A one-year and six-month-old female neutered Boxer dog was presented with a four-day history of pyrexia, lethargy and neck pain. An intracerebral haemorrhage and a mediastinal mass were identified. Cerebrospinal fluid analysis revealed severe neutrophilic pleocytosis, and steroid-responsive meningitis arteritis (SRMA) was suspected.

SRMA is a systemic disease with potential involvement of multiple organs. Intracerebral haemorrhage can occur secondary to SRMA and can have a successful outcome
