Cardiac hydatid cysts are rarely seen. The presentation of an acute lower limb ischemia secondary to embolization from an interventricular hydatic cyst is also rare. We describe a case of a 30-year-old-man who presented with acute lower limb ischemia revealing hydatid cyst of the interventricular septum and septal defect, and who was operated on successfully.
Schwannomas (neurilemmomas) are benign tumors arising from the Schwann cells of the neural sheath. They are typically, well-encapsulated lesions which rarely adhere to the adjacent structures. In the chest, schwannomas are often seen within the posterior mediastinum and commonly originating along intercostal nerves. Several operative approaches have previously been described for the resection of these tumors, including thoracoscopic techniques and posterolateral thoracotomy. We report in this case a giant cystic mediastinal schwannoma of the left recurrent laryngeal nerve with cervical extension, unresectable by the usual described approaches, which was completely removed through a cervical approach.
A floating thrombus in the ascending aorta is rarely found in clinical practice and is an uncommon cause of peripheral arterial embolization. When there is minimal atherosclerosis or a normal aorta, the management of such a lesion is poorly defined. Currently, there is no clear consensus concerning optimal treatment. Herein, we report 2 cases of ascending aortic thrombus that are complicated by a peripheral embolic event. Due to the risk of recurrent systemic embolism, particularly with strokes, surgical thrombectomy with ascending aortic wall replacements was performed. We believe that floating ascending aorta thrombus represents a serious source of systemic embolism and stroke. Surgical removal is easy to perform with good clinical outcomes. Conservative treatments such as anticoagulation or thromboaspiration may be considered in high-risk or inoperable patients.
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.
