Computed tomographic staging of malignant gastric neoplasms.

Eight patients with proved gastric carcinoma and 3 with gastric lymphoma were studied preoperatively with computed tomography. CT accurately identified abnormal stomach wall thickening and intra-abdominal tumor extension. Mural thickening was seen on the CT scan when a moderately distended stomach had a wall more than 10 mm thick. CT was useful for assessing surgical resectability, evaluating tumor response to chemotherapy or radiotherapy, and detecting postoperative recurrence. Fourteen patients with an abnormal barium study suggesting gastric malignancy were also studied with CT, which correctly demonstrated a normal stomach or identified the reason for the abnormal barium study, such as an unusual placed spleen or a pancreatic carcinoma invading the stomach.

Computed tomography in diagnosis of pelvic lipomatosis.

Pelvic lipomatosis is a rare condition which may be associated with obstructive uropathy. The radiologic features may be stimulated by pelvic malignancy and, in the past, surgery has often had to be performed for confirmation of the diagnosis. A case is described in which computed tomography (CT) provided definite proof that the pelvic organ displacement was due to excessive fat. It is considered that CT may obviate the need for further workup or surgery in these patients unless exploration is required for the relief of ureteric obstruction.

Pre-operative angiographic assessment of portal venous hypertension.

Fifty-three patients with portal venous hypertension underwent angiographic evaluation of the portal venous system. Arteriography was found to provide adequate opacification of the portal system in 52 patients. Arterial portography is a safer method than splenoportography and provides informaiton not obtainable by the latter method. Thus, hepatic arteriography demonstrated 2 unsuspected hepatomas in the present series. Catheterization of the hepatic veins and measurement of the wedged hepatic venous pressure provide a reliable estimate of the total portal pressure and of the severity of the portal venous hypertension. Vena caval pressure measurements and inferior vena cavography are helpful in the diagnosis of surprahepatic causes of portal hypertension, such as constrictive pericarditis and inferior vena caval diaphragm, and are also useful in the diagnosis of vena caval hypertension due to caudate lobe enlargement. Combined arteriography and venous studies are recommended as the initial radiological approach in all patients with portal hypertension who are being considered for portal-systemic shunt surgery.

Non-occlusive ischaemic colitis in a South African black. A case report.

A rare case of non-occlusive ischaemic colitis in a South African Black is described. The appearance of the bowel at an initial operation, and the histopathological changes demonstrated in the resected specimen after a subsequent operation, provide evidence for this diagnosis. The clinical presentation and radiological features which were also compatible with the diagnosis are presented. While the initiating mechanism remains obscure, it is suggested that ischaemia of the colon wall is likely to have been responsible for the final histopathological picture in this case.

Diagnosis and management of lymphoceles after renal transplantation.

Eight lymphoceles were encountered in 232 renal transplant procedures. The patients presented with either a palpable pelvic mass, ipsilateral leg pain and edema, or deteriorating renal function. Two patients were asymptomatic. The diagnosis is readily established by a combination of intravenous urography, ultrasound, and aspiration although ultrasound is the most useful method for the diagnosis and follow-up of these lesions. A functioning arteriovenous shunt in the leg on the side of the transplant may predispose to lymphocele formation. Most lymphoceles may be managed conservatively initially. However, if surgery is required, open drainage and packing would appear to be the most reliable procedure.

Angiography after renal homotransplantation.

The role of angiography in the investigation of problems encountered among 181 patients who received renal transplants at the Johannesburg General Hospital is analysed. In all, 23 patients underwent arteriography or venography after transplantation for the investigation of problems such as renal dysfunction, hypertension and suspected renal vein or iliofemoral venous thrombosis.

Spontaneous renal hemorrhage.

This report of 9 cases of spontaneous renal hemorrhage illustrates the wide variety of responsible conditions that may be found in a small series and the tendency for some of these conditions to coexist. In particular, all 3 patients with a bleeding diathesis had an associated anatomic lesion, and it was concluded that this group of patients required aggressive radiologic investigation. Three main clinical presentations were identified: sudden severe flank pain, symptomless hypertension, and a palpable mass with few or no symptoms. The radiologic signs are reviewed with emphasis on a recently described sign of streaky retroperitoneal fat. Treatment is discussed briefly.

Dance in physical rehabilitation.

Dance shows promise as an efficient, effective, and exhilarating physical therapy modality, with inherent sources of motivation for long-term neurological and orthopedic patients in a hospital or community setting. Four years' experience in adapting dance to the purpose of therapy in a group setting is described. The dance program developed combines the theories and techniques of physical therapy with the expressive, creative, and intellectual challenge of dance using music and other artistic motivating stimuli. Several dimensions of the modality are discussed and positive results are noted, through concrete illustrations.

The angiographic evaluation of renal pelvic carcinoma.

The angiographic findings are described in 6 cases of renal pelvic carcinoma. An angiographic finding which has not hitherto been emphasised is a diminished branching of arteries in the kidney segment related to the pelvi-calyceal tumour--the "pruned-tree" appearance. This is generally associated with a deficiency of the nephrogram in the same segment. These appearances may be due to invasion of the renal parenchyma by tumour. However, the findings may occur also in the absence of parenchymal invasion by the tumour and therefore do not necessarily reflect the stage of the disease.
