Osteoblastomas are rare, benign bone tumors mainly arising from the long bones and the posterior vertebral arches. Skull localizations account for approximately 15% of cases. A total amount of thirty cases involving the temporal bone are reported in the literature. Clinical presentation of temporal osteoblastomas often includes local pain and swelling, while 7th and 8th cranial nerve impairment...

curs in the pediatric age group. Ohta et al. (1) defined this condition as “a collection of nonmuscular venous blood vessels or venous hemangiomas adhering tightly to the outer surface of the skull bone and directly communicating with an intracranial venous sinus by way of many diploic veins of several sizes.” To our knowledge, few reports published in Korea have described the MR imaging and MR...

creased dural venous sinus pressure or a defect in the arachnoid villi. The possibility of dural venous sinus thrombosis was ruled out in this case by MR examination that showed the venous sinuses to be widely patent. As suggested by the MR findings in this patient, low hemoglobin levels may result in compensatory changes in cerebral blood volume, leading to increased intracranial pressure. Thi...

1. Intracerebral hemorrhage can follow an asymptomatic interval after a trauma and may be due to local or systemic coagulation abnormalities, necrosis of blood vessels in areas of brain injury, transient cerebral dysautoregulation, reduction of intracranial pressure either medically or surgically, or cerebral venous sinus thrombosis. 2. Cerebral venous sinus thrombosis may be easily overlooked ...

Dural venous sinus thrombosis following a mild head injury is increasingly recognized. We report case of a 9-year-old male child presented with progressive headache and vomiting following a minor fall. A diagnosis of sinus venous thrombosis was suspected on nonenhancing computed tomography, and that was confirmed with magnetic resonance venography. The child was managed with intravenous fluids,...

We report on two patients with cerebral sinus venous thrombosis following chemotherapy with cisplatin, bleomycin and etoposide for non-seminomatous germ cell tumor. Headache and neurological deficits were the leading symptoms. Cancer and cisplatin chemotherapy are well-known risk factors for thromboembolic events. The therapeutic strategy is an anticoagulant therapy. Symptoms are usually revers...

ABSTRACTThe valves of right horn of systemic venous sinus are prominent structures within the right atrium during early embryonic period. Involution of these structures may not be complete, resulting in a spectrum of anatomical presentations such as cyanosis. A full-term male neonate referred to our hospital for precise evaluation of severe cyanosis on the first day of life. Echocardiographic e...

OBJECTIVE We would like to share our experience of surgical repair of sinus venosus atrial septal defect (ASD) using a simple "transcaval repair technique." METHOD Between January 2007 and October 2010, 48 consecutive patients of sinus venosus ASD underwent surgical repair using transcaval repair technique at our institute. Their ages ranged from 5 to 15 years and male to female ratio was 1.6...

Left hepatic vein (LHV) that drains blood into a coronary sinus (CS) is an extremely rare congenital anomaly of systemic vein drainage with only single reports published. In most of these cases the unusual venous connection was found incidentally during diagnostics or surgery. The case of a two-year-old boy in whom the anomaly was discovered during open heart surgery for partial anomalous pulmo...
