[A case of pulmonary mesenchymal hamartoma in a 9-year-old child].
This case of mesenchymatous hamartoma in a nine-year-old boy, was an incidental finding on a chest X ray. CT and MRI suggested the diagnosis showing a large (9 x 11 x 14 cm) mass developed in the right lower lung with sharp margins, without any sign of pulmonary or mediastinal compression. This lesion contained fatty areas on both CT and MRI. It showed no calcification. It enhanced slightly after IV contrast. On T2 WI, it appeared lobulated with low signal intensity septa. Presence of fatty tissues and lobulated margins were suggestive of the diagnosis of mesenchymatous hamartoma. A 1.2 kg mass was surgically removed. The tumor was attached to the right lower lobe by a small pedicle. Pathological examination disclosed fatty and connective tissues. This rare observation shows a good correlation between CT, MR, surgery and pathological examination.
