[The role of MRI in the clinical examination following breast cancer screening]

SZABÓ Éva, BIDLEK Mária, GŐDÉNY Mária

[INTRODUCTION - Breast cancer screening was performed in 27 325 female patients at the National Institute of Oncology from 1st of January 2002 to May 30th of 2005. Complementary examinations were necessary in 1876 women. MR-mammography was performed in 65 of these cases. We were curious about in which cases MR mammography helps to make the diagnosis more accurate, how does it influence the therapy. We also studied, whether the number of surgical interventions because of benign breast lesions decreases due to MR mammography. PATIENTS AND METHODS - In 65 patients MR mammography was performed using non-contrast axial and coronal T1W and STIR sequences. After the injection of gadolinium four series of 3D FLASH (fast low angle shot) dynamic gradiens echo sequences were also applied. Subtraction of the non-contrast and contrast enhanced series were evaluated in addition to the intensity curves of the postcontrast series. RESULTS - MR mammography helped to evaluate dense breasts in 21 cases, to identify multifocal lesions in 6 cases and to differentiate the malignant-benign processes. In the course of the 65 post-screening examinations, malignant processes [BI-RADS IV-V (Breast Imaging Reporting and Data System)] were diagnosed in 21 cases, benign processes (BI-RADS II-III) or negative results were found in 44 patients. CONCLUSION - MR mammography increased diagnostic accuracy, decreased the number of benign lesion-related surgical procedures and increased the accuracy in determining surgical radicality and establishing a therapeutic plan.]

[Acromesomelic dysplasia du Pan]

ALI Al Kaissi, MAHER Ben Ghachem, FARID Ben Chehida, KAZIMIERZ Kozlowski

[INTRODUCTION - Cartilage derived morphogenic protein (CDMP1) mutations account for several related disorders, ranging from prenatal lethal to very mild entities such as brachydactyly C. Two similar severe manifestations of CDMP1 mutations are du Pan and Hunter-Thompson syndromes. CASE REPORTS - We report two second degree relatives with du Pan syndrome. Clinical history and full skeletal surveys were analysed and compared with the data from the literature. Frequent spontaneous abortions - probably manifestation of the lethal forms of CDMP1 mutations - were present in both families. Skeletal surveys of the patients showed similar acromesomelic abnormalities consistent with du Pan syndrome. CONCLUSION - The rare publications of du Pan syndrome present usually insufficient radiographic documentation. Better radiographic imaging is necessary to establish clear-cut criteria of differentiation between du Pan and Hunter-Thompson syndrome.]

[Calcification of the tentorium cerebelli]

BILONKA Viola, BENDE Mariann

[A 16-year-old female patient with high temperature and headache was hospitalized because of suspicion of meningitis. Cranial CT showed a mild hydrocephalus, massive falx calcification and calcification in the projection of the tentorium. Excluding several well known reasons of the calcification the findings was thought to be a physiological variation. The child recovered after some days and left the hospital. The authors based on prior publications on tentorium calcification consider this finding a physiological-phylogenetic origin.]

[Intracystic brachytherapy of cystic brain tumors by image fusion method- intracavital beta irradiation of 90-Yttrium solution]

BALLÁNÉ PERDUK Anikó, JULOW Jenő

[Aim of the research: The authors aimed to gain acceptance, effectiveness testing and the timetable of the shrinking of the cysts for the treatment procedure of patients with cystic craniopharyngeoma. The procedure utilizes intracavitary beta irradiation by 90Y colloidal solution. Image fusion was used for the first time for the guidance and control of the intra cystic irradiation of brain tumors. The authors also examined the use of the image fusion for brachytherapy of brain tumors before, during, and months or even years after surgery and to patient follow up. Research and sampling methods: 130 craniopharyngeoma cyst was irradiated with the Yttrium-90 colloidal solution in 84 patients. The internal wall of the cyst were getting a load of 180-300 Gy. The volumes of the cysts were followed almost over 30 years by the control of CT-MRI image fusion. For the planning of the irradiation the authors developed their own software and BrainLab was used for the CT-MRI-PET image fusion. For the mathematical and statistical calculation Matlab and MedCalc soft wares were utilized. Results: The results were from 130, 90Y β stereotactic intracavitary irradiation of cystic craniopharyngiomas. As per cystic CRF volume the volume reduction exceeded 80 %. The mean survival rate following 90-Y irradiation was 7.5 years. Large-scale shrinkage of craniopharyngioma cysts were observed significantly, following 6 months. Conclusions: According to long term clinical experience the intracavitary 90 Yttrium brachytherapy is a relatively non-invasive and effective mode for the recurrent cystic craniopharyngeoma therapy. Procedures where isotope get implanted, qualify in all aspects of a minimally invasive therapy.]
