[The imaging staging follows the surgical FIGO staging system in the classification of gynecological carcinomas taking into account the extent of tumor invasion and lymphnode involvement. The most important prognostic factors which influence treatment are the presence of invasive disease and lymphnode metastasis. Imaging techniques for evaluation of gynecological tumor staging are: abdominal and transvaginal ultrasound, computed tomography and magnetic resonance imaging. Transabdominal ultrasound is not a reliable staging modality for gynecological tumors. Computed tomography is useful in the advanced III and IV stages of diseases, but differentiation between stages I and II is difficult. Magnetic resonance imaging showed excellent diagnostic accuracy in determining adnex masses, in the assessment of cervical as well as endometrial and ovarian cancer extension. Magnetic resonance imaging is superior in comparison to computed tomography and ultrasound, in both early and advanced stage disease. Evaluation of lymph-node involvement using computed tomography and magnetic resonance imaging rely only size criteria, which is not reliable indicator of tumor involvement.]

[MR imaging of acute disseminated encephalomyelitis and multiple sclerosis in children. A review (in English language)]

PATAY Zoltán

[Inflammatory diseases of the central nervous system (CNS) are relatively rare in children, but their relevance to public health is considerable due to frequent and significant long term morbidity and even mortality. As in adults, acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) and their variants are the most common entities in this group of pathologies in the pediatric patient population. Recent efforts have focused on establishing standardized diagnostic criteria schemes to facilitate the diagnosis and differential diagnosis of these diseases, however especially with multiple sclerosis those have not been fully validated yet for disease occurring in children. In recent decades the role of MRI has been constantly increasing in the diagnostic work-up of suspected inflammatory diseases of the CNS as well as in the follow-up of patients with confirmed disease. Currently, MRI is the first-line diagnostic imaging modality in ADEM and MS and is fully integrated in the most widely used diagnostic criteria schemes, but it has a key role in clinical therapeutic research trials as well. This paper provides an update on the current concepts and strategies of MRI in inflammatory diseases of the CNS, as well as a review of the imaging semiology of the various disease entities and variants with emphasis on clinical and imaging particularities relevant to the pediatric patient population.]

Marchiafava-Bignami disease: Report of three cases

GUNAY Gul, MESUDE Özerden, ZEYNEP Ozdemir, CAHIT Keskinkiliç, HAKAN Selçuk, BATUHAN Kara, AYSUN Soysal

Marchiafava-Bignami disease (MBD) is a rare alcohol-associated disorder characterized by demyelination and necrosis of the corpus callosum. We report three patients who had history of chronic alcoholism, different clinical presentation and MRI findings consistent with the diagnosis of Marchiafava-Bignami disease.

[Therapy of endometrial cancer - an update]

SIPOS Norbert

[Endometrial cancer is the most frequent gynecologic malignancy in developed countries. Recently, there is a signifi cant increase of incidence caused by epidemic obesity. While the etiology of endometrial cancer can be heterogeneous, the effective therapy should be rather personalized. The primary therapy of endometrial cancer is operative. The recommended surgery is total abdominal hysterectomy and bilateral salpingo-oophorectomy. Management of pelvic and paraaortic lymphadenectomy is supported by the latest international recommendations, except cases of low-risk tumors (stage I/A, grade 1 or 2, endometrioid type, diameter of tumor <2 cm). Method of adjuvant therapy, especially in developed stages, is still controversial. Efficacy of postoperative irradiation, chemotherapy and chemoirradiation is under investigation by several ongoing studies. Recurrent endometrial cancer has bad prognosis, the best solution in this case is chemotherapy. In recent years targeted therapy (especially antiangiogenetic drugs, mTORinhibitors and hormontherapy) gave us some promising results. Around 80% of endometrial cancers can be diagnosed at early stages and cured with efficacy. Unfortunately, there is a group of tumors with bad prognosis, low differentiation, or recurrency, which can be a real challenge for clinicians. In this review we discuss the latest and most promising studies and scientifi c results in connection with treatment of high-risk endometrial cancers.]

[Isolated gallbladder rupture following blunt abdominal trauma]

PÉTER Lívia

[INTRODUCTION - Gallbladder injuries following blunt abdominal trauma occur rarely and are usually associated with damage to other abdominal organs. Isolated rupture of the gallbladder is extremely rare. CASE REPORT - A 42-year old intoxicated male patient suffered a blunt abdominal trauma 4 days before the admission. The physical examination was of normal and no specific laboratory values were found. Ultrasound examination demonstrated the gallbladder with hyperechoic thickened wall and inhomogenous content. Beside of the gallbladder fluid collection was detected with irregular margins. To prove the diagnosis of gallbladder injury computed tomography was carried out. Break of the gallbladder wall and hight density lumen content, corresponding to blood was detected. Around the gallbladder an irregular fluid collection was seen, which reached the level of the transverse section of the mesocolon. Computed tomography excluded traumatic lesion of other parenchimal abdominal organs. Surgery confirmed the radiological diagnosis. CONCLUSION - The patient with isolated gallbladder injury had a multiphasic clinical course. Sometimes the diagnosis has to be established at a relatively asymptomatic stage. The basic methods of the diagnostics are the ultrasound examination and computed tomography.]

[MAGNETIC RESONANCE IMAGING IN ABDOMINAL DIAGNOSTICS]

PALKÓ András

[Magnetic resonance imaging (MRI) plays more and more important role in the abdominal imaging diagnostics since fast measurement sequences have become available making it possible to avoid movement artifacts and resulting in better quality and more informative images of the abdominal parenchymal organs and most segments of the gastrointestinal tract. The greatest advantage of MRI is that it is able to create images of adequate geometric resolution and excellent tissue characterization capacity without the use of ionizing radiation and iodinated contrast media. Today MRI is applied mostly in those cases when previous data suggest that computed tomography will not be informative or the results of recent imaging examinations (x-ray, ultrasound, computed tomography) do not provide sufficient diagnosis. Presumably MRI will be used with increasing frequency as the first or single best method of choice in the near future. Beased on these facts in abdominal diagnostics, MRI may be considered as a problem-solving modality which plays an outstanding role in the detection, differential diagnosis, staging and follow-up of many neoplastic and inflammatory lesions.]
