Eight patients with malignant gestational trophoblastic disease had CT of the pelvis as part of their staging before chemotherapy. CT appearance of the uterus fell into three major types: normal size with irregular areas of hypodensity, uniform enlargement with areas of hypodensity, and focal areas of enlargement with or without areas of hypodensity. Patients with the second and third types were much more likely to have distant metastases and to require hysterectomy for successful treatment. CT findings of tumor nodules in the parametrium or myometrium were confirmed in three of the four surgical specimens of the uterus available for correlation. Myometrial tumor nodules were seen as areas of focal enlargement or as irregular eccentric areas of hypodensity. In one patient, parametrial extension was seen as an enhancing mass adjacent to the uterus. CT may be accurate in defining the extent of myometrial and adnexal disease and may have prognostic and therapeutic value.
8例恶性妊娠滋养细胞疾病患者在化疗前进行了盆腔CT检查作为分期的一部分。子宫的CT表现分为三种主要类型：大小正常但有不规则低密度区；均匀增大并有低密度区；局灶性增大，有或无低密度区。第二和第三种类型的患者更有可能发生远处转移，且为成功治疗需要行子宫切除术。在可用于对照的4份子宫手术标本中，有3份证实了子宫旁或肌层内肿瘤结节的CT表现。肌层肿瘤结节表现为局灶性增大区域或不规则偏心低密度区。1例患者子宫旁扩展表现为子宫旁强化肿块。CT在确定肌层和附件疾病范围方面可能是准确的，并且可能具有预后和治疗价值。
