PURPOSE MR assessments of ovarian cystic lesions are usually based on morphological features, signal intensities and enhancement with contrast media. This study was performed to evaluate the usefulness of the steady-state free precession (SSFP) diffusion imaging of cystic ovarian lesions for analyzing cystic contents. MATERIALS AND METHODS Sixty-one ovarian cystic lesions in 37 patients were ...

Proton MR spectroscopy (PMRS) has been found to be useful in differentiating various cystic intracranial lesions. The purpose of the present study was to prospectively evaluate the spectral pattern of various cystic lesions of brain with similar imaging appearances and to determine the accuracy of this technique in the differential diagnosis of these lesions. Fifty-one patients with intracrania...

Hydatid cysts can be caused by Echinococcus species in various tissues. Skeletal cystic lesions are very rare and may be neglected. Here, we report a case of pathologic fracture following primary hydatid cystic lesions in the proximal and femoral shaft bone. A 62-year-old man suffered a sudden fracture followed by swelling of the thigh. Intramedullary femoral fixation was made and during the su...

Bronchogenic cysts in the muscularis of cardia are very rare lesions. We report a 33-year-old woman who presented epigastric distention, pain, nausea and vomiting. MRI diagnosis lesion was stromal tumor located liver stomach space. Ultrasonic examination indicated that cystic structure closely related to gastric wall, lesions from wall were determined.

introduction: a hydatid cyst of the head and neck is a very rare condition, even in areas where echinococcus infestation is endemic.   case report: we report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. the initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (ct) scan. we resected the cystic ...

Objective. Classification diagnosis was performed for cystic pancreatic lesions using ultrasound (US) and contrast-enhanced ultrasound (CEUS) to explore the diagnostic value of CEUS by comparison with enhanced CT. Methods. Sixty-four cases with cystic pancreatic lesions were included in this study. The cystic lesions of pancreas were classified into four types by US, CEUS, and CT: type I uniloc...

Introduction: Neuroendocrine tumors(NET) represent rare neoplasms with majority primary NETs being gastroenteropancreatic or bronchopulmonary origin. A hepatic NET is most likely a metastastic lesion. Cystic lesions are commonly either infectious, benign cystic lesions, if malignant; cystadenocarcinoma, hepatocellular carcinoma, metastasis degeneration. Primary neuroendocrine tumors(PHNETs) and...
