ABSTRACT We present a patient with sarcoidosis with an isolated intraparenchymal mass lesion that was similar to a glioma on magnetic resonance imaging. On fluid‐attenuated inversion recovery images, a small hyperintense signal change in the right uncus was observed. Three months later, enlargement of the abnormal signal lesion was observed. An initial diagnosis of glioma was made. A biopsy of the temporal lobe tumor was done. On histology, a noncaseating granulomatous inflammation consistent with neurosarcoidosis was diagnosed. Albeit rarely, we should consider the possibility of neurosarcoidosis in the differential diagnosis of isolated intraparenchymal mass lesion, when the mass is located beside the pia mater.
