Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a rare and poorly understood pathology. In this case report we present a 51-year-old male that presented with neurological deficits with recent hypersensitivity pneumonitis. Imaging studies showed multiple punctate enhancing lesions involving the brainstem. After initiation of corticosteroids his symptoms improved, with a decrease in size of his lesions 6-months after his initial presentation. Due to its misdiagnosis, we propose the use of diagnostic criteria, described on this case report, for prompt treatment to avoid neurological sequelae.
