To investigate the value of color doppler ultrasound in the diagnosis of liver metastasis of gastrointestinal and extragastrointestinal malignant stromal tumors.
Methods:
The clinical data of 17 cases of gastrointestinal malignant stromal tumor and 3 cases of extragastrointestinal malignant stromal tumor with liver metastasis confirmed by pathology and immunohistochemistry from January 2015 to January 2020 in 904th Hospital of the Joint Service Support Force of the PLA were analyzed retrospectively
and the ultrasonic image c
haracteristics of the primary and intrahepatic metastasis of malignant stromal tumors were analyzed.
Results:
There were 24 primary tumors and 31 intrahepatic metastases in 17 cases
7 primary tumors and 9 intrahepatic metastases in 3 cases. Both primary lesions and intrahepatic metastases showed solid and cystic solid lesions
accounting for 83.1%. Most of the primary lesions (61.3%) showed blurred local edges
and some (41.9%) showed irregular morphology and shallow lobulation. Intrahepatic metastases showed clear boundaries (77.5%) and regular morphology (82.5%).
Conclusion:
Compared with the primary tumor of malignant stromal tumor
the cystic solid space with regular shape and clear boundary was the typical feature of the metastasis
it is of great clinical significance to judge the intrahepatic metastasis of stromal tumors.
