    Full Text Available The purpose of our study is to emphasize on the clinical relevance of the presence of accessory spleen. It is not only a well-documented anatomic anomaly, it holds special significance in the differential diagnosis of intra-abdominal tumours and lymphadenopathy. MATERIALS AND METHODS Thirty male cadavers from North Indian population above the age of 60 yrs. were dissected in the Anatomy Department of FMHS, SGT University, Gurgaon, over a period of 5 yrs. (Sep 2010-Aug 2015 and presence of accessory spleen recorded. Tissue from the accessory spleen was also subjected to routine histological processing and slide prepared by haematoxylin and eosin staining. RESULTS Accessory spleen was present in two cadavers near the splenic hilum. One was 3.9 cm in the long axis and weighed about 48.4 grams, while the other was 1.2 cm in long axis and weighed about 12.5 grams. One had a separate arterial branch from the main splenic artery; that it was splenic tissue was confirmed histologically. DISCUSSION The presence of accessory spleen is considered to be due to embryonic non-fusion of the splenic aggregate with the main mass. CONCLUSION Though accessory spleen in itself pose no clinical problems, its significance cannot be undermined. Surgeons and radiologists are advised to look for and rule out the presence of accessory spleen, especially while evaluating a case of abdominal and perineal pathology, else it may be wrongly diagnosed as malignant tumour or enlarged lymph node leading to grave consequences.

    2014-01-01

    Accessory breast tissue is an uncommon condition which occurs in 0.4-6% of women. It is mostly located in the axilla where it can cause diagnostic difficulty, especially if it is unilateral and large. Usually it is bilateral and presents as an asymptomatic mass during pregnancy or lactation. The diagnosis of ectopic breast tissue is important as it can undergo the same pathological changes that occur in a normal breast, such as mastitis, fibrocystic disease and carcinoma. We present a case of a large right-sided accessory breast in a 32-year-old woman that was clinically diagnosed as pedunculated lipoma. However, subsequent histopathological examination proved it to be an accessory breast tissue with lactational changes. PMID:25006058

  4. Role of nuclear medicine imaging in differential diagnosis of accessory spleens in patients after splenectomy

    More than 10% of healthy population has one or more accessory spleens. The most common location is the hilum of the spleen or area near the tail of the pancreas. The radiological appearance of accessory spleens in oncologic patients who underwent splenectomy can be misinterpreted as a recurrence, especially in the case of compensatory growth of an accessory spleen in successive radiological examinations. We present the cases of three patients who underwent splenectomy for gastric carcinoid, gastric adenocarcinoma and cancer of the left adrenal gland, respectively. CT examination and/or PET-CT scan revealed suspicious findings in the left upper abdomen. In one patient, the dimensional increase of this finding in successive examinations was initially considered suggestive for cancer recurrence. Scintigraphy with 99mTc-nanocolloid was able to confirm the presence of an accessory spleen in all these patients. Splenic scintigraphy is an economical, accessible and accurate tool in differential diagnosis of accessory spleens in patients after splenectomy

    2016-12-01

    We report the case of a 60-year-old man with an accessory spleen in the pelvis. He visited our outpatient clinic because of abdominal discomfort. Computed tomography (CT) showed an enhanced mass (40 mm in diameter) in the pelvis. Preoperative diagnosis was difficult even after magnetic resonance imaging and colonoscopy. The patient underwent surgery for suspicion of a gastrointestinal stromal tumor or malignant lymphoma of the rectum. Intraoperative findings showed a mass in the pelvis and a long cord-like tissue reaching the mass and arising from the great omentum; the mass was excised. Histopathologic examination indicated that the mass was splenic tissue, and feeding vessels were found in the cord-like tissue, which were determined to be derived from the left gastroepiploic artery and vein. Thus, we diagnosed it as an accessory spleen in the pelvis. An accessory spleen is not rare and can occur anywhere in the abdominal cavity. However, an accessory spleen in the pelvis is an infrequent finding, and only 9 other cases of an accessory spleen in the pelvis have been reported. Therefore, it is very difficult to make a correct diagnosis preoperatively. However, 7 of the 9 cases (77.8 %) of a pelvic accessory spleen had vascular pedicles from the great omentum or splenic hilum as feeding vessels; hence, determining the feeding blood vessels on dynamic CT may be useful for diagnosing an accessory spleen in the pelvis. Additionally, if the accessory spleen is symptomatic or has a vascular pedicle, surgeons should attempt to resect the accessory spleen in the pelvis using minimally invasive laparoscopy.

  7. Spleen

    After the liver, the spleen is the next major site of phagocytosis. This function of the spleen causes the organ to take up intravenously administered technetium-99m (Tc-99m) sulfur colloid. In addition, the spleen is the principal site for red cell sequestration. As a consequence, selective splenic imaging is possible after intravenous administration of Tc-99m heat-damaged red blood cells. Indications for splenic scintigraphy include evaluation of abdominal trauma, splenomegaly, tumors, and left upper quadrant mass; search for accessory spleen(s) and diaphragmatic eventration or herniation; and assessment of infarction, functional asplenia, polysplenia, and the heterotaxia syndrome

    2011-01-01

    An accessory navicular bone (ANB) is present in 10-30% of normal feet. A morphological classification of ANB on the basis of the radiographic appearance distinguishes three types. Most symptomatic ANBs are of type 2. Although the diagnosis and treatment of sprained ankle are generally straightforward, together with an ANB, it might be misdiagnosed as a fracture. We present a 20-year-old male with type 2 ANB who was misdiagnosed as navicular fracture following sprained ankle. Turk J Phys Med...

This occasional finding can raise difficulties in differential diagnosis with hypervascular pancreatic lesions, such as pancreatic neuroendocrine tumor. Presentation of cases: We present five cases in which a mass of the pancreatic tail was found on radiologic investigations. The first case was a young female patient who underwent a distal pancreatectomy because of a mass of the pancreatic tail misdiagnosed as a pancreatic neuroendocrine tumor due to its radiologic features on computed tomography and magnetic resonance imaging (MRI (small, ovoidal, and well defined. Misdiagnosis also occurred in the second case, in which an 82-year-old woman was referred to our hospital because of a pancreatic mass of uncertain diagnosis. She also underwent an operation, and pathologic examination showed splenic parenchyma. A correct diagnosis was achieved in the remaining three cases that are still under radiologic monitoring. Discussion: IPAS is a benign entity and therefore does not require surgical treatment. We discuss the best diagnostic options that have recently been experienced, focusing on diffusion-weighted and superparamagnetic iron oxide MRI, which in our experience seem to be the safest and most easily accessible diagnostic tools. Conclusion: We suggest that a multidisciplinary approach should guide the diagnosis. When a pancreatic mass with specific features (round, ovoid, and well defined is detected by computed tomography or MRI, an IPAS should be

    We report a very rare case of acute abdomen caused by torsion of an accessory spleen that was preoperatively diagnosed and cured by single-port surgery. A 31-year-old woman was admitted to our hospital with severe left abdominal pain. Physical examination revealed a left upper quadrant abdominal tenderness with voluntary guarding. Ultrasound demonstrated a well-defined round mass isoechoic to the spleen, measuring 3.0 cm in diameter in the left upper quadrant adjacent to the spleen. A contrast-enhanced CT scan showed a normally enhanced spleen and a 3.0 × 3.0, hypodense, non-enhancing mass anterior to the spleen with a twisted funicular structure. Torsion of an accessory spleen was suspected, and emergency single-port surgery was performed. During surgery, a rounded violet mass measuring 3.0 cm in diameter, suggestive of an accessory spleen, with a 1800° torsion around a long vascular pedicle along the left side of the greater omentum was discovered. The mass was removed and post-operative recovery was uneventful. A review of the literature revealed 26 cases (including ours) of torsion of an accessory spleen in English. Even with the recent advances in radiologic imaging modalities, making a preoperative diagnosis of this is difficult and most cases are diagnosed during laparotomy. This is the first report preoperatively diagnosed and cured by single-port surgery. We decided to start the operation by using a single port, not only for cosmetic reasons for this young female patient, but also for final confirmation of our diagnosis. We believe that single-port laparoscopy is valuable as a diagnostic tool as long as safety is assured for patients with acute abdomen. Although torsion of an accessory spleen is extremely rare, it should be considered in the differential diagnosis of acute abdomen in children and young adults. PMID:26943424

    This paper describes an investigation of the sudden and unexpected death of a five-and-a-half-month-old boy. As in every Dutch case of sudden unexpected death in infancy (SUDI), a multidisciplinary diagnostic approach was used. This included post-mortem radiography, showing a linear discontinuity of the parietal bone. Originally this was interpreted as a skull fracture, but autopsy indicated no signs of mechanical trauma. Instead the defect was defined as a unilateral accessory suture of the parietal bone. The initial erroneous diagnosis had severe adverse consequences and thus every health care professional or forensic specialist dealing with paediatric mechanical traumas should be cautious of this rare anomaly.

    Accessory breast is a rare entity that can present as asymptomatic masses or can cause symptoms like heaviness, pain, restriction of arm movement and limitation in daily pursuits with allied apprehension and anxiety for the patient. We present a case of bilateral axillary masses mimicking as accessory breast with multiple fibroadenoma in a 28 years, nulliparous, Indian woman who is HIV positive, which proves to be a diagnostic dilemma. Excisional biopsy was diagnostic. The rarity of such cases imposes challenges on the management in terms of diagnosis, prognosis and therapeutic options. PMID:23813993

  14. Accessory lobe of the liver mimicking a mass in the left adrenal gland. A case report

    An accessory lobe of the liver is a rare anomaly which we have diagnosed in a patient by CT. The lesion appeared as a soft-tissue-density mass with the same density as the liver and attached to the liver. Radionuclide liver scintigraphy helped to confirm the diagnosis. The object of this report is to draw attention to this rare entity since it can cause diagnostic confusion. (orig.)

    Hydatid cyst involving the spleen is a rare clinical condition (0.5-4%). We report a case of multi-parasitic infection in a 62 year old female (hydatid cyst and ascaris lumbricoides infestation), confirmed during surgery. The purpose of the paper is to emphasize on the rare association of the two parasitic infections, affecting two different organs (spleen and jejunum). The combined symptomatology of the two parasites could mimic an acute surgical abdomen.

    Introduction: Ectopic splenic tissues left after a previous splenectomy can masquerade as a gastro-intestinal stromal tumour (GIST). Presentation of case: Splenectomy was carried out for a 17-year-old girl with a giant epithelial cyst of spleen. Four years later, an upper endoscopy carried out for dyspepsia revealed two sub-mucosal lesions at the posterior wall of the gastric fundus. Computed tomography diagnosed a GIST. At operation, a dump-bell shaped extragastric mass was excised. Histo...

  17. Spleen: development and functional evaluation

    Despite the fact that the spleen has multiple functions, only one has been widely used for evaluation of the organ by imaging techniques (phagocytosis of /sup 99m/Tc sulfur colloid). The usual splenic uptake of this radiocolloid can by used to determine the size, location, and integrity of the organ. A major use of splenic radiocolloid imaging has been in the study of congenital defects. Thus, eventration of the diaphragm, accessory spleens, splenogonadal fusion, the asplenia and polysplenia syndromes, and the wandering spleen are amenable to study by means of intravenously administered radiocolloid. Interference with the splenic uptake of radiocolloid can be either focal or generalized (as in functional asplenia). Imaging of the spleen has a major role in evaluating suspected trauma of the organ and in following its clinical course. The return of splenic function after splenectomy (splenosis or accessory spleens) can be documented by radionuclide imaging, and likely by hematologic techniques when the volume of tissue is sufficiently large. The detection of intrasplenic lesions is important in tumor staging and as an alerting sign to an ongoing process. 96 references

  18. Wandering spleen

    2004-01-01

    Full Text Available Wandering spleen is a rare clinical entity, characterized by splenic hypermobility that results from elongation or maldevelopment of its suspensary ligaments. The wandering spleen is in constant danger of torsion and infarction. This condition poses a great diagnostic challenge due to lack of awareness and paucity of symptoms. Among adults, it usually occurs in females of childbearing age, the children below ten years of age are other sufferers. The clinical presentation may be acute or chronic; such as asymptomatic abdominal mass, an acute abdomen, or, most commonly, a mass associated with vague abdominal symptoms. Computed tomography and duplex ultrasonography are best diagnostic modalities. The traditional conservative approach carries high risk of infarction leading to splenectomy and postsplenectomy sepsis. Splenopexy is the treatment of choice for all noninfarcted wandering spleens. Splenectomy should only be performed when there is no evidence of splenic blood flow after detorsion of the spleen. The present study, reviews the presentation, course, diagnostic modalities and management options of wandering spleen

  2. Painful accessory navicular

    Lawson, J.P.; Ogden, J.A.; Sella, E.; Barwick, K.W.

    1984-11-01

    The accessory navicular is usually considered a normal anatomic and roentgenographic variant. The term may refer to two distinct patterns. First, a sesamoid bone may be present within the posterior tibial tendon (Type 1); this is anatomically separate from the navicular. Second, an accessory ossification center may be medial to the navicular (Type 2). During postnatal development this is within a cartilaginous mass that is continuous with the cartilage of the navicular. At skeletal maturity the accessory center usually fuses with the navicular to form a curvilinear bone. The Type 2 pattern may be associated with a painful foot, particularly in the athletic adolescent, and should not be arbitrarily dismissed as a roentgenologic variant in the symptomatic patient. The clinical, radiologic, pathologic, and surgical findings in ten cases are reviewed. Roentgenographically the ossicle is triangular or heartshaped. sup(99m)Tc MDP imaging may be of value when the significance of the ossicle is uncertain. Even when the roentgenographic variant is bilateral, increased radionuclide activity occurs only on the symptomatic side. Histologic examination of surgically excised specimens reveals inflammatory chondro-osseous changes in the navicular-accessory navicular synchondrosis compatible with chronic trauma and stress fracture. Nonsurgical treatment with orthotics or cast immobilization produces variable results and resection of the accessory navicular may be the treatment of choice.

    the blood was analyzed with citrate, alerting for the risk of erroneously administering blood products. CASE REPORT: This is the case of a 40-year old female patient, ASA II. In 2001 she presented with thrombocytopenia and was referred to a hematologist in Manaus, in the state of Amazonas, Brazil and underwent splenectomy that same year with a diagnosis of idiopathic thrombocytopenic purpura. Since her CBCs continued to show thrombocytopenia, an abdominal ultrasound was done and showed a spherical hypoechoic image, with an echotexture similar to the spleen, measuring 2.0 × 1.7 cm, with well-defined contents (accessory spleen, and a splenectomy was indicated. One hour into the surgery, blood samples were drawn for CBC and chemistry: Hb = 11.3 g.dL-1; Ht = 33.4%; Platelets = 35,000.µL-1; PT = 15.2 (86.0% Activity (INR = 1.09. Due to the minimal blood loss in the surgical field, a new test with citrate was requested to determine the platelet count (results: 138,000 platelets. CONCLUSIONS: The anomalous result of an isolated exam without corresponding clinical signs should not guide the treatment. All exams have a defined percentage of errors and the search for those technical errors can avoid the use of the wrong treatment.

  6. The forgotten organ: Contrast enhanced sonography of the spleen

    Objective: Ultrasound contrast agents in conjunction with contrast specific imaging techniques, are increasingly accepted in clinical use for diagnostic imaging in several organs. Contrast enhanced sonography (CES) of second-generation contrast media have shown a spleen-specific uptake of the microbubble contrast agent. The aim of this review is to illustrate indications for the use of CES in patients with suspected (peri-)splenic pathology. Methods: This review based on the experience of transcutaneous CES in 200 patients with (peri-)splenic pathology diagnosed by B-mode sonography at an internal medicine center. CES studies were performed with a contrast-devoted unit (Acuson, Sequoia, Siemens medical solution) that had contrast-specific, continuous-mode software. A low mechanical index was used. A sulfur hexafluoride-based microbubble contrast medium (Sonovue, Bracco SpA, Milan, Italy) was injected. Results: On our experience, there are several clinical conditions which may show an diagnostic advantage of CES in comparison to B-mode US. CES should be performed to investigate: (1) the perisplenic tumor to diagnose or exclude accessory spleen, (2) the small-sized spleen to diagnose functional asplenia/hyposplenia, (3) the inhomogenous spleen of unknown cause to diagnose focal lesions within the spleen, (4) the incidentally found hypoechoic splenic tumor to diagnose high vascular splenic hemangioma, (5) focal lesions suspect for splenic abscess, hematoma, infarction to confirme diagnosis, and (6) patients with abdominal trauma to diagnose or exclude splenic injuriy. Conclusion: CES is of diagnostic value in several clinical circumstances to diagnose accessory spleen, functional asplenia, small-sized splenic involvement, high vascular splenic hemangioma, and vascular splenic pathology like splenic infarction, splenic abscess, and splenic laceration

  9. Torsion of the Wandering Spleen

    Baradaran Hossein

    2009-10-01

    Full Text Available Wandering spleen, defined as a spleen without its usual peritoneal attachments, is a rare entity. We report a 34-year-old woman with acute abdomen due to torsion of the long vascular pedicle of a wandering spleen, displaced in the abdominal cavity, and infarction of the spleen. Wandering spleen was diagnosed by ultrasound and computed tomography (CT scan, and was managed by splenectomy in this patient. Wandering spleen usually occurs in 20 to 40 years old women. The most common presentation is acute abdominal pain, although signs and symptoms vary widely. Due to the risk of splenic infarction, rapid and accurate diagnosis is essential. A confirmatory diagnosis of a wandering spleen depends heavily upon imaging studies such as abdominal ultrasound, abdominal and pelvic CT scanning, nuclear scintigraphy or a liver-spleen scan. Treatment options include splenopexy or splenectomy.

  12. Spinal accessory nerve schwannomas masquerading as a fourth ventricular lesion

    Shyam Sundar Krishnan

    2015-01-01

    Full Text Available Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferiorly to the upper cervical canal. The radiological features have been detailed. The diagnostic dilemma was due to its midline posterior location mimicking a fourth ventricular lesion like medulloblastoma and ependymoma. Total excision is the ideal treatment for these tumors. A brief review of literature with tabulations of the variants has been listed.

    proteins. Together these components co‐operate in cargo‐selection as well as forming, loading and releasing budding vesicles from specific regions on the membrane surface of the ER. Coat components furthermore convey vesicle targeting towards the Golgi. However, not much is known about the mechanisms that...... regulate the COPII assembly at the vesicle bud site. This thesis provides the first regulatory mechanism of COPII assembly in relation to ER‐membrane lipid‐signal recognition by the accessory protein p125A (Sec23IP). The aim of the project was to characterize p125A function by dissecting two main domains...... in the protein; a putative lipid‐associating domain termed the DDHD domain that is defined by the four amino acid motif that gives the domain its name; and a ubiquitously found domain termed Sterile α‐motif (SAM), which is mostly associated with oligomerization and polymerization.

    Accessory breast is an ectopic breast tissue from developmental remnants. It sometimes begins to make symptom, pain and swelling, during premenstrual period or pregnancy. For it has been known as a rear condition, it has occasionally misdiagnosed as a abnormal mass, such as lymphadenitis or hidradentis. We have analyzed 52 accessory breast tissues prospectively, to document the characteristic findings of accessory breast. In summary, the characteristic sonographic findings of accessory breast were the presence of breast tissue superficial to the axillary fascia or underlying fascia if not in axilla, resembling the patient's own breast pattern, the presence of converging appearance of dilated ducts, presence of nipple and/or areola, the obliteration of inner wall of dermis, the obliteration of subcutaneous fat layer, and the downward displacement of axillary fascia or underlying fascia if not in axilla without interruption.

    Gulmann, C; Young, O.; Tolan, M.; O’Riordan, D.; Leader, M

    2003-01-01

    This report describes a rare case of chronic osteomyelitis in a 60 year old man mimicking a soft tissue sarcoma. Chronic osteomyelitis is an infrequent cause of a soft tissue mass and is usually diagnosed clinically by a combination of radiology and microbiology. Rarely, COM can mimic a primary bony neoplasm, but this is the first reported case where it mimicked a soft tissue sarcoma. The clinical, radiological, and histological appearances of this case will be discussed.

    2009-10-15

    The purpose of our study was to evaluate the CT findings of malarial spleens. We reviewed the patient records of 44 patients with malaria during a recent 3.5-year period and we selected 18 patients who underwent an abdominal CT scan. We retrospectively evaluated the CT findings of the malarial spleens and we compared then with those of a control group of 18 men. We analyzed the splenic size, whether or not there was mottled striped splenic enhancement during the arterial phase and the differences of splenic attenuation and the attenuation between the liver and spleen during the precontrast phase, the arterial phase and the portal phase between the two groups. In malarial patients, the spleen was enlarged in all cases (p < 0.001), and splenic attenuation and the degree of enhancement were significantly decreased during the precontrast phase, the arterial phase and the portal phase (p < 0.001). Loss of mottled striped enhancement during the arterial phase was seen in 11 cases (61.1%) (p < 0.001). The attenuation of the spleen was lower than that of the liver in 13 cases (72.2%) during the portal phase (p = 0.003) and in 1 case (5.6%) during the arterial phase (p = 1.000). Splenomegaly, decreased splenic enhancement, the lack of mottled striped enhancement during the arterial phase and lower attenuation than that of the liver during the portal phase are helpful CT findings to diagnose the malarial spleen.

  18. Comparison of murine hepatic accessory cells and splenic dendritic cells

    Accessory cells are required for proliferation and antibody synthesis of B lymphocytes and proliferation of T lymphocytes in primary immune responses in vitro. The obligatory cells derived from the spleen are referred to as dendritic cells. Accessory cells were isolated from normal adult livers which were functionally interchangeable with splenic DC. Both hepatic accessory cells (AC) and splenic DC adhere firmly to plastic culture dishes or wells within 2 hr; but hepatic AC, unlike splenic DC, do not detach during 22 hr additional incubation. Hepatic AC, unlike splenic DC, are not lysed or inactivated by monoclonal antibody 33D1 and C'. Hepatic AC and splenic DC are similarly sensitive to irradiation in vivo and insensitive to irradiation in vitro. Hepatic AC are separated with cells which are predominantly phagocytic and FcR+ and contain nonspecific esterase. Both hepatic AC and splenic DC are suppressed or eliminated by activation of NK cells in vivo, a phenomenon prevented by prior elimination of NK cells

  19. Results of Clinical Application of Scintillation Scanning of the Spleen on 500 Patients: Possibilities and Limits

    After injecting erythrocytes marked with radioactive substances and artificially damaged there is a rapid clearance of these cells from the blood-stream and sequestration in the spleen. The resultant high concentration of radioactivity in the spleen permits a good scintigraphic demonstration of the organ. For many reasons Na2Cr51O4 seems at present to be the most suitable substance for labelling erythrocytes, and alteration by heat the most practical means of damaging the cells. The systematic application of spleen scintigraphy on over 500 patients showed the following indications for this method: (1) Demonstration of enlargement of the spleen is not possible by clinical or roentgenological methods; (2) Verification of tumours in the upper left abdominal region; (3) Demonstration of accessory spleens after splenectomy; (4) Demonstration of ectopic spleens (situs inversus, ptosis); (5) Demonstration of parenchymal defects in the spleen (e.g. intrasplenic bleeding, infarcts of the spleen, necrosis of the spleen and intrasplenic cysts). By planimetric measurements of the scintigram area and by calculating the ''splenic surface area index'' (= scintigram area/body surface of the patient) a good quantitative estimation of the extent of spleen enlargement may be obtained. In healthy persons the surface area of the scintigram does not exceed 70- 80 cm2 and the splenic surface-area-index lies normally within 2.5 - 4.5 x 10-3. A comparison with the clinical findings showed that only one third of the spleens which were found by scintigraphy to be positively enlarged could be detected by percussion and palpation. In various diseases the clinical estimation.of spleen enlargement is false in an even higher percentage of the cases. Only when the spleen has completely lost the ability to sequestrate heat- altered erythrocytes is the scintigraphic depiction of the spleen impossible. Such cases, however, seem to be extremely rare; we have so far observed only one. Up to now the

    1995-11-01

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

  4. Urticaria mimickers in children.

    Mathur, Anubhav N; Mathes, Erin F

    2013-01-01

    Acute urticaria is a self-limited cutaneous condition marked by transient, erythematous, and pruritic wheals. It is a hypersensitivity response that is often secondary to infection, medications, or food allergies in children. In contrast, the urticarial "mimickers" described in this review article are often seen in the context of fever and extracutaneous manifestations in pediatric patients. The differential diagnosis ranges from benign and self-limited hypersensitivity responses to multisystem inflammatory diseases. Establishing the correct diagnosis of an urticarial rash in a pediatric patient is necessary to both prevent an unnecessary work up for self-limited conditions and to appropriately recognize and evaluate multisystem inflammatory disorders. Herein, we describe two cases to illustrate the clinical manifestations, laboratory findings, histopathology and differential diagnoses for several mimickers of acute urticaria including: urticaria multiforme, serum sickness like reaction, Henoch-Schönlein purpura, acute hemorrhagic edema of infancy, systemic onset juvenile idiopathic arthritis, cryopyrin associated periodic syndromes, and urticarial vasculitis.

  8. Spleen Scintigraphy in Hodgkin's Disease

    The authors give the results of scintigraphic studies carried out on patients suffering from Hodgkin's disease. They first give the technical details of the study, stressing the need for rigorous procedures in corpuscle labelling and alteration, and also the importance of collimation and of scanning at different angles of incidence; they then describe the different morphological characteristics encountered in scanning; in particular, they analyse dimensional and structural attributes of the image; among the latter they distinguish homogeneous and diffuse heterogeneous structures and also heterogeneous structures with gaps. They study these characteristics in relation to the age of the disease and relate them to the clinical and paraclinical context. The changes in the scanning image during treatment are also described and the authors stress the value of the scintigraphic method for checking on the development of splenic symptoms in the course of the disease. Lastly, they discuss the data obtained from analysis of blood and spleen radiation curves and give details on the findings of spleen scintigraphy. (author)

  10. The accessory fallopian tube: A rare anomaly

    Kusum R Gandhi

    2012-01-01

    Full Text Available This paper presents a rare anatomical variation in the form of accessory fallopian tube on right side. The duplication of fallopian tube was observed in a 34-year-old female during routine undergraduate dissection in our department. Fallopian tube is the part of uterus that carries the ovum from the ovary to the uterus. Accessory fallopian tube is the congenital anomaly attached to the ampullary part of main tube. This accessory tube is common site of pyosalpinx, hydrosalpinx, cystic swelling and torsion. The ovum released by the ovary may also be captured by the blind accessory tube leading to infertility or ectopic pregnancy. Hence, all patients of infertility or pelvic inflammatory disease should be screened to rule out the presence of accessory fallopian tube and if encountered should be removed.

    Full Text Available The Spleen is a large lymphoid organ situated in the left hypochondrial region having an important role in immunological and hematological functions of the human body. The aim of this study was to find the morphological variations of the spleen with respect to it’s a Shape, b Number of notches on its borders and c Presence of anomalous fissure on its surface. The Study was done on 60 formalin fixed cadaveric spleen from the Department of Anatomy, Narayana Medical College, Nellore, Andhra Pradesh. Out of 60 spleens we examined, the various shapes of the spleen were noted suc h as wedge shape (73.33%, triangular (13.33%, tetrahedral (6.67% and oval shape(6.67%.The number of spleen showing notches on its superior border was 38(63.33% and in inferior border it was 6(10%. Absence of splenic notch was observed in 10(16.67% s pleens and the remaining 6 spleens (10% shows notches on its both the borders. The anomalous splenic fissure was found in 4(6.67% spleens on its diaphragmatic surface. The knowledge of variations in the morphology of spleen are essential for physician, s urgeon, radiologist and forensic surgeon to differentiate it from the splenic pathology and splenic injury. In addition to this, it is also important for anatomist during routine classroom dissection and discussion.

  12. Errors made in the ultrasound diagnostics of the spleen.

    Walczyk, Joanna; Walas, Maria Krystyna

    2013-03-01

    Ultrasonography, like any imaging method, entails the risk of errors. From among all means of imaging, it is the most subjective and dependent on the examiner's knowledge and experience. This paper presents the causes of examiner-dependent errors as well as those which result from technical settings and preparation of the patient for the examination. Moreover, the authors discuss the most frequent errors in the diagnosis of splenic conditions, which result from insufficient knowledge concerning anatomical variants of this organ, wrong measurements and incorrect examination technique. The mistakes made in the differentiation of focal lesions of the spleen and its hilum are also discussed. Additionally, the differentiation of collateral circulation, lymph nodes and accessory spleens is mentioned. The authors also draw attention to erroneous interpretation of the left liver lobe as a fragment of the spleen as well as the prominent tail of the pancreas filled with gastric contents and intestinal loops as abnormal masses or fluid cisterns in the area of the splenic hilum. Furthermore, the pathologies of the hilum are discussed such as tumors of the splenic flexure of the colon, lesions arising from the left kidney or the left adrenal gland. The authors list characteristic imaging features of the most common focal lesions visualized in a standard ultrasound scan as well as enhancement patterns appearing in contrast-enhanced examinations. The article discusses the features and differentiation of, among others, infarction, splenic cysts including hydatid ones, abscesses and angiomas. The ultrasound appearance of lymphoma and secondary involvement of the spleen by other malignant neoplasms is also mentioned. Moreover, the authors provide useful tips connected with imaging techniques and interpretation of the findings. The ultrasound examination carried out in compliance with current standards allows for an optimal assessment of the organ and reduction of the error

  13. Carcinoma in accessory axillary breast.

    Khanna, Seema; Mishra, Shashi Prakash; Kumar, Satendra; Khanna, Ajay Kumar

    2015-01-01

    We present a rare case of carcinoma developing in an accessory breast. The patient presented with a progressive lump in her right axilla for 1 year. On examination, there was a well-developed nipple areola complex in the right axilla overlying a hard, fixed 5 × 3 cm lump. On investigation, core biopsy revealed poorly differentiated carcinoma of the breast. Mammography also revealed features of a malignant lesion with skin and muscle infiltration. Neoadjuvant chemotherapy was administered followed by modified radical mastectomy after three cycles. Immunohistochemistry study showed positive status of oestrogen and progesterone receptors, and negative HER-2 neu. Three more cycles of chemotherapy along with 50 Gy radiotherapy were given in an adjuvant setting followed by hormone therapy. PMID:26260957

  14. Scintillation Scanning of the Spleen with Red Cells Labelled with Cr51

    Satisfactory scintiscans of the spleen have been obtained using chromium-51-labelled red cells, modified by two methods. Initially red cells were sensitized in vitro by coating with incomplete anti-D antibody. In this method the concentration of sensitized red cells in the spleen is proportional to the volume of anti- D serum employed in the sensitization procedure. Satisfactory scintiscans were obtained using 0.50 ml of a 1:128 dilution of anti-D serum, having an original titre of 1: 512/ml of red cells. In spite of good results, the sensitization method, utilizable only in Rh positive patients, has been replaced by the method using red cells modified by heating, which is technically easier and may be used also in Rh negative patients. The image of the spleen is clearly delineated in all the cases, without interference from hepatic radioactivity. The spleen: liver ratio ranges between 5:1 and 10:1. To date scintillation scans of the spleen have been performed in about 60 patients. No immediate or delayed clinical reactions have been observed in the patients after the injection of sensitized or heated red cells. Since the radiation dose delivered to the patient is lower than the dose delivered in many radiological and clinical examinations with radioactive isotopes, the scanning procedure has been widely used in the differential diagnosis of the masses of the left abdomen. Among the cases studied, it is worth while mentioning two cases of splenomegaly associated with a tumour of the left kidney, one case of Banti's disease in a patient, in which a neoplasm of descending colon was suspected and a case of neuroblastomá in a patient two years old, in which the scintiscan of the spleen and that of the kidneys were of great help in making the right diagnosis. Further, the scintiscan has been of unique utility to rule out an accessory spleen and to demonstrate the spleen in congenital malformations, like situs inversus viscerum. In patients affected by chronic leukaemia

  15. Melanocortin receptors and their accessory proteins

    Cooray, Sadani N.; Clark, Adrian J.L.

    2010-01-01

    Abstract The melanocortin receptor family consists of 5 members which belong to the GPCR superfamily. Their specific ligands, the melanocortins are peptide hormones which are formed by the proteolytic cleavage of the proopiomelanocortin (POMC) protein. It is now recognised that certain GPCRs require accessory proteins for their function. Like these GPCRs the melanocortin receptor family is also known to be associated with accessory proteins that regulate their function. ...

    2013-12-01

    Accessory parotid gland tumors are relatively rare; hence, adequately detailed clinical analyses of these tumors are difficult to perform at a single institution. In this report, we describe the findings for 65 patients [29 men, 36 women; median age, 51 (9-81) years] with accessory parotid gland tumors, consisting of 4 cases documented by us and 61 cases previously reported by other Japanese authors. Approximately 50% of the patients were treated in an otolaryngology department, while the remaining patients were treated in plastic surgery, oral surgery, or dermatology departments. In 4 patients, the results of preoperative fine-needle aspiration cytology indicated that the tumor was benign; however, the postoperative histopathology results revealed malignant tumors. The frequencies of malignant and benign tumors were 44.6% (n = 29) and 55.4% (n = 36), respectively. Mucoepidermoid carcinoma and pleomorphic adenoma were the most frequent types of malignant and benign accessory parotid gland tumors, respectively. Among the various surgical methods that were used, such as direct cheek and intraoral incisions, a standard parotidectomy incision was the most preferred treatment approach for these tumors. Recently, an endoscopic approach has also been found to yield satisfactory results. An optimal approach should be selected after evaluating the advantages and disadvantages of these methods. No definite guidelines are available regarding the choice of elective neck dissection and postoperative radiation therapy for malignant accessory parotid gland tumors. Although tumor resection (plus elective neck dissection) and postoperative radiation therapy have been frequently performed for various kinds of malignant accessory parotid gland tumors to date, additional studies are needed regarding the criteria for selecting elective neck dissection and postoperative radiation therapy. Since the malignancy rate for accessory parotid gland tumors is higher than that for parotid gland

  17. Changing spleen size after blunt abdominal trauma

    The authors studied the incidence and significance of splenic enlargement on serial CT after abdominal trauma. Spleen size and density in 44 trauma patients were studied with serial, contrast-enhanced Ct. In 58% of the patients, ≥ 10% enlargement of the spleen was seen on follow-up scans. Ten patients had >50% enlargement. In several, the initial density of the spleen was less than that of the liver. Spleen density returned to normal on subsequent scans. Correlations between splenic changes and clinical parameters (such as blood replacement, hypotension, and various trauma indexes) were weak. The author's study indicated that serial splenic enlargement was a physiologic return to normal after major trauma, not a pathologic condition requiring splenectomy

  20. Computerized tomography examination of injured spleen

    In blunt abdominal injury, the spleen is most frequently injured. A rapid and accurate diagnosis of the injured spleen is therefore of great importance for early and correct therapeutic management. A group is discussed of 56 patients who were examined in the years 1981-1987 after blunt injury of the abdomen by computerized tomography. Computerized tomography is a very useful method which allows rapid and accurate noninvasive diagnosis of different degrees of spleen injury and its possible complications. In comparison with other methods, computerized tomography is the most effective method providing comprehensive information on other organs in the abdominal cavity. It also allows noninvasive examination of severely injured patients and of non-cooperating patients. (author). 6 figs., 1 tab., 15 refs

  12. Multicystic Hepatocarcinoma Mimicking Liver Abscess

    Evangelos Falidas

    2013-01-01

    Full Text Available The diagnosis of hepatocellular carcinoma (HCC became easier in relation to the improved radiological examinations; however, the neoplasm may occur under atypical presentations mimicking other benign or malignant processes. Multicystic HCC mimicking a liver abscess associated with septic-type fever and leukocytosis is rare, has a poor prognosis, and poses diagnostic and therapeutic dilemmas. We present the case of an 80-year-old patient, who presented with fever, leukocytosis, and large cystic masses involving right and left lobes of the liver initially considered abscesses and finally diagnosed as HCC after open drainage and liver biopsy. Although the patient died on the tenth postoperative day due to pulmonary oedema, the authors emphasize the high index of suspicion needed in the diagnosis of this unusual presentation of HCC.

  14. [Strategies for paediatric spleen and liver injuries].

    Zundel, S; Lieber, J; Tsiflikas, I; Henk, A-K; Schmittenbecher, P

    2014-12-01

    Traumatic injuries of the spleen and liver are typically caused by age-related falls or sports and traffic accidents. Today, the non-operative management for isolated injuries is established and evidence-based guidelines are available. The intact abdominal wall and the limited space within the peritoneum produce a compression which is the pathophysiological explanation for the limitation of the haemorrhage. Precondition for the non-operative therapy is the radiology-based classification of the injury (organ injury scale) and a haemodynamically stable patient. Haemodynamic stability is, if necessary maintained with blood transfusion, volume substitutes and the administration of catecholamines. In cases of hilar vascular injury and devascularisation or haemodynamic instability of the patient, despite utilisation of the measures mentioned above, urgent operative therapy needs to be performed. Organ sparing surgery is the therapy of choice for both liver and spleen. The spleen is required for the development of a competent immune system in the growing organism. Liver injuries can be further complicated by injury to the bile system, which might require operative reconstruction. If a patient suffers from multiple injuries and spleen or liver are involved, the decision on the management needs to be taken individually, no guidelines exist but the rate for operative therapy increases. Independent of the dimensions of injury, an experienced paediatric surgeon with his multidisciplinary team, considering the anatomic and age specific characteristics of a child, achieves the best therapeutic results.

    The level of autophagy is considered as an indicator for monitoring the toxic impact of pesticide exposure. Avermectin (AVM), a widely used insecticide, has immunotoxic effects on the pigeon spleen. The aim of this study was to investigate the status of autophagy and the expression levels of microtubule-associated protein1 light chain 3 (LC3), beclin-1, dynein, autophagy associated gene (Atg) 4B, Atg5, target of rapamycin complex 1 (TORC1) and target of rapamycin complex 2 (TORC2) in AVM-treated pigeon spleens. Eighty two-month-old pigeons were randomly divided into four groups: a control group, a low-dose group, a medium-dose group and a high-dose group, which were fed a basal diet spiked with 0, 20, 40 and 60 mg AVM/kg diet, respectively. Microscopic cellular morphology revealed a significant increase in autophagic structures in the AVM-treated groups. The expression of LC3, beclin-1, dynein, Atg4B and Atg5 increased, while mRNA levels of TORC1 and TORC2 were decreased in the AVM-treated groups relative to the control groups at 30, 60 and 90 days in the pigeon spleen. These results indicated that AVM exposure could up-regulate the level of autophagy in a dose-time-dependent manner in the pigeon spleen. PMID:26541719

  16. Impacts of Humanized Mouse Models on the Investigation of HIV-1 Infection: Illuminating the Roles of Viral Accessory Proteins in Vivo

    Eri Yamada

    2015-03-01

    Full Text Available Human immunodeficiency virus type 1 (HIV-1 encodes four accessory genes: vif, vpu, vpr, and nef. Recent investigations using in vitro cell culture systems have shed light on the roles of these HIV-1 accessory proteins, Vif, Vpr, Vpu, and Nef, in counteracting, modulating, and evading various cellular factors that are responsible for anti-HIV-1 intrinsic immunity. However, since humans are the exclusive target for HIV-1 infection, conventional animal models are incapable of mimicking the dynamics of HIV-1 infection in vivo. Moreover, the effects of HIV-1 accessory proteins on viral infection in vivo remain unclear. To elucidate the roles of HIV-1 accessory proteins in the dynamics of viral infection in vivo, humanized mouse models, in which the mice are xenotransplanted with human hematopoietic stem cells, has been utilized. This review describes the current knowledge of the roles of HIV-1 accessory proteins in viral infection, replication, and pathogenicity in vivo, which are revealed by the studies using humanized mouse models.

  17. Alternative delivery of male accessory gland products

    Zizzari, Z Valentina; Smolders, Irene; Koene, Joris M

    2014-01-01

    To increase fertilization success, males transfer accessory gland products (Acps). Several species have evolved unconventional Acps transfer modes, meaning that Acps are transferred separately from the sperm. By surveying the sperm-free Acps transfer cases, we show that these animals have evolved a common strategy to deliver Acps: they all inject Acps directly through the partner’s body wall into the hemolymph. Our review of this mode of Acps transfer reveals another striking similarity: they...

  20. Studies on Prion Replication in Spleen

    Raeber, Alex J.; Fabio Montrasio; Ivan Hegyi; Rico Frigg; Klein, Michael A.; Adriano Aguzzi; Charles Weissmann

    2001-01-01

    Some of the early events following scrapie infection take place in the lymphoreticular system (LRS) and result in significant replication of prions in lymphoid organs. The identity of the cells in the LRS that produce prions and their role in neuroinvasion are still unknown. We find that in the spleen of scrapie-infected mice, prions are associated with T and B cells and to a somewhat lesser degree with the stroma, which contains the follicular dendritic cells (FDC's); curiously, no infectivi...

    Full Text Available Introduction. Since the first description of primary splenic malignant fibrous histiocytoma given by Govoni et al. in 1982, there have been only 18 reported cases by the end of 2013. We herein reported a case of rare primary malignant fibrous histiocytoma of the spleen with liver metastases and unspecific general symptoms. Case Report. A 62-year-old cachectic female complained of sharp strong abdominal pain (on the pain scale 8/10 and distaste for food on admission at Primary Care Service on March 29, 2014. On physical examination, palpable painful 2 cm long tumefact in the left hypochondriac segment was found. Laboratory findings showed leukocytosis 17.9 x 109/l, erythrocyte sedimentation rate of 55 mm/h, C reactive protein 25.8. Magnetic resonance of abdomen proved secondary deposits in the right liver segment and lower pole of spleen. Positron emission tomography-computed tomography recorded a cold necrosis field in the right liver part and lobulated cystic formation of spleen. After radiological examination, splenectomy and resection of the pancreas cauda were performed. Primary malignant splenic fibrous histiocytoma with liver metastases was proved histopathologically. The patient was given three chemotherapeutic series until October 2, 2014 and she is now in good general condition. Conclusion. The possibility of primary malignant splenic fibrous histiocytoma should be considered in every case with proved intra-abdominal masses of unknown origin. Clinical and laboratory findings are unspecific. Surgical resection with histopathological evaluation is the most effective diagnostic and therapeutic procedure.

  3. Isolated spinal accessory neuropathy and intracisternal schwannomas of the spinal accessory nerve

    Abdullah M. Al-Ajmi

    2015-03-01

    Full Text Available We report a 40-year-old female patient presenting with isolated left spinal accessory neuropathy that developed insidiously over 6 years. She complained of ill-defined deep neck and shoulder pain. On examination, prominent sternocleidomastoid and trapezoid muscle weakness and atrophy, shoulder instability, and lateral scapular winging were observed. MRI identified a small mass of the cisternal portion of the spinal accessory nerve. Its appearance was typical of schwannoma. Surgical treatment was not offered because of the small tumor size, lack of mass effect and the questionable functional recovery in the presence of muscular atrophy.

  4. Imaging of the symptomatic type Il accessory navicular bone

    Accessory ossicles of the foot are commonly mistaken for fractures. The accessory navicular is one of the most common accessory ossicles of the foot. There is a higher incidence in women and the finding might be bilateral in 50-90%. This entity is usually asymptomatic, although populations with medial foot pain have a higher prevalence. Three types of accessory navicular bone have been described. The type Il accessory navicular is the most commonly symptomatic variant with localized chronic or acute on chronic medial foot pain and tenderness with associated inflammation of overlying soft tissues. Plain radiographic identification of the accessory navicular is insufficient to attribute symptomatology. Ultrasound allows for comparison with the asymptomatic side and localization of pain. Bone scintigraphy has a high sensitivity but positive findings lack specificity. Magnetic resonance imaging is of high diagnostic value for demonstrating both bone marrow and soft tissue oedema.

  7. Black hole mimickers: Regular versus singular behavior

    Black hole mimickers are possible alternatives to black holes; they would look observationally almost like black holes but would have no horizon. The properties in the near-horizon region where gravity is strong can be quite different for both types of objects, but at infinity it could be difficult to discern black holes from their mimickers. To disentangle this possible confusion, we examine the near-horizon properties, and their connection with far away asymptotic properties, of some candidates to black mimickers. We study spherically symmetric uncharged or charged but nonextremal objects, as well as spherically symmetric charged extremal objects. Within the uncharged or charged but nonextremal black hole mimickers, we study nonextremal ε-wormholes on the threshold of the formation of an event horizon, of which a subclass are called black foils, and gravastars. Within the charged extremal black hole mimickers we study extremal ε-wormholes on the threshold of the formation of an event horizon, quasi-black holes, and wormholes on the basis of quasi-black holes from Bonnor stars. We elucidate whether or not the objects belonging to these two classes remain regular in the near-horizon limit. The requirement of full regularity, i.e., finite curvature and absence of naked behavior, up to an arbitrary neighborhood of the gravitational radius of the object enables one to rule out potential mimickers in most of the cases. A list ranking the best black hole mimickers up to the worst, both nonextremal and extremal, is as follows: wormholes on the basis of extremal black holes or on the basis of quasi-black holes, quasi-black holes, wormholes on the basis of nonextremal black holes (black foils), and gravastars. Since in observational astrophysics it is difficult to find extremal configurations (the best mimickers in the ranking), whereas nonextremal configurations are really bad mimickers, the task of distinguishing black holes from their mimickers seems to be less

  8. Accessory slips of the extensor digiti minimi.

    Li, Jing; Mao, Qing Hua

    2014-01-01

    During the educational dissection of a 69-year-old Chinese male cadaver, an extensor digiti minimi (EDM) with five slips on the right hand was discovered. Except for the two slips of the little finger, the two radial slips were inserted into the dorsal aponeurosis of the middle finger and the ring finger, respectively. The middle slip was connected to the junctura tendinum in the fourth intermetacarpal spaces. Variations in this region are of paramount importance for the reconstructive surgeons, who may utilize the accessory slips to restore functional capacity of the fingers. PMID:24970007

  9. Relationship between number of spleen colonies and 125IdUrd incorporation into spleen and femur

    Graded numbers of bone marrow (BM) cells were injected into fatally irradiated mice. Eight days later the mice were given 3.0 μCi (1 Ci = 3.7 x 1010Bq) of 125IdUrd to label proliferating cells in the spleen and BM. On day 9 the mice were killed and the spleens and femurs were removed for splenic colony assay and measurement of radioactivity in the spleen and femurs. The number of splenic colonies shows a linear relationship with dose of marrow cells injected from 104 to 105 cells. The slope of the curve of spleen colonies versus number of cells injected is 5 and below 104 there is a striking departure from the simple linearity. Below 2 x 103 cells injected, the logarithm of the observed colony yield is linear with logarithm of the number of cells injected. Poisson calculation of the average number of pluripotent stem cells that should be present with numbers of marrow cells injected below 2 x 103 followed closely the actual observations. The data show that there is no detectible proliferation in the BM until the dose of marrow cells exceeds 3.5 x 104 cells. Induction of cells into cycle increases the seeding into the BM, and thymidine cytocide drastically reduces seeding in the BM, leading us to conclude that the BM is repopulated almost exclusively by stem cells in DNA synthesis

  15. MCMV exploits the spleen as a transfer hub for systemic dissemination upon oronasal inoculation.

    Zhang, Shunchuan; Xiang, Jun; Theuns, Sebastiaan; Desmarets, Lowiese M B; Trus, Ivan; Nauwynck, Hans J

    2016-06-01

    Murine cytomegalovirus (MCMV) infection in mice is a commonly used animal model for studying human cytomegalovirus (HCMV) infections. In our previous studies, a mouse model based on an oronasal MCMV infection was set up for mimicking a natural infection, and the spleen was hypothesized to regulate viremia and virus dissemination to distal organs such as submandibular glands. Here, the role of the spleen during an MCMV infection was investigated by the comparison of intact and splenectomized Balb/c mice. Both highly passaged MCMV Smith and low passaged MCMV HaNa1 were used. Various samples were collected at 7, 14, and 21 days post inoculation (dpi) for analyses by virus isolation/titration, co-cultivation and qPCR. The results showed that for both virus strains, 1) cell-associated virus in PBMC (determined by co-cultivation) was detected in intact mice but not in splenectomized mice; 2) the mean viral DNA load in PBMC of splenectomized mice was 4.4-(HaNa1)/2.7-(Smith) fold lower at the peak viremia (7dpi) in contrast to that of intact mice; and 3) infectious virus in the submandibular glands was detected later in splenectomized mice (14dpi) than in intact mice (7dpi). Moreover, the average virus titers in submandibular glands of splenectomized mice were 10-(HaNa1)/7.9-(Smith) fold lower at 14dpi and 1.7-(HaNa1)/2.1-(Smith) fold lower at 21dpi compared with that of intact mice. Upon inoculation with MCMV Smith, infectious virus was found in the kidneys and liver of intact mice, but not in splenectomized mice. Taken together, all these data clearly demonstrate that virus dissemination to distant organs is reduced in splenectomized mice, further confirming the importance of the spleen as a viremia booming site for a natural MCMV infection.

    An electrical cable accessory includes a generally tubular member of elastomeric material which is to be installed by placement over a cylindrical surface to grip the cylindrical surface, when in appropriate assembled relation therewith, with a predetermined gripping force established by dilation of the tubular member, the installation being facilitated by introducing fluid under pressure, through means provided in the tubular member, between the tubular member and the cylindrical surface, and simultaneously impeding the escape of the fluid under pressure from between the tubular member and the cylindrical surface by means adjacent one of the ends of the tubular member to cause dilation of the tubular member and establish a fluid layer between the tubular member and the cylindrical surface, thereby reducing the gripping force during installation.

  5. Bartonella henselae Infection: An Uncommon Mimicker of Autoimmune Disease.

    Maritsi, Despoina N; Zarganis, Diagoras; Metaxa, Zoi; Papaioannou, Georgia; Vartzelis, George

    2013-01-01

    We present a case of a seven-year-old immunocompetent female patient who developed systemic symptoms mimicking an autoimmune rather than an infectious disease. The patient presented with rash, biquotidian fever, night sweats, and arthralgias. There was no antecedent history of cat contact. Investigations showed increased inflammatory markers, leukocytosis, thrombocytosis, hypercalcemia, and raised angiotensin-converting enzyme. Interferon-gamma releasing assay for tuberculosis infection was negative. Abdominal imaging demonstrated multifocal lesions of the liver and spleen (later proved to be granulomata), chest X-ray showed enlarged hilar lymph nodes, and ophthalmology review revealed uveitis. Clinical, laboratory, and imaging features pointed towards sarcoidosis. Subsequently, raised titers (IgM 1 : 32, IgG 1 : 256) against Bartonella confirmed the diagnosis of B. henselae infection. She was treated with gentamycin followed by ciprofloxacin; repeat investigations showed complete resolution of findings. The presence of hepatic and splenic lesions in children with bartonellosis is well documented. Our case, however, exhibited certain unusual findings such as the coexistence of acute ocular and systemic involvement in an immunocompetent host. Serological testing is an inexpensive and effective way to diagnose bartonellosis in immunocompetent patients; we suggest that bartonella serology is included in the baseline tests performed on children with prolonged fever even in the absence of contact with cats in countries where bartonellosis is prevalent.

  7. Spleen volume on CT and the effect of abdominal trauma.

    Cruz-Romero, Cinthia; Agarwal, Sheela; Abujudeh, Hani H; Thrall, James; Hahn, Peter F

    2016-08-01

    The aim of this study is to determine the magnitude of change in spleen volume on CT in subjects sustaining blunt abdominal trauma without hemorrhage relative to patients without disease and how the spleen volumes are distributed. Sixty-seven subjects with blunt abdominal trauma and 101 control subjects were included in this retrospective single-center, IRB-approved, and HIPAA-compliant study. Patients with an injured spleen were excluded. Using a semiautomatic segmentation program, two readers computed spleen volumes from CT. Spleen volume distribution in male and female trauma and control cohorts were compared nonparametrically. Spleen volume plotted against height, weight, and age were analyzed by linear regression. The number of females and males are, respectively, 35 and 32 in trauma subjects and 69 and 32 among controls. Female trauma patients (49.6 years) were older than males (39.8 years) (p = 0.02). Distributions of spleen volume were not normal, skewed above their means, requiring a nonparametric comparison. Spleen volumes in trauma patients were smaller than those in controls with medians of 230 vs 294 mL in males(p volume correlated positively with weight in females and with height in male controls, and negatively with age in male controls (p volume in controls was 245 mL, the largest ever reported. Spleen volume decreases in response to blunt abdominal trauma. Spleen volumes are not normally distributed. Our population has the largest spleen volume reported in the literature, perhaps a consequence of the obesity epidemic. PMID:27166964

    2011-01-01

    Background Distal pancreatectomy traditionally included splenectomy; the spleen, however, is an important organ in the immunologic defense of the host and is worthy of preservation. The aim of this research was to study the feasibility,safety and clinical effects of spleen and splenic vessel-preserving distal pancreatectomy.Methods A retrospective review was performed for 26 patients undergoing distal pancreatectomy for benign or low grade malignant disease with splenectomy (n=13) or splenic preservation (n=13) at the First Hospital of Sun Yat-sen University and Guangdong General Hospital in Southern China from May 2002 to April 2009.Results All 26 pancreatectomies with splenectomy or splenic preservation were performed successfully. There was no statistically significant difference between two groups in mean operative time ((172±47) minutes vs. (157±52) minutes, P >0.05), intraoperative estimated blood loss ((183±68) ml vs. (160±51) ml, P >0.05), incidence of noninfectious and infection complication and mean length of postoperative hospital stay ((10.1±2.2) days vs. (12.1 ±4.6) days, P >0.05). The platelet counts examined one week after operation were significantly higher in the distal pancreatectomy with splenectomy group than the other group ((37.3±12.8)×109/L vs. (54.7±13.2)×109/L, P <0.05).Conclusions Spleen-preserving distal pancreatectomy appears to be a feasible and safe procedure. In selected cases of benign or low-grade malignant disease, spleen-preserving distal pancreatectomy is recommended.

    Full Text Available Abstract Background Cases of giant hydronephroses are rare and usually contain no more than 1–2 litres of fluid in the collecting system. We report a remarkable case of giant hydronephrosis mimicking a progressive malignant abdominal tumour. Case presentation A 78-year-old cachectic woman presented with an enormous abdominal tumour, which, according to the patient, had slowly increased in diameter. Medical history was unremarkable except for a hysterectomy >30 years before. A CT scan revealed a giant cystic tumour filling almost the entire abdominal cavity. It was analysed by two independent radiologists who suspected a tumour originating from the right kidney and additionally a cystic ovarian neoplasm. Subsequently, a diagnostic and therapeutic laparotomy was performed: the tumour presented as a cystic, 35 × 30 × 25 cm expansive structure adhesive to adjacent organs without definite signs of invasive growth. The right renal hilar vessels could finally be identified at its basis. After extirpation another tumourous structure emerged in the pelvis originating from the genital organs and was also resected. The histopathological examination revealed a >15 kg hydronephrotic right kidney, lacking hardly any residual renal cortex parenchyma. The second specimen was identified as an ovary with regressive changes and a large partially calcified cyst. There was no evidence of malignant growth. Conclusion Although both clinical symptoms and the enormous size of the tumour indicated malignant growth, it turned out to be a giant hydronephrosis. Presumably, a chronic obstruction of the distal ureter had caused this extraordinary hydronephrosis. As demonstrated in our case, an accurate diagnosis of giant hydronephrosis remains challenging due to the atrophy of the renal parenchyma associated with chronic obstruction. Therefore, any abdominal cystic mass even in the absence of other evident pathologies should include the differential diagnosis of a

  10. The association of hallux limitus with the accessory navicular.

    Evans, R D Lee; Averett, Ryan; Sanders, Stephanie

    2002-06-01

    Hallux limitus is one of the most prevalent, debilitating disorders of the first metatarsophalangeal joint, and it has many proposed etiologies. This article reviews these etiologies, focusing primarily on the pes planus foot. The pes planus foot type is often associated with symptomatic hallux limitus and the accessory navicular. This article discusses this correlation, although a causal relationship has not been proven. The prevalence and classification of the accessory navicular are also discussed. Clinical cases involving symptomatic hallux limitus occurring concomitantly with an accessory navicular are reviewed, including radiographic findings, symptoms, and surgical treatment. PMID:12070237

    Inflammatory pseudotumors, also known as inflammatory miyofibroblastic tumors, are rare benign tumors of the spleen. The diagnosis of these tumors may be difficult, because they simulate some hematopoetic malignancies, leiomyosarcomas, inflammatory malignant fibrous histiocytoma and inflammatory fibrosclerosing lesions. They frequently occur at lung. But they are reported at gastrointestinal system, orbit, liver, bladder, lymph nodes, heart, brain, mesentery, omentum and spleen. Histologicall...

    Invaginations of the liver by the diaphragm form accessory fissures that may mimic the major hepatic fissures on sectional images. Accessory fissures are most common in the superior right hepatic lobe. Their average incidence on computed tomographic (CT) scans is 25%. Their frequency increases with age, approaching 70% in the seventh and eighth decades. Their depth may equal or exceed 2 cm in one-third of cases. Multiple accessory fissures may mimic pathologic liver nodules on CT and may be associated with diaphragmatic scalloping or eventration on the chest film. When only parts of these fissures are seen sonographically, they may be mistaken for echogenic liver lesions. The differentiation of accessory fissures from the major hepatic fissures, from pathologic lesions, and from sonographic pseudofissure artifacts is discussed.

    2015-01-01

    Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve) followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferior...

  3. Mammographic appearance of accessory breast tissue in the axilla

    Objective: To observe the mammographic appearance of accessory breast tissue in the axilla. Methods: In the past 3 years, 7562 women were underwent bilateral screen-film mammography. All of the mediolateral oblique (MLO) films were reviewed retrospectively to look for whether there was accessory breast tissue and what the mammographic features were like. Radiographically the accessory tissue resembled the main normal breast glandular tissue but was separated from it. Results: Of the 7652 case, accessory breast tissue in the axilla was detected in 161 cases. The prevalence was 2%. The age ranged from 17 to 70 years (mean, 39 years). 38% of them were found in the bilateral axilla, 42% only in the right, and 20% only in the left. The dimensions on the right ranged from 0.7 to 8.0 cm (mean, 3.5 cm), and that on the left ranged from 1.0 to 7.0 cm (mean, 3.3 cm). There were four types among the accessory breast tissue: patchy type was the most (35%), then the branched type (26%), mixed type (20%), and mass-like type (19%). 3 cases were proved by pathology. Conclusion: It is important that the radiologist be familiar with the mammographic appearance of accessory breast tissue in the axilla in order that they could be distinguished from other pathological changes

  14. The Spleen Revisited: An Overview on Magnetic Resonance Imaging

    João Palas

    2013-01-01

    Full Text Available Despite being well visualized by different cross-sectional imaging techniques, the spleen is many times overlooked during the abdominal examination. The major reason is the low frequency of splenic abnormalities, the majority consisting of incidental findings. There has been a steady increase in the number of performed abdominal magnetic resonance imaging (MRI studies; therefore, it is important to be familiar to the major MRI characteristics of disease processes involving the spleen, in order to interpret the findings correctly, reaching whenever possible the appropriate diagnosis. The spleen may be involved in several pathologic conditions like congenital diseases, trauma, inflammation, vascular disorders and hematologic disorders, benign and malignant tumors, and other disease processes that focally or diffusely affect the spleen. This paper presents a description and representative MRI images for many of these disorders.

    2014-01-01

    Inflammatory pseudotumor(IPT) of the spleen is an uncommon entity with an uncertain aetiology. Inflammatory pseudotumors present diagnostic difficulties because the clinical and radiological findings tend to suggest a malignancy. The symptoms include weight loss, fever, and abdominal pain. Most cases of splenic IPT present solitary relatively large well circumscribed masses on imaging. The diagnosis in the majority of the cases is made after histopathologic study of splenectomy specimens. The IPTs that occur in the spleen and liver are typically associated with Epstein-Barr virus. Thirtyseven percent of all new cases of active tuberculosis infection are extrapulmonary tuberculosis and tuberculous lymphadenitis the most commonly occurring form of extrapulmonary tuberculosis. We report the case of an inflammatory pseudotumor of the spleen associated with splenic tuberculous lymphadenitis in a 50-year-old female patient who was preoperatively diagnosed with a malignant spleen tumour based on her history of breast of carcinoma.

  19. CT numbers of liver and spleen in normal children

    To determine the mean liver CT numbers, and differences between liver and spleen, and liver and back muscle CT numbers in normal children, and to correlate the findings with sex and age. One hundred and five normal children aged 2-14 years underwent pre-contrast CT scanning. Mean CT numbers of the liver, spleen, and back muscles were calculated, as well as the differences in CT numbers between the liver and spleen (liver-spleen CT numbers), and between the liver-back muscle CT numbers were 70.22±6.51 HU, 53.28±3.57 HU, 17.13±6.57 HU, and 11.88±5.94 HU, respectively. Mean liver CT numbers and the difference between liver and back muscle CT numbers were not different by age. By sex, all the CT numbers did not vary according to age. The sex of a subject did not affect the CT number. The children's mean liver CT number was 70.22±6.51 HU and the difference between liver and spleen CT numbers was 17.13±6.57 HU. Younger children had higher liver CT and liver-spleen CT numbers than older children. No CT numbers varied according to sex

    2000-09-01

    To evaluate the angiographic anatomy of the accessory left gastric artery (accLGA). We evaluated the angiographic findings of the accLGA in 50 patients (Angiostar; Siemens, Erlangen, Germany). Performing celiac and selective angiography in 50 and 34 patients, respectively. By means of celiac angiography, (1) site of origin, (2) anatomical course, (3) diameter, (4) degree of tortuosity, and (5) distal tapering were evaluated, while selective angiography was used to determine (1) arterial branching, (2) area of blood supply, and (3) patterns of gastric wall stain. Celiac angiography showed that the accLGA arose from the left hepatic artery (LHA) in 45 cases (90%) and from the proper hepatic artery in five (10%). If the accLGA arose from the LHA, its origin entirely depended on the branching pattern of the latter. It always arose from the lateral branch of the LHA furthest to the left and uppermost, and proximal to its umbilical point. The most common anatomical course of the accLGA, seen in 27 cases (54%), was between the S2 and S3 segmental branch. The diameter and degree of tortuosity of the accLGA were similar to those of adjacent intrahepatic branches in 21 (42%) and 33 cases (66%), respectively. The degree of tapering was less than that of adjacent intrahepatic vessel in 28 (56%). Selective angiography demonstrated esophageal branching of the acc LGA in 27 cases (79%), inferior phrenic arterial branching in three (9%), a mediastinal branch in one (3%), and hypervascularity of the lung in one (3%). In 15 cases (44%), bifurcation of the accLGA was recognized. The vascular territory of the accLGA was the gastric fundus together with the distal esophagus in 21 cases (62%), mainly the gastric fundus in six (18%), and mainly the distal esophagus in four (12%). The pattern of gastric mucosal stain was curvilinear wall in 31 cases (91%) and nodular in three (9%). A knowledge of the angiographic anatomy of the accLGA facilitates accurate recognition of this artery on

  1. Modulation of macrophage Ia expression by lipopolysaccharide: Stem cell requirements, accessory lymphocyte involvement, and IA-inducing factor production

    The mechanism of induction of murine macrophage Ia expression by lipopolysaccharide (LPS) was studied. Intraperitoneal injection of 1 microgram of LPS resulted in a 3- to 10-fold increase in the number of IA-positive peritoneal macrophages (flow cytometry and immunofluorescence) and a 6-to 16-fold increase by radioimmunoassay. The isolated lipid A moiety of LPS was a potent inducer of macrophage Ia expression. Ia induction required a functional myelopoietic system as indicated by the finding that the response to LPS was eliminated in irradiated (900 rads) mice and reinstated by reconstitution with bone marrow cells. Comparison of LPS-induced Ia expression in normal and LPS-primed mice revealed a faster secondary response to LPS. The memory response could be adoptively transferred to normal mice with nonadherent spleen cells prepared 60 days after LPS injection. Spleen cells prepared 5 days after LPS injection caused Ia induction in LPS-nonresponder mice; such induction was not observed in irradiated (900 rads) recipients. The cell responsible for this phenomenon was identified as a Thy-1+, immunoglobulin-negative nonadherent cell. The biosynthesis and expression of Ia were not increased by direct exposure of macrophages to LPS in vitro. Small amounts of LPS inhibited Ia induction by gamma interferon. LPS showed positive regulatory effects on Ia expression by delaying the loss of Ia expression on cultured macrophages and by stimulating the production of Ia-inducing factors. Supernatants from cultured spleen cells stimulated with LPS in vitro contained antiviral and Ia-inducing activity that was acid labile, indicating that the active factor is gamma interferon. We conclude that induction of Ia expression by LPS in vivo is a bone-marrow-dependent, radiation-sensitive process which involves the stimulation of a gamma interferon-producing accessory lymphocyte and a delay in Ia turnover

  2. Directly radiolabeled phage with spleen-targeting specificity

    Phage display technique is a powerful approach for discovering new tumor-and organ-targeting ligands, and radiolabeled phage has a potential to analyze the phage-binding sensitivity and specific imaging. In this study, phage II (the spleen-targeting phage) in mice was isolated after three rounds biopanning, and labeled by 99mTc using mercaptoacetyltriglycine (MAG3) as chelator to evaluate their binding properties in vivo. The amount of phage II eluted from spleen was enriched by plague assay each round. 99mTc-MAG3-phage II showed the less retention in blood at any time point than half that of 99mTc-MAG3-phage I (the radiolabeled original Ph. D-12 phage as control). The accumulation in spleen between 99mTc-MAG3-phage I and II was of different tendency. The highest uptake of 99mTc-MAG3-phage II in spleen was 24.80 % ID/g at 30 min; and of 99mTc-MAG3-phage I, 30.93% ID/g at 5 min. After circulating 99mTc-MAG3-phage II for 120 min, its accumulation in spleen decreased though higher than that of 99mTc-MAG3-phage I. In other organs, the 99mTc-MAG3-phage I showed low retention and high spleen-to-organ or tissue ratios. In conclusion, the radiolabeled phage II is convenient for studying the binding and specificity of spleen-targeting peptides found via phage display in vivo. (authors)

    2011-01-01

    Acute coronary syndromes among young adults are relatively low when compared with older population in the intensive care unit. Electrocardiographic abnormalities mimicking acute coronary syndromes may be caused by non-coronary syndromes and the differential diagnosis requires a detailed evaluation. We are reporting a case of myopericarditis presenting with acute ST elevation and elevated cardiac enzymes simulating acute coronary syndrome. In this case report, the literature is reviewed to dis...

  7. A Pilocytic Astrocytoma Mimicking a Clinoidal Meningioma

    Hong, Christopher S.; Lehman, Norman L.; Eric Sauvageau

    2014-01-01

    Pilocytic astrocytomas and meningiomas are benign, primary brain tumors that may involve the optic tract. Classically, the presence of a dural “tail” sign may differentiate a meningioma from other intracranial lesions. In this report, we describe a mass with the typical appearance of a clinoidal meningioma on magnetic resonance imaging (MRI) but postoperatively diagnosed as a pilocytic astrocytoma. This case illustrates the rare occurrence of a pilocytic astrocytoma mimicking a meningioma on ...

    2013-01-01

    Water quality in urban areas can be enhanced by biomimicry. In this study, we mimicked the forest by growing vegetables in 6’ x 3’ beds called oasissofas copying a ‘forest ecosystem’ of: continues mulch; minimum soil disturbance – no tillage; and spatial and rotational species diversification. A highly fertilized, compacted and herbicide applied monoculture lawn at the North Carolina Agricultural and Technical State University campus was converted into an experimental site to test if an oasis...

    Yanamandra, Uday; Gupta, Amul; Patyal, Sagarika; Varma, Prem Prakash

    2014-01-01

    High-altitude cerebral oedema (HACO) is the most fatal high-altitude illness seen by rural physicians practising in high-altitude areas. HACO presents clinically with cerebellar ataxia, features of raised intracranial pressure (ICP) and coma. Early identification is important as delay in diagnosis can be fatal. We present two cases of HACO presenting with focal deficits mimicking stroke. The first patient presented with left-sided hemiplegia associated with the rapid deterioration in the sens...

    Full Text Available Introduction. In closed trauma of the most frequent causes of injuries are haemoperitoneus of parenchymatous organs such as liver and spleen. Patients and methods. Clinical Case No.1. R.F. (spleen injury: 2nd degree sec. Moore, 1st degree sec. Buntain WL, Tc-based score of 2 is subject to clinical monitoring with ultrasound control, tc, and several blood exams with a satisfactory clinical outcome. Clinical Case No.2. A.C. presents a clinical picture attributable to 3rd grade sec. Moore and the 2nd grade sec. Buntain WL with a Tc-based score of 4, therefore, performed emergency splenectomy was not delayed, thus saving the patient at the death. Results. The rupture of the spleen is the most frequent complication of closed abdominal trauma (contusion or direct backlash. It appears as isolated lesion in 30-70% of cases. Conclusions. In our experience individual spleen injuries, undercapslular that does not involve the hilum and without spillage of liquid peritoneal deserve a conservative, on the other hand, the spleen injury in excess of 4 cm, manyfragments, with spreading of free peritoneal fluid in need of treatment Surgical sudden.

  12. Effects of gold sodium thiomalate on murine spleen cells

    The effects of gold sodium thiomalate (GST) on Balb/c murine spleen cells were investigated using in vitro mitogen blastogenesis techniques. Initial culture of spleen cells in the presence of concanavalin A (Con A) and GST exhibited inhibition of 3H-thymidine uptake due to gold. Spleen cells depleted of monocytes/macrophages by carbonyl iron-ingestion and cultured with Con A and GST demonstrated biphasic effects by gold on thymidine uptake depending upon the Con A and GST concentrations. A final concentration of 2.5 μg/ml con A showed a decreased inhibition of blastogenesis by gold, with macrophage depleted cells as compared to intact spleen cells. While a final concentration of 0.5 μg/ml Con A showed an increased inhibition of blastogenesis by gold with macrophage depleted cells as compared to intact spleen cells. GST was found to be most effective at inhibiting proliferation when present at the initiation of culture. GST was also found to inhibit responsiveness of cells previously incubated with mitogen and its presence in the culture media was required for at least 24-36 hours to produce significant inhibition. These results indicate that the greatest effects of GST on blastogenesis occur during the initial steps of lymphocyte activation and that macrophages may not be the only cell of gold action

  13. Antidromic Atrioventricular Reciprocating Tachycardia Using a Concealed Retrograde Conducting Left Lateral Accessory Pathway.

    Gonzalez, Jaime E; Zipse, Matthew M; Nguyen, Duy T; Sauer, William H

    2016-03-01

    Atrioventricular reciprocating tachycardia is a common cause of undifferentiated supraventricular tachycardia. In patients with manifest or concealed accessory pathways, it is imperative to assess for the presence of other accessory pathways. Multiple accessory pathways are present in 4% to 10% of patients and are more common in patients with structural heart disease. In rare cases, multiple accessory pathways can act as the anterograde and retrograde limbs of the tachycardia. PMID:26920167

    Lopez Milena, G.; Ruiz Santiago, F.; Canadillas Barea, L. [Dept. of Radiology, University Hospital, Granada (Spain); Chamorro Santos, C. [Dept. of Pathology, University Hospital, Granada (Spain)

    2001-08-01

    We present a case of forearm soft tissue mass caused by an accessory muscle, distal and deep to flexor carpi ulnaris muscle. Imaging studies, mainly magnetic resonance and ultrasound, allow a specific diagnosis, and obviate unnecessary surgery. In this case, the symptoms associated with ulnar compression led to surgery and confirmed the preoperative diagnosis. (orig.)

  18. [Radiofrequency ablation of accessory pathways in pre-excitation syndrome].

    Pfeiffer, D; Tebbenjohanns, J; Jung, W; Manz, M; Lüderitz, B

    1993-04-16

    Various parameters relating to the radio-frequency ablation of accessory pathways were studied in 53 patients (27 males, 26 females: mean age 38.5 [14-64] years) with a history of paroxysmal tachycardia (over 1 month to 50 years), shown to be caused by an accessory pathway (Wolff-Parkinson-White syndrome). In all patients the following values were obtained: (1) number of procedures necessary to achieve permanent blockage of the accessory pathway (1-4); (2) duration of each procedure (45-420 min); (3) duration of fluoroscopy (5-102 min); (4) number of necessary radio-frequency applications (1-48); and (5) cumulative energy per procedure. To ablate left-lateral pathways (n = 10) required fewer procedures, shorter duration per procedure, shorter fluoroscopy time, fewer current applications and less total energy than coagulation of right-sided pathways (n = 10). Those various parameters were greatest for ablation of septal and para-septal pathways (n = 9). Pathways which conducted only retrogradely (n = 15) were more difficult to ablate than those with anterograde conduction (n = 38). There were two complications. In one case a tension pneumothorax occurred after faulty puncture of the subclavian vein; in the other, the left ventricle was perforated causing an acute tamponade which required pericardiocentesis with subsequent suture closure of the perforation. It is concluded that, in principle, all accessory pathways, regardless of their conduction potential and site, can be ablated by a radio-frequency current. PMID:8472633

  19. Cancer of the accessory breast - a case report

    Breast neoplasm may develop in ectopically located glandular tissue. This paper presents an interesting and rare case of a 50-year-old female who despite regular mammography screening examination developed an invasive accessory breast cancer. Clinical examination revealed a 2 cm - tumour localized 4 cm below the left infra mammary fold. The lesion was immobile, the skin and the atrophic nipple were retracted, the tumour infiltrated the thoracic wall. Oligo biopsy and additional examinations showed an invasive stage IIIB ductal breast cancer (Bloom II, G-2). The receptor status was: ER(+), PGR(+), HER2(-). The increased level of cancer antigen 15.3 was found. The patient was submitted to pre-operative chemotherapy. She also underwent surgery and subsequently post-operative chemotherapy and radiotherapy. On the basis of the presented case, it could be concluded that the accessory mammary glands are out of the image of screening breast examinations. Accessory breast cancer is usually diagnosed by clinical examination and ultrasonography. Preventive resection of accessory breast in women at high risk of developing breast cancer can be considered as the treatment of choice in most patients. (authors)

    Miller, J.H.; Greenfield, L.D.; Wald, B.R.

    1982-02-01

    Four children with acute leukemia and surgically documented candidiasis of the liver and/or spleen were examined with a combination of diagnostic imaging modalities including /sup 99/mTc-sulfur colloid and /sup 67/Ga-citrate scintigraphy, gray-scale ultrasound, and body computed tomography (CT). Abnormalities were detected in every individual examined. /sup 99/mTc-sulfur colloid scintigraphy revealed cold areas in the liver or spleen. With /sup 67/Ga scintigraphy, these areas were cold in some individuals and hot in others. Gray-scale ultrasound demonstrated hypoechoic lesions with central areas of increased echogenicity in hepatic involvement, and hypoechoic replacement of the spleen in splenic involvement. CT in one patient revealed low-density areas without contrast enhancement within the hepatic parenchyma and unsuspected renal involvement.

  5. CT findings in children with blunt trauma in the spleen

    We evaluated CT findings in 19 children with blunt injuries in the spleen. CT demonstrated laceration of the spleen in 7 children, rupture of the spleen in 7, and splenic hematoma in 5. Leakage of the contrast medium was observed in 3 children, of whom 1 was treated by arterial embolization. Laparotomy was performed in 3 children (15.8%) other than the 3 showing contrast medium leakage; hemostasis by compression was performed in 1 with laceration, and splenectomy in 2 with rupture. Late splenic rupture or abscess did not occur in any child. One child (5.3%) died of complicating injuries. Many of children with blunt splenic injuries can be successfully treated with conservative treatment, and CT scanning is useful for evaluating the degree of splenic injuries and complicating injuries.

  6. Littoral-cell angioma of the spleen: A case report

    2007-01-01

    Littoral-cell angioma (LCA) is a primary splenic vascular tumor that arises from the normal littoral cells lining the sinus channels of the splenic red pulp. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 76-year-old man with a 2-wk history of weight loss, abdominal pain and changes in bowel habits was admitted to our hospital.Imaging studies (CT and MRI) showed multiple lesions in the spleen. Splenectomy was performed. Lining cells were positive for CD31/CD68 markers. Our case was associated with a serrated colonic adenoma. LCA is a benign vascular tumor of the spleen that needs to be included in the differential diagnosis of multiple splenic nodules.

    AIM: To evaluate the clinical application of serial operations with preservation of spleen. METHODS: Serial operations with preserving spleen were performed on 211 cases in our hospital from 1980 to 2000.The patient's age ranged from 13 to 56 years, averaging 3years. Diseases included splenic injury in 171 cases, portal hypertension in 9 cases, splenic cyst in 10 cases, and the lesion of pancreatic body and tail in 21 cases. RESULTS: All the cases were cured, and 129 patients were followedup from 3 months to 3 years with the leukocyte phagocytosis test, detection of immunoglubin, CT, 99mTc scanning and ultrasonogrsphy. The results were satisfactory. CONCLUSION: The operations with preserving spleen were safe, feasible, and worth of clinical application.

  8. Human spleen microanatomy: why mice do not suffice.

    Steiniger, Birte S

    2015-07-01

    The microanatomical structure of the spleen has been primarily described in mice and rats. This leads to terminological problems with respect to humans and their species-specific splenic microstructure. In mice, rats and humans the spleen consists of the white pulp embedded in the red pulp. In the white pulp, T and B lymphocytes form accumulations, the periarteriolar lymphatic sheaths and the follicles, located around intermediate-sized arterial vessels, the central arteries. The red pulp is a reticular connective tissue containing all types of blood cells. The spleen of mice and rats exhibits an additional well-delineated B-cell compartment, the marginal zone, between white and red pulp. This area is, however, absent in human spleen. Human splenic secondary follicles comprise three zones: a germinal centre, a mantle zone and a superficial zone. In humans, arterioles and sheathed capillaries in the red pulp are surrounded by lymphocytes, especially by B cells. Human sheathed capillaries are related to the splenic ellipsoids of most other vertebrates. Such vessels are lacking in rats or mice, which form an evolutionary exception. Capillary sheaths are composed of endothelial cells, pericytes, special stromal sheath cells, macrophages and B lymphocytes. Human spleens most probably host a totally open circulation system, as connections from capillaries to sinuses were not found in the red pulp. Three stromal cell types of different phenotype and location occur in the human white pulp. Splenic white and red pulp structure is reviewed in rats, mice and humans to encourage further investigations on lymphocyte recirculation through the spleen. PMID:25827019

  9. Effect of ionizing radiation on cell death in frog spleen

    It was studied the number of dead cells in frog spleen by means of coloration with trypan blue which allowed to estimate last stage of apoptosis dead of cells.The investigated frogs (Rana arvalis) were caught in september 1997 at radionuclide contamination territory (the Gomel Region, the Khojniki District). Control animals were caught in village Ratamka of the Minsk District. The percent of dead cells was less in control group in 1,5 times. Under additional irradiation (2 Gy) the number of dead cells in spleen also differs significantly in the investigated and control groups

    2007-01-01

    AIM: To identify the difference in gene expression of microphage (Mφ) between normal spleen and portal hypertensive spleen using cDNA microarrays and find new gene functions associated with hypersplenism in portal hypertension.METHODS: The Biostar-H140s chip containing 14112 spots of cDNAs were used to investigate the difference of the expression. The total RNA extracted from macrophages isolated from both normal spleen and portal hypertensive spleen was reversely transcribed to cDNA with the incorporation of fluorescent (cy3 and cy5) labeled dCTP to prepare the hybridization probes.After hybridization, the gene chip was scanned for the fluorescent intensity. The differentially expressed genes were screened. That was repeated three times,and only the genes which had differential expression in all three chips were considered to be associated with hypersplenism in portal hypertension.RESULTS: Eight hundred and ninety-six, 1330 and 898 genes were identified to be differentially expressed in three chips, respectively. One hundred and twenty-one genes (0.86%) were identified to be differentially expressed in all three chips, including 21 up-regulated genes and 73 down-regulated genes. The differentially expressed genes were related to ionic channel and transport protein, cyclin, cytoskeleton, cell receptor, cell signal conduct, metabolism, immune, and so on. These genes might be related to the hypersplenism in portal hypertension.CONCLUSION: The investigations based on cDNA microarray can screen differentially expressed genes of macrophages between normal spleen and portal hypertensive spleen, thus may provide a new idea in studying the pathogenesis of hypersplenism in portal hypertension.

    2011-06-01

    Full Text Available Benzalkonium chloride (BAC is a frequently used disinfectant and its most well-known side effect is contact dermatitis. In this report, two children who had vesicular dermatitis, headache, lethargy, fever and encephalopathy mimicking Herpes zoster encephalitis were presented. Their consciousness level improved on the second day. From the medical history it was understood that the mother had applied 20% BAC solution to the scalps of two children. The aim of the presentation of this report is to draw attention to the fact that BAC application to the scalp for treating pediculosis capitis may resemble the herpes encephalitis clinical picture.

    2005-01-01

    Actinomycosis is a rare, chronic, spreading, suppurative,granulomatous and fibrosing infection. Actinomyces are normal inhabitants of the oral cavity and gastrointestinal tract. They rarely cause disease and are seldom reported as pathogens. Herein, we reported on a 69-year-old male patient who had undergone Whipple's operation due to ampulla Vater carcinoma, and became infected with actinomycosis at the pancreaticojejunostomy, which mimicked a recurrent malignancy. He was treated with radical resection of the mass at the pancreaticojejunostomy and had an uneventful postoperative course.

  14. Hypertrophic Nonunion Humerus Mimicking an Enchondroma

    2014-01-01

    Full Text Available Introduction. Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur. Case Report. We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma. The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis was diagnosed conclusively to be a hypertrophic nonunion. Discussion. Enchondromas are often incidentally diagnosed benign tumours. It is however not common to misdiagnose a hypertrophic nonunion to be an enchondroma. We present this case to highlight the unique diagnostic dilemma the treating team had to face.

  15. Pulmonary lesions mimicking pericardial effusion on ultrasonography

    Two children with right middle lobe lesions mimicking pericardial effusion on ultrasonography are presented. They were admitted with fever and chest radiographs showed atelectasis or consolidation of the middle lobe of the right lung along the right heart border. A low-echogenic layer suggesting pericardial fluid was seen on ultrasonography, but with a spatial distribution closely corresponding to the lesions seen on the chest radiographs. If the possibility that a lung lesion adjacent to the heart can simulate pericardial fluid on ultrasonography is kept in mind, the correct diagnosis should not be difficult to make. (orig.)

    Di Bisceglie, A M; Hoofnagle, J H

    1990-01-01

    Southern blot analysis of splenic DNA from three patients with chronic hepatitis B revealed the presence of replicative intermediate forms of viral DNA. Hepatitis B viral RNA was detected in splenic RNA from two cases. Thus, hepatitis B virus appears to replicate in the human spleen, although at a lower level than in the liver.

    2000-05-01

    AIM: The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS: Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the study. We used a scoring system to grade the scintigraphic abnormalities. The patients' symptoms and scintigraphic findings were recorded. RESULTS: Though focally increased radiopharmaceutical uptake was observed in all symptomatic accessory naviculars, half of the asymptomatic accessory navicular bones had the same manifestations. The scoring system was of no value in differentiating symptomatic from asymptomatic accessory navicular bones. CONCLUSION: Bone scintigraphy is a sensitive but not a specific tool for diagnosing a symptomatic accessory navicular. Chiu, N.-T. (2000)

  3. Aspiration biopsy of mammary analogue secretory carcinoma of accessory parotid gland: another diagnostic dilemma in matrix-containing tumors of the salivary glands.

    Levine, Pascale; Fried, Karen; Krevitt, Lane D; Wang, Beverly; Wenig, Bruce M

    2014-01-01

    Mammary analogue secretory carcinoma (MASC) is a newly described rare salivary gland tumor, which shares morphologic features with acinic cell carcinoma, low-grade cystadenocarcinoma, and secretory carcinoma of the breast. This is the first reported case of MASC of an accessory parotid gland detected by aspiration biopsy with radiologic and histologic correlation in a 34-year-old patient. Sonographically-guided aspiration biopsy showed cytologic features mimicking those of low-grade mucoepidermoid carcinoma, including sheets of bland epithelial cells, dissociated histiocytoid cells with intracytoplasmic mucinous material, and spindle cells lying in a web-like matrix. Histologic sections showed a circumscribed tumor with microcystic spaces lined by bland uniform epithelial cells and containing secretory material. The tumor cells expressed mammaglobin and BRST-2. The cytologic features, differential diagnosis, and pitfalls are discussed. The pathologic stage was pT1N0. The patient showed no evidence of disease at 1 year follow-up. PMID:22807408

    2015-12-01

    Inflammatory myofibroblastic tumors (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior. This article describes an unusual case of IMT mimicking apical periodontitis in the mandible of a 42-year-old man. At first presentation, the patient showed spontaneous pain and percussion pain at teeth #28 to 30, which continued after initial endodontic treatment. Panoramic radiography revealed a radiolucent lesion at the site. Cone-beam computed tomographic imaging showed osteolytic lesions, suggesting an aggressive neoplasm requiring incisional biopsy. Histopathological examination indicated an IMT. The lesion was removed en bloc under general anesthesia, and the patient manifested no clinical evidence of recurrence for 24 months. Lesions of nonendodontic origin should be included in the differential diagnosis of apical periodontitis. Every available diagnostic tool should be used to confirm the diagnosis. Cone-beam computed tomographic imaging is very helpful for differential diagnosis in IMTs mimicking apical periodontitis. PMID:26602450

    2014-01-01

    Full Text Available Phishing is process of steeling valuable information such as ATM pins, Credit card details over internet. Where the attacker creates mimicked web pages from the legitimate web pages to fool users. In this paper, we propose an effective anti-phishing solution, by combining image based visual similarity based approach to detect plagiarized web pages. We used effective algorithms for our detection mechanism, speeded up Robust Features (SURF algorithm in order to generate signature based on extracting stable key points from the screen shot of the web page. When a legitimate web page is registered with our system, this algorithm applied on that web page in order to generate signatures, and these signatures are stored in the database for our trained system. When there is a suspected web page, this algorithm is applied to generate both the signatures of the suspected page and is verified against our database of corresponding legitimate web pages. Our results verified that our proposed system is very effective to detect the mimicked web pages with minimal false positives

    Das, Somdipto; Nayak, Umanath K; Buggavetti, Rahul; Sekhar, Shobana

    2016-05-01

    The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry. PMID:26851989

  8. Accessory Nerve Schwannoma Containing Multiple Calcifed Foci: Unusual Presentation

    Leila Aghaghazvini

    2009-01-01

    Full Text Available "nIntroduction: Schwannomas are benign neural tumors which arise from the nerve sheath. Schwannomas of the accessory nerve are rare lesions. The clinical presentation of cranial nerve XI schwannomas relates to their location and extent: intracranial, jugular foramen, upper neck, or cervical spine. The extra cranial form is the least common reported. Calcified accessory schwannoma is rare. These lesions most often occur in the third to sixth decades of life. These tumors are slightly more common in women. "nCase presentation: We present a 37-year-old woman with a painless right posterior neck space mass which gradually appeared during one year. Except for mild numbness of the overlying skin of the mentioned mass, there were no other associated symptoms. Examination confirmed a 25 × 18mm, firm, mobile, non tender lump in the right posterior neck. Ultrasonography revealed a 30×20 mm hypo-echoic mass with multiple calcified foci and in color Doppler mild vascularity was detected. On contrast-enhanced CT scan of the neck a 30×18mm heterogeneous enhancing mass with multiple calcified foci (on non contrast cuts was found posterior to the neck vessels and had displaced them anteriorly. No surrounding fat stranding or any other gross pathology was evident in the other neck spaces. "nAccording to the above findings, lymphadenopathy due to TB or less possibly, fungal infection, hemangioma, lymphangiomam, schwannoma were our differential diagnosis. Mass resection and histopathology revealed schwannoma of the accessory nerve with an unusual calcification presentation. No evidence of recurrence was detected after one year. "nDiscussion: The clinical presentation of cranial nerve XI Schwannomas relates to their location and extent. The interesting point of this case was the unusual manifestation of accessory nerve schwannoma, not only because of its rarity but also because of its unusual calcification presentation and symptom-free appearance.

  10. Primary Angiosarcoma of the Spleen: An Oncological Enigma

    Myoteri Despoina

    2014-01-01

    Full Text Available Introduction. Primary splenic angiosarcoma is an extremely unusual neoplasm originating from sinusoidal vascular endothelium. Surgical extirpation is the mainstay of treatment of this highly malignant disease. Case Presentation. An 82-year-old woman was admitted with left pleural effusion and a palpable left upper quadrant abdominal mass, secondary to splenomegaly by two large splenic tumors. Classic open splenectomy was performed and angiosarcoma of the spleen was the final histopathological diagnosis, which was primary since no other disease site was revealed. Discussion. The incidence of the disease is 0.14–0.23 cases per million, with slight male predominance. Etiology is not established and clinical presentation may confuse even experienced physicians. Imaging modalities cannot differentiate the lesion from other vascular splenic neoplasms and the correct diagnosis is mainly set after histopathological examination of the resected spleen. As with other sarcomas, surgery is the only curative approach, while chemo- and radiotherapy have poor results. Prognosis remains dismal.

  11. A map of sphingosine 1-phosphate distribution in the spleen

    Ramos-Perez, Willy D.; Fang, Victoria; Escalante-Alcalde, Diana; Cammer, Michael; Schwab, Susan R.

    2015-01-01

    Despite the importance of signaling lipids, many questions remain about their function because we have few tools to chart lipid gradients in vivo. Here we describe a sphingosine 1-phosphate (S1P) reporter mouse, and use this mouse to define S1P distribution in the spleen. Surprisingly, the presence of blood does not predict the concentration of signaling-available S1P. Large areas of the red pulp are S1P-low, while S1P can be sensed by cells inside the white pulp near the marginal sinus. Lipid phosphate phosphatase 3 maintains low S1P concentrations in the spleen, and enables efficient marginal zone B cell shuttling. The exquisitely tight regulation of S1P availability may explain how a single lipid can simultaneously orchestrate many immune cell movements. PMID:26502404

    Reciprocal interations between hemopoietic stromal cells and immature hemopoietic cells in human spleens obtained from 20 fetuses of 10-28 weeks gestation were observed by transmission electron microscopy and scanning electron microscopy.The close association of stromal cells with immature hemopoietic cells was confirmed under the electron microscope and a preasumptive HIM(Hemopoietic inductive mocroenvironment) was visualized.In regions of immature hemopoietice cell-reticular cell,endothelial cell,macrophage and interdigitating cell contact,some communicating structures were found between the plasma membranes of adjacent cells.moreovcer,the cytoplasm of these four stromal cells were full of various kinds of organelles.These results suggest that reticular cells,endothelial cells,macrophages and interdigitating cells are component parts of the HIM of human fetal spleen and that these cells have a nurturing function in relation to hemopoietic cells.

  13. Inflammatory pseudo tumor of the spleen. Radiologic findings

    The inflammatory splenic pseudo tumor is an uncommon benign lesion of unknown etiology that usually is detected incidentally in patients being examined for other disorders. We present the ultrasound, computed tomography (CT) and magnetic resonance (MR) findings in two patients (a 56-year-old woman and 67-year-old man) with inflammatory pseudo tumor of the spleen. Ultrasound images of the inflammatory splenic pseudo tumor show a hypoechoic mass with or without calcifications. In CT, the mass presents a low attenuation that is slightly enhanced by intravenous injection of an iodinated contrast medium. MR images show an isointense spleen in T1-weighted spin-echo sequences that is hypointense in T2-weighted sequences. The differential diagnosis should consider other more common splenic masses. but the definitive diagnosis can not be based on imaging methods alone. In the both cases, the final diagnosis was reached after splenectomy and pathological study. (Author) 8 refs

    A SPECT methodology for liver/spleen imaging is discussed with emphasis on quality control, conduct of study-imaging conduct of study-reconstruction. Normal transaxial anatomy and common artefacts which can masquerade as intrinsic disease are described. Structured artefacts which can be mistaken for real anatomy may occur from three general sources: camera field non-uniformities; statistical noise; attenuation. Each of these has a characteristic appearance which should alert the viewer to their possible presence

  17. Pancreatitis-associated fluid collections involving the spleen

    The clinical and radiographic features of 2 patients with dissecting pancreatitis-associated fluid collections involving the spleen are described. A typical appearance of left upper quadrant fluid collection lateral to the splenic pulp was observed by ultrasonography (US) or computed body tomography (CBT). Although these findings are nonspecific, a left upper quadrant fluid collection may be characterized definitively by US/CBT-guided needle aspiration. (orig.)

  18. Pelvic-peritoneal tuberculosis mimicking ovarian cancer

    Pelvic-peritoneal tuberculosis is a common extrapulmonary site in young females mimicking an advanced ovarian malignancy. We present 2 cases with the classical triad of advanced-stage ovarian carcinoma-ascites, abdominopelvic masses and elevated serum CA-125 levels. Laparoscopic examination revealed peritoneal nodules which on biopsy showed granulomatous inflammation and no malignant cells. Patients were started on anti-tuberculous therapy and on follow-up their symptoms as well as CA-125 levels normalized. Medical awareness of peritoneal tuberculosis is lacking and many young women with this disease undergo unnecessary extended surgery. Diagnostic laparoscopy combined with peritoneal biopsy seems to be a sufficient and safe method to provide a definitive diagnosis for this curable infection. If left untreated, the disease may disseminate and result in significant organ dysfunctions particularly infertility. (author)

    Only about 1% of marine bacteria have been brought into culture using traditional techniques. The purpose of this study was to investigate if mimicking the natural bacterial environment can increase culturability.We used marine substrates containing defined algal polymers or gellan gum as...... solidifying agents, and enumerated bacteria from seawater and algal exudates. We tested if culturability could be influenced by addition of quorum sensing signals (AHLs). All plates were incubated at 15°C. Bacterial counts (CFU/g) from algal exudates from brown algae were highest on media containing algal...... polymers. In general, bacteria isolated from algal exudates preferred more rich media than bacteria isolated from seawater. Overall, culturability ranged from 0.01 to 0.8% as compared to total cell count. Substitution of agar with gellan gum increased the culturability of seawater bacteria approximately...

    2015-10-01

    Full Text Available Eventration of diaphragm is a condition in which there is abnormal elevation of the diaphragm as a result of thinning of muscular layer. It can be congenital as well as acquired. It is more common left sided. Herniation of the abdominal contents can be there. Clinical manifestations range from asymptomatic to life threatening respiratory distress requiring mechanical ventilator support. Ultrasound provides valuable information regarding the integrity of the diaphragm. Other imaging modalities include fluoroscopy, CT and MRI that provide valuable information when diagnosis is in doubt. We are presenting a case report of 25-year-old male with eventration of left hemidiaphragm mimicking as cavity. After taking detail history, examination and proper investigations we finally reached to this diagnosis.

  1. High-altitude cerebral oedema mimicking stroke.

    Yanamandra, Uday; Gupta, Amul; Patyal, Sagarika; Varma, Prem Prakash

    2014-01-01

    High-altitude cerebral oedema (HACO) is the most fatal high-altitude illness seen by rural physicians practising in high-altitude areas. HACO presents clinically with cerebellar ataxia, features of raised intracranial pressure (ICP) and coma. Early identification is important as delay in diagnosis can be fatal. We present two cases of HACO presenting with focal deficits mimicking stroke. The first patient presented with left-sided hemiplegia associated with the rapid deterioration in the sensorium. Neuroimaging revealed features suggestive of vasogenic oedema. The second patient presented with monoplegia of the lower limb. Neuroimaging revealed perfusion deficit in anterior cerebral artery territory. Both patients were managed with dexamethasone and they improved dramatically. Clinical picture and neuroimaging closely resembled acute ischaemic stroke in both cases. Thrombolysis in these patients would have been disastrous. Recent travel to high altitude, young age, absence of atherosclerotic risk factors and features of raised ICP concomitantly directed the diagnosis to HACO. PMID:24671373

    2015-12-15

    Differential diagnosis between spinal metastasis and infectious spondylodiscitis is one of the occasional challenges in daily clinical practice. We encountered an unusual case of spinal metastasis in a 75-year-old female breast cancer patient that mimicked infectious spondylodiscitis. Magnetic resonance imaging (MRI) showed diffuse bone marrow infiltrations with paraspinal soft tissue infiltrative changes in 5 contiguous cervical vertebrae without significant compression fracture or cortical destruction. These MRI findings made it difficult to differentiate between spinal metastasis and infectious spondylodiscitis. Infectious spondylodiscitis such as tuberculous spondylodiscitis was regarded as the more appropriate diagnosis due to the continuous involvement of > 5 cervical vertebrae. The patient's clinical presentation also supported the presumptive diagnosis of infectious spondylodiscitis rather than spinal metastasis. Intravenous antibiotics were administered, but clinical symptoms worsened despite treatment. After pathologic confirmation by computed tomography-guided biopsy, we were able to confirm a final diagnosis of spinal metastasis.

  3. Inflammatory pseudotumor of the spleen: A case report

    Selda SEÇKİN

    2008-05-01

    Full Text Available Inflammatory pseudotumors, also known as inflammatory miyofibroblastic tumors, are rare benign tumors of the spleen. The diagnosis of these tumors may be difficult, because they simulate some hematopoetic malignancies, leiomyosarcomas, inflammatory malignant fibrous histiocytoma and inflammatory fibrosclerosing lesions. They frequently occur at lung. But they are reported at gastrointestinal system, orbit, liver, bladder, lymph nodes, heart, brain, mesentery, omentum and spleen. Histologically they are composed of an admixture of cells like lymphocytes, plasma cells, foamy histiocytes, neutrophils and eosinophils with fibrosis, sclerosis and plump fibroblasts. Immunohistochemical stains show diffuse staining of tumor cells with vimentin and less common with myogenic markers like smooth muscle actin, muscle specific actin and desmin. CD 68 and focal cytokeratin immunoreactivity are found. We present a case of 53 year old female. Laboratory investigations were normal. Abdominal ultrasonography showed a heterogenous, hypoechoic nodular mass measuring 30x27 mm in the superior portion of the spleen parenchyma. Splenectomy was performed. Histologically the lesion was composed of inflammatory cells and miyofibroblasts. The case was diagnosed as inflammatory pseudotumor (Inflammatory miyofibroblastic tumor with histological and immunohistochemical findings.

  4. The spleen and skin wound healing in Xenopus adults.

    2016-07-01

    In most vertebrates, the regenerative capacity to restore lost/damage tissues to original structure and functionality decreases at some time during ontogenesis. To evaluate the role of the acquired immunity in the decline of regenerative potential, we examined the cellular responses elicited in the spleen during skin repair in Xenopus adults. Modifications in the architecture were found to be induced and were remarkable 14 days postinjury when the spleen increased significantly in size. In white pulp, the periarteriolar lymphoid sheaths were associated with follicles having central light zones, morphologically similar to germinal centers. With the progress of healing, pigment-containing cells were seen to accumulate in both white and red pulp regions. Moreover, compared to controls, the cells immunoreactive to anti-cytokines (TNF-α, TGF-β1) and -iNOS increased from the first days after wounding. The 14th day, the positive cells formed a dense network of reticular cells in central regions of lymphoid follicles and more frequent reactive leukocytes were detected within the red pulp. A higher number of lymphoid cells immunostained with anti-CD3ε were also observed in the perifollicular zone. The results suggest that the spleen of adult frogs is involved in skin wound healing with the expansion of lymphoid compartments. J. Morphol. 277:888-895, 2016. © 2016 Wiley Periodicals, Inc.

  5. Membranoproliferative Glomerulonephritis and Inflammatory Pseudotumour of the Spleen

    U. Hadimeri

    2013-02-01

    Full Text Available Inflammatory pseudotumour is a rare condition that can affect various organs. The clinical and histologic appearance of the pseudotumour may mimic haematological, lymphoproliferative, paraneoplastic or malignant processes. A previously healthy 39-year-old man presented with nephrotic syndrome. He had a history of headaches, nausea and swollen ankles. Computed tomography of the abdomen revealed a 6-cm mass in the spleen. Following a renal biopsy, a diagnosis of membranoproliferative glomerulonephritis (MPGN type I was made. Splenectomy was performed and the examination revealed a mixed population of lymphocytes with predominantly T-cells, B-cells and lymphoplasmacytoid cells. Immunostaining confirmed that the small cells were mostly T-cells positive for all T-cell markers including CD2, CD3, CD4, CD5, CD7 and CD8. A diagnosis of inflammatory pseudotumour was established. The removal of the spleen was followed by remission of glomerulonephritis, but it was complicated by a subphrenic abscess and pneumonia. This association between an inflammatory pseudotumour of the spleen and MPGN has not been previously described. Abnormal immune response due to the inflammation leading to secondary glomerulonephritis might be the main pathogenic mechanism.

    Spontaneous splenic rupture (SSR) is a rare condition. It may be an idiopathic event or may occur secondary to a pathological condition of the spleen. Systemic amyloidosis is characterized by the extracellular deposition of amyloid proteins in one or more organs. The spleen can be affected in 41% of patients. Amyloidosis and consequently, splenic rupture may occur as a complication of amyloid infiltration. We present the case of a 61-year-old male with abdominal pain and hypotension. There were peritoneal signs during physical examination and falling hematocrit was reported in the laboratory tests. The patient was suspected of having an aortic dissection. Thoraco-abdominal computed tomography (CT) angiogram was negative and ultrasonography revealed splenic rupture and free fluid in the abdominal cavity. The patient underwent laparotomy when found hemoperitoneum as a consequence of splenic rupture. The subsequent histopathological report of the spleen revealed amyloidosis. Thus, in patients with abdominal pain and hypotension, we should suspect the possibility of a spontaneous splenic rupture, even without trauma or infection history. (author)

    Abscess of the spleen is a rare discovery, with about 600 cases in the international literature so far. Although it may have various causes, it is most usually associated with trauma and infections of the spleen. The latter are more common in the presence of a different primary site of infection, especially endocarditis or in cases of ischemic infarcts that are secondarily infected.Moreover, immunosuppression is a major risk factor.Clinical examination usually reveals a combination of fever, left-upper-quadrant abdominal pain and vomiting.Laboratory findings are not constant. Imaging is a necessary tool for establishing the diagnosis, with a choice between ultrasound and computed tomography.Treatment includes conservative measures, and surgical intervention. In children and in cases of solitary abscesses with a thick wall, percutaneous catheter drainage may be attempted. Otherwise, splenectomy is the preferred approach in most centers. Here, we present three cases of splenic abscess. In all three,splenectomy was performed, followed by rapid clinical improvement. These cases emphasize that current understanding of spleen abscess etiology is still limited,and a study for additional risk factors may be necessary.

    2012-01-01

    Full Text Available Aim : In children suffering from severe hepatosplenic schistosomiasis, the surgical protocol includes splenectomy and autoimplantation of spleen morsels in the major omentum, which has the potential of reducing the overwhelming postsplenectomy infection (OPSI. The purpose of the study was to evaluate the remaining splenosis, with the mean postoperative followup of 12.1 ± 5.6 years; to compare the efficacy of the 2 evaluation tools. Materials and Methods : Nineteen patients underwent, when they were children, portal decompression and autoimplantation of spleen. After a mean age of 23.4 ± 5.3 years, they were investigated regarding the number of infections and OPSI. They had undergone hepatosplenic scintigraphy with labeled colloidal SnTc 99m and abdominal ultrasound. It was considered efficient splenosis when the patients presented with 5 or more spleen nodules. The evaluation was performed by 3 observers. Results : None of the patients had increased infection rate or developed OPSI. Sixteen (84.2% presented efficient splenosis. Conclusions : The remaining postoperative splenosis was considered efficient in the majority of patients in the long-term followup; and nuclear medicine was considered the gold standard for splenosis evaluation.

    Animals modulate their courtship and territorial behaviors in response to olfactory cues produced by other animals. In rodents, detecting these cues is the primary role of the accessory olfactory system (AOS). We sought to systematically investigate the natural stimulus coding logic and robustness in neurons of the first two stages of accessory olfactory processing, the vomeronasal organ (VNO) and accessory olfactory bulb (AOB). We show that firing rate responses of just a few well-chosen mou...

    2001-01-01

    As of 1st October you can order and receive GSM accessories from the CERN stores like any other article. The CERN stores also manage GSM telephones but, for technical reasons, only the Labo Telecom shop (Building 31, Room S026) is able to make the standard sales, repairs and exchanges for authorised persons with a CERN subscription. Labo Telecom will thus become a specialist shop, open from 11 a.m. to 12 a.m., and will apply the usual rules and authorisation procedures of the stores. The paper form for requests for GSM subscriptions is being computerized and will be available on EDH in the near future.

  1. Accessory breast tissue in axilla masquerading as breast cancer recurrence

    Goyal Shikha

    2008-01-01

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

  2. Management of Blunt Trauma to the Spleen (Part 1

    Seyed Abbas Banani

    2010-06-01

    Full Text Available AbstractSpleen is the most frequent solid organ to be injured in bluntabdominal trauma. Considering its important role in providingimmunity and preventing infection by a variety of mechanisms,every attempt should be made, if possible, to salvagethe traumatized spleen at any age particularly in children. Afterprimary resuscitation, mandatory requirements for nonoperativemanagement include absence of homodynamic instability,lack of associated major organ injury, admission inthe intensive care unit for high-grade splenic injury and in theward for milder types with close monitoring. About two thirdof the patients would respond to non-operative management.In most patients, failure of non-operative measures usuallyoccur within 12 hours of management. Determinant role ofabdominal sonography or computed tomography, and in selectedcases, diagnostic peritoneal lavage, for appropriate decisioncannot be overemphasized. However, the high status ofclinical judgment would not be replaced by any paraclinicalinvestigations. When operation is unavoidable, if possible,spleen saving procedures (splenorrhaphy or partial splenectomyshould be tried. In case of total splenectomy, autotransplantation,preferably in the omental pouch, may lead toreturn of immunity, at least partially, to prevent or reduce thechance of subsequent infection. Although total splenectomywith autograft is immunologically superior to total splenectomy-only procedure, these patients should also be protectedby vaccination and daily antibiotic for certain period of time.The essential steps for prevention of overwhelming infectionafter total splenectomy are not only immunization and administrationof daily antibiotic (up to 5 years of age or one year inolder children, but include education and information aboutthis dangerous complication. When non-operative managementis successful, the duration of activity restriction (inweeks is almost equal to the grade of splenic injury plus 2.Iran J Med Sci 2010

    2009-01-01

    AIM: To study the liver and spleen volume variations in hepatic fibrosis patients at different histopathological stages.METHODS: Multidetector computed tomography (MDCT) scan was performed in 85 hepatic fibrosis patients. Liver volume (LV) and spleen volume (SV) were measured. Fifteen healthy individuals served as a control group (S0). The patients were divided into stage 1 (S1) group ( n = 34), stage 2 (S2) group ( n = 25), stage 3 (S3) group ( n = 16), and stage 4 (S4)group ( n = 10) according to their histopathological stage of liver fibrosis.RESULTS: The LV and standard LV(SLV)had a tendency to increase with the severity of fibrosis, but no statistical difference was observed in the 5 groups (LV: F = 0.245, P = 0.912; SLV: F = 1.902,P = 0.116). The SV was gradually increased with the severity of fibrosis, and a statistically significant difference in SV was observed among the 5 groups( P < 0.01). The LV/SV ratio and SLV/SV ratio were gradually decreased with the aggravation of hepatic fibrosis, and statistically significant differences in both LV/SV and SLV/SV were found among the 5 groups ( P< 0.01).CONCLUSION: The absence of obvious LV reduction in patients with chronic liver disease may be a morphological index of patients without liver cirrhosis. The SV is related to the severity of fibrosis, and the spleen of patients with advanced fibrosis is enlarged evidently. The LV/SV ratio and SLV/SV ratio are of a significant clinical value in the diagnosis of advanced liver fibrosis.

    Mucormycosis is an uncommon and frequently fatal fungal infection. It characteristically affects patients with diabetes mellitus or patients with severe immunosuppression. The hallmark of mucormycosis infection is tissue infarction and vascular invasion. We present clinical data and imaging studies of a 16 year-old child with acute lymphoblastic leukemia complicated by disseminated mucormycosis resulting in a pseudoaneurysm of the spleen. This was successfully managed by a combination of systemic antifungal therapy (Amphotericin B) and surgery (splenectomy). This entity has not been described in the literature. (orig.)

  5. Forest haulage accessories for agricultural tractors in 1995

    This bulletin is a review of hydraulic timber cranes, forest trailers and skidding grapples and winches available on the Finnish markets in autumn 1995 as accessories for mounting onto agricultural tractors. The information is mainly based on the responses of the manufacturers and distributors to a mail questionnaire. Ten producers make timber cranes and a total of 46 crane models are presented. Nearly all the cranes can be mounted onto either the 3-point hitching device, the connecting rail of a trailer/sled, or directly onto the tractor frame. The net lifting force of the cranes varies in between 19.9 - 40.0 kNm. The maximum reach of the cranes varies between 4.3 and 9.8 m. The mechanical twin-lever system has almost entirely replaced the conventional six-lever operating type. Electro-hydraulic pre-control is included in the accessories available for many of the cranes. There are twelve producers and 37 models of forestry trailers, with eight including power transmission. All these trailers are of the bogie type. Their carrying capacity varies between 6 000 - 12 500 kilos. Five manufacturers produce six models of 3-point hitchable hydraulic skidding grabbles were listed. all are provided with a frame joint easing the job of grasping and skidding of timber. Skidding winches mountable onto the 3-point hitching device are of three producers and seven models. The tractive force varies between 28 and 60 kN. All are provided with a disc clutch

  6. The accessory coracobrachialis muscle: ultrasound and MR features

    To present the prevalence, clinical relevance, and ultrasound (US) and magnetic resonance imaging (MRI) appearances of the accessory coracobrachialis (ACB) muscle. We present an US prospective study of the ACB muscle over a 2-year period. Five of the eight patients with suspected ACB on US were subsequently examined by MRI. An ACB muscle was demonstrated by US in eight patients (eight shoulders), including seven females, one male, with mean age 39 years, over 770 (664 patients) consecutive shoulder US examinations referred to our institution yielding a prevalence of 1.04 %. In dynamic US assessment, one case of subcoracoid impingement secondary to a bulky ACB was diagnosed. No thoracic outlet syndrome was encountered in the remaining cases. MRI confirmed the presence of the accessory muscle in five cases. ACB muscle is a rarely reported yet not uncommon anatomic variation of the shoulder musculature encountered only in eight of 664 patients referred for shoulder US study. Its US and MRI appearance is described. One of our patients presented with subcoracoid impingement related to the presence of an ACB. (orig.)

  8. Digital dermatitis of the accessory digits of dairy cows

    Celso A. Rodrigues

    2010-03-01

    Full Text Available This report characterizes the digital dermatitis (DD lesions in the accessory digits of dairy cows and presents data on the applied therapy. Fifteen Holstein cattle with DD affecting the accessory digits of the hindlimbs from four dairy farms with previous history of DD were evaluated. Lesions were excised, the wounds were sutured, and a topical application of oxytetracycline powder covered by bandaging was associated with a single parenteral administration of long acting oxytetracycline IM (20mg/kg. Tissue samples were obtained for histopathology and transmission electronic microscopy (TEM. Lesions from all the animals were recuperated 15 days after surgical procedure. Overal, most DD lesions were papillomatous epidermal projections or wartlike verrucous lesions. Histopathologically, samples revealed hyperplasia of epidermis with hyperkeratosis, several mitoses in the stratum basale and elongated rete ridges in the superficial and middle dermis. TEM revealed long, thin spirochete-like bacteria. Morphologic features of lesions and its response to therapy were comparable to those described for DD.

  9. Behaviour of bentonite accessory minerals during the thermal stage

    Arcos, David; Bruno, Jordi [Enviros-QuantiSci, Barcelona (Spain); Benbow, Steven; Takase, Hiro [Quintessa Limited, Henley-on-Thames (United Kingdom)

    2000-03-15

    This report discusses in a quantitative manner the evolution of the accessory minerals in the bentonite as a result of the thermal event exerted by the spent fuel in the near field. Three different modelling approaches have been used and the results compared between them. The three different approaches have been calculated using two Differential Algebraic Equation (DAE) solver: DYLAN (Model-1) and the Nag DAE solver, d02ngf (Model-2) and the third approach (Model-3) using the last version of PHREEQC. The results from these calculations indicate the feasibility of the modelling approach to model the migration of bentonite accessory minerals and relevant aqueous species throughout the thermal gradient. These calculations indicate that the migration of quartz and quartz polymorphs is a lesser problem. The aqueous speciation of Ca in the bentonite pore water is fundamental in order to define the potential migration of anhydrite during the thermal stage. If CaSO{sub 4}(aq) is the predominant aqueous species, then anhydrite dissolves at the initial groundwater migration times through bentonite. However, if Ca{sup 2+} is considered to be the dominant Ca species at the bentonite pore water, then anhydrite migrates towards the clay/granite interface. This is the main difference in the chemical systems considered in the three model approaches used in this work. The main process affecting the trace mineral behaviour in bentonite is cation exchange. This process controls the concentration of calcium, which results in a direct control of the calcite precipitation-dissolution.

  10. Nipple adenoma arising from axillary accessory breast: a case report

    Shioi Yoshihiro

    2012-11-01

    Full Text Available Abstract Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the axillary accessory breast have very seldom been reported in the English literature. We report a case of nipple adenoma arising from axillary accessory breast including clinical and pathological findings. An 82-year-old woman presented with the complaint of a small painful mass in the right axilla. Physical examination confirmed a well-defined eczematous crusted mass that was 8 mm in size. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Microscopic structural features included a compact proliferation of small tubules lined by epithelial and myoepithelial cells, and the merging of glandular epithelial cells of the adenoma into squamous epithelial cells in the superficial epidermal layer. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for axillary tumor neoplasms.
