Ultrasound estimation in kidney and parotid tumoral pathology association

The ultrasound can emphasize some pathological aspects which can be into a pathogenetic or association relationship.

Aim: Presentation of echographic imagery in a case with double, kidney and parotid tumor determination.

Patients and method: We are describing a female case, 71 years old to which ultrasound detected a kidney tumor and a both parotid glands tumor with cervical adenopathy. Pathological exam described tumor cells.

Results: The ultrasound description of a unilateral tumoral kidney formation of large dimensions (8/6cm) relatively well delimited with an non homogenous tissue aspect with mass effect associated with moderate splenomegaly (14/8cm) with the hunch backing of the left hemidiaphragm without any other local regional or hepatic or contralateral kidney, retroperitoneal, ganglionar or pleural modifications, with local slow evolution during 4 years. After 3 years the growth of the contralateral parotid gland appears, ultrasound being observed a non homogenous aspect with irregular outline with hypo and non-echogenic areas through intratumoral necrosis and under echographic guidance the biopsy has shown atypical cells associated with ganglionary modifications. After a year the swelling of the other parotid gland appears, the ultrasound finds also a tumor.

Conclusions:

1. The ultrasound oriented to a unilateral kidney formation and also to a bilateral parotid and cervical ganglionar one.

2. The two tumor can be estimated as metastasis (rarely seen in kidney and parotid tumor, especially the contra lateral one) or as an association of two neoplasias, also rare.

3. The ultrasound estimates the tumor as evolution involvement or as particular association.
