Calcaneal unicameral bone cysts often contain fluid, but rarely contain fluid-fluid levels. We present a case focusing on the CT findings of a large calcaneal bone cyst with a fluid-fluid level and a review of the literature.
We report the MRI findings of a large deep intermuscular lipoma in a 2-year-old child with a painless palpable shoulder mass, and its differentiation from liposarcoma and other soft-tissue masses. To our knowledge, the imaging features of deep lipomas in children have not been reported.

Retroperitoneal lymphatic malformations can cause significant displacement, pressure, or entrapment of adjacent organs raising suspicion of a malignant retroperitoneal tumor. They often mimic ascites but may rarely be a cause of ascites. Computed tomography (CT) imaging findings in an infant with a cystic retroperitoneal lymphatic malformation and massive chylous ascites are reported.

We report sonographic features of bladder malacoplakia (multiple polypoid solid masses) in a 16-year-old girl with Russell-Silver syndrome who presented with renal failure and urinary tract infection.
The purpose of this study was to evaluate the utility of computed tomography (CT) renal angiogram (CTRA) in the management of childhood hypertension. This is a retrospective study of 24 children with clinical suspicion of renovascular disease who underwent CTRA examinations. CTRA demonstrated surgically correctable etiology of hypertension in 38% of the patients [5 with renal artery stenosis (RAS) and 4 with renal pathology]. In 5 patients, CTRA findings of RAS were confirmed by catheter angiogram. CTRA missed RAS in 1 patient in whom catheter angiogram showed beaded narrowing of the renal artery. All 6 patients with RAS had resolution of hypertension immediately after angioplasty or surgery. One patient with diffuse renal artery stenosis had an ipsilateral multicystic dysplastic kidney. In this patient hypertension resolved spontaneously as the dysplastic kidney shrunk in size. Seven patients had a renal etiology for hypertension. In 3 of these patients hypertension resolved after nephrectomy. Malignant hypertension in the 4th patient with reflux nephropathy was controlled medically after she underwent bilateral ureteral reimplantation. The remaining 3 patients with renal etiology were managed medically. We found that the etiology was central for hypertension in 4 patients with brain abnormalities, obesity in 1 overweight patient, essential hypertension in 4 patients, and thoracic aorta coarctation in 1 patient. Our study showed that in all except 1 instance CTRA could diagnose a surgically correctable cause for hypertension. CTRA provided useful information for the management of pediatric hypertension in all our patients.
