Medulla oblongata tuberculoma mimicking metastasis presenting with stroke-like symptoms

Abstract

Tuberculomas are common forms of central nervous system tuberculosis, presenting as space-occupying-lesions. Brainstem tuberculomas are rare among all intracranial tuberculomas. In old patients, in the absence of tuberculosis history, diagnosis may be challenging. In this case, we present a 70-year-old patient, with bladder cancer, without known tuberculosis who presented with stroke-like symptoms, clinically. Diffusion-weighted imaging revealed no finding of stroke, however, a medulla oblongata tuberculoma, mimicking metastasis was evident on MRI.
