OBJECTIVE The purpose of this study was to assess the role of MRI in the preoperative characterization and local staging of testicular neoplasms. SUBJECTS AND METHODS MRI was performed on 33 patients referred because a testicular mass had been detected clinically and sonographically. Both T1- and T2-weighted sequences were performed with a 1.5-T MRI unit.(More)
Testicular lymphoma represents the commonest testicular malignancy in men older than 50 years. MR imaging of the scrotum is an efficient supplemental diagnostic tool in the evaluation of scrotal diseases. We report two cases of primary diffuse large B-cell testicular lymphoma, presented in men over the age of 50 years. MR imaging revealed the presence of a(More)
OBJECTIVE To evaluate the magnetic resonance imaging (MRI) findings of hand involvement before and 1 year after treatment in patients with early rheumatoid arthritis (RA). METHOD MRI of the dominant hand was performed in 22 patients fulfilling the new criteria for early RA. The patients were divided into three groups. Nine had very early RA (VERA; disease(More)
Malignant transformation is a rare complication of endometriosis. MR criteria for diagnosis include the presence of soft-tissue components, enhancement after contrast material administration in an endometriotic cyst. We present the multidetector CT and MR imaging findings in a case of an incidentally found endometrioid adenocarcinoma in a left-sided ovarian(More)
RATIONALE AND OBJECTIVES The purpose of our study was to evaluate the multidetector computed tomography (MDCT) features of benign adnexal lesions. METHODS AND MATERIALS We report the MDCT features of 68 histologically proven benign adnexal lesions. Pathologic diagnoses were nonneoplastic adnexal cysts (n = 16), endometriomas (n = 12), serous or mucinous(More)
INTRODUCTION The vast majority of paratesticular masses are benign. Magnetic resonance imaging of the scrotum may provide valuable information in the pre-operative work-up of scrotal masses, by allowing the precise localization of the lesion and helping in characterizing its nature. Diffusion-weighted magnetic resonance imaging is an evolving technique that(More)
Although uterine leiomyomas are the most common neoplasms of the female genital tract, this is not the case when referring to women under the age of 20. Only a few cases of uterus leiomyomas have been reported in this age. Preoperative imaging evaluation is mandatory in adolescent women for the accurate detection, localization, and characterization of(More)
OBJECTIVES To assess the apparent diffusion coefficient (ADC) changes of the normal uterine zones among reproductive women during the menstrual cycle. METHODS The study included 101 women of reproductive age, each with regular cycle and normal endometrium/myometrium, as proved on histopathology or MR imaging examination. Diffusion-weighted (DW) imaging(More)
A 74-year-old man underwent multidetector CT virtual cystoscopy due to macroscopic hematuria. A large, irregularly-surfaced, solid bladder mass was detected, infiltrating the perivesical fat, the seminal vesicles and the prostate. CT examination of the chest and abdomen showed no distant metastases. Radical cystectomy was performed and pathology reported(More)
The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and ovary are extremely rare. There are a few reports in the English literature of synchronous primary malignancies of the kidney and the ovaries, but no data regarding their imaging features. We present a case of an elderly(More)
