Ovarian microcysts in girls with isolated premature thelarche.

We compared the frequency of ovarian microcysts in girls with premature thelarche (n = 27) to that in age-matched control subjects (n = 24). There was an increased prevalence of detectable ovarian microcysts in girls with premature thelarche. The presence or absence of cysts did not correlate with basal gonadotropin or estradiol levels.

Parotid enlargement in children seropositive for human immunodeficiency virus: imaging findings.

We investigated the clinical, immunologic, and imaging features of parotid enlargement in 10 children seropositive for human immunodeficiency virus (HIV) who were infected prenatally. In seven patients, sonography revealed many small hypoechoic areas suggestive of lymphoid infiltration. In three older children, large anechoic areas suggesting lymphoepithelial cysts were present.

Midgut volvulus in infants: diagnosis with US. Work in progress.

The authors present findings from ultrasound (US) studies that can alert sonologists to the possibility of midgut malrotation complicated by volvulus in neonates and infants. A fluid-filled, distended duodenum seen at US examination in infants is a nonspecific sign of duodenal obstruction, as well as one of the signs of midgut malrotation. In addition, dilated, thick-walled bowel loops, mainly to the right of the spine, and peritoneal fluid were found at abdominal US examinations of three infants with midgut malrotation complicated by volvulus.

Sonographic abnormalities of the thyroid gland in longterm survivors of Hodgkin disease.

We studied the thyroid gland in 18 long term survivors of Hodgkin Disease, all of whom received radiation therapy (2400-4000 cGy, mean 3434). Evaluation included clinical examination, thyroid function tests, ultrasound, as well as selective use of nuclear scintigraphy. The time interval post radiation was 1-16 years (mean 6.

Magnetic resonance imaging in the diagnosis of adolescent colorectal carcinoma.

A 14-year-old girl presented with a large abdominal mass, thought to be an ovarian tumor on the basis of clinical and sonographic findings. MRI correctly suggested a primary colonic neoplasm. At operation, ovarian involvement was found to be secondary to metastatic signet ring cell adenocarcinoma of the colon, an extremely rare malignancy in this age group.
