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

Medicine (Baltimore). 2017 Nov;96(47):e8684. doi: 10.1097/MD.0000000000008684.

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.
