BACKGROUND: Sacrum is a triangular bone placed in the base of the spine and formed by the synostosis of five sacral vertebrae (S1-S5). Its upper part is connected with the inferior surface of the body of L5 vertebra forming the lumbosacral joint, while its lower part is connected with the base of the coccyx forming the sacrococcygeal symphysis, an amphiarthrodial joint. The existence of four pairs of sacral foramen in both anterior and posterior surface of the sacrum is the most common anatomy...

Identification of taxonomy at a specific level is time consuming and reliant upon expert ecologists. Hence the demand for automated species identification increased over the last two decades. Automation of data classification is primarily focussed on images, incorporating and analysing image data has recently become easier due to developments in computational technology. Research efforts in identification of species include specimens' image processing, extraction of identical features, followed by classifying them into correct categories...

BACKGROUND: Congenital rib abnormalities are found in approximately 2% of the general population. Usually, they occur in isolation, when they are rarely symptomatic, but they can also associate with other malformations. MATERIALS AND METHODS: We reviewed imaging examinations performed over a period of two years (2014-2015), enabling us to identify isolated rib abnormalities in six adult patients. RESULTS: The case series consisted in three cases with bilateral cervical ribs and one case each with bifid rib, costal fusion and rib pseudarthrosis...

Post-fixation of sections is especially required for cryostat sections of fresh frozen tissues. Vimentin is an intermediate filament in both fibrillary and non-fibrillary form, expressed in Müller's cells and astrocytes of the retina. Our aim was to determine the best post-fixation method for visualizing vimentin in archival mouse eyes. We used an archival mouse eye, slightly prefixed with paraformaldehyde and stored at -80°C for 4 years. We tried three fixatives (paraformaldehyde (PFA), alcohol / acetic acid (AAA) and methanol) for post-fixation of eye sections...

The digastricus and omohyoideus muscles are digastric muscles with two muscle bellies. An insertion tendon of the posterior belly becomes an intermediate tendon in digastricus muscles, whereas a single band-like muscle in omohyoideus muscles may later be interrupted by an intermediate tendon, possibly due to muscle cell death caused by mechanical stress. In human fetuses, an intermediate tendon provides the temporal origins of the tensor veli palatini and tensor tympani muscles. Some reptiles, including snakes, carry multiple series of digastric-like axial muscles, in which each intersegmental septum is likely to become an intermediate tendon...

Pelvic rib is a rare anomaly where ectopic rib is found in a pelvic region. It is usually found occasionally in asymptomatic patients. We report a case of 15 years old male, diagnosed with a symptomatic pelvic rib. It had an unusual presentation creating a pseudotumor associated with pain and reduced range of motion in the hip joint. Patient was operated on with good result and final diagnosis was confirmed in pathological examination.

Variations of the arterial and venous system of the abdomen and pelvis have important clinical significance in hepatobiliary surgery, abdominal laparoscopy, and radiological intervention. A case of double inferior vena cava (IVC) with complex interiliac communication and variation of the common hepatic artery (CHA) arising from superior mesenteric artery (SMA) in a 79-year-old male cadaver is presented. Both IVCs ascended on either side of the abdominal aorta. The left-sided IVC crossed anterior to the aorta at the level of the left renal vein...

Diving goiters can descend the cervical region expanding directly into the thoracic cavity. In most cases, diving goiters extend into the anterosuperior compartment, but they may also extend behind the trachea. We herein present a case of a male patient with retrotracheal goiter and history of left thyroid lobectomy and median sternotomy for thoracic aortic aneurysm repair with graft placement. After detailed preoperative evaluation, the patient underwent surgical resection of the mass through a combined approach; the existing cervical incision and a right posterolateral mini-thoracotomy...

The orbit is very frequently damaged by traumas which results in not only with bone deficits, but also with functional deformities if reconstruction is not appropriate. Anatomical exposure of the bony orbit is of importance for both anatomists and surgeons who perform operation on this area. The current study evaluated the group of morphometrical parameters on 74 adult West Anatolian dry skulls and stereological surface area on the dry skull orbits while describing the clinical importance. Surface area on the orbital base of the skulls were also evaluated using stereological method, bilaterally...

BACKGROUND: The foramen magnum provides a transition between fossa cranii posterior and canalis vertebralis. Medulla oblongata, arteria vertebralis and nervus accessorius spinal part pass through the foramen magnum. In this study, we aimed to make the morphometric measurements of the foramen magnum on CT and to determine the feasibility of sex determination based on these measurements. Besides sex determination, from a clinical aspect, it is important to know the measurements of the foramen magnum in the normal population in terms of diseases characterized by displacement of the posterior fossa structures through foramen magnum to upper cervical spinal canal like Chiari Malformations and Syringomyelia...

The main aim of this paper is to present three cases of persistent (patent) primitive trigeminal artery, presence was incidentally revealed during various radiological examinations. The presence and function of these vessels in extrauterine life is sometimes associated with other vascular abnormalities e.g. aneurysms, hemangiomas, moyamoya disease but frequently found incidentally without any negative signs or symptoms. The presented cases of patients with primitive trigeminal artery clearly show that the reported ailments, which had made the diagnostic imagining necessary, were not associated with the patency of this artery...

Anatomy is the keystone to an appropriate understanding of surgical and radiological sciences. Here the authors report on a rare case of complete right- and left-sided thoracic ducts (TDs) associated with aberrant left-vertebral artery (LVA) arising from the aortic arch. The TDs originated from right and left cisterna chyli and terminated separately close to the left venous angle. Superior to the aortic arch, the TDs showed different relationships to the LVA; the right TD was ventral, while the left was dorsal in position...
