title: Tuberous sclerosis complex complicated by pulmonary multinodular shadows.
abstract: A 41-year-old woman with a history of epilepsy was referred for multiple nodular ground-glass opacities on a chest computed tomography (CT) scan. They were initially suspected of representing atypical adenomatous hyperplasia or well-differentiated adenocarcinoma. However, the subsequent brain CT and magnetic resonance imaging (MRI) scans revealed a coarse nodular calcification and cortical tubers. A subungual fibroma was also noted. Histological examination of a video-assisted thoracoscopic lung biopsy specimen disclosed multiple nodules of type II pneumocyte hyperplasia with septal thickening. Based on all of these findings taken together, a diagnosis of tuberous sclerosis complex with multifocal micronodular pneumocyte hyperplasia (MMPH) was made.
