Abstract

Multifocal micronodular pneumocyte hyperplasia (MMPH) is a relatively rare pulmonary disorder that can be associated with tuberous sclerosis complex (TSC). It has been rarely reported in children or adolescents. MMPH is a hamartomatous process of the lung with multiple small nodules, composed of type II pneumocytes. Plain radiography and chest CT in MMPH may demonstrate numerous small nodules measuring 1?10 mm in diameters, distributed randomly throughout both lungs. If MMPH is an initial presentation of TSC, and unless we are familiar with this lung manifestation of TSC, radiologic findings can mimic miliary tuberculosis or metastatic disease. We report a teenage girl with TSC and histologically confirmed MMPH which mimicked miliary tuberculosis at the initial presentation.
