[Calcified brain metastases of a pulmonary neuroendocine carcinoma].
We describe an unusual case of pulmonary neuroendocrine carcinoma of intermediate cell type, revealed by calcified metastatic nodules of the brain in a 49-year-old man. Histological examination of the brain lesions disclosed necrosis and calcification in the center with small and medium-sized carcinoma cells. Pathophysiological mechanisms of such calcifications in metastasis lesions are reviewed.
