Generalized lymphatic anomaly involving the pleura and bone in an older male: A case report

Generalized lymphatic anomaly (GLA) is a congenital malformation of the lymphatic vessels that is often diagnosed in early childhood. Owing to the rarity and heterogeneity of its clinical course, GLA is frequently misdiagnosed, especially in adults. A 67-year-old man was incidentally found to have bone and pleural lesions. Multiple bone lesions detected on magnetic resonance images were mistaken for malignancy, and pathological evaluation led to the diagnosis of GLA. GLA should be considered in the differential diagnosis of multiple bone lesions, and a proactive biopsy to confirm the diagnosis may help avoid unnecessary invasive procedures.
