This case report presents a rare diagnosis of primary leptomeningeal medulloblastoma in an adult, highlighting its unique metastatic pattern.
Medulloblastomas are tumors of the posterior fossa that have a propensity to develop leptomeningeal metastases along the spinal cord, commonly known as “drop metastases.” Medulloblastoma accounts for approximately 1%–2% of all adult brain tumors, and reports of primary leptomeningeal medulloblastoma are extremely limited. Herein, we present a rare case of a 34‐year‐old woman diagnosed with multifocal primary spinal leptomeningeal medulloblastoma without cranial involvement.
