INTRODUCTION: Persistent Müllerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis...

Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The Adrenal Incidentaloma (AI) is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1...

Hypoperfusion is the typical perfusion pattern associated with recent small subcortical infarcts of the brain, but other perfusion patterns may be present in patients with these infarcts. Using CT perfusion, we studied 67 consecutive patients who had a small subcortical infarct at a follow-up MRI study to investigate the correlation between the perfusion pattern and the clinical and radiological course. On CT perfusion map analysis, 51 patients (76%) had focal hypoperfusion, 4 patients (6%) had hyperperfusion and the remaining 12 patients (18%) showed no abnormalities...

REVIEW
R D Blossey, C Krettek, E Liodakis
Forearm fractures are common in all age groups. Even if the adjacent joints are not directly involved, these fractures have an intra-articular character. One of the most common complications of these injuries is a painful limitation of the range of motion and especially of pronation and supination. This is often due to an underdiagnosed torsional deformity; however, in recent years new methods have been developed to make these torsional differences visible and quantifiable through the use of sectional imaging...

BACKGROUND: The non-fusion pedicle-screw system Dynesys stabilization(DS) for lumbar degenerative disease aims to better preservation of range of motion(ROM) than fixation and fusion systems. However, decreased ROM and unexpected facet fusion at the index level were observed after DS applied with unknown etiology. The aim of this study is using radiological parameters to explain the phenomenon of facet arthrodesis. METHODS: The patients who underwent surgery for L4-5 spinal stenosis were sorted retrospectively into two groups: the DS, and the microdisectomy(MicD) groups...

Cavernous hemangiomas are the most common benign orbital tumors in the orbit, but radiological differentiation from other solitary orbital masses can still be challenging at times. While there have been previous studies describing the radiological characteristics of cavernous hemangiomas on computed tomography (CT) and magnetic resonance imaging (MRI), there have not been any studies comparing the 2 imaging modalities. The purpose of our study was to evaluate CT and MRI findings of orbital cavernous hemangiomas and compare both modalities...
