Hemihypertrophy
Pronunciation: hem-ee-hi-PER-troh-fee
Asymmetric overgrowth affecting one half of the body, associated with increased risk of embryonal tumors.
Full Definition
Hemihypertrophy, also called hemihyperplasia, is a condition characterized by asymmetric overgrowth of one side of the body or specific body segments. This condition is associated with an increased risk of developing embryonal tumors, particularly Wilms tumor and hepatoblastoma. Imaging plays a crucial role in surveillance protocols, with regular abdominal ultrasound or MRI recommended to screen for tumor development. The degree of asymmetry can be subtle and requires careful measurement and documentation.
Usage
Usage note: Always note the surveillance implications and associated tumor risks.
