BACKGROUND: Maxillary posterior tooth region is an important area with respect to periapical surgery, implant placement, and sinus lifts. Posterior superior alveolar artery (PSAA) is located on the lateral wall of maxillary sinus and may become injured during such surgical procedures. Therefore, knowledge of the subject is essential to a clinician. The goal was to determine the anatomical relationship of posterior superior alveolar artery to the floor of maxillary sinus and alveolar crest...

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis with a prevalence rate of seven per million. Cardiac involvement was reported in 20-50%, yet with improved diagnostic methods, the frequency of cardiac involvement is expected to be even higher. It can result in significant morbidity and mortality, accounting for about 50% of death. Cardiac magnetic resonance (CMR) imaging is used to evaluate the myocardium, valves, coronary arteries, pericardium, also to assess cardiac structure and function...

BACKGROUND: Acute appendicitis is an emergent surgically treated disease generally represented by right lower abdominal pain. The most common location of the appendix is descending intraperitoneal. However, it can also show atypical locations such as inguinal canal, femoral canal, subhepatic, retrocecal, intraperitoneal abdominal midline and left side in situs inversus or intestinal malrotation patients. Atypical location can lead to atypical clinical presentations. Ultrasonography is the first choice modality for imaging...

BACKGROUND: Patients with Nutcracker syndrome generally present with nonspecific abdominal pain, with the left renal vein (LRV) lodged between the aorta and the superior mesenteric artery. In rare cases this can result in atypical gastrointestinal symptoms, making the diagnosis of Nutcracker syndrome challenging. CASE REPORT: A 28-year-old female patient presented with complaints of severe abdominal pain and palpable pulsatile abdominal mass located in the left epigastric area...

Computed tomography (CT) is a frequently performed examination in women of all ages. In all thoracic CT examinations of the chest at least parts of the breasts are included. Therefore incidental breast pathology may be observed. It has been suggested that one out of 250 women undergoing chest CT will show a malignant incidental breast lesion. Given the high number of performed chest CT examinations, this contributes to a significant number of malignancies. In this review, after a brief discussion of the value of computed tomography in breast imaging, normal and pathologic findings are discussed to create awareness of this potential "black box" on chest CT...

BACKGROUND: HWW syndrome is a very rare congenital anomaly of urogenital tract involving Mullerian ducts and mesonephric ducts. It is characterised by a triad of symptoms - uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. It can be classified based on a completely or incompletely obstructed hemivagina. It presents soon after menarche or shows delayed presentation depending on the type. It can exhibit acute pelvic pain shortly after menarche and may show non-specific and variable symptoms with resultant delay in diagnosis...

BACKGROUND: The effects of the reduction of low-energy X-ray spectrum on lung perfusion images created by dual-energy CT have not been well evaluated. The aim of this study is to investigate the reliability of lung perfusion blood volume (PBV) images created by dual-energy CT (DECT) equipped with or without a tin filter, focusing on its accuracy adjacent to high-attenuation areas. MATERIAL/METHODS: Among 176 patients who underwent DECT for suspicion of pulmonary embolism, 38 patients (mean age, 64; range, 16 to 83 years) without apparent evidence of pulmonary embolism were evaluated in this study...

BACKGROUND: Diagnostic upper gastrointestinal (UGI) endoscopy has been regarded as a safe procedure. CASE REPORT: We report of a 67-year-old woman who developed epigastric pain and dyspeptic complaints following an uneventful upper gastrointestinal endoscopy. The diagnosis of an acute reversible duodenitis was made on the basis of imaging studies. A duodenal diverticulum was also found on CT images, which raised the suspicion that duodenal diverticulum could be a predisposing factor for duodenitis...

BACKGROUND: Primary intracranial hydatid cyst is a rare location of human echinococcosis whose spontaneous, traumatic or even iatrogenic rupture, as in case of misdiagnosis, may cause anaphylactic reactions and dissemination. CASE REPORT: We discuss the management of a 9-year-old boy who was admitted to our Emergency Department with an intracranial hypertension syndrome. Head CT scan and brain MRI showed a huge intra-axial right temporo-parieto-occipital cyst with a marginal calcification, associated with left ventricular uncompensated hydrocephalus...

BACKGROUND: The classical theory of Müllerian origin of upper vagina fails to explain complex urogenital malformations like OHVIRA syndrome; the Acien's hypothesis, however, unravels the hidden embryopathogenesis. As per Acien, Wolffian (mesonephric) ducts instead of Müllerian ducts and sinovaginal bulbs, give rise to the vagina. The new hypothesis, however, retains the concept of origin of the ureters (with ureters inducing renal development) by the former and the uterus by Müllerian ducts...

BACKGROUND: MRCP is the method of choice in diagnosing pathologies of the biliary system. One of them is bile fistulae. They are uncommon but tend to cause many diagnostic problems. The possible way to improve MRCP is using it with intravenous injection of hepatobiliary-specific contrast agents. As it is eliminated via the hepatobiliary system, it can be visualized in the bile ducts and may help to reveal disorders undetected by a standard MRCP. CASE REPORT: We report a case of a 36-year-old woman with leakage in the biliary system which led to creation of a subcutaneous bile reservoir...

BACKGROUND: Renal artery stenosis is a common cause of secondary hypertension refractory to medical therapy. Percutaneous angioplasty along with metallic stent placement has been described as an effective treatment for revascularization of the renal artery. CASE REPORT: A 54-year-old woman affected by paranoid schizophrenia with a history of hypertension and chronic renal failure due to renal artery occlusion was treated by endovascular recanalization and stent placement that resulted in improvement of renal function and control of hypertension...

BACKGROUND: A cerebral spinal fluid (CSF) cavity within the conus medullaris has been described by the term ventriculus terminalis (VT) or the fifth ventricle. The finding of a VT on MRI imaging of the lumbar spine is often incidental but may be found in patients with low back pain or neuromuscular deficits. These lesions, when identified, are thought to regress or remain stable in terms of size, although some have been described to enlarge in the presence of post-traumatic meningeal hemorrhages or deformities of the vertebral canal...

BACKGROUND: Diaphragmatic injuries occur in 0.8-8% of patients with blunt trauma. The clinical diagnosis of diaphragmatic rupture is difficult and may be overshadowed by associated injuries. Diaphragmatic rupture does not resolve spontaneously and may cause life-threatening complications. The aim of this study was to present radiological findings in patients with diaphragmatic injury. MATERIAL/METHODS: The analysis of computed tomography examinations performed between 2007 and 2012 revealed 200 patients after blunt thoraco-abdominal trauma...
