Abstract:
Objective To investigate the CT features and the diagnostic value in invasive mole. Methods Eleven cases (age, 30 to 53 years, mean 40 years)with invasive mole proved by operation and pathology were studied, including 3 cases during peri menopausal period of eight months, ten months and twelve months respectively. All cases were scanned by CT and enhanced study was done. Results All cases showed enlargement of uterus of varying degrees. On CT, the density of uterine cavity was similar to that of water, intermingled with spotty patchy and hazzy circular isodense shadows. High density stripe like bleeding foci were found in 3 cases.The outline of uterine cavity was locally disrupted in all case and the muscle layer was thickened in 3 cases. On enhanced CT scan, the lesions in the uterine cavity appeared markedly hyperdense, just like “the crater” and the “mole sign” .The muscle layers at the site of disruption showed inhomogeneous enhancement after contrast injection. Conclusion The CT features of invasive mole are characteristic, with important diagnostic value, especially for those during peri menopausal period.
