Abstract

The aim of this study was to report a case of sinonasal meningioma in Sudan. Meningiomas account for nearly 20% of all intracranial neoplasms and are the second most common tumor of the central nervous system. Primary meningiomas of the nose and paranasal sinuses are extremely rare. The clinical and radiological features of these tumors are nonspecific, and consequently an accurate diagnosis requires histologic evaluation. A 62‑year‑old woman from North Sudan presented to our hospital in May of 2016 complaining of right nasal obstruction associated with bloody nasal secretion and proptosis. Endoscopic endonasal examination revealed a soft mass in the right nasal cavity between the septum and the middle and superior turbinates posteriorly. MRI revealed the presence of a lobulated mass with soft‑part density in the right nasal cavity (middle meatus) and the right ethmoid sinus invading the orbital contents and extending intracranially. The biopsy of the lesion revealed nodular neoplasm composed of regular cells arranged in whorled pattern. One psammoma body was noted and there was no evidence of pleomorphism or necrosis. The features are consistent with sinonasal meningioma. The patient was referred to the oncological department because it was an unresectable malignant meningioma and surgery was not feasible and would create more complications. Meningiomas involving the nasal cavity and paranasal sinuses are rare. The mortality is low, and its lethality is due to the complications of the surgery and injury of vital structures. Complete surgical extirpation of sinonasal tract meningiomas has an overall good prognosis. Hence, endoscopic nasal approach is an excellent surgical option in these cases, due to its low morbidity and satisfactory lesion resection.
