Diagnóstico incidental de tumor vesical por ecografía ginecológica transvaginal / Incidental findings of bladder tumor by transvaginal ultrasonography

Se presenta el caso clínico de una mujer de 60 años que acude al Servicio de Ginecología y Obstetricia del Hospital Padre Hurtado, bajo la sospecha de un mioma cervical pequeño. Se realiza una ecografía transva-ginal la cual evidencia incidentalmente un tumor vesical sólido, vascularizado, intravesical y dependiente de la mucosa. La paciente no refería espontáneamente hematuria. El estudio urológico definitivo es de un carcinoma papilar de células transicionales. El tratamiento endoscópico logró la resección completa del tumor. El hallazgo ecográfico permitió realizar el diagnóstico en una forma poco habitual para esta enfermedad, aprovechando una instancia definida para otros fines. Se rescata la importancia de observar detenidamente todas las estructuras pélvicas al alcance visual del equipo de ecografía.

We present a clinical case of a 60 year-old patient, who concurs to the Obstetrics and Gynecology Department of the Padre Hurtado Hospital under the suspect of a uterine-cervical myoma. A transvaginal ultrasonography was performed which incidentally revealed a bladder tumor which was solid, vascularized, clearly inside of the bladder and attached to the bladder mucosa. The definitive urological study was compatible with a transitional cells papillary carcinoma. The woman did not refer hematuria spontaneously. The finding allowed an unusual diagnosis in an ultrasound aimed for different purposes, which underlines the potential use of this method in other pelvic organs.

Intrathoracic pressure in congenital chylothorax: keystone for the rationale of thoracoamniotic shunting?

Thoracoamniotic shunting in fetal pleural effusion has poor results, with an overall survival of less than 50% when hydrops is associated. Those cases without hydrops presented the best evolution, but the indication in these cases remains controversial. We present a dichorionic diamniotic twin pregnancy at 29 weeks' with right pleural effusion and hydrops, in which one fetus presented diaphragm inversion and mediastinal shift, both considered as ultrasonographic signs of thoracic hypertension. A thoracoamniotic shunt reversed these signs immediately. Nevertheless, 1 week after, these signs and skin edema reappeared and the effusion increased, leading to a second thoracocenthesis for drainage and intrathoracic pressure measurement. Amniotic fluid and intrathoracic pressures were found at 21 and 39 mm Hg, respectively. A cesarean section was performed and the catheter was found to be obliterated by cellular detritus of leukocytes and fibrin. Our conclusion is that ultrasonographic signs of elevated thoracic pressure are a keystone for the shunt indication, and that this could be corroborated by direct measurements. This can be an important parameter for precise indication of thoracoamniotic shunting.
