts, paraovarian cystsand corpus luteum were found histologically in 90.8% of cases with cysts <5 cm, and 60% of those withcysts >7 cm respectively, their difference was significant (X2=-37.13, P<0.001). The simple cysts, paraovar-ian cysts and corpus luteum cysts were found in 81.5% of postmenopausal women and 84.0% of pre-menopausal women. Conclusion. Patients with cysts >7 cm are indicated for surgical procedures, while a period of fol-lowup is acceptable for patients with cysts <7 cm, and surgery is advisable if the cyst is persistent dur-ing followup. Postmenopausal women with cysts should have operations.

    Background Free-floating intraocular cysts may be found in the anterior chamber (FZV) and the vitreous (FZG). The first description of a cyst was 150 years ago, and they are considered to be ocular rarities. Materials and Methods The actual knowledge about FZV and FZG is shown on the basis of two exemplary patients. Results and Discussion Patient 1 had a FZV as an incidental finding which had a smooth surface, a slight pigmentation and was translucent. The ultrasound biomicroscopy revealed an echo-free interior space. Without the patient's discomfort and missing treatment indication, a watch-and-wait strategy was chosen. Cysts of the iris can be classified as primary and secondary cysts. Primary cysts of the iris can arise from the stroma as the pigment epithelium wherein it is believed that FZV descend from the pigment epithelium. Secondary cysts and FZV can be generated by tumors, inflammation, epithelial ingrowth, the use of eye-drops or intraocular foreign bodies. Patient 2 showed marked myopic fundus changes and an FZG with a yellowish-greenish surface; the transparency was reduced and the surface was not pigmented. The ultrasound examination also revealed an echo-free interior space. Clinical controls were advised. Congenital and acquired causes are discussed for the formation of FZG. FZG could originate from the pigment epithelium of the iris, but there are conflicting study results. Trauma, inflammation and chorioretinal diseases are considered as a reason for acquired causes of FZG. The genesis, especially of FZG, is still unclear. For the treatment of patients with FZV and FZG, it is important to know the potential causes to be able to make a therapeutic decision. High quality photographic and sonographic documentation is needed in the watch-and-wait strategy. Georg Thieme Verlag KG Stuttgart · New York.

    Aneurysmal bone cysts (ABCs) are benign, expansile, blood-filled, osteolytic lesions with internal septations that may be intraosseous or extraosseous. The cysts may cause local mass effect, and changes in the regional vascular supply necessitating intervention. A case of an intracranial, intradural ABC in a young male patient with progressively severe headaches is presented. This is only the third recorded intradural case, the majority of these rare lesions being extracranial and only a minute fraction intracranial. Copyright © 2015 Elsevier Inc. All rights reserved.

    Epidermal inclusion cysts are benign cutaneous lesions caused by dermal or subdermal implantation and proliferation of epidermal squamous epithelium as a result of trauma or surgery. They are typically located on the scalp, face, trunk, neck, or back; however they can be found anywhere on the body. Lesions are asymptomatic unless complicated by rupture, malignant transformation to squamous cell carcinoma, or infection at which point they can clinically appear as more sinister pathologies. We present the case of a 45-year-old laborer with a ruptured epidermal inclusion cyst, manifesting clinically and radiographically as a malignancy. Following MRI, definitive surgical management may appear to be a logical progression in management of the patient. This case however is a good example of why meticulously following surgical protocol when evaluating an unknown soft tissue mass is imperative. By following protocol, an alternate diagnosis was made and the patient has since gone on to a make a full recovery without life transforming surgery.

    The authors present the case of a child with a colloid cyst of the velum interpositum. To the best of the authors' knowledge, this is the first reported case in the pediatric literature and only the second reported case to date. The patient was of an 11-year-old boy in whom this lesion was found after a minor head injury. He had a 6-month history of memory deficits. A lesion consistent with a colloid cyst was seen in the region of the velum interpositum, in the roof of the third ventricle. This lesion was excised successfully via a transcallosal interfornical approach. There were no new postoperative deficits and the child made a full recovery of time.

    Full Text Available This paper presents a combined surgical-prosthetic procedure of reconstructing mandibular bone defect in a 53 year old patient, following enucleation of a mandibular cyst (Cystectomy Partsch II. After a thorough diagnostic evaluation, a surgical procedure was planned with the particular attention to the nature of the disease, patient’s condition, size and extension of the cyst, tissue loss, and the possibilities of prosthetic management of a mandibular bone defect with partial postresection dental prosthesis. It is of great importance to point to the significance of teamwork of a maxillofacial surgeon and a specialist in prosthodontics. This kind of cooperation provided very effective and less risky soft tissue, as well as bone tissue regeneration (osteogenesis. The patient’s recovery was fast, and he could return to his daily activities and work without significant changes regarding quality of life after surgery and prosthetic treatment.

    2003-01-01

    Full Text Available The arachnoid granulations of adult individual of both sexes were studied through scanning electron microscopy. The dura mater and arachnoid meninges of individuals were collected at the Service of Death Verification of São Paulo - USP and fixed in Karnovsky solution. After this period the material was prepared for analysis in electron microscope. Our results demonstrated that the arachnoid granulations are formed by a pedicle, body and apex, being surrounded by a capsule of connective tissue, which in turn is composed of, basically, bundles of collagen fibers that line pores of different shapes and sizes. The smaller pores are lined by tiny bundles and are located at the apical region of the granulation and the larger are lined by thicker bundles and are located at the lateral regions. In the body we verified that the bundles of collagen fibers compose a fibrous meshwork and in some regions these bundles have circular orientation, forming pores similar to those found at the region of the capsule.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst.

    Full Text Available Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

    Mediastinal parathyroid cysts are very rare. Since the first report by DeQuervain, 19 cases have been reported. We encountered a case of mediastinal parathyroid cyst presenting as displacement of the trachea. The cyst originated in the lower portion of the left lobe of the thyroid gland and extended to the mediastinum, displacing the trachea and the esophagus. The monolocular mass was a thin walled cyst, and mognetic imaging indicated that it contained watery fluid. The left lobe of the thyroid gland was found to be displaced upward by the tumor, on thyroid scintigram done with technetium-99, which suggested that the cyst originated in the parathyroid gland.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst. PMID:22787551

    Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning. PMID:26180645

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion. The cysts are relatively rare and most of them are asymptomatic. Some Tarlov cysts can exert pressure on nerve elements resulting in pain, radiculopathy and even multiple radiculopathy of cauda equina. There is no consensus on the appropriate therapeutic options of Tarlov cysts. The authors present a case of two sacral cysts diagnosed with magnetic resonance imaging. The initial symptoms were low back pain and sciatica and progressed to cauda equina syndrome. Surgical treatment was performed by sacral laminectomy and wide cyst fenestration. The neurological deficits were recovered and had not recurred after a follow-up period of nine months. The literature was reviewed and discussed. This is the first reported case in Thailand.

    Full Text Available A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

    Full Text Available Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts. Unlike a mucocele, which is surrounded by granulation tissue, the salivary duct cyst is lined by epithelium. Salivary duct cysts are more common in the oral minor salivary glands and rarely occur in the major salivary glands, show a marked predilection for the superficial lobe of the parotid, and represent 10% of all salivary gland cysts. Neoplastic differentiation of the lining of the salivary duct cyst has been reported. We report a case of a salivary duct cyst of the left parotid gland, with a review of radiographic and histopathologic features.

    Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used.

  1. New insights about suprapatellar cyst

    Directory of Open Access Journals (Sweden)

    Tomislav Crnkovic

    2012-02-01

    Full Text Available bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery.

  2. Baker's Cyst: Diagnostic and Surgical Considerations.

    2015-07-01

    Popliteal synovial cysts, also known as Baker's cysts, are commonly found in association with intra-articular knee disorders, such as osteoarthritis and meniscus tears. Histologically, the cyst walls resemble synovial tissue with fibrosis evident, and there may be chronic nonspecific inflammation present. Osteocartilaginous loose bodies may also be found within the cyst, even if they are not seen in the knee joint. Baker's cysts can be a source of posterior knee pain that persists despite surgical treatment of the intra-articular lesion, and they are routinely discovered on magnetic resonance imaging scans of the symptomatic knee. Symptoms related to a popliteal cyst origin are infrequent and may be related to size. A PubMed search was conducted with keywords related to the history, diagnosis, and treatment of Baker's cysts-namely, Baker's cyst, popliteal cyst, diagnosis, treatment, formation of popliteal cyst, surgical indications, and complications. Bibliographies from these references were also reviewed to identify related and pertinent literature. Clinical review. Level 4. Baker's cysts are commonly found associated with intra-articular knee disorders. Proper diagnosis, examination, and treatment are paramount in alleviating the pain and discomfort associated with Baker's cysts. A capsular opening to the semimembranosus-medial head gastrocnemius bursa is a commonly found normal anatomic variant. It is thought that this can lead to the formation of a popliteal cyst in the presence of chronic knee effusions as a result of intra-articular pathology. Management of symptomatic popliteal cysts is conservative. The intra-articular pathology should be first addressed by arthroscopy. If surgical excision later becomes necessary, a limited posteromedial approach is often employed. Other treatments, such as arthroscopic debridement and closure of the valvular mechanism, are not well studied and cannot yet be recommended.

  3. Intraparenchymal epidermoid cysts in the brain: diagnostic value of MR diffusion-weighted imaging

[Medical Imaging Center, The First Affiliated Hospital of Suzhou, Jiangsu Province (China)

    Aim: To evaluate the value of magnetic resonance (MR) diffusion-weighted imaging (DWI) and apparent diffusion coefficients (ADC) maps in the diagnosis of intraparenchymal epidermoid cysts (ECs). Materials and methods: Six cases of histopathologically proven intraparenchymal ECs were studied. All patients were examined with conventional MR (T1WI, T2WI, contrast-enhanced T1WI) and DWI sequences. Along with the mean ADC values (mADC) of the ECs, the cerebrospinal fluid (CSF) and grey matter (GM) were measured. Qualitative and quantitative assessments, as well as MRI findings, were retrospectively analysed using a double blind method by three radiologists in consensus. Results: Four lesions were located in the cerebellum, among them, one was accompanied by an arachnoid cyst; one huge lesion crossed the parenchyma of the frontal and temporal lobes; the other was located in the left temporal lobe. Two lesions had a homogeneous CSF-like intensity on both T1WI and T2WI. The other four were of mixed-intensity on both T1WI and T2WI. All lesions were strikingly hyperintense on DWI, and iso- or slightly hypointense on ADC (relative to the brain). The mADCs of the ECs were significantly higher than that of GM, but significantly lower than that of CSF. Three cases (3/6) were accurately diagnosed using conventional MR sequences without DWI, but in the remaining three cases, correct diagnosis could only be made with help of DWI. Conclusion: DWI sequences can facilitate the diagnosis of intraparenchymal ECs, thus alerting surgeons of the risk of chemical meningitis at surgery. The MR findings of intraparenchymal ECs are basically as the same as those of extracerebral ECs, but the former is likely to have a mixed signal. The hyperintense signal of ECs on DWI is probably caused by the T2 shine-through effect in tumour tissue.

  4. Congenital cervical bronchogenic cyst: A case report

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Background. Discal cyst has been identified as a rare cause of low back pain and radiating leg pain. The pathogenesis and management of this condition are still debated. The largest number of reported cases had undergone microsurgery while very few cases have been treated with percutaneous endoscopic discectomy (PED). Methods. An 18-year-old boy complained of low back pain radiating to right leg after a minor road traffic accident. Diagnosis of a discal cyst at L4-L5 level was made based on magnetic resonance imaging (MRI). Despite conservative management for 6 months, the low back pain and radiating leg pain persisted so surgical treatment by PED was performed under local anesthesia. As the patient was a very active baseball player, his physician recommended a minimally invasive procedure to avoid damage to the back muscles. Results. The patient's low back pain and leg pain disappeared immediately after surgery and he made a rapid recovery. He resumed mild exercise and sports practice 4 weeks after surgery. Complete regression of the cystic lesion was demonstrated on the 2-month postoperative MRI. Conclusion. A minimal invasive procedure like PED can be an effective surgical treatment for discal cyst, especially in active individuals who play sports. PMID:26357581

    Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored.

    Full Text Available Intraosseous ganglia are benign cysts that usually can be seen in lower extremity; especially around ankle. These cysts have fewer incidences in upper extremity, mainly around the wrist. They are extremely rare in olecranon. These lesions are often asymptomatic. Patient was a 75-year-old man who had trauma many years ago. When he came to our clinic, he complained of severe pain around his elbow that he could not do ordinary activity. He had local tenderness in elbow and 30 degree limitation in extension. In radiography, lytic, multiloculated lesion existed in region of olecranon. After excisional biopsy was done, cavity was cleaned completely with curette and was filled with autogenous bone. At 10-year follow-up, the patient was completely asymptomatic. Control radiograph showed cavity filled completely by bone; there was no evidence of relapse.

    A soft tissue aneurysmal bone cyst located in the right gluteus medius of a 21-year-old man is reported. On conventional radiography, the lesion demonstrated a spherically trabeculated mass with a calcific rim. On CT scan, it showed a well-organized peripheral calcification resembling a myositis ossificans. On MRI, it presented as a multilocular, cystic lesion with fluid-fluid levels. The lesion had no solid components except for intralesional septa. Although findings on imaging and histology were identical to those described in classical aneurysmal bone cyst, diagnosis was delayed because of lack of knowledge of this entity and its resemblance to the more familiar post-traumatic heterotopic ossification (myositis ossificans).

    Full Text Available In the oro-facial region cystic lesions of different etiologies are encountered owing to the presence of the teeth in the jaw bones. A bewildering variety of developmental, odontogenic and non-odontogenic cysts are seen. Epidermoid cyst is a rare developmental cyst of the oro-facial region which results from entrapped epidermal elements without adnexal appendages. Dermoid and epidermoid cysts occur in oro-facial region with an incidence of 6.9-7% and represents less than 0.01% of all oral cavity cysts. Here we report two cases of epidermoid cysts occurring at unusual locations involving upper left maxillary region lateral to the nose and pinna of the ear.

    Full Text Available Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland and the oral cavity (usually the floor of the mouth. there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography.It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management.

    We present 3 cases with peripheral neuropathies of the median, posterior interosseous, and ulnar nerves associated with rheumatoid synovial cysts of the elbow joint. Magnetic resonance imaging and electrophysiological examination led to the final diagnosis of the relation to synovial cysts of the elbow joint. All patients underwent surgical decompression of these nerves and synovectomy of the elbow joint. Functional recovery was excellent in the 2 patients with median and posterior interosseous nerve palsy but incomplete in the patient with ulnar nerve palsy. Such neuropathies require consideration in the differential diagnosis of wrist and hand disability in patients with rheumatoid arthritis. This awareness should enhance early diagnosis and treatment by surgical decompression.

    Echinococcosis is endemic in various regions of Turkey. Cardiac involvement in echinococcosis is rare, and lone cardiac hydatid cysts are even more unusual. Because cardiac hydatid disease can be fatal, even asymptomatic patients are optimally referred for surgical treatment. We present a rare case of a lone, primary, mobile hydatid cyst in the left atrium of a 62-year-old woman. The cyst caused dyspnea from left ventricular inflow obstruction. In addition to reporting the patient's fatal case, we discuss cardiac hydatid cysts in terms of the scant medical literature. PMID:27303247

    A radiologic study of 139 dentigerous cysts (128 patients) indicated the followings: 1. There was higher incidence in males (62.99%) than in females (37.01%). The most common age group was 11-20 years and the average age was 23.6 years. 2. The most common clinical symptoms was swelling of the jaws (49 cases, 33.09%), and no symptoms was presented in 26 cases (18.71%). 3. Dentigerous cysts were found to be slightly more common in the maxilla (53.24%) than in the mandible (46.76%) and there was almost no difference in occurrence between right and left side. The maxillary supernumerary tooth was the most frequent site of the dentigerous cyst and no dentigerous cyst was found to be related to a deciduous tooth. 4. The most common radiographic findings was root resorption of the adjacent teeth (33.09%), and the central dentigerous cysts were 78 cases (56.12%), the lateral dentigerous cysts were 61 cases (43.88%). 5. The increased radiolucency at the crown portion of the tooth in a cystic cavity was seen in 44 cases (31.65%), and a case of dentigerous cyst was found in a edentulous patient, and 16 cases of multiple dentigerous cysts were found in 5 patients. 6. The ameloblastic changes in 8 cases, the keratinization of the cyst wall in 2 cases, and a case of epidermoid carcinoma were confirmed microscopically.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

    2007-09-01

    Full Text Available Foregut cysts are various congenital lesions originated from emberyonic foregut. Bronchogenic, enterogenous and neuroenteric cysts are the most frequent forms of foregut cysts. They create different clinical symptoms based on their location. Enterogenous cysts comprise 4-5 percent of posterior mediastinal cysts and include esophageal, gastric and enteric cysts. A 61 year old woman referred to surgical clinic with dysphasia and regurgitation 6 months ago whose illness aggravared over the last 3 months. In physical examination, a lesion was seen in the right site of posterior mediastinum. Surgical excision was done and a ciliated columnar epithelium with two thin muscular layers were reported in pathology. In reality, the distinction between esophageal and bronchogenic cysts is not always clear. Both cysts present in mediastinum and their epithelial tissues are non-specific, however presence or lack of muscle layer in cyst-wall, proximity to gastrointestinal tract or tracheobronchial tree, adaption of clinical symptoms with paraclinic results and observations during surgical procedure can reveal certain diagnosis.

    Hip labral impingement can cause labral tears and secondary paralabral cyst formation. Femoroacetabular impingement is the main cause of labral impingement, but other conditions such as iliopsoas tendon impingement are described. There is no description of labral cyst resulting from psoas impingement treated arthroscopically in the literature. We present the case of a young sportsman with groin pain caused by psoas impingement with a labral tear and secondary paralabral cyst who was treated arthroscopically by cyst debridement, psoas tenotomy, and labral repair.

    Dermoid cyst of the parotid gland is a rare clinical entity. Definitive clinical diagnosis is often difficult to determine preoperatively because of the lack of pathognomonic features. The most frequent location of a parotid dermoid cyst is a triangular area lying above the pinna. Imaging studies do not definitely diagnose a parotid dermoid cyst. Although parotid dermoid cyst is (generally) well-encapsulated, complete removal of the cyst wall is not sufficient to cure it, so it is mandatory to perform careful excision of the cyst by parotidectomy, in terms of preserving facial nerve integrity. Histopathology of the parotid gland tumor removed by parotidectomy makes a diagnosis of certainty, by revealing a cyst wall with keratinization of the squamous epithelium and the presence of skin annexes (hair follicles, sweat glands, sebaceous glands). We present a rare case of parotid dermoid cyst in a 21-year-old male patient with symptoms and imaging rather suggestive of arch I branchial cyst and a brief review of data in the medical literature of the last 20 years.

    Full Text Available Cholecystitis can result in complications if not completely treated. These include gallbladder empyema, perforation and cholecystoenteric fistula.We report the first incidence of cholecystitis resulting in a gallstone fistula with a gastric duplication cyst. A 71 year old patient presented with generalised peritonism that was worst in the epigastric area. Computer tomography (CT revealed a perforated necrotic gallbladder. Emergency laparotomy, cholecystectomy, partial gastrectomy and Roux-en-Y reconstruction was required. The patient made a slow but full recovery.Pathology results revealed that chronic cholecystitis had resulted in a fistula with a duplication cyst overlying the greater curve of the stomach. Several one centimeter gallstones were found within the cyst cavity.

    2008-09-01

    Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.

  14. The clinical relevance of Tarlov cysts.

    Science.gov (United States)

    Langdown, Andrew John; Grundy, Julian R B; Birch, Nicholas C

    2005-02-01

    The sacral perineural cyst was first described by Tarlov in 1938 as an incidental finding at autopsy. There are very few data in the literature regarding the role of Tarlov cysts in causing symptoms, however. Most studies report low numbers, and consequently, the recommendations for treatment are vague. Our aim, therefore, is to present further detail regarding the clinical relevance of Tarlov cysts and to identify whether or not they are a cause of lumbosacral spinal canal stenosis symptoms. Over a 5-year period, 3535 patients underwent magnetic resonance imaging (MRI) scan for lumbosacral symptoms. Fifty-four patients were identified as having Tarlov cysts, and their clinical picture was correlated with the findings on MRI. The majority of Tarlov cysts (n = 38) cannot be held responsible for patients' symptoms and are clinically unimportant. However, we encountered several patients in whom Tarlov cysts (n = 9) occurred at the same level as another pathology. In these cases, the cyst itself did not require any specific therapy; treatment was directed at the other pathology, and uneventful symptom resolution occurred. A smaller subgroup of cysts (n = 7) are the main cause of patients' symptoms and may require specific treatment to facilitate local decompression. The majority of Tarlov cysts are incidental findings on MRI. Where confusion exists as to the clinical relevance of a Tarlov cyst, treatment of the primary pathology (ie, non-Tarlov lesion) is usually sufficient. Tarlov cysts may, however, be responsible for a patient's symptoms; possible mechanisms by which this may occur and treatment strategies are discussed.

  18. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Background Parathyroid cyst is an infrequent and unsuspected disease. There are more than 300 hundred cases reported in the world literature, a few of them are from Latin America. The experience of our centers and a review of the cases are presented. Methods Case report of a series of patients with parathyroid cyst from our institutions according to the CARE guidelines (Case Reports). A search of Medline, Embase, BIREME (Biblioteca Regional de Medicina) LILACS (Literatura Latinoamericana y del Caribe en Ciencias de la Salud), Google Scholar and Scielo (Scientific Electronic Library on Line) databases and telephonic or email communications with other experts from Latin-America was performed . Results Six patients with parathyroid cyst were found in our centers in Colombia. Most of them were managed with aspiration of the cyst. Two of them required surgery. Only one case was functional. Twelve reports from Latin America were found for a total of 18 cases in our region adding ours. Conclusions Parathyroid cysts are uncommonly reported in Latin America. Most of them are diagnosed postoperatively. Suspicion for parathyroid cyst should be raised when a crystal clear fluid is aspirated from a cyst. The confirmation of the diagnosis may be easily done if parathyroid hormone (PTH) level is measured in the cyst fluid. PMID:28149800

    Full Text Available Background: Different research groups reported a negative correlation between cancers and parasitical infections. As an example, the prevalence of a hydatid cyst among patients with cancer was significantly lower than its prevalence among normal population. Tn antigens exist both in cancer and hydatid cyst. This common antigen may be involved in the effect of parasite on cancer growth. So in this work, common antigens between hydatid cyst and cancers have been investigated. Materials and Methods: Different hydatid cyst antigens including hydatid fluid, laminated and germinal layer antigens, and excretory secretory antigens of protoscolices were run in SDS PAGE and transferred to NCP paper. In western immunoblotting, those antigens were probed with sera of patients with different cancer and also sera of non-cancer patients. Also, cross reaction among excretory secretory products of cancer cells and antisera raised against different hydatid cyst antigen was investigated. Results: In western immunoblotting, antisera raised against laminated and germinal layers of hydatid cyst reacted with excretory secretory products of cancer cells. Also, a reaction was detected between hydatid cyst antigens and sera of patients with some cancers. Conclusion: Results of this work emphasize existence of common antigens between hydatid cyst and cancers. More investigation about these common antigens is recommended.

    Full Text Available Aim: Thoracoscopy offers great advantages when compared with open surgery in terms of postoperative pain and pulmonary complications. Considering the benign nature of most of the mediastinal cysts, thoracoscopy is safe and feasible with minimal morbidity. The purpose of this article is to review our experience with four cases of mediastinal cysts resected successfully within a period of one year by thoracoscopy. Materials and Methods:The cases of mediastinal cysts operated by thoracoscopic excision in K.E.M. Hospital, Mumbai from November 2005 to December 2006 were reviewed. The age varied from six months to 10 years. The patients presented with respiratory distress or recurrent lower respiratory tract infection. All patients underwent Chest X-ray and CT scan thorax to delineate the location of the cyst and its relationship with adjacent vital structures. Two patients had anterior and two had posterior mediastinal cyst. The ports were placed depending on the location of the cyst on the CT scan, following the principles of triangularization. The cysts were excised mainly by blunt dissection. Results: All the patients were successfully managed by thoracoscopic surgery. None of them had intraoperative complications. Dissection in patient with history of recurrent respiratory tract infection was difficult because of adhesions. Intercostal drain was removed within 48hrs and the patients were discharged on the fourth postoperative day. Conclusions: Thoracoscopy in mediastinal cysts is a safe and effective procedure with low morbidity and a shorter hospital stay.

    Directory of Open Access Journals (Sweden)

    S.W. Lim

    2011-01-01

    Full Text Available Tailgut cysts, or retrorectal cystic hamartomas, are rare congenital developmental lesions, most commonly located in the retrorectal space, and are more common in women. We present a case of retrorectal tailgut cyst managed using a laparoscopic approach. A 36-year-old woman presented with incidentally detected retrorectal tumors during evaluation for a gallbladder polyp. Her past medical history revealed that she had undergone cesarean section twice. The tumor marker CA 19-9 level was 42.52 U/ml. CT of the pelvis with contrast and pelvic MRI revealed a 3.9 × 3.3 cm well-defined, homogeneous cystic mass in the right presacral area, and a 2.5 × 1.5 cm cystic mass in the precoccygeal space. The patient underwent laparoscopic exploration with a preoperative diagnosis of tailgut cysts based on radiological findings. The operative time was 90 min including 30 min of subsequent laparoscopic cholecystectomy without placement of additional trocars. The surgical specimens consisted of two fragments of fibrofatty tissues, unilocular cystic masses. The final pathologic diagnosis was tailgut cysts with no evidence of malignancy. Postoperative recovery was uneventful, and the patient was discharged after 3 days. In conclusion, surgical resection is recommended in the management of retrorectal tailgut cyst to establish a definite diagnosis and to rule out malignancy. The laparoscopic approach is a feasible and safe option.

    Weaver, A D

    1978-05-20

    A description is given of the history, clinical features, surgery, outcome and pathology of 12 dogs with discrete prostatic cysts over 50 ml in volume. The dogs were middle-aged and presented with either urinary or alimentary signs or both. The cyst was usually palpable in the posterior abdomen as a smooth, non-painful mass, readily demonstrable on contrast radiography (pneumocystogram). Attempts were made to drain and resect the cysts, but resection often proved difficult due to its attachment to the region of bladder neck and ureters. In no case could the origin be shown to be from an enlarged uterus masculinus. The cyst content was invariably sterile, but its nature and the pathology of the cyst wall varied considerably between individuals. Since the long-term outcome was only satisfactory in three cases, the prognosis must be guarded.

    2006-01-01

    Full Text Available A case of intraprostatic cyst is reported. The patient presented with a completely evacuated hydatid cyst of the prostate. The intraprostatic cystic cavity that was communicating with the urethra developed urinary stones. The patient had transurethral resection of the prostate, the stones in the cyst were pushed into the bladder and fragmented using a ballistic lithotripter. Pathological examination concluded to a prostatic hydatid cyst that had evacuated through the urethra and was complicated by stone formation within the residual cavity. Postoperative course was uneventful and follow-up did not show evidence of recurrence. This is the first case of hydatid cyst of the prostate to present as an intraprostatic stone pouch.

    2012-07-01

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

    2013-03-01

    During Acanthamoeba castellanii trophozoite-cysts differentiation, four morphological stages were identified by scanning electron microscopy: trophozoite, precyst, immature cysts, and mature cysts. Fluorescence microscopy reveals the presence of small cumulus of actin in the cytoplasm of precysts after treatment with rhodamine phalloidin. By the contrary, in mature cysts, fluorescence was not observed. However, when excystation was induced, large fluorescent patches were present. By transmission electron microscopy, encysting amebas showed small cytoplasmic vesicles containing fibrillar material, surrounded by a narrow area of thin fibrils. Similar appearance was observed in pseudopods and phagocytic invaginations. In addition, large aggregates of rod-shape elements, similar to the chromatoid bodies, described in other amebas, were present in the cytoplasm. These cysts presented large areas with orange fluorescence after treatment with acridine orange.

They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    Lateral meniscal cysts are relatively common, but only in rare instances do they cause common peroneal nerve irritation. There are, we believe, no cases reported in which both the sensory and motor functions of the nerve have been compromised. We present a case of a lateral meniscal cyst that became palpable and led to symptoms of numbness and weakness in the distribution of the common peroneal nerve. The MRI findings were of an oblique tear of the lateral meniscus with an associated multiloculated meniscal cyst that coursed behind the biceps tendon before encroaching on the common peroneal nerve. Surgical resection confirmed the tract as located on the MRI and histology confirmed the mass to be a synovial cyst. Resection of the cyst and arthroscopic excision of the meniscal tear led to resolution of the symptoms in 3 months. (orig.)

    Full Text Available Background. A six-year-old boy presented with a large progressive intracorneal and scleral cyst. Two years before, bilateral cataract surgery through a 6.5-mm corneal incision was performed elsewhere.Methods. The posterior wall of the cyst could be excised, as well as the anterior wall in the sclera. Upon histo-pathology the cyst wall was lined by epithelium. The epithelial cells of the anterior side in the cornea were removed with a curette and a corpus alienum drill. Three and a half years after removal of the cyst, there was no recurrence. Visual acuity was 0.8. Conclusions. An intracorneal and scleral inclusion cyst was successfully removed by surgical excision and the removal of epithelial cells by a curette and a corpus alienum drill.

    Case 1: A lower abdominal large painful mass was recognized by palpation, CT scan and ultrasonography in a 64-year-old house wife. Urine cytology was negative. The mass at the dome of bladder was covered with normal epithelium cystoscopically. Aspiration cytology of the lower abdominal mass demonstrated no malignancy and total excision of urachal remnant with a portion of bladder wall was carried out. Histologically, the mass was an urachal cyst with granulomatous change infected with C group beta-streptococcus. Case 2: A 46 year-old male engineer complained of asymptomatic hematuria. Cystoscopic examination revealed a small bleeding lesion at the dome of bladder. Urine cytology was negative. CT scan and ultrasonography revealed a tiny cystic mass lesion with irregular density. Biopsy or aspiration cytology appeared difficult because of the size and localization of the mass. En bloc segmental resection of urachal remnant was carried out. Since intraoperative rapid histological examination of the specimen confirmed no malignancies, dissection of pelvic lymph node was not performed. Urachal cysts presented above were suspicious of malignant degeneration from findings of imaging examination. Either preoperative or intraoperative histological examination in such cases appears to be indispensable to avoid unnecessary extensive operation as well as to perform radical operation required for malignant lesions.

    2015-01-01

    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

    Epidermoid cysts are common benign cysts which occur particularly on the skin of the face, neck and upper trunk. Subconjunctival location of these cysts is very rare and, until today, only seen in patients with Gorlin-Goltz syndrome. Histopathological examination of these cysts show similarities with odontogenic keratocysts, a typical clinical manifestation of Gorlin-Goltz syndrome.

    Ganglion cysts of the temporomandibular joint are very rare and always misdiagnosed as synovial cyst, parotid gland tumor, or other cystic lesions. They present with pain, swelling, or dysfunction. Image studies could facilitate to identify the tumor mass from the adjacent soft tissue, but a definitive diagnosis could be made from the pathologic report.A 59-year-old woman presented to the clinics with a chief complaint of a painless swelling mass in the right preauricular region of 3-month duration. Computed tomography was performed, which showed a small radiolucent lesion adjacent to the right condyle. Local excision was performed, and the specimen was sent for histologic examination.Microscopic examination showed a cystic space walled by dense fibrous connective tissue without epithelial or endothelial lining. Immunohistochemical staining of these lining cells showed positivity for vimentin and negativity for cytokeratin. These findings were consistent with the diagnosis of ganglion cyst.Ganglion cysts present as unilobulate or multilobulate cysts that arise from the collagenous tissue and is filled with highly viscous fluid. It does not communicate with the joint cavity. In contrast, synovial cyst is a true cyst lined by cuboidal or flattened cells from the synoviocytes and is filled with gelatinous fluid. It may or may not communicate with the joint cavity. Excision is the treatment of choice of symptomatic cystic lesions. Incomplete excision of these lesions may cause further recurrence or infection. Thus, injection of hydrocortisone or aspiration may be considered as an alternative management.

    To report the clinical findings, diagnosis, treatment and outcome of equine patients with articular synovial cysts. Retrospective case series. Horses (n = 16) with articular synovial cysts. Horses diagnosed with articular synovial cysts (1988-2009) at 2 veterinary teaching hospitals were studied. Signalment, history, clinical signs, diagnostic methods and treatment were retrieved and telephone follow-up was obtained. Sixteen horses with articular synovial cysts were identified. Lameness was the reason for referral in most (n = 9) horses. Diagnosis was based on a combination of palpation and imaging studies, including radiography, ultrasonography and/or arthrography. Excision of the cyst was performed in 8 horses. Outcome was available for 4 surgically and 2 conservatively treated horses. Lameness resolved in 3 horses treated surgically and the 4th died for unrelated reasons. The 2 conservatively treated horses performed satisfactorily for the rest of their career. Equine articular synovial cysts are rare and can be associated with lameness. The cysts had a synovial lining in all horses where it was assessed. Surgical excision may be successful in resolving the lameness and allowing selected horses to return to work. © Copyright 2012 by The American College of Veterinary Surgeons.

    Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

    Full Text Available Abstract Background It is acknowledged that total cyst excision is a safe and ideal surgical treatment for congenital biliary duct cyst, compared to simple internal drainage. The aim of this study was to determine the optimal operation occasion and the effect of laparoscopy on congenital biliary duct cyst based upon total cyst excision. Methods From January 2002 to January 2011, 217 patients were admitted to Southwest Hospital for congenital biliary duct cyst. To determine the optimal surgery occasion, we divided these subjects into three groups, the infant group (age ≤ 3 years, the immaturity group (3 18 years, and then evaluated the feasibility, risk and long-term outcome after surgery in the three groups. To analyze the effect of laparoscopic technique on congenital biliary duct cyst, we divided the patients into the laparoscopy and the open surgery groups. Results Among the three groups, the morbidity from cholangiolithiasis before surgical treatment had obvious discrepancy (p 0.05. Similarly, no significant discrepancy was observed in the morbidity from postoperative complications or long-term postoperative complications (p > 0.05 between the laparoscopic and the open surgery groups. Conclusions We conclude that total cyst excision should be performed as early as possible. The optimal treatment occasion is the infant period, and laparoscopic resection may be a new safe and feasible minimally invasive surgery for this disease.

    The authors report the case of a giant medial meniscal cyst in an osteoarthritic knee of an 82-year-old woman that was successfully treated with only arthroscopic cyst decompression. The patient noticed a painful mass on the medial side of the right knee that had been gradually growing for 5 years. Magnetic resonance imaging showed an encapsulated large medial cystic mass measuring 80×65×40 mm that was adjacent to the medial meniscus. An accompanying horizontal tear was also detected in the middle and posterior segments of the meniscus. The medial meniscus was resected up to the capsular attachment to create bidirectional flow between the joint and the cyst with arthroscopic surgery. Magnetic resonance imaging performed 14 months postoperatively showed that the cyst had completely disappeared, and no recurrence was observed during a 2-year follow-up period. An excellent result could be obtained by performing limited meniscectomy to create a channel leading to the meniscal cyst, even though the cyst was large. Among previously reported cases of meniscal cysts, this case is the largest to be treated arthroscopically without open excision.

    The purpose of this study is to assess the prevalence of abnormal CT findings in patients with surgically proven ruptured endometriotic cysts, as compared with those abnormal CT findings of ruptured ovarian functional cysts. This study included 13 retrospectively identified patients with surgically confirmed ruptured ovarian endometriotic cysts and who had also undergone preoperative CT scanning during the previous seven years. As a comparative group, 25 cases of surgically confirmed ruptured ovarian functional cysts were included. We assessed the morphologic features of the cysts and the ancillary findings based on CT. For the endometriotic cysts, the mean maximum cyst diameter was significantly larger than that of the functional cysts (70.1 mm versus 36.4 mm, respectively, p < 0.05). The endometriotic cysts frequently had a multilocular shape and a thicker cyst wall, as compared to that of functional cysts, and these differences were statistically significant. Among the ancillary findings, endometriotic cysts showed a significantly higher prevalence of loculated ascites, ascites confined to the pelvic cavity without extension to the upper abdomen, and peritoneal strandings and infiltrations (p < 0.05). Although 11 of the 25 cases of functional cysts showed active extravasation of contrast material at the ovarian bleeding site, only one of 13 cases of endometriotic cysts showed active extravasation. The diagnosis of ruptured endometriotic cyst should be suspected for a woman in whom CT reveals the presence of multilocular or bilateral ovarian cysts with a thick wall and loculated ascites confined to the pelvic cavity with pelvic fat infiltrations

    Full Text Available Abstract Epidermoid and dermoid cysts represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are found, and teratoid cysts when other tissue such as muscle, cartilage, and bone are present. In this article, we present the case of an epidermoid cyst, with an oral as well as a submental component, in an 11 year old boy who presented with complaints of a mass in the oral cavity, difficulty chewing and swallowing of solid foods for about 3 years. He was admitted to the otolaryngology department. On examination, a mass displacing the tongue superiorly and posteriorly was noticed. An MRI scan was done and showed a 40 × 35 mm well-circumscribed non-enhancing cystic mass extending from the sublingual area to the level of the thyroid notch. The content of the cyst was homogenous. On examining the neck, a firm swelling was also noticed in the submental area, extending down to the thyroid notch. Under general anesthesia and with nasotracheal intubation, the patient underwent surgical removal of the mass. Extraorally, a midline submental horizontal incision was performed through the mucosa overlying the swelling and the cyst was dissected from the surrounding tissues and removed. On histological examination, acidophilic stratum corneum and basophilic dot like staining of stratum granulosum, which is the hallmark of an epidermoid cyst, were seen. The patient did well postoperatively, and no recurrence was noticed at the 6-months follow-up.

    Full Text Available The first prenatal detection of an ovarian cyst was by Valenti in 1975. Since then antenatal and neonatal ovarian cysts are encountered more frequently due to the improvement of imaging techniques as well as routine antenatal ultrasound scanning. We discuss here the laparoscopic management of three cases of neonatal ovarian cysts. This approach is well tolerated by neonates, and it may overcome the controversy between the ′wait and see′ policy and early surgical intervention, as laparoscopy has both diagnostic and therapeutic value with minimal morbidity, and ovarian salvage whenever possible.

    17-year-old and 14-year-old brothers were referred for evaluation of the cystic lesions on the mandibular anterior area with no symptoms. Neither their mother nor the brothers could recall any past trauma to those areas. Panoramic and intraoral radiographs revealed moderately defined cystic lesions on their mandibular anterior areas. Biopsies on both lesions revealed simple bone cysts. Hereditary cause or familial history of simple bone cysts could not be found in literature review. This case may have been a coincidence. However, further investigation is needed to find the cause of simple bone cysts occurring in patients those are closely related.

    Pulmonary multi-vesicular hydatid disease (HD) with Echinococcus granulosus is rare. A 28-year-old woman presented to our center with cough and respiratory distress. Chest x-ray and computerized tomography scan revealed bilateral giant cysts with water-lily sign (ruptured hydatid cysts). The left cyst was in vicinity of heart. With thoracotomy cysts of both lungs were removed. Thousands of translucent, homogenized small daughter cysts were discovered from the left side cyst. Pathologic examinations revealed the ruptured hydatid cysts of both lungs with daughter cysts on the left lung cyst. To best of our knowledge probably this is the first report of multi-vesicular HD in lung. We suppose that the heart pulsation was effective in the formation of daughter cysts.

    2017-01-01

    Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst. During laparotomy, however, it was found to be an enteric duplication cyst with volvulus. To our knowledge, there has been no report of an enteric duplication cyst presenting as a wandering abdominal mass. Our experience indicates that early intervention is necessary for patients who have a wandering abdominal mass to avoid complications and urgent surgery, whether it is an ovarian cyst or an enteric duplication cyst.

    Full Text Available Botryoid odontogenic cyst (BOC is considered to be a polycystic variant of the lateral periodontal cyst (LPC as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    The ischiorectal fossa may give rise to a wide variety of pathological entities, although it is composed of relatively few structures. Developmental cysts are included among the list. Large epidermoid cysts in the ischiorectal fossa have been previously described (Fujimoto et al., Clin Imaging 17:146-148, 1993; Ng et al., Can J Surg 49:435-436, 2006). However, to the best of our knowledge, there is no published case in the English literature of a dermoid cyst within the ischiorectal fossa. Using magnetic resonance (MR) imaging and a subsequent ultrasound-guided biopsy, we were able to offer a focused differential that included a dermoid cyst within the ischiorectal fossa in a 55-year-old man presenting with a painful mass on the buttocks. Hair and fatty components were obtained by targeted ultrasound-guided biopsy. On MR imaging, the mass was seen to be well circumscribed and registered a heterogeneous T1-weighted signal that corresponded to layers of fat and debris on short-tau inversion recovery (STIR) imaging. A well-defined ball of fat was noted centrally within the lesion, with a speckled low T1 and low T2 signal within it. Hair admixed with fat was obtained from it by targeted ultrasound-guided biopsy. There was no enhancement of the lesion after administration of gadolinium. On ultrasound, the lesion was well circumscribed and heterogeneous; the echogenic area corresponded to the fat signal seen on magnetic resonance imaging (MRI). The lower level echoes within the lesion corresponded to the debris seen on MRI. The central rounded area of speckling, registering fine posterior shadowing corresponded to the hairy contents obtained by the targeted ultrasound-guided biopsy. A differential diagnosis of all lipomatous lesions was included in the pre-biopsy report: fat necrosis within a lipoma; well-differentiated liposarcoma; myxoid liposarcoma and dermoid cyst. Histopathological diagnosis following complete surgical resection was that of a dermoid cyst. (orig.)

    Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly. PMID:28210514

    Echinococcosis is a cyclozoonosis characterized by cystic lesions usually situated inside or outside the liver. We discuss the case of a 77-year-old woman with a recurrent hydatidosis with a cyst arising from the liver, growing through the lateral right abdomen wall, and reaching the subcutaneous tissue of the lumbar region. In the literature, rare subcutaneous or muscular localizations of hydatid cysts are described, however, there is no mention of a cyst growing over the abdominal wall muscles, shaped like an hourglass, partially in the liver and partially in the subcutaneous tissue, as in our case.We have not found any pathogenetic explanation for this growth pattern which is not typical of the biological behaviour of a hydatid cyst.

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

    Four perineurial cysts cases (Tarlov's cysts) are reported. The purpose of this study is to describe and to compare them with data from a literature review. The evaluation was performed among 88 adult patients with symptoms of radiculopathy, sacral pain, low back pain. Four patients revealed Tarlov's cysts (4.5%). The diagnosis was made by magnetic resonance imaging. Four cases underwent sacral laminectomy. Following surgery, the claudication pain resolved with no motor or sensory deficits. Tarlov's cysts should be considered as a differential diagnosis of sacral radiculopathy, sacral or lumbar pain syndromes and mainly to the lumbar disc prolapse. The goal of the surgical treatment is to relieve the neural compression and stop bone erosion.

    The purpose of this study was to investigate the surgical outcomes and to determine indicators of the necessity of surgical intervention. Twelve consecutive patients harboring symptomatic sacral perineural cysts were treated between 1995 and 2003. All patients were assessed for neurological deficits and pain by neurological examination. Magnetic resonance of imaging, computerized tomography, and myelography were performed to detect signs of delayed filling of the cysts. We performed a release of the valve and imbrication of the sacral cysts with laminectomies in 8 cases or recapping laminectomies in 4 cases. After surgery, symptoms improved in 10 (83%) of 12 patients, with an average follow-up of 27 months. Ten patients had sacral perineural cysts with signs of positive filling defect. Two (17%) of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes.

    The hydatid cyst of kidney is rare, it ranks third among all visceral localisations. The authors report a series of 90 cases renal hydatid cyst from 1972 to 2000. The middle age is 36 years with female predominance. Renal hydatid cyst often has a suggestive clinical presentation; flank mass in 84%, pain in 74% and sometimes a specific presentation hydaturia in 29%. The hydatid serology is positive in 55% and preferring ultrasonography and computed tomography in diagnosis of renal hydatid cyst. Surgical treatment is now well defined. Conservative treatment occupes a predominant place 84% and resection of the proeminent dome is usually efficient. Total nephrectomy should only be considered in the case of a completely destroyed kidney (16%) of cases. Post-operative course is generally uneventful and reexpansion of renal parenchyma is observed in 93% indicating the benign nature of this disease.

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    Full Text Available INTRODUCTION: The nasolabial cyst is classified in the group of non-odontogenic epithelial developmental cysts. Their occurrence is rare, however, they are located in the nasolabial sulcus, close to the alar insertion in the nose, external to the maxillary bone tissue. It is characterized as a floating tumor, generally asymptomatic, which promotes elevation on the nasal ala. OBJECTIVE: To report a case of nasolabial cyst addressing clinical, histopathological and radiological aspects, in order to alert professionals as regards their responsibility in diagnosis. MATERIAL AND METHOD: Female patient with a swelling in the region of the upper lip and nasal ala. After clinical examination, radiographic examination, puncture and aspiration, total surgical enucleation of the cyst was performed and the material collected was sent for histopathologic analysis. CONCLUSION: the dentist must be alert in order to make an early diagnosis, because it is not uncommon to overlook the lesion in the early stages.

One of the commonest problems after putting the VP shunt is the shunt obstruction, which can be due to varied causes. Shunt obstruction secondary to the parasitic infections is rarely seen. We are presenting a 15-year-old child, a case of operated cerebral hydatid cyst with hydrocephalus. She presented with shunt malfunction after 1 year of surgical excision of the hydatid cyst. Revision of the VP shunt was done and peroperatively, it was found that the shunt tubing was obstructed due to small hydatid cysts. This is the first reported case of VP shunt obstruction by hydatid cyst.

    Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up. PMID:27547744

    Full Text Available Among all the possible complications of aesthetic rhinoplasty, a rare one is the development of cystic masses on the nasal dorsum: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients had undergone aesthetic rhinoplasty in the past (26 years ago and 14 years ago, resp.. Both cystic masses were removed via a direct open approach and nasal reconstruction was performed successfully with autologous vomer bone. The pathologic investigations showed a foreign body inclusion cyst associated with latex rubber in the first case and a sequestration of a mucosal-lined nasal bone was not removed at the time of primary rhinoplasty in the second case. A brief review of the literature focuses on the pathophysiology and treatment options for nasal dorsal cysts following aesthetic rhinoplasty.

    An air-filled paratracheal cyst is a common radiological finding. It may be a congenital defect or an acquired lesion. 'Acquired paratracheal cyst' is the term given to the acquired abnormalities, which usually arise in adults. They result from a weakness of the tracheal wall, and they may be caused by trauma, infection, high pressure injuries, long lasting tracheostomy, and obstructive tracheal disease. Majority of the paratracheal air cysts are asymptomatic and are discovered incidentally on radiological images. Also, the management is primarily conservative treatment. Here, we report a case of an infected paratracheal air cyst on the right posterolateral wall of the trachea, which developed into an abscess and was visualized on follow-up multidetector computed tomography and was surgically removed due to persistent symptoms.

    Chondroblastoma is a benign tumor that typically arises in the epiphysis of a long bone. There have been only 2 reported cases of chondroblastoma involving the capitate. This is the first report of chondroblastoma with secondary aneurysmal bone cyst involving the capitate. A 33-year-old man presented with a 3-year history of pain and swelling of the right wrist. Radiography as well as computed tomography showed a radiolucent area and no matrix calcification within the capitate. Magnetic resonance imaging revealed a homogeneous signal that was low on T1-weighted images and high on T2-weighted images and showed only slight enhancement. On the basis of imaging findings, the authors chose excisional biopsy. The bone tumor in the capitate was explored through a dorsal approach by dividing the extensor tendons. After repeated curettages, bone graft substitute using allograft bone was packed into the capitate. Histologically, the authors diagnosed this tumor as a chondroblastoma with a secondary aneurysmal bone cyst. At the final 2-year follow-up, there was evidence of bone union, full range of motion, and recovery and no evidence of recurrence. Although the recurrence of chondroblastoma is occasionally reported, the principal treatment is intralesional curettage and bone graft. High-speed burring, phenol, bone cement, and cryosurgery have been reported to reduce local recurrence. Complete excision of the carpal bone seems to be overtreatment.

    Cysts arising in the penis are uncommon and can be found anywhere from the urethral meatus to the root of the penis involving glans, foreskin, or shaft. Median raphe cysts account for the majority of penile cystic lesions reported in the literature. As their name suggests, they arise on the ventral midline of the penis that extends from the urethral meatus to the scrotum and perineum. Proposed hypotheses for their origin as well as their diverse morphology are discussed.

    Full Text Available Epidermal inclusion cysts are uncommon in the breast, but the consequences can besevere when these cysts occur in the breast parenchyma. Here,we report two suchcases. The patient in case 1 was an 37-year-old woman with a 3-cm palpable mass inthe right breast. Mammography revealed a round and smoothly outlined mass, whichindicated a benign tumor, and sonography showed an irregularly shaped and heterogeneoushypoechoic mass, fibroadenoma was suspected on the basis of clinical andimage findings, but excisional biopsy revealed an epidermal inclusion cyst. The patientin case 2 was a 50-year-old woman with a 2.5-cm lesion in the left breast. Mammographyrevealed a round, dense, smoothly outlined mass, and sonography showeda well-defined, central hyperechoic mass. . Breast cancer was suspected on the basisof the sonographic findings and the age of the patient, but the resected specimen revealedan epidermal inclusion cyst. Although epidermal inclusion cysts are benign,occasionally they may play a role in the origin of squamous carcinoma of the breast. .Mammographic and sonographic features of an epidermal cyst may mimic a malignantlesion. Malignant change appears to occur more frequently in epidermal inclusioncysts in the mammary gland, compared to common epidermal inclusion cysts,and this may be associated with origination of mammary epidermal inclusion cystsfrom squamous metaplasia of the mammary duct epithelium.Epidermmoid inclusion cyst of the breast is potentially serious, although such cystsare rare, and differentiation from a malignant or benign breast tumor is required. Excisionis probably the most appropriate treatment, and can eliminate the possible riskof malignant transformation.

    Dentigerous cysts form from accumulation of fluid between reduced enamel epithelium and the crown of an unerupted tooth. They cause several difficulties such as swelling, non-eruption of the involved teeth, and displacement of adjacent teeth, and thus require early detection and prompt treatment. Treatment ranges from marsupialisation to enucleation. Enucleation is rarely used in children compared with marsupialisation. This paper discusses successful use of enucleation for treating a dentigerous cyst and explains the need for such a radical procedure.

    The testicular epidermoid cyst is an uncommon benign tumor that represents 1% to 2% of resected testicular masses. The observation of the characteristic ultrasonographic features of these lesions facilitates their diagnosis and may make it possible to perform enucleation, obviating the need for orchidectomy. We present two cases in which the testicular epidermoid cysts were diagnosed preoperatively and their presence confirmed after conservative surgery. We review the literature concerning imaging studies and the management of these lesions. (Author) 9 refs.

They can produce the compression of the mediastinal structures typically caused the symptoms of dyspnea, thoracic pain, tachicardia and cough due to the unusual large size of the cyst. It can performed symptoms of lung atelectasia. The case was a sixty-five years old woman followed with a diagnosis of COPD for seven years. The patient was admitted to our center with the diagnosis of elevation of the right hemidiaphragm on chest radiography. The computed tomography revealed a cystic lesion adjacent to the right hemidiaphragm and cyst excision was performed via right thoracotomy. Patient%u2019s postoperative clinical findings indicated that the symptoms of COPD regressed completely and the patient did not require any further bronchodilator therapy. The aim of this case report is to demonstrate that the pericardial cysts can be missed in chest radiographs and impression of cysts may cause COPD like symptoms in these patients.

    Full Text Available Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer′s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease. In regions where hydatidosis is endemic, hydatid cyst should be included in the differential diagnosis of any unusual muscular mass.

    Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg. There was no recent history of spine or pelvic trauma. These symptoms prompted her initial emergency department evaluation, and imaging demonstrated a large Tarlov cyst with an associated sacral insufficiency fracture. She was noted to have a normal neurological examination notable only for an antalgic gait. She was taken to surgery via a posterior approach and the cyst was identified eccentric to the left. The cyst was fenestrated and the nerve roots identified. Given her large area of bone erosion and insufficiency fractures, fixation of the sacroiliac joints was deemed necessary. Fusion was extended to the L5 vertebral body to buttress the fixation. She tolerated the procedure well and was discharged from the hospital on postoperative day 3. Tarlov cysts of the sacrum can lead to significant bone erosion and subsequent insufficiency fractures, requiring fenestration and in some cases, complex sacropelvic fixation.

    In a grid investigation, dinoflagellate cysts were collected from sediments in Xiamen Western Harbor in May of 2000,from which five species of cysts were identified: Alexandrium tamarensis, A. minutum, Lingulodinium polyedra,Gonyaulax scrippsae and Gymnodinium catenatum, account for about 21% in the species composition. The quantitative analysis of the sediments shows that the number of dinoflagellate cysts varies from 51 to 256 cysts/g of sediment, the highest value (>200 cysts/g) being recorded at the stations of the central part of the bay, while the lowest (<100 cysts/g) at the bay mouth. A good linear relationship is found between cyst amount and fine-grained sediments. Complex physiognomies on the seabed, topographty in the bay and weak water exchange are the main factors not only in cyst accumulation but also in their distribution pattern, and have resulted in the difference in cyst densities between the inner bay and the outer bay in the harbor.

    2009-01-01

    BACKGROUND: Choledochal cysts are classiifed into ifve types based on the location of the cyst. Mixed types of choledochal cysts are extremely rare. Only ifve cases of mixed typeⅠ andⅡ choledochal cysts have been reported, of which one was an adult case. We report a mixed typeⅠandⅡ choledochal cyst in a 25-year-old man. METHODS: The unusual nature of the choledochal cyst, suspected on magnetic resonance cholangiopancreatography RCP to be typeⅠ initially, was conifrmed by laparotomy to be a mixed typeⅠ+Ⅱ cyst. Excision of the cyst and hepaticojejunostomy were performed. RESULT: The operation was uneventful, and the patient recovered well. CONCLUSIONS: Mixed type choledochal cysts are rare, and may be missed on imaging, unless careful evaluation is done. The operative method may not need to be modiifed signiifcantly, as in the management of our case.

  20. The diagnosis and management of synovial cysts: Efficacy of surgery versus cyst aspiration.

    2012-01-01

    The surgical management of lumbar synovial cysts that have extruded into the spinal canal remains controversial (e.g. decompression with/without fusion). The neurological presentation, anatomy, pathophysiology, and surgical challenges posed by synovial cysts in the lumbar spine are well known. Neurological complaints typically include unilateral or, more rarely, bilateral radicular complaints, and/or cauda equina syndromes. Anatomically, synovial cysts constitute cystic dilatations of synovial sheaths that directly extrude from facet joints into the spinal canal. Pathophysiologically, these cysts reflect disruption of the facet joints often with accompanying instability, and potentially compromise both the cephalad and caudad nerve roots. Aspiration of lumbar synovial cysts, which are typically gelatinous and non-aspirable, and typically performed by "pain specialists" (e.g. pain management, rehabilitation, radiologists, others) utilizing fluoroscopy or CT-guided aspiration, is associated with 50-100% failure rates. Surgical decompression with/without fusion (as the issue regarding fusion remains unsettled) results in the resolution of back and radicular pain in 91.6-92.5% and 91.1-91.9% of cases, respectively. After a thorough review of the literature, it appears that the treatment with the best outcome for patients with synovial cysts is cyst removal utilizing surgical decompression; the need for attendant fusion remains unsettled. The use of an alternative treatment, percutaneous aspiration of cysts, appears to have a much higher recurrence and failure rate, but may be followed by surgery if warranted.

    Palatal cysts are always confusing by deifning their exact nomenclature or conclusive diagnosis. One of these presentations is globulomaxillary cyst which requires to be categorized under appropriate head for the management point of view. Though this entity appears to be of odontogenic in origin but because of its anatomical relation and histo-pathological background this is placed in non odontogenic group. Though the mechanism of its formation remains the same but this cyst cannot be mixed up with nasopalatine cyst as per their location. Globulomaxillary cyst appears as inverted pear shaped radiolucency in all radiological procedures. This remains asymptomatic for a long time and rarely gets infected. We present a 29-year-old male who reported with one year history of asymptomatic right side hard palate swelling. He was subsequently diagnosed as globulomaxillary cyst with the help of radiological modalities like computerized tomography and magnetic resonance imaging. This article will highlight mainly the clinical and radiological features of these cysts with particular reference to globulomaxillary cyst which is our presenting case.

    Synovial cysts at the atlantoaxial level are found uncommonly. Lumbar symptomatic cases are treated by percutaneous cyst aspiration with or without corticoid injection or by surgical resection, but synovial cysts at the C1-C2 level are usually treated by surgery. We report here a 92-year-old woman with a retro-odontoid synovial cyst producing spinal cord compression that was treated by percutaneous aspiration of the cyst under CT guidance. To our knowledge, this is the first reported case of an atlantoaxial synovial cyst successfully treated with a minimally invasive procedure.

    Full Text Available Paraurethral or Skene′s duct cysts are rare causes of interlabial masses in neonates. The diagnosis of Skene′s duct cysts in the neonatal period is based on its location, in relation to the urethra, and the demonstration of transitional epithelium in the cyst wall. The distinguishing features of paraurethral cysts are the displacement of urethral meatus by the mass and a cyst containing milky fluid. Thus, we report a case of a Skene′s duct cyst in a newborn which was treated by incision and drainage.

    Choledochal cysts are rare. They usually present during childhood in women, but it can also be seen during pregnancy. Clinical signs and symptoms are obscured during this time, thus it can complicate the diagnosis and represent a life threatening complication for both the mother and the child. To communicate the case of 3 pregnant patients with choledochal cyst. Three pregnant women in which choledochal cyst were diagnosed. Two developed signs of cholangitis. The first one underwent a hepatic-jejunostomy, but had an abortion and died on postoperative day 10. The second one had a preterm caesarean operation due to foetal distress and underwent a hepatic-jejunostomy 4 weeks later; during her recovery she had a gastric perforation and died of septic complications. The third one did not develop cholangitis or jaundice. She had an uneventful pregnancy and had a hepatic-jejunostomy 4 weeks later with good results. Management of choledochal cysts during pregnancy is related to the presence of cholangitis. When they do not respond to medical treatment, decompression of the biliary tree is indicated. Definitive treatment should be performed after resolution of the pregnancy. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    Full Text Available We report two unusual cases of a 17-month-old boy with a previously undiagnosed lumbar dermal sinus tract terminating in an intradural dermoid cyst and holocord edema or syrinx, presenting with paraparesis and sphincter dysfunction secondary to an intramedullary abscess and a 26-month-old boy with a previously undiagnosed lumbar dermal sinus tract terminating in an infected dermoid cyst and intramedullary abscess, presenting with recurrent episodes of meningitis and hydrocephalus. Pre-operative magnetic resonance imaging (MRI studies in these patients were initially confused for an intramedullary spinal cord tumor; however, the presence of an associated dermal sinus tract made this diagnosis of neoplasm less likely. Total excision of the dermal sinus tract, debulking of the dermoid cyst and drainage of the intramedullary abscess through an L1-L5 osteoplastic laminoplasty and midline myelotomy, followed by long-term antibiotic therapy resulted in a good functional recovery. Post-operative MRI of the spine showed removal of the dermoid cyst, decreased inflammatory granulation tissue and resolution of the holocord edema or syrinx. We also performed a literature review to determine the cumulative experience of management of intramedullary abscess in this rare clinical setting.

    Acanthamoeba castellanii, a free-living amoeba, causes a sight-threatening form of keratitis. Even after extensive therapies, corneal damage can be severe, often requiring corneal transplantation to restore vision. However, A. castellanii cysts are not eliminated from the conjunctiva and stroma of humans and can excyst, resulting in infection of the corneal transplant. The aim of this study was to determine whether elements of the innate immune apparatus, neutrophils and macrophages, were capable of detecting and eliminating A. castellanii cysts and to examine the mechanism by which they kill the cysts. Results show that neither innate immune cell is attracted chemotactically to intact cysts, yet both were attracted to lysed cysts. Both macrophages and neutrophils were capable of killing significant numbers of cysts, yet neutrophils were 3-fold more efficient than macrophages. Activation of macrophages with lipopolysaccharide and interferon-gamma did not increase their cytolytic ability. Conditioned medium isolated from macrophages did not lyse the cysts; however, prevention of phagocytosis by cytochalasin D inhibited 100% of macrophage-mediated killing of the cysts. Conditioned medium from neutrophils did kill significant numbers of the cysts, and this killing was blocked by quercetin, a potent inhibitor of myeloperoxidase (MPO). These results indicate that neither macrophages nor neutrophils are chemoattracted to intact cysts, yet both are capable of killing the cysts. Macrophages killed the cysts by phagocytosis, whereas neutrophils killed cysts through the secretion of MPO.

    2003-01-01

    Full Text Available In the present study, the performance of Immunomagnetic Separation technique, coupled with Immunofluorescence (IMS-IFA, was compared with the FAUST et al. and Lutz parasitological techniques for the detection of Giardia lamblia cysts in human feces. One hundred and twenty-seven samples were evaluated by the three techniques at the same time showing a rate of cyst detection of 27.5% by IMS-IFA and 15.7% by both Faust et al. and Lutz techniques. Data analysis showed a higher sensitivity of IMS-IFA for the detection of G. lamblia cysts in comparison with the techniques of FAUST et al. and Lutz. The use of this methodology as a routine procedure enables the processing of many samples simultaneously, in order to increase recovery rate of G. lamblia cysts and reduce the time of sample storage.

    Synovial cysts of the spine occur most frequently in the lumbosacral region. Methods of treatment vary, but in cases of chronic pain or neurological deficits surgical intervention is undertaken. The aim of this paper is to present indications, surgical technique and efficacy of surgical treatment in patients with synovial cyst of the spinal canal. The retrospective analysis included 11 patients, aged from 47 to 72 years, treated at the Department of Neurosurgery and Neurotraumatology, Poznan University of Medical Sciences, between 2004 and 2009. The length of medical history ranged from 2 months to 6 years. Conservative treatment applied before surgery was not effective. Neurological examination revealed unilateral or bilateral sciatica, superficial sensory disturbance or lower limb paresis. Synovial cysts were located mainly at the L4-L5 level (9 cases). Magnetic resonance imaging (MRI) of the spine was performed in all patients and showed the cystic lesion attached to the intervertebral joint. Surgical treatment consisted of a unilateral fenestration using microsurgical techniques in most cases. Back pain relief was observed in 9 cases. In 10 patients, symptoms of sciatica disappeared. Neurological deficits disappeared in 5 patients. Surgical treatment of spinal synovial cysts is safe, effective and ensures a long-lasting effect. Surgical treatment is indicated in patients in whom the clinical symptoms correlate with the presence of synovial cyst in imaging studies and do not resolve after conservative treatment.

    A 5-year-old neutered male domestic shorthair cat was presented for examination of a subcutaneous mass in his tail. The mass was firm, non-painful, oval, and approximately 2.5 × 3.5 cm. Surgical exploration revealed a well-circumscribed, encapsulated mass. The mass was removed and sectioned for histopathological examination. In gross section, it was filled with numerous dark hairs. Histologically the mass was consisted of haired skin with dermal cystic structures lined by stratified squamous epithelium. The cyst lumen contained squamous debris and filled with keratinous material. Numerous hair shafts were extended from the wall of the cyst. The sebaceous and apocrine gland adnexal structures were also observed which confirmed the diagnosis of dermoid cyst. No tumor recurrence was observed after surgery in fallowing checkups. Cutaneous or subcutaneous cysts of all types are considered rare in cats and to our knowledge this is the third reported case of cutaneous dermoid cyst of cats in veterinary literature which is different from the other cases because it occurred in dorsal midline in tail area whereas others occurred in flank area.

    Full Text Available The purpose of this study is to describe transient macular cysts in an infant and correlate their occurrence with normal development events. A newborn Caucasian girl presented with a protruding corneal mass in her left eye at birth. She underwent a complete ophthalmic examination. A keratinized staphylomatous malformation involving the entire cornea and precluding further visualization of the anterior and posterior segment was observed in the left eye. Spectral domain optical coherence tomography (SD-OCT of the right eye performed when the child was approximately 6-week-old had revealed an unexpected finding of macular cysts involving the inner nuclear and outer retinal layers. Corneal transplant in the left eye was performed a month later. Ocular examination under anesthesia just prior to surgery revealed normal intraocular pressure, anterior segment and retina in the right eye. SD-OCT was normal in both eyes and showed complete resolution of the cysts in the right eye. The patient had not been on any medications at that time. Although clinical retinal examination might be unremarkable, SD-OCT may reveal cystic spaces in the macula. In the absence of conditions known to be associated with macular edema, transient macular cysts may arise due to a developmental incompetence of the blood-retinal barrier or may represent transient spaces created during normal migration of retinal cells. Further study is warranted to delineate the entity of transient macular cysts in infancy.

    We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts) are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

    2014-07-01

    Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts. Endoscopic ultrasound (EUS) has been widely used as a modality for the evaluation and diagnosis of duplication cysts. EUS is the diagnostic tool of choice to investigate duplication cysts since it can distinguish between solid and cystic lesions. The question of whether or not to perform EUS-fine needle aspiration (EUS-FNA) on a lesion suspected of being a duplication cyst is controversial as these lesions can become infected with significant consequences, although EUS-FNA is often required to obtain a definitive diagnosis and to rule out more ominous lesions. This manuscript will review the literature on duplication cysts throughout the body and will also focus on the role of EUS and FNA with regards to these lesions.

    Seemingly intact cysts and sequential stages of disintegrating cysts of Toxoplasma were identified immunohistologically within developing microglial nodules in a Panamanian night monkey (Aotus lemurinus). This monkey had been successfully immunized and challenged 5 months earlier. This supports the hypothesis that glial nodules unassociated with Toxoplasma tachyzoites may represent the tombstone of a Toxoplasma cyst. Disintegration of cysts may give rise to clinical encephalitis in the presence of apparently adequate immunity.

    Mesiodens, the most common type of supernumerary tooth, usually results in malocclusion, poor esthetics and cyst formation. The occurrence of a dentigerous cyst around the crown of an unerupted supernumerary tooth is infrequent. We present a case of a dentigerous cyst associated with a nonsyndromic bilateral impacted inverted supernumerary tooth in a 13-year-old boy. A thorough clinical workup, including 3-D reconstruction image and histological examination confirming the features of a dentigerous cyst is presented in this report.

    Meniscal cysts are a rare disease constantly combined with a horizontal meniscal lesion. Currently, nuclear magnetic resonance (MRI) is the main diagnostic tool, because of its high sensitivity and specificity, and decompression arthroscopy combined with selective meniscectomy is the treatment of choice. The Authors report a case of a voluminous medial meniscal cyst where instrumental examination, MRI, was fundamental for the preoperative diagnosis of the horizontal meniscal lesion causing the cystic degeneration of the meniscus. The treatment performed was selective meniscectomy of the body and posterior horn of the medial meniscus and decompression of the voluminous cyst by arthroscopy. Physical examination after six months showed the complete resolution of swelling at the medial hemirima, no walking pain and normal range of motion.

    Full Text Available Postoperative maxillary cyst is a quite rare delayed complication of surgical intervention associated with maxillary sinuses. It occurs many years after surgery. This paper describes a 54-year-old woman presenting with swelling of left cheek for seven-years duration. The orthopantomograph revealed a unilocular cystic radiolucency with well-defined margins in left maxillary sinus. In the computerized tomography, the cyst had a sclerotic wall with bony condensations. Aspiration cytology revealed many neutrophil leukocytes. Cyst was drained and enucleated. Histopathologically, it had a fibrous wall with inflammation and focal reactive bone formation and lined by a respiratory-type epithelium. In the clinical history, it is learned that she had a maxillary sinus surgery 8 years ago and the diagnosis was made considering the clinical and histopathological findings.

    Full Text Available Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50 mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

    Full Text Available If a pediatric abdominal mass is not organomegaly or colonic stool, narrowing the diagnostic possibilities may be difficult, especially in resource-poor areas where ancillary tests and treatment options may be limited. A 2-year-old girl was brought to the rural Kintampo Municipal Hospital in Ghana with a freely moveable, non-tender abdominal mass. A huge mesenteric dermoid cyst was surgically removed. Mesenteric cysts are rare intra-abdominal lesions, most commonly occurring in children < 10 years old. Making a preoperative diagnosis is difficult. Dermoid cysts (mature cystic teratoma rarely occur in the mesentery. Poverty, family circumstances and the rural location led to general physicians doing surgery. As in this case, due to economic, social and transportation issues common throughout Africa, children with abdominal masses may need at least initial surgery in hospitals without dedicated pediatric surgery or even a trained surgeon.

    Full Text Available Background. Hepatic hydatid cyst infection is caused by microorganisms named Echinococcus which belong to family Taeniidae. Platelets are considered as a mediator in inflammation and infectious diseases because of the various proinflammatory substances that they contain. Design and Methods. Thirty-three patients who were admitted to Doğubayazıt State Hospital’s General Surgery Clinic with a diagnosis of hepatic cyst hydatid were enrolled in this retrospective study. Laboratory data of the patients in pre- and postoperative periods were obtained from computerized medical records database of the hospital. Results. Preoperative mean platelet volume (MPV of the patients was significantly increased compared to postoperative MPV values. Conclusion. We claim that MPV is a useful follow-up marker after surgery in patients with hydatid cyst.

    2015-09-01

    Full Text Available Hydatid cyst is especially prevalent in parts of Eurasia, north and east Africa, Australia, South America. Hydatid disease is a zoonotic infection caused by adult or larval stages of the cestode Echinococcus granulosus and affects both humans and mammals. The infection is transmitted to dogs when they are fed on infected viscera of sheep or other ruminant during the home slaughter of animals. In the present case series four cases of hydatid cyst occurring at the lung and liver sites are discussed. The symptoms and signs may be caused by a toxic reaction to the parasite or by local and mechanical effects, depending on the location and nature of the cysts and the presence of complications. Early diagnosis and proper treatment will help to reduce the complication rate and prevent recurrence.

    Full Text Available The objective of this study was to describe a case of a lymphoepithelial cyst in the palatoglossus arch. A 16-years-old black man said that he was observed a lesion in his mouth. On the physical exam, a pedicled, consistent, smooth surface 1.5 x 1 cm lesion, similar in color to the adjacent mucosa, was found. The lesion was surgically removed and the microscopic exam showed mucosal fragments with pedicled lesion; the cystic cavity sometimes lined with pseudostratified cylindrical epithelium and others with stratified squamous flat interface of the epithelium. Around the cyst, a well-delimited mass of lymphoid tissue, presenting lymphoid follicles, was also seen. Lymphoepithelial cyst has clinical characteristics similar to those of others lesions that occur in the oral cavity. The diagnosis should be based on conservative biopsy, with total removal of lesion.

    Full Text Available Hydatidosis due to Echinococcus granulosus is an endemic parasitic zoonosis characterized by worldwide distribution particularly in Mediterranean countries. The most commonly involved anatomical locations are the liver and lung. Occasionally the cyst may progressively increase in size, mimicking gross ascites or intrabdominal tumor. Herein, are reported a case of a 40-year-old patient with a giant exophytically expanded hepatic echinococcus cyst, misdiagnosed as an abdominal malignancy during formal investigation. The patient was admitted to the hospital complaining for mild diffuse abdominal tenderness, moderate abdominal pain, nausea, diarrhoea, and vomiting. A CT scan revealed the presence of a giant abdominal mass 25×21×14 cm, resembling a tumor, adherent to the liver edges and parietal peritoneum, displacing intestinal loops. During the ensuing days the patient’s clinical condition worsened, and he became febrile. Exploratory laparotomy was performed, and an exophytically grown giant liver hydatid cyst was removed, despite the radiological findings and the preoperative clinical suspicion.

    A case of phaeohyphomycosis is reported in a male renal transplant recipient with a nodular lesion in the right leg who was treated with immunosuppressing drugs. The lesion consisted of a purulent cyst with thick walls. The cyst was excised surgically, and the patient did not receive any antifungal therapy. One year later he remains well. Histological study of the lesion showed a granulomatous reaction of epithelioid and multinucleate giant cells, with a central area of necrosis and pus. Fontana-Masson staining demonstrated the presence of pigmented hyphal elements. The fungus Colletotrichum crassipes was grown in different cultures from the cyst. The in vitro inhibitory activities of eight antifungal drugs against the isolate were tested. Clotrimazole and UR-9825 were the most active drugs. This case represents the first known reported infection caused by this rare species. PMID:11376082

    Full Text Available Increased radiological tests have facilitated the discovery of kidney cysts, which sometimes do not meet clear criteria for benignity or malignancy. Among these lesions, the hyperdense cysts pose a challenge to all those responsible for their diagnosis and treatment. For such reasons we decided to present the case of a 23-year-old female patient with a history of sickle cell anemia, who attended the emergency department of the Dr. Gustavo Aldereguía Lima University General Hospital due to colic-like pain in the left lumbar region unresponsive to analgesics. She was diagnosed with category II renal cyst according to Bosniak classification using computed tomography with and without intravenous contrast.

A case of intrathyroidal PC is being reported here in a 53-year-old woman who presented to the endocrine clinic with slowly progressive painless left anterior neck swelling for 1 year with no symptoms of thyroid or parathyroid dysfunction and no compressive symptoms. Ultrasound of the thyroid showed a well-defined cystic lesion measuring 4.7 × 3.6 cm in maximum diameter with internal echoes within the cyst located in the left lobe of the thyroid gland. Fine needle aspiration revealed colorless clear fluid with a high concentration of parathyroid hormone. The patient underwent left hemithyroidectomy at her request. Histopathology revealed parathyroid tissue with unilocular cyst and thyroid tissue with goitrous changes. She was in remission, and there was no evidence of thyroid or parathyroid dysfunction after surgery.

    Dermoid cysts into ENT zone are specially infrequent--just the 7% of the organism--, and extremely rare if are located in the tongue. They are usually detected as midline acute swelling, and produce swallowing, speech and sleep disorders at neonatal period because of their congenital character. We present an eleven-year-old boy admitted at our Hospital bearing a submandibular and oral swelling, and dysphagia with odynophagia, finally diagnosed as an intralingual double dermoid cyst of the anterior two thirds. The history of frenulectomy due to a presumed ankyloglossia, the previous presence of a dorsal tumour in tongue with a difficult phonetic articulation, and the midline location of lesions made us to suspect on dermoid cysts of the tongue. Complete surgical excision were diagnostic and therapeutic, and the child recovered totally their mastication, swallowing and speech abilities. Pathophysiological aspects, treatment and the atypical course of the case are discussed.
