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 scans of the thorax showed multiple, tiny, randomly distributed, nodular densities of 3–10 mm in size and numerous miliary nodules 1–3 mm in both lung fields compatible with multifocal micronodular pneumocyte hyperplasia. They were more predominant in the lung periphery and the upper lobes. Few tiny simple cysts were also noted. Plain chest radiographs revealed bilateral diffuse fine nodular opacities (
figs 1 and 2).
