Persistent trigeminal artery (PTA) is a rare cerebrovascular variation of remnant fetal carotid-vertebrobasilar anastomoses. The PTA variant terminates in the cerebellar artery with no direct connection to the basilar artery. We present a rare case of a PTA variant that terminated directly into the ipsilateral posterior inferior cerebellar artery.

Nasal anatomic variations are relevant during nasal surgical and endoscopic procedures. The extent of imaging methods, such as the cone beam computed tomography (CBCT), allows a better characterization of such peculiar anatomic traits. The bifid inferior turbinate (BIT) is a rare finding, being previously reported less than ten times. It was found and described on CT scans of patients, being usually associated with the absence of the uncinate process (UP). We hereby report for the first time a bilateral true BIT which differs from the previously reported BITs by the fact that the UPs were present and the bifidity was oriented laterally...

INTRODUCTION: Soft tissue defect on lower limb can result in an intractable wound. Surgeons resort in flaps to cover these injuries. Including fascia as in the case of a fasciocutaneous flap increases survey of the flap. Rising a perforator flap avoids to sacrifice a major vessel whence the nourishing perforator artery is born. We wanted to explore suprafascial distribution of the fibular skin perforator arteries supposing possible to find out a vascular axis composed of anastomoses of the fibular perforator vessels...

INTRODUCTION: Major anatomical textbooks generally state that the biceps brachii muscle (BB) is composed of long and short heads, whereas the brachialis muscle (BR) consists of a single head. However, the numbers of heads comprising the BB and the BR are very variable. The purpose of this study was to investigate how the branching patterns of the musculocutaneous nerve (MC) influence the number of heads of the BB and the BR. MATERIALS AND METHODS: Morphological examinations of the BB and MC were conducted using cadavers of 22 Japanese individuals, and morphological examinations of the BR and the MC were conducted in 9 of those 22 individuals...

BACKGROUND AND IMPORTANCE: The median sacral artery (MSA) is a relatively small vessel that always arises from the posterior, terminal part of the infrarenal aorta. In most cases, the MSA runs behind the iliocaval junction. Here, we describe a very rare case of an MSA running in front of this junction. CASE REPORT: During a human cadaveric dissection of the retroperitoneal area, we unexpectedly observed that the MSA passed in front of the left common iliac vein...

PURPOSE: Literature includes a number of studies using structural MRI (sMRI) to determine the volume of the amygdala, which is modified in various pathologic conditions. The reported values vary widely mainly because of different anatomical approaches to the complex. This study aims at estimating of the normal amygdala volume from sMRI scans using a recent anatomical definition described in a study based on post-mortem material. METHODS: The amygdala volume has been calculated in 106 healthy subjects, using sMRI and anatomical-based segmentation...

PURPOSE: The pterygopalatine fossa is one of the most complex anatomical regions to understand. It is poorly visualized in cadaveric dissection and most textbooks rely on schematic depictions. We describe our approach to creating a low-cost, 3D model of the pterygopalatine fossa, including its associated canals and foramina, using an affordable "desktop" 3D printer. METHODS: We used open source software to create a volume render of the pterygopalatine fossa from axial slices of a head computerised tomography scan...

PURPOSE: Advanced imaging modalities, such as multi-slice computed tomography (MSCT) and cone beam computed tomography (CBCT), greatly facilitate diagnostic medicine. In radiological research, it is important to know how accurately a scanned object is visualized, and whether the methodology leads to image distortion. The objective of this study was to evaluate whether formalin fixation impacted the accuracy of virtual 3D bone models generated via CBCT and MSCT using a software-based evaluation method that excluded human measurement errors...
