A rare case of partially thrombosed giant serpentine right middle cerebral artery aneurysm presented. A 26 year old man initially presented with headache and 3 months later developed neurological deficit. Various stages of clot with patent residual lumen seen on neuroimaging, led to the diagnosis. Catheter angiography is the investigation of choice for evaluating the location, flow dynamics and extent of the serpentine aneurysm. The patient had embolisation done for the giant serpentine aneurysm.
Pulmonary arteriovenous malformations are rare vascular anomalies. We report a 12-year-old girl who presented with exertional dyspnoea, cyanosis and clubbing since the age of five years, and multiple pulmonary arteriovenous malformations. Computed tomography pulmonary angiogram showed a large pulmonary arteriovenous malformation at the lower lobe of the right lung. Pulmonary angiogram showed a large right lung arteriovenous malformation and two small left lung arteriovenous malformations. The multiple arteriovenous malformations were occluded with Gianturco coils. She is now asymptomatic and on regular follow-up.
Epistaxis is commonly encountered in otorhinolaryngologic practice. However, severe and recurrent epistaxis is rarely seen, especially that originating from a pseudoaneurysm of the intracavernous internal carotid artery (ICA). We herein present the case of a 32-year-old man who was involved in a motor vehicle accident and subsequently developed recurrent episodes of profuse epistaxis for the next three months, which required blood transfusion and nasal packing to control the bleeding. Computed tomography angiography revealed a large intracavernous ICA pseudoaneurysm measuring 1.7 cm × 1.2 cm × 1.0 cm. The patient underwent emergent four-vessel angiography and coil embolisation and was discharged one week later without any episode of bleeding. He remained asymptomatic after three-month and one‑year intervals. This case report highlights a large intracavernous ICA pseudoaneurysm as a rare cause of epistaxis, which requires a high index of suspicion in the right clinical setting and emergent endovascular treatment to prevent mortality.
