Intracerebral Hemorrhage Caused by Thrombosis of a Developmental Venous Anomaly with an Unusual Structure: A Case Report.

Developmental venous anomalies (DVAs) are common intracranial vascular malformations and they are generally do not cause clinical complications. In cases showing DVA and hemorrhage, the hemorrhage is usually associated with adjacent cavernous malformations. Very few cases of intracerebral hemorrhage (ICH) caused by thrombosis in DVA have been reported in the literature. In this case report, we present an interesting case of a large ICH caused by thrombosis within a DVA with an unusual structure that may have potentiated the thrombosis.

Macrocystic lymphatic malformation of the chest wall and axilla: A case report in a 45-year-old man.

Lymphatic malformations (LMs) are rare, with more than 90% occurring during childhood. Most LMs are located in the head, neck and axilla. LMs in chest wall are extremely rare, particularly in adults. This report describes a 45-year-old man with a large macrocystic LM in the right anterior chest wall. Computed tomography showed a ∼15 cm sized, well-defined, homogeneous and hypoattenuated mass without enhancement in the right anterior chest wall. On ultrasonography (US), the mass was circumscribed and anechoic, with internal septations and posterior acoustic enhancement. Following surgical excision, the mass was diagnosed as a macrocystic LM.

Transcatheter Removal of Bone Cement Embolism in the Right Atrium after Percutaneous Vertebroplasty: The Embolus Broke in Half and Migrated to the Right Pulmonary Artery Intraoperatively.

Bone cement embolism often occurs during percutaneous vertebroplasty. Bone cement pulmonary arterial embolism generally requires no treatment because of the small size and asymptomatic manifestation. Intracardiac bone cement embolisms are rare but associated with a risk of severe complications. Intracardiac bone cement embolisms are mainly removed through open heart surgery. To the best of our knowledge, only three cases of intracardiac bone cement embolisms removed with interventions have been reported. Here, we report another case of successful transcatheter retrieval of a 6-cm-long cement embolism in the right atrium after percutaneous vertebroplasty. The embolus broke in half and migrated to the right pulmonary artery intraoperatively. Using two snares and a filter retrieval device, we advanced from opposite directions. Further, we gently grasped and pulled the fragments of the right pulmonary artery and aligned them in a linear fashion directly into the sheath for uneventful removal.
