Background Reversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized condition characterized by thunderclap headache with or without other neurological deficits and diffuse vasoconstriction of cerebral arteries. Altered cerebrovascular tone may produce hemorrhage or stroke. Methods A retrospective review of patients with RCVS at our institution (2000–2023) yielded one case of pseudoaneurysm secondary to RCVS. Results Diagnostic cerebral angiogram demonstrated diffuse multifocal segmental narrowing consistent with RCVS and a left M4 pseudoaneurysm in proximity to the cortical hemorrhage. The pseudoaneurysm was treated with branch vessel sacrifice using nBCA glue in a 1 : 3 ratio with ethiodized oil. After securing the source of hemorrhage, the patient received an intra-arterial infusion of Verapamil. Conclusion This unique presentation of pseudoaneurysm secondary to RCVS in this patient highlights the impact of hemodynamic alteration as a possible source of bleeding and demonstrates a potential management strategy. Endovascular management with nBCA glue embolization successfully treated this lesion.

Introduction. Juvenile nasopharyngeal angiofibroma are benign tumors, with locally aggressive behavior. Preoperative tumor embolization with polyvinyl alcohol particles can reduce intraoperative blood loss and facilitate surgical resection. Case outline. A 16-year-old male, was admitted to hospital due to profuse epistaxis and sense of nose fullness. MDCT examination showed a tumor mass in the right nasal cavity with extension to the right maxillary sinus and ethmoidal cells on the right, and in the left nasal cavity. It rested on the nasal septum, but without bone destruction. After application of contrast agent, described mass became intensely opacified. Preprocedural digital subtraction angiography of external and internal carotid arteries of both sides showed extensive pathological vascularization, which received main contribution from branches of maxillary artery on right and, to a lesser extent, on left side. Due to danger of penetration of a particle embolization agent of smaller diameter into orbital branches and possible retrograde migration into carotid artery, we decided to apply particle embolization agent of larger diameter (500-700 ??) than prescribed by modern standards. Tumor was completely surgically removed third day after embolization, and patient was discharged without any neurological deficit. Control contrast enhanced MDCT-s were performed at third and seventh month after surgery and showed no tumor residue or recurrence. Conclusion. The use of particles of larger diameter gave satisfactory results during operation - surgical excision of tumor, when dangerous anastomoses do not allow use of particles of smaller diameter and can be safely performed without significant neurological nor systemic complications.
