Despite the increased recognition of surgical problems related to cardiac catheterization, splenic abscess has not been perceived as a common complication. The authors encountered a case of splenic abscess following PTCA in a 61-year old male patient. The major symptom was insidious general malaise. Fever and tenderness in the left upper quadrant of the abdomen were the only positive physical findings. Gram positive anaerobic Streptococci intermedius was indentified as the pathogen in cultures of the ultrasonography-guided aspirate from the splenic abscess. Ultrasonography and abdominal CT scan were diagnostic of the splenic abscess. The patient recovered following a splenectomy.

Splenic abscess is an unusual condition usually seen in immunocompromised patients or associated with intravenous drug abuses. Several conditions including trauma, immunodeficiency, corticosteroid and/or immunosuppressive therapy and diabetes mellitus have been listed under the predisposing factors for a splenic abscess. Splenic abscess in a patient on hemodialysis is a rare but life-threatening condition if not corrected. We describe a case of splenic abscess with bacterial endocarditis on maintenance hemodialysis. He had staphylococcal septicemia secondary to bacterial endocarditis at the mitral valve from the dialysis accesssite infection. Although hematologic seeding from endocarditis has been the predisposing factor for splenic abscess, we postulate that access-site infections may predispose hemodialysis patients to splenic abscess. Splenic abscess may be considered as one of the causes when patients on hemodialysis develop unexplained fever.

Splenic pseudocyst is a rare disease associated with chronic and acute pancreatitis splenic pseudocyst is treated by distal pancreatectomy and splenectomy. A 47-year old woman with a 10-year history of alcohol abuse presented with epigastric and left upper quadrant pain of 3 days duration. Abdominal CT showed a 4.0x4.5 cm sized cystic lesion in the tail of the pancreas. Analgesics was administrated for the relief of abdominal pain. On the 4th hospital day, the patient complained more of left upper quadrant pain, so we took follow up CT scans. On follow up CT, one large splenic pseudocyst with size of 9.5x4.5x10.0 cm was noted. The patient was treated conservatively by percutaneous catheter drainage and discharged on the 13th hospital day. This case is the first case report of splenic pseudocyst treated conservatively, not by surgery in Korea.

To investigate the temporal progression of atherogenesis on the aorta and involvement of the monocyte-macrophage system in the liver and spleen, we fed 74 rabbits with high fat (14 or 7 gm+ACU-) and cholesterol (2 and 1+ACU-) diets for 4 to over 24 weeks. Using both light and electron microscopies, we found that the bro-fatty areas on the luminal surface of aortas was spread over along the eding time dependently. The fat deposits also in the liver and spleen worsened pending on the time of feeding the atherogenic diets. Not only nocyte-derived foam cells, but also parenchymatous cells in the liver and leen involved become fat-laden cells. According to these results, we propose at there are three stages: 1) the primary seeding, 2) the intermediate turing and 3) the advanced periods. These periods may play very important les in designing the management and treatment of atherosclerotic patients.

INTRODUCTIONSplenic abscess is an uncommon clinical problem. Traditionally, the "gold standard" treatment has been splenectomy. However, there is increasing use of non-operative treatments worldwide.

MATERIALS AND METHODSA 10-year (1996-2005) retrospective review of case records from a single centre (an 800-bed general hospital) was performed. Information regarding demographics, clinical presentation, aetiological agents and management was gathered and analysed.

RESULTSThere were 21 cases from 1996 to 2005. Nineteen (90%) had multiple abscesses. Disseminated melioidosis was the most common aetiological agent (15 cases, 71%). Only 3 patients underwent splenectomy. The remainder were treated conservatively with antibiotics. Almost all the patients (19, 90%) also suffered from diabetes mellitus.

CONCLUSIONSThe most common aetiological agent encountered was Burkholderia pseudomallei. Diabetes mellitus may be an important co-factor in the pathogenesis of splenic abscesses. The majority of our patients were managed conservatively and splenectomy was only occasionally required.

Portal annular pancreas is one of the pancreatic fusion anomalies in which the uncinate process of the pancreas extends to fuse with the dorsal pancreas by encircling the portal vein or superior mesenteric vein. We report two consecutive patients with portal annular pancreas. The first case is a 71-year-old male patient who underwent a pancreaticoduodenectomy for intraductal papillary mucinous neoplasm in the head of pancreas. His preoperative computed tomography scan showed the suprasplenic type portal annular pancreas. The second case is a 74-year-old female patient who underwent a laparoscopic anterior radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic body cancer. In operative finding, portal confluence (superior mesenteric vein-splenic vein-portal vein) was encased with the uncinate process of pancreas in both cases. Therefore, they required pancreatic division at the pancreatic neck portion twice. During the postoperative period, grade B and A, respectively, postoperative pancreatic fistulas occurred and were controlled by conservative management. Surgeons need to know about this rare pancreatic condition prior to surgical intervention to avoid complications, and to provide patients with well-designed, case-specific pancreatic surgery.

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 cystic neoplasm, pancreatic endocrine neoplasm, solid pseudopapillary tumor, ductal adenocarcinoma, and metastasis. A distal pancreatectomy was completed. The microscopic examination revealed heterotopic splenic tissue with infarction and her abdominal pain disappeared. In this case report, we first describe a symptomatic accessory splenic infarction which presented as a hemorrhagic mass in the tail of pancreas mimicking pancreatic neoplasm.

A 23-year-old man presented with abdominal pain after suffering blunt trauma caused by a seatbelt injury. His low platelet count of 137 × 10(9)/L was initially attributed to trauma and his underlying hypersplenism due to glucose-6-phosphate dehydrogenase (G6PD) deficiency. Despite conservative management, his platelet count remained persistently reduced even after his haemoglobin and clotting abnormalities were stabilised. After a week, follow-up imaging revealed an incidental finding of a pseudoaneurysm (measuring 9 mm × 8 mm × 10 mm) adjacent to a splenic laceration. The pseudoaneurysm was successfully closed via transcatheter glue embolisation; 20% of the spleen was also embolised. A week later, the platelet count normalised, and the patient was subsequently discharged. This case highlights the pitfalls in the detection of a delayed occurrence of splenic artery pseudoaneurysm after blunt injury via routine delayed phase computed tomography. While splenomegaly in G6PD may be a predisposing factor for injury, a low platelet count should arouse suspicion of internal haemorrhage rather than hypersplenism.
