[Treatment of non-parasitic splenic cyst with percutaneous injection of alcohol]. / Tratamiento del quiste esplénico no parasitario con inyección percutánea de alcohol.

We report a case of a 12-years-old girl treated by percuta-neous injection of a splenic epithelial cyst. Indication was due to the gradual cyst's growth and pain in left hypocondrium. A percutaneous drainage under ultrasonographic view was performed with direct puncture technique, inserting a pigtail catheter into the cyst. After the total aspiration of the contrast, we injected sterile absolute alcohol for 20 minutes. Subsecuently, it was aspirated and the catheter was pulled-out. After a follow up period of more than 4 years, the cyst remains collapsed. There were no complications.

[Analysis of the Doppler signal (color and pulsed) in hepatocarcinoma]. / Análisis de la señal Doppler (color y pulsado) en el hepatocarcinoma.

Real time echocardiography associated with pulsed Doppler (duplex) and color (triplex) provide a non invasive technique to determine the vascular morphology of a lesion. The duplex and triplex signal of 35 liver tumors, 23 hepatocarcinomas and 12 angiomas found in the first high frequency signals greater than 1.81 kHz and traced with pulsatile or mixed morphology (pulsed and continuous) were analyzed. The second signals were of low frequency, less than 1 kHz and continuous tracing. It may be concluded than echo-Doppler is a complementary technique to conventional echography and is useful in the diagnosis of hepatocellular carcinoma.
