Skull base osteomas (SBOs) are benign tumors that are frequently detected on radiographic images by coincidence. They are known for being slow-growing tumors and rarely symptomatic. The therapeutic approach for SBOs can differ substantially. Depending on the symptoms, size, and location of the tumor, this can range from serial observation to vigorous surgical extirpation. Clival osteoma is extremely rare. We report a case of clival osteoma, causing intractable trigeminal neuralgia due to the pressure effect on the trigeminal nerve at Meckel's cave. We also provide a review of pertinent literature. A 37-year-old woman presented with intractable trigeminal neuralgia. Cranial magnetic resonance imaging (MRI) demonstrated a large, lobulated, extra-axial lesion involving the right cerebellopontine angle and epicentering the clivus. Pathologically, the specimen was proven to be osteoma. The patient reported complete symptom resolution over a 4-year follow-up period. To the best of the authors' knowledge, this is the first clinical case of intractable trigeminal neuralgia due to clival osteoma.

Background Osteomas are benign slow-growing tumors, which typically arise on the surface of the bone. They rarely arise from the temporal bone, accounting for 0.1–1% of all benign tumors of the skull. The external auditory canal (EAC) is the most common site for osteomas in the temporal bone. Other extra-canalicular osteomas of the temporal bone are uncommon and infrequently reported. In this case report, we discuss the clinical presentation and surgical management of osteoma of the squamous part of the temporal bone. A limited review of literature is also presented. Case presentation A 20-year-old male presented to the outpatient department (OPD) with a chief complaint of a hard swelling above his left ear, for 4 years. He had no other complaints other than cosmetic concern. On examination, there was a solitary, smooth, bony hard swelling just antero-superior to the left pinna, and the overlying skin was unremarkable. The left EAC and tympanic membrane were normal. A non-contrast computed tomography (CT) scan of the head and face with 3-D reconstruction showed a16 × 18 mm exophytic, pedunculated bony lesion arising from the squamous part of the temporal bone suggestive of an osteoma. The patient was taken up for surgical excision under general anesthesia. The bony lesion was removed from its attachment to the skull using a gouge and a mallet. The base of the tumor was drilled using a polishing burr to ensure complete removal and prevent recurrence. The histopathology was confirmatory of compact osteoma. Postoperative period was uneventful, and follow-up at 18-month post-surgery did not reveal any recurrence clinically. Conclusion Osteoma of the temporal squama is rarely reported, and surgical excision is the definitive treatment if symptomatic. This case report highlights the surgical management of this rare tumor. A limited review of literature suggests that squamous part of the temporal bone is an unusual site for extra-canalicular osteomas, and the prognosis is good after surgery.
