What do we see when we do not see the bladder? Review of the main urinary diversion techniques and their complications.

OBJECTIVE: To review the different types of urinary diversion surgeries (UDS) in order to recognize the expected findings in a postoperative study, using different imaging techniques. To recognize the main postoperative complications, both early and late. CONCLUSION: UDS are surgical procedures whose purpose is to redirect urine flow after cystectomy, generally in an oncologic context. The imaging evaluation of urological surgeries is often a radiological challenge, with CT being the most commonly used image modality. Therefore, it is essential to know the main surgical techniques, the expected postoperative findings and the optimization of imaging techniques for early diagnosis and correct evaluation of postoperative complications.

[Nodular alveolar pattern of presentation for amiodarone pulmonary toxicity]. / Patrón alveolar nodular como forma de presentación de la toxicidad pulmonar por amiodarona.

Amiodarone is a triiodinated antiarrhythmic drug that accumulates in alveolar macrophages. Its use is limited by its high rate of associated pulmonary toxicity, estimated at 5-7%. Radiologic findings for pulmonary toxicity caused by amiodarone are unspecific and varied. The most common finding is subpleural reticular-type interstitial thickening, predominately in the bases of the lungs. However, the presence of parenchymal nodules is an uncommon presentation. We report the case of a woman treated with amiodarone that presented multiple nodular lesions at plain-film radiography and high-resolution CT that were compatible with pulmonary toxicity caused by amiodarone at pathologic examination.

Patrón alveolar nodular como forma de presentación de la toxicidad pulmonar por amiodarona / Nodular alveolar pattern of presentation for amiodarone pulmonary toxicity

La amiodarona es un antiarrítmico triyodado que se deposita en los macrófagos alveolares, cuyo uso se ve limitado por su toxicidad pulmonar que presenta una incidencia estimada del 5-7%. Los hallazgos radiológicos de la toxicidad pulmonar por amiodarona son inespecíficos y variados, siendo el más frecuente un engrosamiento intersticial de tipo reticular subpleural de predominio en bases. La presencia de nódulos parenquimatosos es, sin embrago, una forma infrecuente de presentación de esta entidad. Exponemos el caso de una mujer en tratamiento con amiodarona que presentaba en la radiología simple de tórax y tomografía computarizada (TC) de alta resolución múltiples lesiones nodulares cuyo posterior estudio anatomopatológico confirmaba su compatibilidad con toxicidad pulmonar por amiodarona
