A 67-year-old male patient came to the hospital due to lung cancer and mediastinal cystic mass which was suspected to be esophageal duplication cyst. Video-assisted thoracoscopic surgery (VATS) was performed and intra-operative finding suggested it as a cystic mass along the thoracic duct. Thoracic duct was ligated and the cyst was completely resected. A 48-year-old female patient visited the h...

Primary pulmonary malignant fibrous histiocytoma (MFH) is a rare mesenchymal neoplasm of the lung. Myxoid variant is an uncommon subtype of primary pulmonary MFH. In this report we present a case of a young adult who had chest discomfort and was found to have a huge mass in the left lung. Left pneumonectomy was performed and a myxoid variant of primary pulmonary MFH was proven by immunohistoche...

We report 12 cases of renal cystic lesions that could not be diagnosed preoperatively. Sonography, computed tomography (CT), magnetic resonance (MR) imaging, and angiography were performed in all cases. Angiography was not helpful in evaluating cystic lesions, because all cystic lesions were hypovascular or avascular within the cystic mass. CT was useful in depicting the fine structural abnorma...

An MR examination in a patient with neurosarcoidosis showed an intrasellar cystic mass extending into the suprasellar space. The wall of the mass was thick, it enhanced after administration of contrast material, and it extended into the infundibulum and hypothalamus. Pathologic findings showed noncaseating granulomatous inflammation; the cystic component was considered to be ischemic necrosis o...

OBJECTIVE To evaluate the CT features of pathologically proven low grade serous carcinoma (LGSC) of the ovary. METHODS Patients with a pathologic diagnosis of LGSC and CT prior to oophorectomy were retrospectively identified. The CT scans in 14 patients were available and were analyzed for an adnexal mass, peritoneal mass and ascites. The adnexal mass was characterized as complex primarily cy...

Lymphangioma is a benign tumor, which is a consequence of lymphatic malformation with blockage of lymphatic flow. Most lymphangiomas occur in the neck and axillary region, and < 1% occur in the mesentery or retroperitoneum. Lymphangiomas arising from the pancreas are extremely rare. We report the case of a 34-year-old woman with cystic lymphangioma of the pancreas without major symptoms or sign...

Benign cystic peritoneal mesothelioma is a rare tumor which frequently occurs in women of reproductive age. Abdominal pain associated with pelvic or abdominal mass is the common clinical presentation. We report the case of a 22-year-old woman with a pathological proved benign cystic mesothelioma of the peritoneum revealed by a small bowel obstruction and a painful left-sided pelvic mass with si...

Chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. It is more common in older age and often affects the axial skeleton. We report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. A 40 yr woman presented with decreasing visual acuity and headache. Magnetic resonance (MR) image revealed a cystic sellar and suprasellar...

We report a five-month-old boy who was referred to the hospital with a presumptive diagnosis of hydrocele of the cord. Ultrasonography revealed a cystic mass within the left testis. A complete removal of the cystic mass was done. Histopathological diagnosis was simple cyst of the testis. This rare lesion should be considered in the differential diagnosis of cystic testicular lesions in infancy....

Background: Appendicovesical fistula in patients suffering from cystic fibrosis is a rare condition. Although this situation is so rare it should be considered in the differential diagnosis, dealing with a patient with cystic fibrosis and chronic abdominal pain with no response to primary management. To the best of our knowledge, this is the third case of appendicovesical fistula in a patient w...
