Ultrasound in acute renal transplant rejection.

Gray-scale ultrasound and biopsy were compared in 63 patients with suspected acute kidney allograft rejection. Sonographic findings of increased size and decreased echogenicity of renal pyramide, focal zones of sonolucency in renal cortex, and patchy sonolucent areas involving both cortex and medulla with coalescence correlated well with biopsy in 46 out of 50 patients (92%) treated for acute rejection (sensitivity = 0.92). Abnormal perirenal fluid collection was encountered in three out of 60 patients (5%). Out of 63 sonographic studies, 10 (16%) gave either false positive (6) or false negative (4) results for an overall accuracy of 85%.

Abdominal staging of testicular tumors using ultrasonography and computed tomography.

There were 36 patients with testicular tumors who underwent abdominal staging by ultrasonography, computed tomography or both before removal and pathologic examination of the retroperitoneal lymph nodes. Results showed that ultrasonography and computed tomography are accurate in predicting retroperitoneal metastases in more than 80 per cent of the patients, although computed tomography is more accurate and specific. The 1 falsely negative result with both methods occurred in a patient with microscopic (pathologic stage IIA) retroperitoneal disease. The falsely positive results with either technique were found in patients with borderline enlargement of the nodes (1 to 1.5 cm). Either computed abdominal tomography or abdominal ultrasonography is recommended for pre-treatment staging of testicular tumors.

The angiographic appearance of intrarenal leiomyoma.

Two benign leiomyomas are described together with their radiographic and sonographic appearance, and the literature is reviewed. In large, asymptomatic renal masses, which are well circumscribed on angiography, a benign intrarenal leiomyoma may be considered. Nonechogenicity and relatively good through-transmission seem to substantiate the diagnosis.

Computer tomography, radionuclide imaging and ultrasonography in hepatic mass lesions.

The livers of 86 patients comprising this report were examined by both transmission computerized tomography (CT) and radionuclide scans (LS). Fifty-nine of them were also examined by gray-scale ultrasound (US). In a comparative study, the strengths and weaknesses of each modality were evaluated. CT demonstrated 85%. US 82%, and LS 73% of masses involving the liver. Because of better resolution and sectioning capabilities, together with stop-motion imaging, CT and US detected smaller and deeper mass lesions than did LS. However, LS was more informative in hepatocellular disorders than was US or CT. Our experience indicated that information obtained on the liver and surrounding structures by each imaging modality used here tends to be somewhat unique, and thus these procedures complement one another rather than being competitive.

Significance of pneumatosis cystoides intestinalis after jejunoileal bypass.

In 148 radiographs taken two weeks to twenty-seven months postoperatively in a series of 402 jejunoileal bypass patients at the University of Minnesota, twenty-four patients demonstrated roentgen evidence for pneumatosis intestinalis on twenty-eight separate episodes. This primarily involved the right colon. Clinical signs and symptoms were reviewed in association with the roentgen findings. Symptoms of nausea, vomiting, fever, and abdominal stress were noted but were not universal. Six patients had no significant change in abdominal complaints at the time the pneumatosis was seen and seven patients had similar clinical findings without roentgen evidence for pneumatosis. Thus, the radiographic findings of pneumatosis intestinalis do not represent a specific sign for bypass enteritis.
