Objectives: To ascertain the potential utility of magnetic resonance imaging in providing additional clarification of those solid renal mass lesions identified at routine antenatal ultrasonography in early pregnancy and influencing the management of such lesions.
Methods: We present 7 patients in whom magnetic resonance imaging was used to diagnose, stage, and monitor renal lesions detected during pregnancy.
Results: Magnetic resonance imaging provided for improved imaging of renal mass lesions identified at antenatal ultrasonography, without the use of ionizing radiation, and permitted management determined by optimal radiographic assessment of such lesions without fetal irradiation.
We report a case of intravesical fat entrapment leading to failure of extraperitoneal bladder perforation to heal spontaneously. A 68-year-old woman underwent trans-abdominal hysterectomy complicated by an extraperitoneal bladder perforation. Despite prolonged catheterization, cystographic leakage persisted after 3 months.

Patients And Methods: In all, 17 patients had 18F-FMISO PET scans before nephrectomy for presumed RCC. Specimens were examined histologically, and immunohistochemistry was used to compare the microvessel density (MVD) as an indicator of angiogenesis in the tumour and normal parenchyma, in 15 patients.
