A Rare Case of a Balo's Concentric Sclerosis-Like Lesion in a Young Adult Woman.

Balo's concentric sclerosis (BCS) is a rare demyelinating disorder of the central nervous system (CNS). Distinguishing BCS from other demyelinating disorders such as multiple sclerosis (MS) or from neoplasms can be difficult clinically; however, MRI aids in the identification of the disease. We describe the case of a 37-year-old female presenting with sudden onset of neurologic symptoms associated with a solitary rounded white-matter lesion suggestive of BCS. This rare disorder can present with heterogenous symptoms, imaging findings, and response to treatment. Furthermore, more in-depth analysis of the presentations and treatment outcomes of BCS are necessary in order to create a more robust plan of care.
