Primary extraskeletal myxoid chondrosarcoma in cerebellum: A case report with literature review

Abstract

Rationale: Extraskeletal myxoid chondrosarcoma (EMC) is a rare malignant neoplasm of which intracranial EMC is the rarest. Patient concerns: We present an unusual case report of a 41-year-old woman who was sent to the emergency department for a sudden headache and other symptoms related to increased intracranial pressure. Interventions: Emergent CT revealed an occupying lesion in the left cerebellum with surrounding edema. A complete surgical excision of the lesion through a transcortical approach was performed. After the operation, this patient received adjuvant radiotherapy and temozolomide treatment. Diagnoses: Pathology diagnosis was an intracranial EMC. Outcomes: The patient survives with no tumor recurrence as of the last follow-up. Progression-free survival exceeded 20 months. Lessons: We have reviewed the literature and here summarize the diagnosis and treatment options for intracranial EMC. Diagnosis and treatment options of this rare disease are discussed.
