CLINICAL AND PARACLINICAL CHARACTERISTICS AND HISTOPATHOLOGICAL CORRELATION OF SINONASA HEMANGIOMAS
Main Article Content
Abstract
Objective: To describe the clinical and computed tomography features of sinonasal hemangiomas and correlate them with histopathological subtypes. Methods: A retrospective descriptive case series of 62 patients treated at the National Hospital of Otorhinolaryngology from January 2023 to March 2026. Results: Mean age was 43.4 ± 19.0 years; male/female = 1.3/1; capillary/cavernous hemangioma = 1/1. Epistaxis occurred in 61.3% and nasal obstruction in 51.6%. Endoscopically, tumors were pink (61.3%), smooth-surfaced (74.2%) and bled easily (58.1%). On CT, 88.7% enhanced after contrast, 16.1% showed bone erosion, and median size was 21.5 mm (9–37.5). Attachment sites were the paranasal sinuses (35.4%), turbinates (32.3%) and septum (16.1%). The two subtypes did not differ in age, sex, symptoms or surface morphology (p>0.05), but differed significantly in color (p<0.01), attachment site (p<0.001), bone erosion and tumor size (p<0.05). Conclusions: Sinonasal hemangiomas occur mainly in middle-aged adults, presenting with epistaxis and nasal obstruction. Capillary hemangiomas arise mainly within the nasal cavity, whereas cavernous hemangiomas arise from the sinuses and are larger with more bone erosion.
