Imaging revealed a large intraabdominal mass in the epigastrium. Despite intensive investigations, including ultrasound scanning, computed tomography, upper gastrointestinal endoscopy, and percutaneous biopsy, a diagnosis could not be obtained. A histological diagnosis of cavernous hemangioma arising from the gastro-splenic ligament was confirmed after laparoscopic excision and histological examination of the intra-abdominal epigastric mass.展开更多

METHODS: A total of 5783 candidates for routine analysis were evaluated for hepatic vascular abnormalities by ultrasonography. RESULTS: Ten candidates (0.17%) had a portal vein anomaly with a rightward-deviated ligamentum tere. The blood-flow velocity in the PRUV of the portal vein (17.7±3.0 cm/s) of the 10 cases was similar to that of the right anterior portal trunk (17.6±4.1 cm/s). However, the vessel diameter of the PRUV (φ12.4±4.4 mm) was larger than the right anterior portal trunk (φ6.1?.9 mm). Therefore, flow volume in the anomalous portion (0.97±0.30 L/min) was more than that in the right anterior portal trunk (0.18±0.05 L/min). CONCLUSION: The anomaly plays an important role in intra-hepatic PV flow.展开更多

In patients with this condition, the absence of a vertebral fracture or a major vascular injury is extremely rare. We present the case of a 92-year-old man who hit his forehead by slipping on the floor in his house. He had no symptoms at the time; however, he experienced throat pain and dyspnea at 6 hours after the injury. On arrival, he complained of severe dyspnea; therefore, an emergency endotracheal intubation was performed. A lateral neck roentgenogram after intubation showed dilatation of the retropharyngeal and retrotracheal space and no evidence of a cervical vertebral fracture. Cervical computed tomography (CT) with contrast medium revealed a massive hematoma extending from the retropharyngeal to the superior mediastinal space but no evidence of contrast medium extravasation or a vertebral fracture. However, sagittal magnetic resonance imaging (MRI) revealed an anterior longitudinal ligament (C4-5 levels) injury. We determined that the cause of the hematoma was an anterior longitudinal ligament injury and a minor vascular injury around the injured ligament. Therefore, we recommend that patients with retropharyngeal hematoma undergo sagittal cervical MRI when roentgenography and CT reveal no evidenee of injury.展开更多
