  • Lipoleiomyoma of the peritoneum
    Publication . Vasconcelos, C.; Cunha, Teresa Margarida; Félix, A.
    Lipoleiomyomas are rare, mixed mesenchymal tumors composed of adipose and smooth muscle cells. They usually arise from the uterus, with extrauterine tumors being extremely rare. The imaging and gross appearance is similar to other tumors with these constituents. Recognition of this rare and benign tumor is of great importance, in order to avoid erroneous diagnosis. We present a case of an extrauterine lipoleiomyoma with minimal amounts of fat, only identified by MRI. The extrauterine location was highlighted by multiplanar MRI, and the presence of a capsule suggested a benign tumor.

  • Preoperative assessment of deep myometrial and cervical invasion in endometrial carcinoma: comparison of magnetic resonance imaging and histopathologic evaluation
    Publication . Vasconcelos, C.; Félix, Ana; Cunha, Teresa Margarida
    This study aimed to evaluate the accuracy of magnetic resonance imaging (MRI) in the detection of deep myometrial invasion and cervical extension by endometrial carcinoma. This prospective study included 101 patients with histologically documented endometrial carcinoma, between July 1998 and April 2004. The findings of preoperative pelvic MRI were compared with histological diagnosis. From 101 cases studied by pelvic MRI, 43 were classified as deep myometrial invasion (50% of myometrium), where the pathological evaluation confirmed as having deep myometrial invasion. Cervical extension in the MRI study was found in 19 cases. Pathologic study found cervical extension and/or invasion in 31 cases including all cases identified by MRI. The accuracy, sensitivity and specificity of MRI were 95%, 89%, 100%, detecting deep myometrial invasion and 88%, 61%, 100%, detecting cervical invasion, respectively. The high accuracy achieved makes MRI an adequate method for determine the depth of myometrial and cervical invasion in endometrial carcinoma.
