1/17. association of venous angioma and atypical meningioma--case report.

    A 67-year-old male presented with an atypical meningioma arising from the right tentorium associated with a venous angioma in the left cerebellar hemisphere. The venous angioma was detected incidentally during examinations for the brain tumor. The brain tumor was removed completely and the venous angioma followed conservatively. Venous angiomas associated with brain tumors should be followed conservatively, as the clinical significance and surgical indications are unclear. ( info)

2/17. Cerebral venous infarction following thrombosis of the draining vein of a venous angioma (developmental abnormality).

    We report two cases of cerebral venous angioma presenting as venous infarction, one in the left parietal lobe, the other in the left frontal lobe. Cerebral imaging demonstrated thrombotic occlusion of the draining vein of the venous angioma associated in the latter case with thrombosis of the anterior part of the superior longitudinal sinus. Both patients were free of coagulopathy. They were treated with anticoagulant therapy. One completely recovered, while the other was left with slight residual disability. thrombosis of the draining vein has been reported in only 6 previous cases, of whom only 2 received anticoagulant therapy. Discovery of a venous angioma in the diagnostic workup of a patient with recent neurological disorders should raise the question of a possible occlusion of the draining vein and lead to an appropriate therapy.

3/17. Diffuse neonatal haemangiomatosis.

    A newborn girl with severe diffuse neonatal haemangiomatosis is described. She was treated with high dose systemic corticosteroids and high dose interferon-alpha-2a, but with fatal outcome. A review of the current literature is presented. ( info)

4/17. Cerebral hemiatrophy caused by multiple developmental venous anomalies involving nearly the entire cerebral hemisphere.

    The authors present a case of multiple developmental venous anomalies (DVAs) that involved nearly the entire cerebral hemisphere and that were diagnosed by magnetic resonance (MR) imaging and selective cerebral angiography. The ipsilateral cerebral hemisphere was mildly atrophic, and there were focal white matter lesions on the MR images. Angiography showed multiple DVAs involving nearly the entire right cerebral hemisphere. We suggest that longstanding venous congestion caused the atrophy and white matter lesions. ( info)

5/17. Midbrain venous angioma with obstructive hydrocephalus.

    A rare case of a mid brain venous angioma with obstructive hydrocephalus is described. A dilated draining vein from the lesion in the aqueduct as the cause of the hydrocephalus is highlighted, and interesting features of the pathology of venous angiomas and associated cavernous hemangioma are described. The management of this interesting condition is discussed. ( info)

6/17. Successful ECT in a patient with intracranial venous angioma.

    The 1990 American Psychiatric association (APA) Task Force report on electroconvulsive therapy (ECT) suggests that there is an increased risk of complications in patients with intracranial vascular masses. There have been only a few published reports on the use of ECT in these patients. In this case report, an additional case is described that used ECT in the treatment of major depression in a 72-year-old patient with a venous angioma involving the left cerebellum. brain imaging studies, neurosurgery, cardiology, and orthopedic consultations were obtained prior to ECT. blood pressure was monitored closely throughout the course of ECT. Prior to each ECT, antihypertensive medication was given in addition to other pretreatment medications. Consistent with previously published reports, the patient did not experience any neurological deterioration or adverse effects. A brief review of the literature on the use of ECT in patients with venous angioma and other intracranial vascular masses is presented. ( info)

7/17. third ventricle cavernoma associated with venous angioma. Case report and review of the literature.

    A case of third ventricle cavernous angioma associated with venous angioma is reported. By a transventricular approach, the cavernoma was totally removed with successful preservation of the venous malformation. After review of the literature, the clinical characteristics and the surgical approach to third ventricle cavernous angioma are discussed; the importance of preservation of associated venous angioma is also underlined.

8/17. Recurrent cryptic vascular malformation associated with a developmental venous anomaly.

    Abnormal venous drainage patterns, such as developmental venous anomalies (DVAs), are frequent findings neighbouring cryptic vascular malformations (CVMs). Although the clinical relevance of DVAs remains controversial, increasing attention has been focused on the possible importance of venous outflow disturbance and venous hypertension in DVAs for the development of CVMs. We present the case of a 32-year-old man with dysphasic seizures symptomatic for recurrence and rebleeding of a CVM of the left angulare gyrus, which drained entirely into a large DVA. A cavernoma had been surgically removed 1 year before, while the associated DVA had been left in place. In the following second surgical procedure, the new malformation, which was histologically verified as arteriovenous angioma (AVM), was removed and the DVA was occluded for the length of the angioma. Postoperative course of the patient was unremarkable, the patient is seizure free and neurologically intact. This first report of such a sequence of events raises important questions regarding the association of various vascular malformations, regarding transitional and hybrid forms, as well as the role of anomalous venous drainage in their pathophysiology and probably in their development. Our case and selected cases in literature suggest that venous hypertension in a DVA might not be just a coincidential finding, but sometimes can induce or influence the development and recurrence of associated vascular lesions. The developmental interrelationship, the potential mechanisms for this association and the implications of similar cases reported in pertinent literature are discussed. ( info)

9/17. A case of venous angioma with arteriovenous shunts--case report.

    A 35-year-old man presented with a sudden headache and disturbance of consciousness. On admission, his consciousness level was japan coma Scale 100. Computed tomography disclosed a subarachnoid hemorrhage (SAH) and right cerebellar hematoma. Angiography was performed and, at first, arteriovenous malformation of the posterior fossa was diagnosed. Then external decompression of the posterior fossa and ventricular drainage were performed, followed by barbiturate therapy. Repeat angiography revealed that the lesion was a venous angioma with arteriovenous shunts. On day 37, subtotal removal of the lesion was performed. Intraoperatively, acute brain swelling emerged and partial internal decompression of the right cerebellar hemisphere was performed. The postoperative course was comparatively good and the patient was discharged with very mild ataxia. The patient is now being followed up in our outpatient clinic. ( info)

10/17. Venous angioma associated with atypical ophthalmoplegic migraine.

    BACKGROUND: ophthalmoplegic migraine is a rare syndrome in which episodic headaches are associated with ophthalmoplegia. Several recent reports emphasize the possibility, especially in atypical cases, of a heterogeneous type of ophthalmoplegic migraine. methods: We describe the case of an 18-year-old woman with recurrent episodic headache accompanied by binocular diplopia due to left third cranial nerve palsy. The symptoms resolve in hours. A diagnosis of atypical ophthalmoplegic migraine was established. RESULTS: Digital angiography revealed a venous angioma draining into the left cavernous sinus. CONCLUSIONS: This case reveals the importance of differential diagnosis in atypical migraine in which the symptomatology could be secondary to intracranial lesions. We propose venous stasis as a cause of symptoms. ( info)
