Hydatid disease is endemic in many parts of the world. It may develop in almost any part of the body. The location is mostly hepatic (75%) and pulmonary (15%), and only 10% occur in the rest of the body. In this article, the various imaging findings of hydatid cysts in unusual localizations are reviewed, based on our experience. Findings in brain, cavernous sinus, submandibular gland, thyroid gland, heart, pleura, chest wall, retrocrural tissue, kidney, spleen, pancreas, peritoneal cavity and inguinal canal, breast, bone and soft tissue are discussed.
Among the anthropometric factors to be considered, anatomic differences in the distal femur and intercondylar notch have been implicated as a cause of the different rates of anterior cruciate ligament (ACL) rupture between men and women; therefore, in this study our aim was to evaluate a number of morphometric measurements in the distal part of the femur. Two hundred knee MRI examinations were analyzed: 56 male right, 44 male left, 42 female right and 58 female left. Measurements of the intercondylar height (ICH), intercondylar width (ICW), medial condylar width (MCW), lateral condylar width (LCW) and epicondylar width (EW) were obtained. The notch shape index (NSI) was also calculated. Statistical analysis for comparisons was done by Student's t-test. Correlations between the parameters studied were calculated by Pearson correlation coefficients. Significant bilateral differences were not found (p > 0.05). In all measurements, males showed significantly greater values than females (p < 0.001). No difference was seen in the NSI between males and females (p > 0.05). Conversely a significant association was obtained between age and all parameters. We conclude that the results of this study may be useful for anatomic evaluation of the distal femur region prior to orthopaedic operations.

CT-marking and fluoroscopy-guided intraarticular corticosteroid instillation in the sacroiliac joints may be regarded as an effective therapy. This technique was useful, rapid and safe.
In detecting colon lesions, MRC achieved a diagnostic accuracy similar to CC. However, MRC is minimally invasive, with no need for sedation or analgesics during investigation. There is a lower percentage of perforation risk, and all colon segments can be evaluated due to multi-sectional imaging availability; intramural, extra-intestinal components of colonic lesions, metastasis and any additional lesions can be evaluated easily. MRC and CT colonography are new radiological techniques that promise to be highly sensitive in the detection of colorectal mass and inflammatory bowel lesions.
Elastofibroma dorsi is a rare benign and slow-growing fibro-proliferative lesion. It has a characteristic location (periscapular region) and a specific imaging appearance (sonography, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery. We report two cases of bilateral elastofibroma dorsi illustrating characteristic imaging features on ultrasound, CT and MRI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
