1/230. Successful treatment of obstructive sleep apnea with use of nasal continuous positive airway pressure in three patients with mucosal hemangiomas of the oral cavity.

    cysts and benign tumors are uncommon causes of obstructive sleep apnea (OSA), and surgical removal is usually favored. In patients in whom an operation poses a high risk, however, nasal continuous positive airway pressure (CPAP) may prove beneficial. We describe three patients with hemangiomas of the oral cavity in whom polysomnography revealed moderate to severe OSA. In all three patients, nasal CPAP effectively decreased sleep-related disordered breathing events and dramatically improved their sleep. To our knowledge, this is the first report of OSA associated with hemangiomas involving the upper airway. Our experience suggests that nasal CPAP therapy is effective and well tolerated in such patients.

2/230. Anterior approach to intramedullary hemangioblastoma: case report.

    OBJECTIVE AND IMPORTANCE: Intramedullary spinal cord tumors are generally operated on by using the posterior approach. However, the posterior approach may not be suitable for a tumor in the anterior part of the spinal cord. In this report, we describe a case of a cervical intramedullary tumor that was successfully removed by using the anterior approach. CLINICAL PRESENTATION: A 48-year-old woman presented with lower cranial nerve disturbance and motor weakness of the upper extremities. magnetic resonance imaging revealed a large extensive syrinx and an intramedullary enhanced tumor at the C6 level. The tumor was located at the left of the anterior part of the spinal cord. INTERVENTION: Based on these findings, the anterior approach was used in performing a corpectomy of C5 and C6. The tumor was highly vascular and was resected without resulting in any operative deficits. The pathological diagnosis was hemangioblastoma. CONCLUSION: The present case suggests that the anterior approach is an important option among surgical approaches to the intramedullary tumor in cases in which the tumors are small in size and are located in the anterior part of the cervical cord.

3/230. Complex right hemisphere developmental venous anomaly associated with multiple facial hemangiomas. Case report.

    Complex developmental venous anomalies (DVAs) represent variations of normal cerebral venous drainage and consist of dilation of the superficial and/or deep venous system. These rare anomalies can occur unilaterally or bilaterally, supratentorially or infratentorially, focally or they can affect the entire hemisphere. Some DVAs are associated with cervicofacial venous malformations or facial lymphatic malformations. Anomalies of this type are generally clinically silent, and cerebral dysfunction is usually absent. Symptoms, when they occur, are most commonly headache or mild seizure disorders. The angiographic findings are striking, with well-formed but enlarged transcerebral medullary and deep and/or superficial cortical veins. Opacification of these venous structures occurs within the same time frame as a normal angiographic venous phase. The authors report the case of a 33-year-old man in whom a large inoperable arteriovenous malformation had been previously diagnosed and who presented with seizures. Repeated magnetic resonance imaging and angiography demonstrated abnormally dilated transcerebral, superficial, and deep venous structures involving the entire right hemisphere with no identifiable nidus. Additionally, multiple bilateral benign facial hemangiomas were present in this patient. It is important to recognize this rare venous appearance as a developmental variant and not mistake it for an arteriovenous malformation or a partially thrombosed vein of Galen malformation. Because these venous anomalies are extreme variants of the normal venous system, hemorrhage rarely, if ever, occurs and the patient can be reassured that no interventional or surgical therapy is necessary or warranted.

4/230. A case of large placental chorioangioma with non-immunological hydrops fetalis.

    A 34-year-old Japanese woman (gravida 2, para 2) with polyhydramnios and non-immunological hydrops fetalis was referred to our department at 32 weeks of gestation. On admission, the blood pressure was 120/60 mmHg and there was no pitting edema of the lower extremities. An ultrasound examination disclosed a large placental tumor 5.8 cm x 4.4 cm x 4.8 cm. Fetal lung compression was suspected because the lung-thorax transverse area ratio was 0.13. The preload index of the inferior vena cava was 0.74, suggesting fetal cardiac failure. After fetal pleural effusion was aspirated, lung compression developed. cordocentesis was performed at 33 weeks of gestation, and the fetal karyotype was confirmed to be 46, XY from an umbilical blood cultivation. The patient underwent a cesarean section at 33 weeks of gestation due to severe uterine contraction after preterm PROM. The baby was a 3,840 g male with a distended abdomen. apgar score at 1 minute was 1. A chest X-ray demonstrated respiratory distress syndrome. The baby was discharged on the 69th day after birth and he is now 2 years and 9 months old and healthy.

5/230. Upper posterior mediastinal tumor supplied by an atrial branch of the left circumflex artery.

    We report a case of a 39-year-old woman with an upper posterior mediastinal tumor. The tumor was demonstrated by echocardiography and further defined by computerized tomography and magnetic resonance imaging. The tumor was fed by a large atrial branch of the left circumflex artery. Because of its location (adjacent to large vessels), it could not be resected by surgery.

6/230. Extraosseous extension of vertebral hemangioma, a rare cause of spinal cord compression.

    STUDY DESIGN: Case report. OBJECTIVE: To illustrate a rare cause of thoracic spinal cord compression, its diagnosis, and its management. SUMMARY OF BACKGROUND DATA: Asymptomatic vertebral hemangiomas are common, but extraosseous extension causing spinal cord compression with neurologic symptoms is rare, and few cases appear in the English-language literature. METHOD: A previously asymptomatic 63-year-old man sought medical attention for acute back pain and thoracic myelopathy of 6 week's duration. magnetic resonance imaging confirmed the presence of a mass in the T10 vertebral body with paravertebral and intracanalicular extension contributing to cord compression. decompression and reconstructive surgery were performed and radiotherapy administered after surgery. Preoperative angiography was not performed because of the patient's rapidly progressive neurologic deterioration and the consideration that the differential diagnosis of vertebral hemangioma was less likely. RESULTS: The diagnosis of benign capillary hemangioma was made histologically. Neurologic recovery was complete except for minor residual sensory changes in the legs. At follow-up 10 months after surgery the patient had returned to his usual active life and motor mower repairing business. CONCLUSION: Extraosseous extension of vertebral hemangiomas is a rare cause of thoracic spinal cord compression. As such, the available data are derived from reports based on series involving only a small number of cases, rather than on results of randomized controlled trials. Those causing progressive neurologic symptoms should be surgically decompressed, with the specific procedure determined by the extent and site of the lesion. Preoperative angiography is recommended, but embolization is not always necessary or even possible. Postoperative radiotherapy is recommended when tumor removal is subtotal.

7/230. Spindle cell hemangioma.

    A 27-year-old woman presented with multiple nodules closely grouped on her right upper distal extremity. The lesions, dating from childhood, increased slowly in time. Microscopic examination of one nodule showed the histologic features of spindle cell hemangioendothelioma (SCH). At the periphery of the nodule there were also some features of the so-called sinusoidal hemangioma. Clinically, SCH can present as a solitary lesion or as multiple lesions in zonal distribution. When the lesions are multiple, the diagnosis of Maffucci's syndrome should be considered. SCH may be interpreted as a reactive process secondary to thrombosis and recanalization occurring in angiomatous lesions with different clinical presentations. Spindle cells are probably mesenchymal cells modified by blood pressure. For this entity the term hemangioma seems to be preferable to that of hemangioendothelioma.

8/230. Estrogen and progesterone receptor-negative T11 vertebral hemangioma presenting as a postpartum compression fracture: case report and management.

    OBJECTIVE AND IMPORTANCE: pregnancy-related vertebral hemangioma compressive myelopathy is a rare occurrence that tends to arise in the upper thoracic and lower cervical spine, peaks during the third trimester, and remits after parturition. Whether corticosteroid receptors play a role in the pathogenesis of these lesions is unknown. Most of these lesions have been managed with posterior decompression. CLINICAL PRESENTATION: A 29-year-old woman presented with acute-onset lower-extremity weakness and sensory loss immediately after parturition. INTERVENTION: We used a retropleural approach for anterior decompression and fusion, followed by radiation therapy. Immunohistochemical analysis of estrogen and progesterone receptor expression was performed. CONCLUSION: We report an unusual case of lower thoracic postpartum vertebral hemangioma compressive myelopathy caused by a parturition-related compression fracture. Results of tests for corticosteroid receptors were negative, which implicated a hemodynamic rather than hormonal cause for disease progression.

9/230. Successful transcutaneous arterial embolization of a giant hemangioma associated with high-output cardiac failure and kasabach-merritt syndrome in a neonate: a case report.

    We describe the case of a patient with a neonatal giant cutaneous hemangioma with high-output cardiac failure and kasabach-merritt syndrome and successfully treated with transcutaneous arterial embolization aimed at controlling severe congestive heart failure and consumption coagulopathy. A patient was admitted to the neonatal care unit on the first day of age because of a large hemangioma on his right lateral chest wall and respiratory distress, associated with cardiac failure resulting from arteriovenous shunting. On the second day of age the platelet count decreased to 5.7 x 10(4)/microliter and fibrinogen level was 85 mg/dl. The values of prothrombin time and activated partial thromboplastin time were prolonged. Intravenous predonisone therapy was started immediately, but bleeding tendency was getting worse and the evidence of congestive heart failure persisted. On the third day the patient then underwent embolization of feeding arteries with microcoils. The cardiac failure and thrombocytopenic coagulopathy had improved significantly without complications. We conclude that transcutaneous arterial embolization is an effective and safe treatment in this neonate and should be considered for the treatment of control high-output cardiac failure and coagulopathy in infants with hemangioma and kasabach-merritt syndrome.

10/230. Bacillary angiomatosis affecting the oral cavity. Report of two cases and review.

    Bacillary angiomatosis (BA) is an infectious disease characterized by proliferative vascular lesions; it mainly affects hiv-positive patients. Multiple cutaneous nodular lesions together with fever, chills, malaise, anorexia, vomiting and headache are the most important clinical manifestations. It may also involve the heart, liver, spleen, bones, lung, muscles, lymph nodes, central nervous system and other organs. erythromycin, 500 mg four times a day, is the drug of choice. The importance of this lesion lies in its clinical and histological similarity with other diseases. Cutaneous and oral lesions of BA clinically resemble Kaposi's sarcoma (KS). Histopathologically, BA may be confused with angiosarcoma, pyogenic granuloma and epithelioid hemangioma. We report two hiv-positive men with BA lesions in the oral mucosa. diagnosis was confirmed by biopsy and Warthin-Starry silver staining.
