A renal mass accompanied by adenopathy was found incidentally in an asymptomatic 25-year-old woman. The computed tomography and ultrasonography findings suggested a malignant neoplasm. At pathological examination, however, renal angiomyolipoma was diagnosed; the lesion contained almost no fat and involved the lymph nodes, an unusual presentation for this tumour.

PURPOSE: To determine the prevalence of decidual cysts in patients with ectopic pregnancy and assess the value of endovaginal sonographic demonstration of decidual cysts in predicting ectopic pregnancy. MATERIALS AND METHODS: A series of 288 proved ectopic pregnancies was reviewed, and a series of 179 patients with pregnancies of less than 8 weeks menstrual age was prospectively examined. RESULTS: Decidual cysts were identified in 30 (14.4%) of 208 ectopic pregnancies. In 12 patients a decidual cyst was the first sonographic sign of ectopic pregnancy, and in six patients it was the only abnormal sonographic finding. Four of five patients with decidual cysts had an ectopic pregnancy. Decidual cysts had a sensitivity of 21%, specificity of 92%, positive predictive value of 80%, and negative predictive value of 42% in the diagnosis of ectopic pregnancy. CONCLUSION: Patients with decidual cysts are at high risk for ectopic pregnancy and should be monitored or treated appropriately, depending on the clinical findings.

PURPOSE: To evaluate the relationship of the endometrial canal and decidua vera to the interstitial gestational sac and to determine if this relationship can be used to increase the predictive value of ultrasound (US) in the diagnosis of interstitial ectopic pregnancy. MATERIALS AND METHODS: The US findings in 12 patients with interstitial ectopic pregnancy were reviewed. Radiologists also reviewed the cases of 40 patients with various diagnoses to assess the accuracy of the interstitial line sign. RESULTS: US showed a definite gestational sac in four of the 12 patients (33%); the rest had a heterogeneous mass in the cornual region. Thinning of the myometrial mantle was seen in these four patients. The gestational sac appeared eccentric in three of these but in only three of 12 (25%) overall. The endometrial canal or interstitial portion of the tube was identified in 11 of 12 patients (92%). The interstitial line had better sensitivity (80%) and specificity (98%) than eccentric gestational sac location (sensitivity, 40%; specificity, 88%) and myometrial thinning (sensitivity, 40%; specificity, 93%) for the diagnosis of interstitial ectopic pregnancy. CONCLUSION: The interstitial line sign is a useful diagnostic sign of interstitial ectopic pregnancy.
