A primary pulmonary meningioma is a very rare form of ectopic meningioma.
They are generally asymptomatic and incidentally discovered although rarely patients with symptoms have also been reported.
Histologically, they comprise whorls of spindle cells interspersed with abundant psammoma bodies and are typically positive for vimentin, and EMA (epithelial membrane antigen).
CT
They are typically seen as solitary pulmonary nodule and may show homogeneous 6 or heterogeneous 3 enhancement.
Treatment and prognosis
These lesions are largely benign, but malignant lesions have been rarely reported 1. Many publications suggest resection in appropriate cases 7.
History and etymology
The first case was thought to have been described by Erlandson in 1981 7 while the first report in the English literature was thought to be by Kemnitz and Heinrich in 1982.
