Spontaneous dissecting aneurysm of the extracranial internal carotid artery is uncommon, and simultaneous onset of multiple dissecting aneurysms is rare in patients without congenital or traumatic risk factors. A few reports suggest that extracranial internal carotid artery dissecting aneurysms can grow after SAH due to another intracranial dissecting aneurysm. The present report describes two ...

The choice of therapeutic strategy for intracranial dissecting aneurysm is often based on radiographic features, including characteristic geometry (e.g., irregular stenosis, segmental stenosis, aneurysm formation [pearl-and-string sign]), irregular fusiform or aneurysmal dilation, double lumen, and tapering occlusion. However, there is often a discrepancy between preoperative radiographic data ...

BACKGROUND AND PURPOSE Dissecting vertebrobasilar aneurysms are challenging to treat, and standard treatment modalities remain controversial. We retrospectively evaluated our experience using endovascular techniques to treat these aneurysms. MATERIALS AND METHODS From February 1997 to December 2007, 42 patients with intradural vertebrobasilar dissecting aneurysms underwent endovascular treatm...

BACKGROUND AND PURPOSE Dissecting aneurysms of the distal segment of the PICA are rare. The purpose of this study was to evaluate the clinical presentations, imaging features, treatment options, and clinical outcomes of dissecting PICA aneurysms. MATERIALS AND METHODS Six patients with dissecting aneurysms in the distal segments of PICA were found in the database of a single medical center, f...

Intracranial vertebral artery (VA) dissecting aneurysms often present with severe subarachnoid hemorrhage (SAH) and a subsequent high rate of mortality. We retrospectively studied the treatment efficacy and outcomes of 26 patients with ruptured VA dissecting aneurysms treated with endovascular surgery. Twenty-six patients with ruptured VA dissecting aneurysms were enrolled. Fifteen patients pre...

an appendix duplex was found on a routine dissection, in the dissecting room of the anatomy department of the faculty of basic medical sciences of the university of tehran. no other anomaly was noticed on the cadaver.

Dissecting cellulitis of the scalp is a rare inflammatory disorder unknown etiology. It clinically characterized by formation painful suppurative chronic nodules and abscesses, which are connected fistulae that, although they can be cured, as consequence leave patients with irreversible alopecia. Currently, there only few cases reported in literature. Here we present case 45-year-old patient di...

•The second case of cotyledonoid dissecting lipoleiomyoma documented in the literature is reported.•Cotyledonoid dissecting leiomyoma presents in a similar manner as aggressive malignancies; however, it is a benign lesion.•Recurrence of cotyledonoid dissecting leiomyoma is exceedingly rare with only one documented recurrence following conservative treatment.
