Complex tunica albuginea cyst simulating an intratesticular lesion.

Cysts of the tunica albuginea are uncommon lesions of the testis which in all reported cases have been benign. Complex cysts of the tunica albuginea can mimic intratesticular lesions, thus necessitating orchiectomy. We present a case of a complex tunica albuginea cyst which mimicked an intratesticular lesion at sonography, as well as at magnetic resonance imaging (MRI). Tangential views, however, suggested that this was in fact an extratesticular lesion. The use of tangential views, as well as knowledge of the appearance of the tunica albuginea at MRI, are important to make this differentiation in order to guide the management of these lesions. To our knowledge, this is the first case in which the appearance of a tunica albuginea cyst at MRI has been described.

Percutaneous pediatric renal biopsy: use of the biopsy gun.

A recently developed biopsy gun was used in the ultrasound (US)-guided biopsy of native kidneys in seven children. The biopsy gun employs a needle (18 gauge) smaller than that usually used for renal biopsies. In all seven cases it provided a core biopsy specimen that contained enough glomeruli to make a definitive histologic diagnosis of renal parenchymal disease. Use of the biopsy gun eliminated the more complicated movements needed to obtain samples with the conventional manual biopsy techniques. No major complications occurred, and in only one case a minor complication, trace hematuria determined by means of dipstick analysis, was found. The time required to obtain the tissue samples was decreased with use of this technique. Because of the advantages of the biopsy gun, the authors now use it exclusively in percutaneous US-guided biopsy of native pediatric kidneys and recommended that this method be considered by other institutions performing similar biopsies.

Three-dimensional computed tomography in maxillofacial trauma.

Roentgenographic evaluation of maxillofacial trauma is an integral component in the management of the acutely injured patient. Recent developments in computerized software permit three-dimensional computed tomographic (CT) reconstructions of complex anatomic parts. Five examples of complex maxillofacial trauma were demonstrated by conventional plain films, followed by two-dimensional and three-dimensional CT. Three-dimensional CT vividly demonstrates spatial relationships not easily conceptualized by present modalities.

Massive renal angiomyolipoma in tuberous sclerosis.

A massive renal angiomyolipoma, measuring 45 x 20 x 15 cm and weighing 3,500 g in a patient with tuberous sclerosis is presented. While renal angiomyolipomas may become quite large, this is one of the largest such tumors ever reported.

Leydig cell tumor of the testis in Klinefelter syndrome: MR detection.

Klinefelter syndrome is associated with the development of breast and extragonadal germ cell tumors in some patients. Leydig cell tumor in association with Klinefelter syndrome is a rare entity. We report such a case to illustrate the usefulness of MR imaging in detecting a testicular neoplasm when clinical examination and ultrasonography are equivocal.
