Objectives: To evaluate success, complications and efficacy for endovascular management for carotid blowout syndrome.
Methods: Images were evaluated for contrast extravasation, vessel wall irregularity, pseudoaneurysm/aneurysm formation. Hemostatic results in the immediate postprocedural period and procedure related infarcts were assessed.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

The olfactory neuroblastoma is a rare malignant neoplasm derived from the olfactory neuroepithelium. It can metastasize to cervical lymph node chains and distant organs through hematogenous or lymphatic routes. Two clinical cases are presented: the first, a 56-year-old man with no pathological history, exhibited symptoms evolving over 2 months, characterized by persistent rhinorrhea with frequent epistaxis, ipsilateral proptosis, left hemicranial pain, anosmia, and dysgeusia.

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor originating from the olfactory neuroepithelium, typically within the sinonasal cavity. Cases of ONB originating outside of the olfactory cleft area are extremely rare and are referred to as "ectopic" (eONB), in contrast to "orthotopic" tumors (oONB). ONB has been associated with paraneoplastic syndromes (PNSs), including the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Olfactory neuroblastoma is an extremely rare malignancy of the sinonasal tract. It is a neuroectodermal tumor, originating from the olfactory epithelium of the nasal and sinus cavities. Due to its rarity, no standard of care treatments have been established to date.
