Subarticular cystic lesions often develop during the course of rheumatoid arthritis. They are considered to be one of the typical manifestations of the disease (Cruickshank, Macleod and Shearer 1954). Generally several small lesions are observed, showing a typical radiological and pathological picture (Steven 1947; Kersley, Ross, Fowles and Johnson 1964; Gardner 1965). Single giant bone cysts, ...

BACKGROUND Typical aneurysmal bone cysts (ABCs) are osteolytic, multicystic lesions with parietal sclerosis and blood-filled cysts. In rare instances, the cystic components may be completely absent. Such solid variants in ABC (s-ABC) exhibit a solid architecture; making the clinical, radiological, and histological differentiation from other solid bone tumors like osteosarcoma (especially giant ...

PURPOSE Brain metastasis (BM) with a cystic component from breast cancer is rare and largely uncharacterized. The purpose of this study was to identify the characteristics of cystic BM in a large cohort of breast cancer patients. RESULTS A total of 35 eligible patients with cystic BM and 255 patients with solid BM were analyzed. Three factors were significantly associated with an increased pr...

Cystic hypersecretory lesions of the breast are rare. These breast lesions include cystic hypersecretory hyperplasia (CHH), atypical CHH, and cystic hypersecretory carcinoma (CHC). The characteristic features are dilated ducts and cysts filled with thyroid colloid-like eosinophilic secretion. Only seven cases of invasive CHC have been reported in the literature. Here, we report an additional ca...

congenital cystic lesions of the pancreas are rare findings. furthermore, dermoid cyst of the pancreas is exceptionally uncommon. a review of the world literature showed that only 18 documented cases of dermoid cyst of the pancreas were reported so far. the pre-operative evaluation of this lesion is rather questionable, with definitive diagnosis taking place intra-operatively. herein, we presen...

Endoscopic ultrasound (EUS) allows high resolution imaging of the pancreas. EUS is a very useful technique for evaluating morphological features of a cystic tumors of the pancreas. These features include thick wall type, tumor protruding type, thick septal type, microcystic type, thin septal type and simple type. Malignant cystic lesions may present as a hypoechoic cystic/solid mass or as a com...

BACKGROUND AND PURPOSE T1-, T2-, and proton density (PD)-weighted sequences are used to characterize the content of cystic intracranial lesions. Fluid-attenuated inversion recovery (FLAIR) MR sequences produce T2-weighted images with water signal saturation. Therefore, we attempted to verify whether FLAIR, as compared with conventional techniques, improves the distinction between intracranial c...

CONTEXT Pancreatic cystic lesions are increasingly recognized and comprise different pathological entities. The management of these lesions is challenging, because of inadequate preoperative histological diagnosis. Among this family of lesions, mature cystic teratomas are an extremely rare finding. CASE REPORT We present the case of a 61-year-old man with a mature cystic teratoma of the pancr...

conclusions our data provided information on the prevalence and types of intraosseous lesions among an iranian population. this study provided baseline information to help in designing and programming procedures in health care centers in every community so that preventive therapeutic measures can be adopted. patients and methods this cross-sectional descriptive analytical study was carried out ...
