The CT thorax revealed that, in addition to the now resolving hydropneumothorax with the intercostal drain in-situ, the lung parenchyma was riddled with multiple randomly distributed thin-walled round cysts of various sizes, but predominantly small (<2cm). The intervening lung was predominantly normal. A few fibrotic bands and resolving consolidation as evidence of prior infection were also seen. The findings were highly suggestive of pulmonary lymphangioleiomyomatosisin this clinical context (FIG 3). MRI brain revealed multiple cortical tubers and subependymal signal-intense white matter nodules strongly suggestive of tuberus sclerosis
