Inferior Alveolar Nerve Canal Position: A Clinical and Radiographic Study

Malignant peripheral nerve sheath tumour (MPNST) is a rare mesenchymal tumour which usually presents high grade malignancy. We report an atypical case of intraosseous malignant peripheral nerve sheath tumour on mandible in a 36-year-old male. Patient presented with an incidentally discovered radiolucency on the left anterior mandible and did not complain of any symptoms. Panoramic radiograph and computed tomography showed enlargement of inferior alveolar nerve canal, thinning of the cortex and calcified foci within an expansile mass. Magnetic resonance images revealed heterogeneous hyperintense signal intensity with a well-defined margin on T2 weighted images, heterogeneous enhancement on contrast-enhanced T1 weighted images and intermediate signal intensity and inferior alveolar nerve canal enlargement on T1 weighted images. In spite of benign radiologic characteristics as mentioned above, histopathologic examination of biopsied specimen otherwise revealed a low-grade malignancy. Wide excision of mandible was performed and there has been no loco-regional recurrence or distant metastasis over 1 year following surgery. This case indicates that, even when imaging modalities clearly demonstrate benign nature of intraosseous neurogenic tumour, care must be taken to establish proper treatment plan for assumed malignancy with a definitive histopathological analysis.

Inferior Alveolar Nerve Canal

Lipomas are the most commonly occurring soft tissue tumors, being intraosseous involvement very rare, and the jaw is its most uncommon bone location. Thus intraosseous mandibular lipomas constitute a real diagnostic challenge due to the unspecic clinical and radiographic features, therefore, only 28 cases have been reported in the literature. Herein we report an extremely rare case of an intraosseous mandibular lipoma that initially developed in Inferior alveolar nerve canal, characterize with dental cone beam computed tomography, and conrmed with histopathologic analysis after surgery. To the best of our knowledge, our case is one of the rst cases of intraosseous mandibular lipomas involving the inferior alveolar nerve canal never been previously reported. Their rarity reinforces the need to document each and every case.
