Although accessory spleen is a frequently encountered entity, accessory spleen in the greater omentum is rare. A 22-year-old woman presented with dull pain in the left upper abdomen. Cross-sectional imaging studies with 3-dimensional reconstruction suggested the presence of a huge tumor in the greater omentum that ...

Four dogs with an accessory spleen are described. The accessory spleens appeared as a round-to-triangular structure located in the perisplenic area. They were homogeneous and isoechoic with the adjacent spleen. Contrast-enhanced ultrasound was performed using a second generation microbubble ...

Here, we report a case of intrapancreatic accessory spleen confirmed by pathologic diagnosis and discuss its differential diagnosis and surgical management with a review of the literature.

According to autoptic studies, accessory spleens may be found in 10% to 15% of the population, in 1% to 2% they are located in the pancreatic tail. They thus have to be taken into account in the differential diagnosis of intra- and peripancreatic tumorous lesions. After splenorenal fusion, they can be found pararenally and retroperitoneally, and after ...

... of spleen, thymus and accessory sex glands. ... were not consistent for both sexes (kidney weights ... lesions observed in reproductive organs of mature ...

In two patients with recurrent immune thrombocytopenia, accessory splenic tissue was demonstrated by radionuclide imaging following administration of indium 111-labeled autologous platelets. In one of these patients, no accessory splenic tissue was seen on images obtained with technetium 99m sulfur colloid. This new technique provides a simple means for ...

A patient with a previous splenectomy presented with acute gastrointestinal bleeding. He was found to have a benign gastric ulcer, esophagogastric varices, and a mass indenting the gastric fundus. Abdominal computerized tomography and technetium liver-spleen scanning established the diagnosis of an accessory spleen as cause for the ...

Although the tail of the pancreas is the second most common site of an accessory spleen, intrapancreatic accessory spleen (IPAS) has rarely been noted radiologically. However, as the imaging techniques have recently advanced, IPAS will be more frequently detected as an incidental pancreatic nodule on CT or MRI. ...

Accessory spleens were sought in 28 patients who had undergone splenectomy for chronic idiopathic thrombocytopenic purpura (ITP), using a variety of techniques. Abdominal scintigraphy with autologous erythrocytes labeled with Tc-99m and opsonized with anit-D IgG (radioimmune method) proved to be most useful, clearly demonstrating one or more ...

The non traumatic surgical pathology of the spleen in childhood is reviewed. This pathology is rare and gives various and generally misleading symptoms. Part of this pathology is of congenital origin ie: torsion of ectopic spleen, multiple and accessory spleens, syndrome of polysplenia, splenogonadal fusion. The ...

A case report is presented of a 31-year old woman with a large abdominal mass. She had been struck in the left lower chest one year previously during an auto accident. Diagnostic techniques of abdominal radiography, spleen scintiscanning, and spleen angiography are described. At laparotomy a giant cyst of the spleen and two ...

We report a rare case of an epidermoid cyst originating from an intrapancreatic accessory spleen, in a 40-year-old Japanese man with no clinical symptoms. A cystic tumor in the pancreatic tail was detected incidentally by abdominal ultrasonography. The patient was referred to the KKR Tachikawa Hospital for further examination of the tumor. Preoperative ...

The spleen is the major accumulation of lymphoid tissue in the human body, an organ which prenatally produces and postnatally controls blood cells. Normally, a developed spleen lies in the upper left quadrant in parallel with the long axis of the 10th rib. It is a mesodermal derivate which first appears as a condensation of mesenchymal cells inside the ...

Accessory spleens (AS) may be formed during embryonic development when some of the cells from the developing spleen are deposited along the path from the midline, where the spleen forms, over to its final location on the left side of the abdomen. An accessory spleen is ...

OBJECTIVE: Combined use of low-mechanical-index technologies and non-air-filled contrast media allows real-time sonographic assessment of the spleen. This pictorial essay focuses on several aspects of contrast-enhanced sonography of the spleen, including examination technique, clinical indications, normal findings obtained through all vascular phases, ...

A renal mass was correctly identified with Tc-99m sulfur colloid liver-spleen scan and Tc-99m glucoheptonate scintigraphy while CT scan was misinterpreted as showing a hepatic lesion.

A patient undergoing evaluation for malignant melanoma was thought to have a metastatic process involving the anterior mediastinum, axilla, spleen, and possibly liver based on radiologic findings from positron emission tomography and computed tomography scans. The clinical picture did not corroborate this suspicion, and biopsies ultimately confirmed lymphangioma in the ...

A splenic space occupying lesion, in a 45-year-old woman, was negative in a Tc-99m-RBC spleen scan. A diagnostic splenectomy was performed and the lesion was found to be a vascular tumor, lately identified as littoral cell angioma. The histological and immunohistochemical findings are discussed in correlation with the imaging results. PMID:9397143

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 99mTc 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 ...

We report three cystic fibrosis (CF) patients with hypersplenism who underwent partial splenectomy. The postoperative course was uneventful in two patients; one patient developed a complication necessitating resection of the rest of the spleen. Haematological parameters improved and oesophageal varices regressed in all patients. On follow up, one patient showed a normal ...

Splenogonadal fusion (SGF) is a rare abnormality with two known types. In the continuous type, the spleen is connected to the gonad, and there are often limb defects, micrognathia, or other congenital malformations such as ventricular septal defect, anal atresia, microgastria, spina bifida, craniosynostosis, thoracopagus, diaphragmatic hernia, hypoplastic lung and abnormal ...

Adult (8-week-old) SJL mice reach a relatively low degree of tolerance when injected with aggregate free rabbit ..gamma..-globulin (RGG). To analyze this phenomenon, we first examined indirect plaque-forming responses (PFC) in terms of participation of accessory and thymus-derived cells. Double transfer experiments were used; accessory cells were removed ...

We present a case of intrapancreatic accessory splenic infarction in a 28-year-old woman. It was discovered during a workup for an acute right epigastric pain. Computed tomography imaging of abdomen demonstrated a hemorrhagic high attenuation with enhancing solid portion in the tail of pancreas. The clinical and radiological differential diagnosis included pancreatic mucinous ...

A 41-year-old woman with recurrent wide-QRS tachycardia is reported. Electrophysiologic findings were consistent with the diagnosis of a preexcited atrioventricular nodal reentrant tachycardia due to a bystander nodo-ventricular fiber. However, slow pathway ablation did not preclude tachycardia recurrence. A second electrophysiology study shed light on the correct mechanism and eventually a ...
