Spanish term (edited): parapi�lico

Hi chamito,

I think it's better to await confirmation from a specialist, but this is what I found as the more commonly accepted names in English. The pyelos is the renal pelvis. Below is the definition of a parapelvic cyst:

Cyst, parapelvic,
(also called renal sinus cyst, pelvic cyst, peripelvic cyst or parapelvic lymphangiectasia), are found at 12% of autopsies. Patients are usually in their fifth or sixth decades and are almost always asymptomatic. There are rare instances of obstruction of a collecting system. Pathogenesis is not established; however, lymphatic ectasia is proposed, possibly secondary to lymphatic obstruction. Sonography will show multiple echo-free areas in the region of the renal sinus. Differentiation from hydronephrosis may be difficult and renal sinus cysts are one of the most common causes of a false positive diagnosis of hydronephrosis on ultrasound. A diagnosis of hydronephrosis is established without question when dilated calyces are seen to communicate with a dilated renal pelvis. On CT (Fig.1) renal sinus cysts have the attenuation value of water. On non-enhanced scans multiple renal sinus cysts resemble a dilated renal pelvis and thus mimic hydronephrosis. On contrast-enhanced scans and on intravenous urography, the nondilated inundibulae and pelvis will be stretched and compressed by and curve between multiple renal sinus cysts. Differential considerations include renal sinus lipomatosis (fat density), lymphoma, haemorrhage and urinoma.

As I say, better await confirmation that we are speaking of the same thing.

Good luck!

pel·vis (pĕl\'vĭs)
n., pl. -vis·es or -ves (-vçz).

1. A basin-shaped structure of the vertebrate skeleton, composed of the innominate bones on the sides, the pubis in front, and the sacrum and coccyx behind, that rests on the lower limbs and supports the spinal column.
The cavity formed by this structure.

****2. The hollow funnel in the outlet of the kidney, into which urine is discharged before entering the ureter. Also called renal pelvis.****
[Latin pçlvis, basin.]

Too late for points, but this is a no-brainer, when you see how many hits there are, and take into account that "peri-" and "para-" are used interchangeably, varying depending upon the specific term.
