Despite of very high accuracy of USG by per patient analysis, the superior sensitivity of CT on the per level analysis may enable CT to play a complementary role for determining the surgical extent in selected patients with thyroid cancer.

A benign metastasizing leiomyoma is a rare condition that affects women with a history of a uterine leiomyoma. However, a benign metastasizing leiomyoma without a history of previous surgery has rarely been reported. Typical radiographic findings include well-circumscribed solitary or multiple pulmonary nodules ranging from a few millimeters to several centimeters in diameter and scattered among the normal interstitium. We report a case of abenign metastasizing leiomyoma that manifested with multiple cavitary nodules in a 46-yearold woman with no previous history of a myomectomy or hysterectomy.To the best of our knowledge, there has been only one case report of a benign metastasizing leiomyoma manifesting as cavitary lung nodules in the English language literature. Therefore, our case is noteworthy because multiple cavitary nodules are an unusual Computed Tomography (CT) finding of a benign metastasizing leiomyoma, and a benign metastasizing leiomyoma is very rare in a patient without a history of previous surgery. Case ReportA 46-year-old woman was referred to our hospital for evaluation of a uterine mass. On admission, abdominal and pelvic CT scans as well as preoperative chest radiography were performed. An abdominal and pelvic CT showed a 14 10 cm, multilobulating contoured uterine mass in the pelvic cavity (Fig. 1A). Based on the abdominal and pelvic CT scans, the radiological diagnosis was a uterine myoma. Chest radiography showed multiple, small nodules in both lungs and post-inflammatory sequela of pulmonary tuberculosis in both upper lobes A benign metastasizing leiomyoma is a rare condition that affects women with a history of uterine leiomyoma, usually after a myomectomy or hysterectomy. Typical radiographic findings include well-circumscribed solitary or multiple pulmonary nodules ranging from a few millimeters to several centimeters in diameter and scattered among the normal interstitium. We report a case of a benign metastasizing leiomyoma that manifested with multiple cavitary nodules in a 46-year-old woman with no previous history of a myomectomy or hysterectomy.
