Anomalies of the aortic arch system may assume many different anatomic patterns. Some are only of academic interest; others are of extreme clinical importance and may at times constitute an emergency requiring prompt surgical intervention to save life. The anomalies of the aortic arch system which produce symptoms and which require surgical treatment are of three types. First, there are the “va...

A 4-year-old girl with a solitary vascular anomaly of the mesentery presented with acute lower abdominal pain. Despite the use of ultrasound, computed tomography scan and image-guided core biopsies, the lesion was initially mistaken for an inflammatory intra-abdominal mass. The correct diagnosis was made at laparotomy. Solitary vascular anomaly of the mesentery is rare and its presentation as a...

Fenestration of the vertebral artery is a rare vascular anomaly that has been observed at autopsy and on angiography. It is most commonly seen in the extracranial segments of the vertebral artery. This congenital anomaly can arise during multiple different stages of embryological development of the vertebral artery. The clinical significance is unclear, but multiple studies have reported associ...

Vascular anomalies are heterogeneous group of congenital lesions of abnormal vascular devel‐ opment and may occur anywhere on the body. There is a primary distinction between a vascu‐ lar tumor, which grows by cellular hyperplasia, and a vascular malformation, which represents a localized defect in vascular morphogenesis. Due to the differences in biologic be‐ havior and radiographic features, ...

Aberrant internal carotid artery (ICA) is a rare but a very important vascular anomaly of temporal bone. Misdiagnosis of the anomaly may lead to massive hemorrhage and severe complications during otologic procedures. It is essential to keep this anomaly in mind for any otologic surgeon to prevent catastrophic complications. We present a case of aberrant ICA appeared as a nonpulsatile middle ear...
