Schwannoma With Cystic Changes in the Pterygomandibular Space

This report is on a case of schwannoma with cystic changes that occurred in the pterygomandibular space. A 46-year-old woman presented with a complaint of limited mouth opening and pain on the left side of the mandible for 3 months. On panoramic radiography, radiolucency was seen on the left mandibular ramus. On enhanced computed tomography, a 4 × 3 cm cystic mass was found along the inner side of the left mandibular ramus area. Magnetic resonance imaging showed a multiseptated, well-demarcated cystic lesion on the inner side of the mandibular ramus on the left side. Under general anesthesia, the tumor was excised. The final diagnosis was schwannoma with cystic changes. Lower lip hypoesthesia occurred postoperatively. At the 1-year postoperative follow-up, maximum mouth opening was increased to 44 mm, and lip hypoesthesia was improved.
