Table 1 Published case reports of primary extracranial meningioma

Ref.	Year of publication	Site of primary extracranial meningioma	Diagnostic tests	Histology	Treatment performed
Maharjan et al[15]	2018	Nasal cavity	Contrast-enhanced CT of the nose and paranasal sinuses	WHO grade II atypical transitional meningioma	Endoscopic excision of the mass
Kim et al[18]	2018	Forehead	CT scan	Lobular architecture composed of tumor cells with eosinophilic cytoplasm and indistinct cell border	Excisional biopsy under local anesthesia
El-Daly et al[1]	1997	Maxillary antrum	CT scan	Interlacing bundles of bland-appearing spindle cells associated with calcific deposit	Medial maxillectomy with complete removal of the tumor
Ho et al[5]	1980	Right nasal cavity	Sinus x-ray and CT	Clearly demarcated meningioma with fibrous capsule and well-preserved pseudostratified respiratory epithelium	Ablation of the right frontal sinus, external ethmoidectomy and excision of the right middle turbinate
Nur et al[12]	2006	Right pelvic cavity	Pelvic sonogram	Lobulated pattern composed of solid sheets of tumor cells separated by connective tissue septae	Exploratory laparotomy with optimal debulking of the pelvic tumor
Albsoul et al[11]	2015	Right side neck mass	CT and MRI	Meningothelial cells with intranuclear inclusion and multiple psammoma bodies	Partial excision of the mass
Takeshima et al[9]	2004	Right ovary	Abdominal CT	Mature cerebral tissue was also noted. Melanocytes with black pigment were scattered in the peripheral region of the brain tissue	Right salpingo-oophorectomy
Lingen et al[8]	1995	Right maxillary sinus	CT	Bundles of ovoid and spindle-shaped cells arranged in broad bands	Total maxillectomy
Rege et al[16]	2017	Right retromolar area	CBCT	Spindle cell neoplasm, without evidence of atypia, whorls suggesting meningothelial origin	Partial resection of the mandible and reconstruction with autogenous iliac tricortical bone
Lee et al[17]	2017	Left eyebrow	CT	Tumor cells arranged in sheets or whorls, with occasional psammomabodies	Surgical excision
This Study	(Present case)	Maxillary sinus	CT and MRI	Epithelioid lobulated tissue, separated by abundant collagen fibers	Total maxillectomy with excision of tumor
