[An ultrasonographic picture of a growing pseudotumor in the abdominal cavity].

The case history of patient is presented who was diagnosed a tumor in abdominal cavity in an ultrasonographic examination. In the following surgery the tumour was extirpated and histology verified a liposarcoma. The control ultrasonographic examination revealed a growing solid formation in the region of resection. For presumed relapse of liposarcoma the patient underwent laparotomy again. In the region of the original tumour there was a conglomerate of adhesions in a size of tangerine. The histological examination revealed fibrous and fatty tissue without the sign of malignity.
