Tuberous sclerosis (TS) is an autosomal dominant disorder that is characterized by cutaneous lesions, seizures, mental retardation and hamartomas in various organs including the skin, kidney and brain. Pulmonary involvement is extremely rare, and occurs in approximately 0.1 to 1% of TS cases. Recent reports have indicated multiple micronodular pneumocyte hyperplasia (MMPH) as another rare form of pulmonary involvement of tuberous sclerosis. We report a case of a 35 year-old-male patient who had no pulmonary symptoms but showed multinodular pulmonary shadows on his chest CT scan. The patient was finally diagnosed with TS with MMPH of the lung. MMPH does not appear to have any malignant potential but the clinical significance of MMPH in TS patients is unknown.
