Post-mortem examination showed enlarged and heavy lungs, with variably sized blebs covering the entire pleural surface without evidence of rupture or chylothorax. The cut surface revealed a diffuse cystic transformation of the entire parenchyma. The blebs were 0.7 cm in average diameter, filled with bloody fluid (Image 01). No chylothorax was identified, but the retroperitoneal lymph nodes appeared enlarged, forming conglomerates measuring up to 10 cm. Among other findings: the liver showed sub-massive necrosis, the brain had no evidence of lesions associated with tuberous sclerosis.
