Cavernous Hemangioma of the Maxillary and Ethmoid Sinus Treated Endoscopically

Abstract

Hemangiomas are a benign vascular tumor and are of two types: capillary and cavernous. Isolated cavernous hemangiomas of paranasal sinuses are rare. We report a case of hemangioma involving the left maxillary and ethmoid sinus managed endoscopically.

A Rare Case of Sinonasal Cavernous Hemangioma

“…The distinction between the cavernous and the capillary types is not always well defined as the microscopic size of the predominant vessels can vary in different areas of the tumor [4]. The differential diagnosis of hemangioma includes inverted papilloma, pyogenic granuloma, mucocele, hematoma, polypoid cystic masses and bacillary angiomatosis, Kaposi’s sarcoma, and other vascular tumors of the paranasal sinuses, like angiosarcoma [6].…”

“…MRI demonstrates isointense lesion on T1-weighted sequences and hyperintense lesion on T2-weighted sequences, compatible with low-flow vascular structures [6]. Phleboliths show T I hypointensity and T2 hyperintensity on magnetic resonance imaging [1, 4].…”

“…Cavernous hemangioma of the maxillary sinus is rare [6]. It grows slowly and causes local destruction due to pressure effect.…”

“…The main clinical features are chronic rhinorrhea, nasal obstruction, facial pain, persistent epistaxis, and central facial deformity [6, 7]. Differential diagnoses of sinonasal cavernous hemangiomas include long-standing sinonasal polyps, mucoceles, inverted papillomas, polypoid cystic masses, angiosarcoma, other vascular lesions, neuroma, neuroblastoma, or lymphoma.…”

Diagnostic conundrum of periorbital vascular lesions: from the unexpected to the typical

“…Diplopia, visual field defects and gaze‐induced amaurosis may also occur . Cavernous venous malformations arising from sinonasal origins have been reported but are comparatively rare . However, the clinical entity of periorbital non‐distensible cavernous venous malformations is not well described.…”
