Figure 7.

Axial computed tomography image (A) of a middle aged man showing round hypodense lesion in left lower lobe with pleural effusion. Corresponding T2-W magnetic resonance images (MRI) in axial (A) and coronal plane showing hypointense wall (arrow in B) with intralesional hypointense membranes or septations (arrow in C) suggesting hydatid cyst. Axial T1-W MRI (D) shows isointense to muscle lesion. Post-contrast T1-W coronal image (E) shows enhancement of wall and internal septations. USG was done which revealed round lesion with both solid and cystic components (F). Patient was operated and biopsy showed cystic schwannoma
