Uterine lipoleiomyomas are rare variants of leiomyomas that usually occur in postmenopausal women. Their incidence ranges from 0.03% to 0.2%. Few cases of laparoscopically resected lipoleiomyomas have been reported in the literature.Further accumulation of lipoleiomyomas could help establish an accurate preoperative diagnosis of this uncommon and benign mesenchymal tumor.
parapharyngeal, and esophageal biopsies. Also included will be examples of biopsies of masses that extend into the adjacent superior mediastinum. The various approaches to lesions in these difficult to reach locations will be reviewed. The use of color Doppler and optimal patient positioning will be highlighted.Results: Procedures can be performed with ultrasound alone or as a combined procedure using both CT and ultrasound. A benefit of the combined CT-ultrasound procedure is that ultrasound decreases the time needed to reach the lesion with an off axial approach as well as decreases the radiation dose. The CT can then verify needle position within the lesion.Conclusions: Ultrasound-guided biopsies can be performed safely and efficiently in the deep spaces of the head and neck. Using the techniques described in this presentation, lesions that are seemingly inaccessible can be biopsied with ultrasound guidance. Ultrasound provides numerous advantages over CT in terms of lower cost, no radiation exposure, and multiplanar approach.
Algorithm for Skeletal Dysplasias by Prenatal Ultrasound: Emphasis on Predicting Lethality Kathryn Milks, Keyanoosh Hosseinzadeh Radiology, Wake Forest Baptist Medical Center, Winston Salem, NC, United StatesObjectives: We describe a simplified algorithm for determining lethality of a suspected skeletal dysplasia by prenatal ultrasound.Goals Understand when to consider the diagnosis of a skeletal dysplasia Recognize accurate predictors that constitute a lethal skeletal dysplasiaRecognize sonographic features of the major lethal skeletal dysplasias and the unique features that distinguish one from another Methods: A literature review of all predictors of lethality in skeletal dysplasias was performed. The most reliable predictors of lethality were determined using relative sensitivity, specificity, negative predictive value, and positive predictive value. We combined the most reliable predictors of lethality to create an original, logical, and simple algorithm to accurately determine those skeletal dysplasias that are incompatible with life.
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.
