Intracranial presentation of systemic Hodgkin's disease.

Intracranial involvement by Hodgkin's disease is rare. We report a patient with Hodgkin's disease who had intracranial disease at presentation. We also review the literature pertaining to intracranial Hodgkin's disease. Using the key words "Hodgkin's disease" and "central nervous system (CNS) disease", we searched the Pubmed and Cancerlit databases. References were systematically reviewed and data regarding the following variables was extracted: age, gender, signs and symptoms at presentation, histology of Hodgkin's disease, cerebrospinal fluid analysis, stage and treatment. Only 36 cases of intracranial Hodgkin's disease were identified in the literature. Intracranial Hodgkin's disease at presentation is even more uncommon with only 8 reported cases. Most cases of intracranial involvement by Hodgkin's disease occur at the time of relapse. The most common presenting feature of intracranial Hodgkin's disease is a cranial nerve palsy with brain parenchyma being the most common intracranial site of involvement. Mixed cellularity histology is the most frequent subtype of Hodgkin's disease among these patients and the median survival following intracranial presentation is 46 months. Treatment has varied extensively but includes whole brain radiation with or without combination chemotherapy. Our literature review suggests that the prognosis is not dismal with appropriate treatment.
