Invasive fungal sinusitis is common in immunodeficiency patients and can spread into the orbit or intracranial cavity. The Onodi cell, which is one of the anatomical variations of the ethmoid sinus, refers to the space that has been pneumatized superolateral to the sphenoid sinus. We experienced a case of invasive fungal sinusitis that caused vision loss by invading the Onodi cells. Endoscopic sinus surgery and antifungal treatment successfully recovered the patient's vision and we herein report on the case with a review of the literature.
Epiphora is a symptom in which tears overflow onto the face, with its most common cause being the obstruction of the nasolacrimal system. As a cause of nasolacrimal system obstruction, nasolacrimal duct tumors are very rare. Angioleiomyoma, which is a benign tumor, arises from vascular smooth muscle, occurs in the nasolacrimal duct, and is extremely rare. With the development of endoscopic intranasal approach for the treatment of nasolacrimal duct obstruction, there is increased importance for the consideration of otorhinolaryngological evaluation and treatment as well as dacryocystorhinostomy by conventional external approach. In this article, we introduce a case in which angioleiomyoma in the nasolacrimal duct was detected by nasal endoscopy and was successfully treated with endoscopic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
