A rare intracranial leiomyoma, a benign smooth muscle tumor, was incidentally discovered during an autopsy. This extremely uncommon extra-uterine tumor highlights the diverse locations these neoplasms can manifest.

Area of Science:

Neuropathology
Oncology

Background:

Leiomyomas are typically benign tumors originating from smooth muscle cells, most commonly found in the uterine myometrium.
Extra-uterine leiomyomas are infrequent, making their occurrence outside the uterus noteworthy.

Observation:

This report details an incidental autopsy finding of a primary intracranial leiomyoma.
The tumor was discovered in a 60-year-old female patient who had passed away from acute myocardial infarction.

Findings:

The identified tumor was a leiomyoma located within the cranial cavity.
This represents an extremely rare instance of an extra-uterine leiomyoma in an intracranial location.

Implications:

This case underscores the potential for leiomyomas to occur in rare, extra-uterine sites, including the brain.

Keywords:

Dural-based extra-uterine intracranial leiomyoma
