“…11 Trigeminal schwannomas account for about 0.2% of all intra cranial tumors, and 0.8% and 8% of intracranial schwannomas. 3 In the present case, the tumour showed evidence of originating from the second division of the fifth cranial nerve near the foramen rotundum. They can originate from any section of the fifth cranial nerve, from the root to the distal extracranial branches, but the majority develops at the Gasserian ganglion, usually growing in the middle cranium.…”

It was concluded that the tumour primarily originated within infratemporal fossa.…”

Schwannoma is a benign nerve sheath tumour that originates from schwann cells of the peripheral nerve. In spite of constituting 25-40% of head and neck tumours its in-traoral presentation is rare which accounts for only 1%. The purpose of this case report is to highlight the rarity of this lesion, to emphasize the significance of an accurate diagnosis and to include tumours of nerve sheath origin in the differential diagnosis of facial asymmetry.

“…12 Trigeminal schwannoma can develop anywhere along the course of the nerve with the Gasserian ganglion being the most commonly involved site. 13 Exclusive extracranial trigeminal schwannomas confined to the infratemporal fossa are rarely seen, with symptoms presenting as trigeminal nerve dysfunction, paraesthesia, hyperesthesia, facial pain, and wastage of muscles of mastication. 13,14 Diagnosis of a head and neck lesion suspected of schwannoma may be initiated with US.…”

Extracranial schwannoma of the maxillary nerve misdiagnosed as trigeminal neuralgia in an elderly patient with schizophrenia – A diagnostic dilemma

The present paper discusses the diagnostic challenges we faced in a 60‐year‐old woman with a history of schizophrenia, presenting with left unilateral facial pain for the past three months. Based on the elaborate clinical examination and diagnostic nerve blocks, the patient was diagnosed with trigeminal neuralgia (TN) and non‐surgical therapy commenced. Further investigations with magnetic resonance imaging (MRI) and ultrasound‐guided fine needle aspiration cytology (FNAC) revealed the presence of an extracranial schwannoma involving a branch of the maxillary nerve. The patient was symptomatically relieved after surgical excision of the benign tumor under general anesthesia. Hence, we emphasize the need for special care and attention in psychiatric patients presenting with orofacial pain.

“…For both adult and pediatric multicompartmental lesions, surgical corridors may include combinations of presigmoid, frontotemporal, subtemporal/ transpetrosal, and two-stage middle and posterior fossa exposures, [2][3][4][5][6]11 with or without the addition of endonasal endoscopic 2,[12][13][14][15][16] or transfacial (transmaxillary/transmandibular) approaches to target significant infratemporal extension. 4,11,[17][18][19] Management of TS in pediatric patients presents additional challenges because of anatomical differences, the potential for impact on development, and the need to minimize blood loss. Balancing treatment goals, including curative complete resection and minimizing morbidity, should occur in the context of the longer relative life expectancy of a child compared to that of an adult patient.…”

BACKGROUND Trigeminal schwannoma (TS) is an uncommon and histologically benign intracranial lesion that can involve any segment of the fifth cranial nerve. Given its often impressive size at diagnosis and frequent involvement of critical neurovascular structures of the skull base, it represents a challenging entity to treat. Pediatric TS is particularly rare and presents unique challenges. Similarly, tumors with extension into multiple compartments (e.g., middle cranial fossa, posterior cranial fossa, extracranial spaces) are notoriously difficult to treat surgically. Combined or staged surgical approaches are typically required to address them, with radiosurgical treatment as an adjunct. OBSERVATIONS The authors presented the unusual case of a 9-year-old boy with a large, recurrent multicompartmental TS involving Meckel’s cave, the cerebellopontine angle, and the infratemporal fossa. Near-total resection was achieved using a frontotemporal-orbitozygomatic craniotomy with a combined interdural and extradural approach. LESSONS The case report adds to the current literature on multicompartmental TSs in children and their management. The authors also provided a simplified classification of TS that can be generalized to other skull base tumors. Given a lack of precedent, the authors intended to add to the discussion regarding surgical management of these rare and challenging skull base lesions.
