Investigation of impotence by internal pudendal angiography: experience with 73 cases.

Angiography of the ileopudendal vascular tree was performed for the evaluation of impotence in 73 patients. This technique proved useful in identifying those cases caused by vascular lesions in major arteries and small penile vessels. Organic diseases cause a much higher proportion of impotence than in generally suspected, with vascular occlusions causing the greatest number of cases. Nocturnal penile tumescence (NPT) studies are the best screening procedure in the author's view. In this series, NPT was followed by angiography, which provided the definitive diagnosis.

[Myelolipoma of the adrenal gland in whole-body computed tomography. Report on 2 histologically confirmed cases with clinic-radiological correlations].

Myelolipomas are rare non-functioning benign lesions. They occur almost exclusively in the adrenals and are usually small and asymptomatic. We report two cases of unusually large symptomatic myelolipomas of the adrenal which were examined by urography, ultrasound, angiography and computed tomography (CT). A review of the literature of 25 similar cases is presented with a discussion of the pathogenesis. Diagnostic features of an adrenal myelolipoma are (1) a non-functioning, (2) radiolucent, (3) solid and (4) avascular mass arising from the adrenal. With CT the preoperative diagnosis becomes possible by assessing the fat contents, tumor alignment and lack of invasiveness.

Dissecting aneurysm of the cerebral arteries. Case report.

A spontaneous dissecting aneurysm of the left middle cerebral artery with extension into its major branches is reported in a 23-year-old man. The characteristic pathological and angiographic findings are demonstrated, including the rarely documented progression of this lesion. The etiological factors, the early recognition by the neuroradiologist, and the possibility of immediate treatment are briefly discussed in this report.

The sonography of renal columnar hypertrophy.

An enlarged Column of Bertin is a frequent cause of renal pseudotumor. In a retrospective study of the ultrasound findings in 11 patients with columnar hypertrophy, we have attempted to establish objective sonographic criteria of this entity. Columnar hypertrophy appears as a renal mass with the following characteristics: (1) indents the renal sinus laterally; (2) clearly defined from the renal sinus; (3) largest dimension of less than 3 cm; (4) continuous or contiguous with the renal cortex; and (5) Echogenicity close to that of the cortex. Two minor criteria are also presented, and the present appropriate use of the criteria is suggested.

Computed tomographic diagnosis of pulmonary sequestration.

Two cases of pulmonary sequestration demonstrated by CT scans of the chest are described. In one, CT demonstrated the anomalous artery. This finding may obviate the need for angiography when surgery is not contemplated.

Abdominal plexiform neurofibromatosis simulating pseudomyxoma peritonei on computed tomography.

We present and discuss an unusual case of extensive abdominal plexiform neurofibromatosis that simulated pseudomyxoma peritonei on CT. Multiple low density subdiaphragmatic masses caused scalloped liver margins and thickening of the mantle, which displaced bowel loops centrally, suggesting the diagnosis of pseudomyxoma peritonei. However, open biopsy revealed plexiform neurofibromatosis.

CT of long-standing ankylosing spondylitis with cauda equina syndrome.

The authors present distinctive computed tomographic (CT) findings in two cases of long-standing ankylosing spondylitis accompanied by the cauda equina syndrome. Multiple, asymmetric erosions of the posterior elements of the lumbar spine on CT were correlated with thecal diverticula demonstrated by myelography. The pathogenesis of these erosions may be related to arachnoiditis in the early phase of the spondylitis.

Cranial computerized tomography in systemic lupus erythematosus.

Twelve patients with active central nervous system systemic lupus erythematosus (CNS SLE) and 11 patients without CNS involvement, all taking corticosteroids, were studied by computerized tomography (CT). Thirty CT scans on 23 individuals were performed and read blindly and independently by 2 neuroradiologists with an 86% correlation. Minimal to moderate atrophy was the most frequent finding, both in CNS SLE and controls, severe atrophy seen in 1 patient only, and no atrophy in 3 patients and a single control. Of the 6 patients who had repeated scans, 4 showed no change in the degree of atrophy, 1 had more and 1 less atrophy. Three patients had evidence of multiple brain infarcts on scan with or without associated cerebral atrophy. Sequential scans in 1 of these patients showed total resolution of the infarcts after 30 months. Thus, there was no correlation between the presence of cerebral atrophy on CT scan and CNS SLE. Rather our findings suggest that steroids may be the cause of atrophy.
