Congenital multifocal inflammatory pseudotumor: a case report.

ABSTRACT

Inflammatory pseudotumor is an uncommon benign tumor found in various sites throughout the body. The etiology is unclear with evidence to support both neoplastic and infective processes. The authors present a case with several unique features. It represents the first reported case detected antenatally. The tumor was found separately within the abdomen and thorax. The thoracic component of the tumor was managed without resection or ablative treatment but showed spontaneous regression.
