Abstract EN

The obturator nerve is an extremely rare location for schwannomas to originate, and such diagnosis is typically not considered among the imaging diagnostic possibilities for a cystic-solid pelvic mass.

A 63-year-old female with a known pelvic mass presented with increasing pelvic pain.

The mass, which had been followed by serial imaging over five years, was described showing mixed solid and cystic components, likely arising from the left ovary.

Although the key diagnosis to be excluded was a primary ovarian malignancy, the patient chose to pursue active surveillance.

Over the five years of close observation, the lesion increased slowly, while her CA-125 level showed no significant elevation.

Increase in size of the mass and worsening pain and concern for a gynecologic malignancy on MRI led her to ultimately consent to a hysterectomy with bilateral salpingooophorectomy.

During the surgery, the mass was noted to be contiguous with the left obturator nerve.

Pathologic evaluation revealed a schwannoma (WHO grade I).

The patient’s postsurgical course was uneventful, without residual weakness in the left adductor muscles.
