Case Reports Comparative Study
MR imaging of multiple sclerosis simulating brain tumor.
Multiple sclerosis may sometimes present as a mass lesion that is indistinguishable from brain tumor both clinically and radiologically. We describe two cases of multiple sclerosis simulating brain tumor on computed tomography (CT) scans and magnetic resonance (MR) images, one of which was proved and another was suggestive to be demyelinating disease by biopsy. Steroid therapy produced regression of the lesions of MR images and CT scans. Our cases and others in the literature suggest strategies for detecting multiple sclerosis presenting as a mass lesion.

Case Reports
Acquired intralobar bronchopulmonary sequestration secondary to occluding endobronchial carcinoid tumor.
We present the imaging findings of a 29-year-old man with an intralobar sequestration of the posterior segment of the left lower lung lobe, occurring distal to and sharing parasitized blood supply with a proximal occluding endobronchial carcinoid tumor. The etiology and pathogenesis of intralobar bronchopulmonary sequestration are discussed.
