uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...

Background : Cystic renal cell carcinoma has been reported to have a good prognosis. However, previous studies included cases of multilocular cystic renal cell carcinoma, which has an excellent prognosis, and renal cell carcinoma with cystic necrosis, which has an adverse prognosis. Therefore, we analyzed the prognostic influence of cystic change in clear cell renal cell carcinoma after excludi...

of patients with postprimary tuberculosis (1). However, cystic change associated with pulmonary tuberculosis has rarely been reported in radiologic and pathologic studies (2-4). According to these reports, cystic change developed before or during antituberculous chemotherapy in patients with pulmonary tuberculosis that initially presented with acute respiratory failure. Furthermore, these cysti...

Most pancreatic ductal adenocarcinomas (PDAs) show solid growth pattern, but ductal adenocarcinomas may demonstrate intratumoral cystic appearance or accompany peritumoral non-neoplastic cystic lesions, thus mimicking cystic pancreatic tumors on imaging studies. The histopathologic findings for PDA with cystic feature are divided into neoplastic and non-neoplastic cysts. Neoplastic cystic chang...

malignant germ cell tumors, and it most frequently occurs in the anterior mediastinum in the chest (1). The posterior mediastinum is a rare site of origin for seminoma, and prominent cystic change of a posterior mediastinal seminoma has not been previously described. The present report describes the CT, MR and F-FDG PET/CT findings of a case of a primary posterior mediastinal seminoma that was ...
