CTICasesMultifocal Micronodular Pneumocyte Hyperplasia
Imaging findings
CT chest shows multiple, stable bilateral ground-glass nodules scattered randomly throughout both lungs, without associated cysts or findings of LAM.

Multifocal micronodular pneumocyte hyperplasia (MMPH) is a rare, benign pulmonary manifestation of tuberous sclerosis. It is characterized by multiple nodular proliferations of type II pneumocytes, presenting on CT as stable ground-glass nodules that can mimic atypical adenomatous hyperplasia.
