Renovascular hypertension associated with a pelvic kidney and multicystic dysplasia.

We report on a 9-year-old boy with severe hypertension due to a variant of fibromuscular dysplasia of the renal artery supplying a functioning pelvic kidney. The other kidney proved to be a nonfunctioning multicystic remnant and several other congenital abnormalities of the genitourinary tract were present. Corrective vascular surgery was followed by normalization of arterial pressure and significant reduction of plasma renin activity. This is the first case report of renovascular hypertension due to renal artery stenosis in a single functioning pelvic kidney.

Lymphography and percutaneous lymph node biopsy in clinically localized carcinoma of the prostate.

Accurate staging of prostatic carcinoma requires determination of the status of the regional draining lymph nodes. Pelvic lymphadenectomy is the definitive examination but has certain morbidity and even mortality. Lymphography is safe but may not be sufficiently accurate. A total of 41 patients with clinically localized disease and abnormal or suspicious lymphograms underwent percutaneous lymph node biopsy. Ten of 11 patients (91 per cent) with abnormal lymphograms and 14 of 30 (47 per cent) with suspicious lymphograms had positive cytology studies. Of the suspicious defects an unopacified void in a nodal chain most frequently was positive. Of 22 potentially curable patients with stages A and B1 disease 12 had metastatic disease.

Adrenal adenoma associated with renal cell carcinoma.

Four cases of nonfunctioning adrenal adenomas associated with renal cell carcinoma are reported. The adenomas were found incidentally during angiographic examination of the renal carcinoma, and originally were thought to be metastases to the adrenal gland. Reports in the pathologic literature indicate an increased incidence of adrenal adenomas in patients with renal cell carcinoma. Adrenal adenomas occur in 12%-15% of patients with renal cell carcinoma as compared to 2%-3% of the general population. Since a vascular metastasis to the adrenal gland and an adrenal adenoma may appear identical angiographically, awareness of this association is important to avoid overdiagnosis of metastatic disease.

Carcinoma of the prostate: lymph node aspiration for staging.

Percutaneous fine-needle aspiration biopsy of suspect nodes was used for histologic staging in 33 patients with clinically localized carcinoma of the prostate after an abnormal or suspicious lymphogram. A total of 66 nodes was biopsied, and positive cytology for metastatic carcinoma was obtained from 29 nodes in 20 patients indicating the presence of stage D disease. Thus, staging lymphadenectomy and radical treatment by radiation or surgery were avoided.

Displaced paraspinal line: role of CT and lymphography.

Demonstration of involvement of lower mediastinal paravertebral nodes in lymphomatous or metastatic disease may alter the mode of treatment or localization of fields for radiotherapy. Displacement of paraspinal lines in a posteroanterior chest radiograph may indicate such adenopathy. In 20 selected cases in which computed tomography and/or lymphography were performed, 13 of 16 lymphograms and 11 of 11 CT scans helped confirm a paraspinal mass, suggesting adenopathy. Paraspinal line displacement, CT criteria of adenopathy, and the greater sensitivity of CT in the paraspinal area are discussed.

Restoration of renal function after bilateral renal artery occlusion.

Five patients had anuric renal failure caused by occlusion of the main renal arteries. All had a background of controlled hypertension, but in three patients, hypertension accelerated in the months before anuria. Extensive atherosclerotic disease was clinically evident in the peripheral (3/5), coronary (4/5), and cerebral (1/5) vessels. Identifiable precipitating events preceded the development of anuria in four patients. Although the use of renal ultrasonogram and scintiscan was suggestive, angiography was essential to establish the diagnosis after a brief period of maintenance hemodialysis. Renal artery revascularization performed as long as 38 days after the onset of anuria resulted in restoration of kidney function.

CT for diagnosis and management of urinary extravasation.

In 15 patients with extravasation of urine computed tomography (CT) findings immediately after urography were studied. In 11 patients leakage of urine was a postoperative complication. The extent of urine collections was better demonstrated by CT than urography in seven cases. Two patients had recurrent or residual tumor that was shown only by CT. One patient had an unsuspected second site of extravasation localized by CT. Diagnostic information obtained from the CT scan may be useful in planning appropriate treatment.

Post-lymphangiography fine needle aspiration lymph node biopsy in staging carcinoma of the prostate: preliminary report.

Five cases of clinical stage B carcinoma of the prostate are reported. Bipedal lymphangiography showed unequivocal involvement of the pelvic nodes in 3 patients and was equivocal in the other 2. Percutaneous transabdominal fine needle aspiration biopsy of abnormal or suspicious iliac nodes was performed and a positive cytolocal diagnosis of metastasis was obtained in all 5 patients. Therefore, staging lymphadenectomy and an extensive radical operation were avoided. Percutaneous fine needle biopsy is a reliable, easy and safe technique that should be used in staging prostatic carcinoma whenever there is evidence of metastatic nodal involvement by lymphangiography.

Systemic venous blood return via the portal vein.

The patterns of collateral circulation which develop following obstruction of the inferior vena cava have been classically divided into three groups depending upon the level of obstruction, i.e., infrarenal, middle caval, and upper caval. The portal vein can play an active role at all three levels. Multiple potential routes to the portal vein are described and 6 cases are presented.

Tubular stasis and ectasia due to intrarenal obstruction.

Segmental tubular stasis and ectasia may be early signs of intrarenal obstruction. Case reports of 3 patients are presented. In arriving at a diagnosis, the possibility of significant underlying pathology such as calculi and neoplasm should be considered.

Ultrasonography of the brachiocephalic arteries.

Sixteen patients with various lesions involving the brachiocephalic arteries were studied ultrasonographically. The examination was very useful in diagnosing aneurysms of the peripheral arteries and in differentiating an aneurysm from other causes of palpable pulsatile masses, such as a tortuous artery and tumor beneath an artery. The ultrasound technique used for evaluation of these lesions is described.
