Pediatric case of the day. Aneurysmal bone cyst.

Abstract: A 1 3-year-old boy had pain and swelling in his left knee. The frontal and lateral radiographs of the left knee show a lytic lesion in the proximal tibial metaphysis (Figs. 1A and 1 B). Sonography shows multiple fluid-fluid interfaces (Fig. 1C). MR images show the lesion to be of heterogeneous signal intensity, expanding, obliterating, and extending anterior to the cortex of the tibia (Fig. 1 D). The T2-weighted images show high signal intensity within the lesion; the multiple fluid-fluid fluid levels previous… Show more

A six-year-old girl presented with hypertension and headaches. IVP demonstrated a subtle calcification medial to the left kidney and a non-functioning lower pole raising concern for tumor. Color Doppler ultrasound demonstrated normal flow to the upper pole of the left kidney and a severely attenuated avascular lower pole, which was confirmed with selective angiography. Pathology of the surgically resected left kidney showed a calcified large renal artery aneurysm containing thrombus associated with fibromuscular dysplasia. Unique findings in this case were the presence of wall calcification and intraluminal clot in the aneurysm which resulted in nonvisualization of the aneurysm and absent flow to the lower pole.

Fibromuscular dysplasia of the renal artery: Management and outcome

Renovascular hypertension may be caused by atherosclerotic disease or less commonly by fibromuscular dysplasia (FMD) of the renal arteries. Fibromuscular dysplasia is the commonest cause of renal artery stenosis in the younger age group and affects women predominantly. A review of our clinical database identified all patients with renovascular hypertension. All relevant clinical, biochemical and radiological findings on those with FMD were noted. The outcome of percutaneous transluminal renal angioplasty (PTRA) or reconstructive surgery was evaluated. Eight out of 62 (13%) patients with hypertension secondary to renovascular disease had FMD (all female; bilateral in four; mean age at diagnosis 37.6 years; age range 12-70 years). The mean duration of hypertension before the diagnosis of FMD was 3.3 years (range 3 months-10 years). A renal artery bruit was detected in five, hypertensive retinopathy in three and one had mild renal insufficiency. Twelve PTRAs were attempted on 10 stenotic lesions in six women. This cured the hypertension in three, while the other three have required less antihypertensive therapy. Percutaneous transluminal renal angioplasty was complicated by a trivial renal artery dissection in one, and a small upper pole infarction in another. One patient required a repeat PTRA. The other two women presented before the availability of PTRA and had successful reconstructive surgery. Fibromuscular dysplasia was the cause of hypertension in eight out of 62 ( 13%) patients with renovascular hypertension. Percutaneous transluminal renal angioplasty has shown encouraging results with a low complication rate. If technically feasible, PTRA should be attempted on all patients with FMD of the renal artery.
