RESUMEN
Calyceal diverticulum is an eventration of the upper collecting system within the renal parenchyma. This nonsecretory outpouching is lined by transitional epithelium and communicates with the main collecting system via a narrow channel. Tumor growth arising from a calyceal diverticulum is rare, and primary squamous cell carcinoma arising from a calyceal diverticulum has never been described in literature. Herein, we report a case of primary squamous cell carcinoma arising from a calyceal diverticulum and present initial imaging of a benign-appearing cystic lesion.

BACKGROUND: Chyluria is caused by rupturing of lymphatic varices into the pyelocaliceal system. Although Chyluria is rare in western countries, it is not uncommon in Asia. We would like to present the experience of diagnosis, evaluation and treatment of chyluria in Taipei Veterans General Hospital. METHODS: From 1973 to 1999, a total of 30 patients with chyluria were reviewed. All had the chief complaint of milky white urine passage. They were investigated by multiple workup modalities including computed tomography, intravenous urography, lymphangiography, and cystoscopy. Fifteen cases received 1% silver nitrate instillation and 4 cases underwent nephrolysis either as primary or salvage treatment. RESULTS: Lymphangiography was performed in 24 of the 30 cases and responsible causes of chyluria were noted in 21. They were followed up for at least 12 months in 9 patients treated by intrarenal pelvic instillation of silver nitrate and 3 by nephrolysis, respectively. Recurrence was found in 1 patient (11.1%) receiving silver nitrate only and no significant adverse effect was noted. CONCLUSIONS: Lymphangiography is the most powerful diagnostic tool. Intrarenal silver nitrate instillation is a safe and effective management of chyluria.

We report the case of an 18-year-old man who presented with traumatic trapped penis after a motorcycle accident. Ultrasonography (US) and CT scan disclosed a trapped penis buried within the prepubic fat. Imaging findings of the traumatic trapped penis and the role of imaging study for this rare clinical condition are discussed.
