The treatment of complicated anterior cerebral artery aneurysms remains challenging. Here, the authors describe a case of ruptured complicated A3 aneurysm, which was treated with trapping and in-situ bypass. A 47-year-old man presented to the emergency department with severe headache and vomiting. Computed tomography illustrated acute intracerebral hemorrhage in the right frontal lobe. Digital subtraction angiography (DSA) confirmed a ruptured fusiform A3 aneurysm with lobulation and a daughter sac. Trapping of the ruptured fusiform A3 aneurysm and distal end-toside A4 anastomosis was performed. DSA on postoperative day 7 showed mild vasospasm to the afferent artery. However, 2 months later, DSA demonstrated that the antegrade flow through the anastomosis site had recovered. Thus, surgeons should be aware of the possibility of postsurgical vasospasm of anastomosed arteries, especially in cases of ruptured aneurysms.

Arteriovenous malformations (AVMs) consist of multiple connections between arteries and veins without a capillary bed and are characterized by an early draining vein. This pathology affects mainly young adults, and the morbimortality is caused mostly by rupture and hemorrhage. In this Video 1, we present a case of a 29-year-old female patient presenting with a sudden severe headache.

Introduction: Ruptured vertebral artery dissections frequently exhibit pearl-and-string signs, a characteristic also observed in many unruptured dissections. This study examines the natural course of 50 unruptured acute vertebral artery dissections presenting with pearl-and-string signs and compares them to 10 ruptured dissections of the same morphological pattern.
Methods: We reviewed 633 radiology reports of head and neck imaging studies that included the keyword 'dissection'.
Ruptured aneurysms in peripheral arteries are rare, and an optimal treatment strategy has not yet been established. Herein, we evaluated the efficacy and safety of endovascular treatment of peripheral aneurysms located in small, tortuous vessels. In the present study, we report five consecutive cases of small, peripherally located ruptured aneurysms successfully embolized using N-butyl cyanoacrylate glue, with or without the adjunct use of coils.

Article Synopsis
- Undifferentiated embryonal sarcoma of the liver is a rare cancer mostly affecting children, and is even less common in adults; proper imaging is crucial to avoid misdiagnosing it with more common liver masses.
- A 37-year-old Chinese woman presented with abdominal pain and underwent multiple imaging tests revealing a cystic-solid liver nodule, initially thought to be benign.
- The definitive indication of malignancy came from a PET-CT scan, which showed abnormal F-fluorodeoxyglucose uptake, prompting the correct diagnosis of undifferentiated embryonal sarcoma of the liver.
