Laparoscopic Extirpation of a Schwannoma in the Lateral Pelvic Space

View Article: PubMed Central - PubMed

ABSTRACT

Schwannomas in the lateral pelvic space are very rare. Here, we report the case of a 48-year-old woman who had a tumor detected in her abdomen by abdominal ultrasonography. Abdominal computed tomography and magnetic resonance imaging revealed a well-defined solid tumor of 65 mm in diameter in the right lateral pelvic space. We performed laparoscopic surgery under a diagnosis of a gastrointestinal tumor or neurogenic tumor. The tumor was safely dissected and freed from the surrounding tissues using sharp and blunt maneuvers. The tumor originated from the right sciatic nerve. Complete laparoscopic extirpation was performed with preservation of the right sciatic nerve. Pathological examination suggested schwannoma. The patient recovered well but had remaining sciatic nerve palsy in her right foot. Laparoscopic extirpation for a schwannoma in the lateral pelvic space was safe and feasible due to the magnified surgical field afforded by laparoscopy.

Mentions: A 48-year-old woman was admitted to our hospital with a mass in the pelvic space that was detected on abdominal ultrasonography (US). She had no past or family history of note. She had mild numbness in the right leg. Enhanced abdominal computed tomography (CT) revealed a 65 × 50 mm, solid, well-defined, heterogeneous mass in the right lateral pelvis space (Figure 1(a)). Magnetic resonance imaging of the tumor revealed heterogeneous hyperintensity on T2-weighted images (Figure 1(b)). The preoperative diagnosis was a gastrointestinal stromal tumor or a neurogenic tumor in the right lateral pelvic space. We performed laparoscopic extirpation of the tumor as follows.
