Ultrasonography of discoid adrenals in Potter's syndrome: report of three cases.

Potter's syndrome, a rapidly fatal congenital disorder marked by renal agenesis, can be diagnosed in the first hours of life with real-time ultrasound. In infants with Potter's syndrome the adrenal glands assume a discoid shape and occupy the renal beds, thereby mimicking the absent kidneys. However, discoid adrenals can be distinguished from either normal or dysplastic kidneys by definitive ultrasound criteria. The ultrasound appearance of an echogenic medulla and a hypoechoic cortex in a posteriorly placed, flattened adrenal gland is quite different from the neonatal kidney with its echogenic cortex and hypoechoic renal pyramids. Early diagnosis is desirable to facilitate management of this hopeless condition. Difficulties with reliable antenatal ultrasonographic diagnosis of Potter's syndrome are discussed.

Childhood Menetrier's disease: four new cases and discussion of the literature.

Four cases of childhood Menetrier's disease are presented and their clinical and laboratory findings are compared with the other childhood cases reported in the literature. Children with Menetrier's disease usually present with abdominal pain or nausea and vomiting associated with peripheral edema, ascites, or pleural effusion; these symptoms are due to gastrointestinal protein loss and resultant hypoproteinemia. There is no evidence of urinary protein loss. The favorable clinical course as well as distinctive laboratory and roentgenologic findings distinguish this entity from other causes of these symptoms. Supportive therapy is normally all that is required since the symptoms resolve spontaneously in weeks to months. Surgery may be needed in rare cases of active gastrointestinal hemorrhage.

A new skeletal dysplasia: clinical, radiologic, and pathologic findings.

Two siblings, one male and one female, were noted to have a distinct skeletal dysplasia. The clinical and radiographic features resemble those observed in Kniest dysplasia and Rolland-Desbuquois syndrome, but important differences were noted. Specifically, these two patients have microstomia, "pursed" lips, and ectopia lentis, and their radiographs reveal no coronal clefts. Chondro-osseous features also differ from those observed in either of the other disorders. Scattered dense patches consisting of collagen fibers 10 to 30 times broader than normal are seen scattered throughout the cartilage matrix; the "Swiss cheese" appearance characteristic of Kniest dysplasia is not observed. These patients appear to have a new skeletal dysplasia, most likely inherited in an autosomal recessive fashion.

Preoperative diagnosis of unilateral multicystic kidney with hydropelvis.

We present 2 patients with congenital unialteral multicystic kidney disease with hydropelvis. In the first patient the diagnosis was made by precutaneous puncture of a renal cyst followed by injection of contrast medium; in the second the diagnosis was confirmed by percutaneous puncture of the renal pelvis and injection of contrast medium, although an earlier ultrasonic examination had been strongly suggestive. Since in this condition the cysts and the renal pelvis communicate, either can be punctured to make the diagnosis. The procedures herein described are definitive for the diagnosis and should be followed whenever the urologist desires such a diagnosis.
