Diagnosis of undifferentiated embryonal sarcoma of the liver-importance of combined studies of ultrasound and CT scan

Abstract

Undifferentiated embryonal sarcoma is the uncommon malignant mesenchymal tumor of the liver seen in children and young adults. Radiologic findings reflect the solid to cystic appearances observed in the gross specimens. The discrepancy in the appearances of the mass between the ultrasound scan and computed tomography scan is the hall mark of this tumor. Ultrasonography typically show a large mass which is hyperechoic or isoechoic (solid). Computed tomography shows cystic component of the tumor. This unique radiologic feature will help in the diagnosis of the tumour.
