[INTRODUCTION - Ureter ectopy refers to the distal opening of the ureter at the site of the bladder neck or lower. 70-80% of the ectopic ureters are associated with pyelectasia and duplicated ureters. The incidence of this is 2-3 times higher in females. CASE REPORT - Following is a case report of a boy who was diagnosed with left-sided pyelectasia during a prenatal ultrasound scan. The postnatal ultrasound revealed a duplicated pelviceal cavity and ureter. The upper pole ureter and the pelvis demonstrated dilatation. At 8 months of age a left side heminehprectomy was performed. Two years postoperatively a follow-up ultrasound revealed a dilatation of the ureteral stump on the left side, which progressed. On MCUG the ureteral stump was identified inserting on to the proximal urethra. Cystography and MR urography demonstrated a ureteral stump which inserted on to the urethra. A repeat surgery was performed to remove the stump. Patient is symptom-free ever since. CONCLUSION - In ectopic, non-refluxing ureters long-term follow-up is necessary following heminephrectomy. A ureter stump besides the bladder can cause serious diagnostical difficulties. Also, it is possible that a dilating stump may lead to a reflux not identified earlier. MCUG and MR urography can help to clear delineate the pathology.]

[Technical aspects of MR urography based on two cases]

HORVÁTH László, BOGNER Péter, NAGY Gyöngyi, BAJZIK Gábor, VANDULEK Csaba, REPA Imre

[Intravenous urography has been the gold standard in diagnostic radiology studying the urogeintal system. However, ultrasound and other cross-sectional imaging methods have brought major change in this area. Beside modern (multislice) CT examinations the methods of MR urography are more frequently applied making possible both static and dynamic examinations beyond the wellknown advantages of MR imaging. The authors describe two complemetary methods of MR urography which provide a complete evaluation of the urinary system. The first method is aimed to image stationary fluid by using heavily T2 weighted turbo spin echo pulse sequences. This measurement well depicts the dilations of the excretory system even with little or no excretion of urine. The second method is analogous with the traditional IVU, as the excretion of a less nephrotoxic gadolinium based contrast medium followed by a T1 weighted gradient echo pulse sequence (possibly dynamic) helps to visualise the renal cavities and the urinary pathways. Normal renal function is a prerequisite when using this technique in order to visualise normal and obstructed urinary pathway disorders. The use of MR urography together with traditional MR methods may significantly reduce the number of invasive examinations and methods based on X-ray radiation exposure. MR urography may be exceptionally important in the uroradiological study of distensions of renal cavities in pediatric cases, pregnant women and renal transplant patients or in case of contrast material allergy.]

[The role of static MR-urography in diagnostics of urinary obstruction]

KIS Zsuzsanna, FAZEKAS Péter, KULCSÁR Dániel, KÖTELES Márta, KOVÁCS Annamária, MAGYAR Klára

[INTRODUCTION - The idea and methodology of MRurography has just crystallized recently due to the development of technology. The traditional MRU technology means the strongly T2 weighted sequence, suitable for depicting stationary liquid spaces. Its use is independent of the functional status of the kidneys thus it is suitable for depicting dilatated ureters in case of nonfunctioning kidneys, too. Authors's aim was to define the role of sMRU in the diagnostics of obstructive urinary diseases. PATIENTS AND METHODS - 60 sMRU examinations were performed on 59 patients using a 1.5 T Siemens Symphony MR scanner in the CT-MR Laboratory of the Markhot Ferenc County Hospital between May 1, 2003 and October 31, 2005. The sMRU was performed with 2D T2 TSE sequence with angiographic character. In each case, the examinations were completed with conventional sequences in multiple planes. The role of gadolinium enhanced T1-weighted MR urography in the same diseases was not studied. In 7 cases, low-dose thin slice CT examination was performed to reveal the precise cause of obstruction. The examinations were preceded by abdominal ultrasound or intravenous urography (IVU). RESULTS - Out of the 60 sMRU examinations uretery dilatation were observed in 50 cases. In the background of obstruction, stone could be detected in 13 patients, dilatation was observed in 4 patients and MR did not indicate stone. In 7 cases with known neoplastic disease, associated urinary obstruction could be detected. In the background of obstruction primary neoplasm was found in 10 patients unknown prior the MR examination. Other benign obstruction occurred in 13 cases. Obstruction was not proved in 10 patients. In these cases the examination was justified by uncertain ultrasound findings together with abnormal renal function parameters. Follow up sMRU was performed in one patient. False diagnosis was established in two patients, the cause of dilatation was not found in one patient. CONCLUSIONS - The sMRU examination can provide more precise detection of the causes of severe urinary obstructions. It helps to define the level of obstruction in case of known malignant tumors. The grade of urinary dilatation could be also evaluated. The sMRU examination in conjunction with conventional sequences in multiple planes made possible to set up a correct therapy plan.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.
