During dissection of a 75-year-old Caucasian female cadaver, a trifid superior transverse scapular ligament (STSL) was found. The suprascapular nerve and vessels ran inferior to the STSL though the suprascapular notch. Measurements of the structures of the suprascapular region were taken using two complementary but independent methods: a classical method using an electronic digimatic calliper and a new one based on an analysis of digital photographic documentation of the STSL. The knowledge of anatomic variations of the STSL is important because this structure is the most commonly recognised possible predisposing factor of suprascapular nerve entrapment and can be helpful in diagnosis and surgical and arthroscopic treatment of this pathology.

The vertebrobasilar system is a part of the cerebral arterial circle (circle of Willis), which forms the collateral circulation of the brain. A 75-year-old Caucasian female was admitted to hospital because of a strong headache radiating to the neck. On the basis of a neurological examination, the patient was classified into group III of the Hunt and Hess scale. Subarachnoid haemorrhage and 2 aneurysms of the cerebral arteries were diagnosed during multidetector 64-row computed tomography and angiography. An asymmetrical fenestration of the proximal part of the basilar artery was also observed. The bleeding aneurysm locating at anterior communicating artery was diagnosed and clipped surgically by right fronto-parietal craniotomy. The second aneurysm was located just after the junction of the vertebral arteries on the wall of the basilar artery. The presented case firstly illustrates the asymmetric fenestration of the proximal part of the basilar artery coexisting with subarachnoid haemorrhage and 2 aneurysms of brain arteries. Such observation should increase diagnostic attention in the detection of possible associated aneurysms and can help in preventing complications during all endovascular treatment procedures.

Duplication of the inferior vena cava (IVC) is a congenital condition where there are 2 large vessels: right IVC (RIVC) and left IVC (LIVC) on both sides of the abdominal aorta. Here, we present 2 cases of duplicated inferior cava coexisting with rare morphology of left gonadal (ovarian/testicular) vein. Both were observed during multidetector 64-row computer tomography. In first case atherosclerotic, tortuous abdominal aorta models both inferior venae cavae. The shape of veins were more- (RIVC) and less-arcuate (LIVC). Two years ago, the patient had been diagnosed with pulmonary thromboembolism. In second case abdominal aortic aneurysm models both large veins. The RIVC has a highly right-arcuate shape, while the LIVC has a less left-arcade shape. Our observation would seem to be especially important, because the tortuous abdominal aorta changes the shape of both IVC, and may predispose them for thrombosis formation. The presented report precisely describes the topography and measurements of the vessels in the retroperitoneal area. The literature concerning this anomaly, potential clinical implications and vascular complications are reviewed and the possible practical aspects are discussed. A familiarity with the anatomy of the most common types of venous anomalies is crucial for all surgeons, urologists and oncologists to reduce the risk of severe haemorrhage during all abdominal procedures.

The linea aspera is a roughened, longitudinally oriented, irregular crest composed of two lips located on the posterior surface of the femoral shaft. The purpose of this research was to investigate the morphological variations of the linea aspera in humans. The study was carried out on 90 femurs. Osteometric measurements of the bones were taken using two complementary methods: classical osteometry and a new one based on the analysis of digital photographic documentation of the femur using MultiScanBase v.18.03 software. The analysis allowed four types of linea aspera to be determined: parallel (type I 27.2%), concave (type II 25.7%), convex (type III 5.7%), and variform (type IV 41.4%). The frequency of the each type in females and males was also described. A better knowledge of the anatomical variations of the linea aspera may be helpful in orthopaedy and radiology to distinguish pathological from normal anatomical variations.

The aim of this research was to investigate if perennial, professional weightlifting training, started at puberty, leads to hypertrophy of the patellar ligament (PL). The knee examinations were performed with a 1.5 T magnetic resonance imaging system. The area of the cross-sectional area (CSA) of the PL midsubstance was evaluated in T1-weighted images. A control group of 19 participants was also examined with the same protocol. A significant increase of the PL midregion CSA was observed in a group of weightlifters. The area of the PL midsubstance and the onset of training were very strongly, reversely correlated. This paper presents the first description of PL midregion hypertrophy due to professional weightlifting training initialised and continued from a pubertal spurt. The described overgrowth is more intensified than has been reported for other parts of the PL. Moreover, it has been observed in the region that is the least susceptible for injuries, which in another situation could also have led to increased volume of the PL. The described phenomenon should be considered by orthopaedic surgeons because it can influence the choice of the surgical technique for cruciate ligament reconstruction as the PL is one of the structures for harvesting autografts.

Background: Coronary computed tomography angiography (CCTA) is helpful in making a precise noninvasive evaluation of coronary anatomy, allowing concomitant evaluation of other cardiac structures. The aim of this study was to determine the prevalence of coronary artery variations detected by 64-slice mutidetector CT. Materials and methods: The results of ECG-gated CCTA in 726 consecutive patients (mean age 58 years) were analysed retrospectively. The main indications for CCTA were atypical chest pain, angina pectoris, screening for coronary artery disease and determination of the patency of bypass grafts or stents. Acquisition was performed with a 64-detector CT scanner with retrospective ECG gating. Imaging results were assessed by experienced cardiovascular radiologist. Results: The overall incidence of coronary artery anomalies was 1.1% (8 out of 726 participants). The most common anomaly was an anomalous origin of the circumflex artery from the right coronary sinus with a retroaortic course (4 patients, 0.6%), followed by origin of right coronary artery from the left coronary sinus (2 patients, 0.3%). One patient with abnormal origin of the left main artery from the right coronary sinus (0.1%) and 1 patient with a circumflex artery origin from the proximal segment of the right coronary artery (0.1%) were observed, both with retroartic course. Conclusions: CCTA is a noninvasive imaging technique useful for the precise evaluation of variations of the coronary arteries. This study shows similar results to other reports on this subject.

Background: The suprascapular notch is a clinically important site because it is the main site of injury and compression of the suprascapular nerve. Its shape and size are the most important factors in the aetiopathology of suprascapular nerve neuropathy. This article reports the first computed topography (CT) study on the correlation between the diameters of the suprascapular notch and anthropometric measurements of the human scapula. Materials and methods: A total of 130 scans of shoulders by a helical 32-row multidetector CT scanner were retrospectively analysed. The following scapular measurements were performed: morphological length, morphological width, projection length of the scapular spine, maximal width of the scapular spine, length of the acromion, maximal length of the coracoid process, length of the superior border of the scapula, morphological height of the supraspinous fossa, length of the lateral border of the scapula, and morphological height of infraspinous fossa. The following suprascapular notch dimensions were measured: maximal depth, superior transverse diameter, middle transverse diameter. Results: The maximum depth of the suprascapular notch correlates with the morphological length of the scapula, the length of the lateral border of the scapula and the morphological width of the scapula. The superior transverse diameter of the suprascapular notch correlates with the length of the superior border of the scapula and negatively with the length of the lateral border of the scapula. In addition it has been shown that the length of the superior border of the scapula correlates more closely with the superior transverse diameter of the suprascapular notch than the middle transverse diameter of the suprascapular notch. Conclusions: It could be supposed that humans with longer scapulae have deeper notches. It may be also concluded that scapulae with a wider superior border have a shallower suprascapular notch.

Congenital anomalies of systemic veins are usually asymptomatic and found incidentally during ultrasonography, computed tomography (CT) or magnetic resonance examinations performed for other clinical indications. Persistent left superior vena cava (PLSVC) with absent right superior vena cava (RSVC) is the congenital aberration in the thoracic venous system which occurs in only 0.09% to 0.13% of patients who have congenital heart defects. In this paper, we present the extremely rare case of a 72-year-old male with PLSVC associated with an absence of RSVC, referred for coronary CT angiography. Multidetector CT angiography is a powerful tool for the detection of venous anomalies, which is essential before invasive procedures such as the implantation of pacemakers.
