ABSTRACT
Renal ultrasonography was compared with intravenous pyelography in order to establish the suitability and accuracy of the former investigation as a screening method for ureteric obstruction in patients with carcinoma of the uterine cervix. With a sensitivity of 96.30%, specificity of 96.75%, a positive predictive value of 87.64% and a negative predictive value of 99.09% calculated on a large sample of 420 kidneys, it is recommended that renal ultrasonography is the method of choice in screening for ureteric obstruction in patients with cervical cancer. At the very least it is a suitable and equivalent alternative to intravenous pyelography in such patients.

Traumatic meningoceles in the lumbosacral region are extremely uncommon. Water-soluble contrast myelography has proved to be ideal for the diagnosis.

A 50-year-old woman presented with a focal liver mass which mimicked the clinical and imaging (ultrasonographic and computed tomographic) characteristics of a pyogenic or amoebic abscess. Ultrasonographic-guided liver biopsy demonstrated features of a focal tuberculous abscess of the liver.

A case of an aorto-mesenteric fistula presenting with portal hypertension and cardiac failure is presented. Both the computed tomographic and angiographic features proved valuable in the diagnosis of this unusual condition.

A 24-year-old man presented with acute pancreatitis. Serial ultrasonographic examination showed the development of bright echoes within the pancreatic parenchyma compatible with gas formation. This was confirmed on subsequent computed tomography and at laparotomy. The value of serial ultrasonographic examinations in pancreatitis is emphasized.

A case of extensive hepatocellular carcinoma with a massive arterioportal fistula is presented. The hepatofugal flow resulted in marked retrograde filling of the splenic, superior, and inferior mesenteric veins. Computed tomography confirmed the suspected clinical diagnosis of hepatocellular carcinoma.

A total of 78 patients were subjected to computed tomography (CT) over a period of 18 months. CT proved extremely accurate in the diagnosis of intraabdominal abscesses and in estimating the extent of spread. The series included many examples of amoebic and hydatid abscesses with unusual presentations and appearances. The commonest appearance of abscesses on CT was a low-density mass with peripheral rims after the administration of intravenous contrast media, followed by gas-containing low-density lesions which were regarded as showing characteristic features of abscess formation. Pitfalls in the CT appearance of abdominal abscesses were many and correlation with the clinical presentation was essential for diagnosis. The greatest value of CT lay in the rapidity of diagnosis.

Acute pancreatitis may present with a wide variety of clinical findings and may mimic other medical or surgical conditions. Three patients with acute pancreatitis are presented with clinical features of intestinal obstruction, perinephric abscess, and severe abdominal pain, respectively. The diagnosis and mode of spread of the inflammatory process in these patients was made by computed tomography. The value of computed tomography in the diagnosis of unusual extrapancreatic manifestations of acute pancreatitis is emphasized.

The computed tomographic (CT) findings of malakoplakia of the bladder are presented. Although the CT findings were not considered specific for this condition, the presence of a solid bladder mass with or without extension beyond the confines of the bladder in a young woman with urinary tract infection should suggest the possibility of this diagnosis.

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.
