“…Diagnostic investigation of suspected sinonasal tumours depends firstly on thorough endoscopic evaluation and secondly on imaging techniques including CT and MRI. The characteristic findings of these tumours on CT imaging include a soft tissue mass with enhancement following the administration of intravenous contrast, and gadolinium contrast in the case of MRI scanning 11 . The role of routine angiography in the management of glomangiopericytoma is not clearly defined.…”

“…LEC generally spreads locally and even though the local spread is common at the time of diagnosis, the prognosis is very good [12]. On imaging, LEC of the maxillary sinus appears as a diffuse opacity of soft-tissue density [13].…”

Lymphoepithelioma-like carcinoma or lymphoepithelial carcinoma (LEC) of the maxillary sinus is an extremely rare malignancy. It is a rare type of undifferentiated carcinoma, consisting of atypical epithelial cells surrounded by reactive lymphoplasmacytic infiltrate. The paper reports the case of a 76-year-old male patient, with complain of swelling on the hard palate and epistaxis. Biopsy from the hard palate mass showed features consistent with LEC, with contrast-enhanced computed tomography nasopharynx and neck showing soft-tissue lesion in the right maxillary sinus. The patient is currently under treatment with external beam radiotherapy.

“…Pre-operative examinations must include neuroradiological investigation to detect the vascular nature of the tumor and its extension. CT scans of the nose and paranasal sinuses can demonstrate bone involvement, and the intravenous mean of contrast infusion can show tumor enahancement, but it does not allow a clear distinction with inflammatory fluid [14]. Usually, MRI scan shows a solid isointense mass, with a strong enhancement after gadolinium on T1 weighted sequences.…”

Background: Hemangiopericytomas (HPC) are rare mesenchymal tumors, which arise from the degeneration of Zimmerman's pericytes. They develop in the head and neck soft tissues in about 25% of cases and, in more than 50% of cases they involve the sinonasal region, especially the sphenoid sinus and ethmoidal labyrinth. Methods:We report the case of a 71-year-old caucasian male, with a history of recurrent epistaxis followed by total nasal obstruction and anosmia. Radiographic and endoscopic examinations revealed a multilobed hypervascularized mass (49x 59x 49mm), occupying the nasal cavity and the paranasal sinuses. Pre-operative embolization, followed by intratumoral direct injections of cyanoacrylate glue, was carried out. A completely endoscopic resection was then performed.Results: Post-operative histopatological and immunoistochemical examinations confirmed a sinonasal HPC. Endoscopic and radiological 2-year follow-up did not show any tumor recurrence. Conclusion:Endoscopic intranasal excision under endoscopic guidance, with preceded by embolization and direct cyanoacrylate glue injections, is an effective treatment for sinonasal HPC.
