Hemodynamics of small sclerosing hepatocellular carcinoma without fibrous capsule: evaluation with single-level dynamic CT during hepatic arteriography

The tumor drainage pathway of a hypervascular liver tumor without fibrous capsule was evaluated histologically and using single-level dynamic CT during hepatic arteriography (CTHA) in a case of sclerosing type of hepatocellular carcinoma. This tumor had a thin corona on CTHA, which represented drainage from the tumor sinusoids to the surrounding liver sinusoids. Additionally, the corona of the hypervascular tumor was thinner without than with the fibrous capsule.     

A rare cause of vaginal bleeding in a 7-month-old female infant

Ovarian sex cord stromal tumor (OSCST), sclerosing type, is an extremely rare ovarian tumor. Sex hormone production by OSCST can result in isosexual or heterosexual precocious puberty in younger patients. We present a case of a 7-month-old female infant found to have a sclerosing-type OSCST that presented with vaginal bleeding and very prominent vellus hair at the mons pubis. This represents the youngest patient reported in the literature with this subset of OSCST.     

Steroid-refractory ulcerative colitis and associated primary sclerosing cholangitis treated with infliximab

Primary sclerosing cholangitis is an infrequent extraintestinal manifestation of ulcerative colitis.Damage to bile ducts is irreversible and medical therapies to prevent progression of the disease are usually ineffective.We describe a patient with long-standing ulcerative colitis,which was refractory to corticosteroid therapy who developed primary sclerosing cholangitis(biochemical stage Ⅱ/Ⅳ) in the course of his pancolitis.Treatment with infliximab(5 mg/kg as an induction dose followed by maintenance doses every two months) was indicated because of steroid-dependent disease associated to primary sclerosing cholangitis as well as sacroiliitis and uveitis and previous episode of severe azathioprinerelated hepatic toxicity.At present,after two years of follow-up,the patient is asymptomatic with normal liver tests and complete resumption of daily life activities.This case draws attention to the usefulness of antitumor necrosis factor-alpha therapy for the management of primary sclerosing cholangitis as extraintestinal manifestation of inflammatory bowel disease.     

多部位硬化性骨髓炎1例报告

硬化性骨髓炎（Garre＇s osteomylitis），属特发性骨皮质硬化和干性骨髓炎，此病少见且病因不明，国内外报道鲜见。国外报道多发源于下颌骨病炎，而多部位骨骼受累未见报道。我院骨科于2004年收治1例因腰骶疼痛8年余，经过抗风湿治疗症状无缓解的患者。住院后经过X线片、CT和同位素骨扫描检查发现患者的上、下颌骨、双侧锁骨、     

Concurrent collagenous colitis and multiple heal carcinoids

Summary A case of collagenous colitis in a patient with ileal carcinoid is described. Considerable fibrofatty thickening of the small bowel mesentery was present. The association of these findings appears to be unprecedented. Further observations are required to ascertain that collagenous colitis is one of the protean manifestations of carcinoid tumor.     

Retractile mesenteritis of the large bowel: Report of a case and review of the literature

We report herein the case of a 46-year-old woman found to have retractile mesenteritis of the rectosigmoid colon. A review of 52 cases of retractile mesenteritis of the large bowel collected from the literature is discussed following our case report. The average age of the patients was 54.5 years and the male:female ratio was 37:15. The majority of lesions (61.5%) were located in the rectosigmoid colon, with abdominal pain, an abdominal mass, constipation, and fever being the most common symptoms. The diagnosis was only able to be made at the time of laparotomy in 90.4% of the patients. The gross appearance at surgery was characterized by a thickened, shortened, and retractile mesentery, forming nodular masses involving the appendices epiploicae of the colon. Microscopically, fibrosis, inflammatory cell infiltrations, degeneration of the fatty tissue or fat necrosis, and aggregations of lipid-laden foamy cells were observed in most patients. The mass involving the colon was resected in 59.6% of the patients, but even external or bypass colostomy demonstrated favorable results.
