Primary subdural tumor mimicking subdural hematoma: illustrative case.

ABSTRACT:

Background

Rare pediatric subdural tumors can mimic subdural hematomas and can be caused by lymphoma, sarcoma, and cancer metastases.

Observations

A 3-year-old boy with a history of chronic subdural hematoma, who had undergone multiple surgeries, was transferred to the authors' hospital with recurrent vomiting and lethargy. CT revealed a partially organized bilateral mass with heterogeneous intensities. Although the lesion was primarily located in the subdural space, a portion appeared to invade the brain.

Immunohistochemical and genetic analyses were performed, and the patient was diagnosed wit
