Congenital asymmetry (hemihypertrophy) and abdominal disease: radiological features in 9 cases

Coexistent abdominal disease was found in 9 cases of congenital asymmetry. These patients appear to be at risk of malignant neoplasms of the adrenal gland, kidney, and liver. Five of the 6 neoplasms in this group of patients were malignant. Approximately 25% of the reported cases of hemihypertrophy have been associated with hamartomas or congenital defects, especially genitourinary anomalies. Benign disorders encountered in this group included medullary sponge kidney, renal ectopia, renal cyst, nephromegaly, adrenomegaly, and hypospadius.
