Primary pulmonary meningioma presenting with hemoptysis on exertion.
An 18-year-old woman presented with hemoptysis during long-distant running. A chest computed tomographic scan revealed a well-demarcated, round-shaped, solitary mass (3.0 cm in diameter) in the left pulmonary hilum. The bleeding was getting more often and a left upper lobectomy was carried out to avoid critical airway bleeding. A solid proliferation of short spindle cells with a remarkable whorl pattern was demonstrated histologically. Immunohistochemical studies showed positive for vimentin and S-100, and focally positive for epithelial membrane antigen. Primary pulmonary meningioma was thus diagnosed. The patient is well without recurrent disease 15 months after surgery.
