Ultrasonography of biliary tract dilatation without jaundice.
The significance of intrahepatic biliary distension in the nonjaundiced patient was studied. Biochemical profiles and endoscopic and surgical findings were evaluated. Biliary tract disease was proven in 11 of 12 patients, with nine of the 11 having concurrent pancreatic disease. Ultrasound proved a more sensitive indicator of partial biliary obstruction than the serum bilirubin levels. The biliary tract of nonjaundiced patients with ultrasonographic evidence of biliary distension should be evaluated by additional studies regardless of the biochemical profile.
CT of abdominal tuberculosis.
Intraabdominal tuberculosis (TB) presents with a wide variety of clinical and radiologic features. Besides the reported computed tomographic (CT) finding of high-density ascites in tuberculous peritonitis, this report describes additional CT features highly suggestive of abdominal tuberculosis in eight cases: (1)irregular soft-tissue densities in the omental area; (2) low-density masses surrounded by thick solid rims; (3) a disorganized appearance of soft-tissue densities, fluid, and bowel loops forming a disorganized appearance of soft-tissue densities, fluid, and bowel loops forming a poorly defined mass; (4) low-density lymph nodes with a multilocular appearance after intravenous contrast administration; and (5) possibly high-density ascites. The differential diagnosis of these features include lymphoma, various forms of peritonitis, peritoneal carcinomatosis, and peritoneal mesothelioma. It is important that the CT features of intraabdominal tuberculosis be recognized in order that laparotomy be avoided and less invasive procedures (e.g., laparoscopy, biopsy, or a trail of antituberculous therapy) be instituted.

Ileocecal tuberculosis: CT and radiologic evaluation.
The CT and radiologic findings in 11 patients (five with AIDS and six without AIDS) with ileocecal tuberculosis are described. On CT scans, five cases showed mild circumferential wall thickening of the terminal ileum and cecum, thickening of the ileocecal valve, and a few regional nodes. One case presented as nonspecific small-bowel obstruction. In five patients a more characteristic CT appearance was detected: preferential thickening of the ileocecal valve and medial wall of the cecum, exophytic extension engulfing the terminal ileum, and massive lymphadenopathy with low-density areas consistent with caseation necrosis. Patients with AIDS had a more severe form of involvement than those who did not have AIDS. Barium studies showed ileocecal changes consistent with an inflammatory process. In conjunction with barium enema, CT is helpful in the initial evaluation of ileocecal tuberculosis, showing the location and extent of intestinal and mesenteric involvement in most cases. Characteristic CT findings are seen when the inflammatory process is severe.

Sonography of inflammatory bowel disease: findings and value in differential diagnosis.
OBJECTIVE: Inflammatory bowel diseases produce segmental or diffuse mural thickening of the intestine that can be detected and evaluated by using sonography. The purpose of this study was to evaluate the sonographic findings and determine their diagnostic value in patients with inflammatory bowel diseases. MATERIALS AND METHODS: We reviewed sonograms of 81 patients with inflammatory bowel diseases. The findings were compared with those of barium study, colonoscopy, and surgery. Forty-five patients had tuberculous enterocolitis, 13 had ulcerative colitis, eight had Crohn's disease, five had ischemic colitis, two had Behçet's syndrome, and eight had unspecified colitis. Diagnosis was based on surgical and pathologic findings in 23; results of barium study and endoscopic biopsy in 20; and results of barium study, colonoscopic findings, and clinical findings in 38. RESULTS: Seventy-two patients (89%) had sonograms that showed segmental or diffuse mural thickening and a paucity of luminal content in the involved bowel. Involved areas were the ileocecal region in the cases of tuberculous enterocolitis and Behçet's syndrome, the left side of the colon in ulcerative colitis, and the colon and terminal part of the ileum in Crohn's disease. In ischemic colitis, the distribution of involved bowel was nonspecific. Sonographic findings correlated well with the findings of barium enema or colonoscopy in terms of the involved segments of the bowel. Mesenteric lymphadenitis, omental thickening, and ascites were frequently observed in cases of tuberculous enterocolitis. CONCLUSION: Sonographic evidence of mural thickening of the bowel with a paucity of luminal content may be helpful in the detection of inflammatory bowel diseases. However, the findings are nonspecific, and the differential diagnosis must be related to the specific segment of the bowel involved.

Toxic amebic colitis coexisting with intestinal tuberculosis.
A patient with a fulminant amebic colitis coexisting with intestinal tuberculosis had a sudden onset of crampy abdominal pain, mucoid diarrhea, anorexia, fever and vomiting with signs of positive peritoneal irritation. Fulminant amebic colitis occurring together with intestinal tuberculosis is an uncommon event and may present an interesting patho-etiological relationship. The diagnosis was proven by histopathologic examination of resected specimen. Subtotal colectomy including segmental resection of ileum, about 80 cm in length, followed by exteriorization of both ends, was performed in an emergency basis. Despite all measures, the patient died on the sixth postoperative day. The exact relationship of fulminant amebic colitis and intestinal tuberculosis is speculative but the possibility of a cause and effect relationship exists. Fulminant amebic colitis may readily be confused with other types of inflammatory bowel disease, such as idiopathic ulcerative colitis, Crohn's disease, perforated diverticulitis and appendicitis with perforation. This report draws attention to the resurgence of tuberculosis and amebiasis in Korea, and the need for the high degree of caution required to detect it.
Biliary tuberculosis causing cicatricial stenosis after oral anti-tuberculosis therapy.
A 36-year-old Philippine woman presented with dark urine and yellow sclera. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed dilatation of the intrahepatic bile ducts and also showed an irregular stricture of the common hepatic duct at the liver hilum. Histological examination of biopsies from the bile duct revealed epithelioid cell granulomas and caseous necrosis. Tubercle bacilli were then detected on polymerase chain reaction (PCR) testing of the bile, giving the diagnosis of biliary tuberculosis. Although microbiological cure was confirmed, the patient developed cicatricial stenosis of the hepatic duct. She underwent repeated treatments with endoscopic biliary drainage (EBD) tubes and percutaneous transhepatic biliary drainage (PTBD) tubes, and the stenosis was corrected after 6 years. We present a case of tuberculous biliary stricture, a condition that requires careful differentiation from the more common malignancies and needs long-term follow-up due to the risk of post-treatment cicatricial stenosis, although it is rare.
Gallbladder tuberculosis: false-positive PET diagnosis of gallbladder cancer.
Gallbladder tuberculosis (GT) is an extremely rare disease, and very few cases have been reported in the literature. The first case of GT was described in 1870 by Gaucher. A correct preoperative diagnosis of GT is unusual, and it is frequently confused with various gallbladder diseases. We present a new case of a patient who underwent surgery with the preoperative diagnosis of gallbladder cancer after a false positive positron emission tomography scan in the diagnostic work-up.
