Tuberous sclerosis diagnosed by incidental computed tomography findings of multifocal micronodular pneumocyte hyperplasia: a case report

چکیده
UNLABELLED INTRODUCTION The majority of multifocal micronodular pneumocyte hyperplasia associated with tuberous sclerosis complex is diagnosed with the classical clinical triad of seizures, mental retardation, and skin lesions. We report a rare case of tuberous sclerosis complex with no classical clinical findings, which was diagnosed through incidental computed tomography findings of multiple nodular lesions of multifocal micronodular pneumocyte hyperplasia. CASE PRESENTATION A chest computed tomography scan of a 51-year-old Japanese woman showed multiple nodular ground-glass opacities that were not seen on chest X-ray. Video-assisted thoracoscopic surgery was performed. A histological examination demonstrated type II pneumocyte hyperplasia with thickened fibrotic alveolar septa, which was consistent with multifocal micronodular pneumocyte hyperplasia. Brain magnetic resonance imaging displayed multiple cortical tubers, and abdominal computed tomography showed bilateral renal angiomyolipoma. Our patient was finally diagnosed as having tuberous sclerosis complex with multifocal micronodular pneumocyte hyperplasia, although she had no episodes of epilepsy, no skin lesions, and no family history. CONCLUSIONS Multifocal micronodular pneumocyte hyperplasia with latent tuberous sclerosis complex should be considered in the differential diagnosis of multiple ground-glass opacities.

UNLABELLED BACKGROUND The autosomal dominant tumor syndrome tuberous sclerosis complex is caused by the mutated TSC1 gene, hamartin, and the TSC2 gene, tuberin. Patients with this complex develop typical cutaneus symptoms such as peau chagrin or angiofibromas of the skin as well as other lesions such as astrocytomas in the brain and lymphangioleiomyomatosis in the lung. Only a few tuberous s...

A 29-year-old woman, a known case of tuberous sclerosis, presented to our hospital with a 1-day history of multiple episodes of convulsions. This was associated with vague chest and abdominal pain. CT scans of the brain showed multiple calcific foci in the gray-white matter junctions and in the periventricular region. CT of the abdomen revealed liver hamartomas and renal angiomyolipoma. CT scan...

A case of multifocal micronodular pneumocyte hyperplasia (MMPH) associated with tuberous sclerosis is reported. MMPH is a rare pulmonary disorder characterized by the nodular proliferation of type II pneumocytes. In the case presented here, MMPH appeared as multiple, well-defined small nodules with ground-glass opacity. It is necessary to consider MMPH when small nodules with ground-glass opaci...
