T o our knowledge, there has been only one previous histologically confirmed report of an intraventricular cavernous hemangioma in a newborn baby. 17 Voigt and Yaşargil 33 reported a review of 164 cases of cavernous hemangiomas, four (2.5%) of which were intraventricular in origin. We have treated the case of a newborn girl who was found to be hydrocephalic at birth and in whom computerized tomography (CT) scans revealed a mass in the lateral ventricle. Cavernous hemangioma was the histological diagnosis. On the 8th day after her birth, we removed the

thrombi. In some areas, the interstitial connective tissue contained small capillaries with prominent endothelial nuclei. These findings were diagnostic for a cavernous hemangioma. The compressed pituitary tissue showed a normal cellular composition with evidence of interstitial hyalinization caused by atrophy. A portion of the displaced left oculomotor nerve was incorporated into the fibrous capsule. The histological structure of this nerve appeared to be normal. Fig. 1.

V ery rare lesions that occur in the sellar region should be considered when resecting pituitary adenomas. 3 We present the case of a patient who was being observed using MR images because he harbored a benign hemangioma of the orbit. The patient was found to have an expanding, contrast-enhancing lesion in the sella turcica that was thought to be a nonfunctional pituitary macroadenoma. During surgery, a highly vascular lesion was encountered that was adherent to the dura of the cavernous sinus. The pathological diagnosis was cavernous hemangioma. Case

Spinal epidural cavernous hemangiomas

Report of three cases and review of the literature

. Cavernomas affecting the spine are seen most frequently in the vertebral bodies. Intramedullary and intradural—extramedullary lesions of the spinal axis are uncommon, and purely epidural lesions are very rare. 15 To our knowledge, only 10 cases based on MR studies have been reported. 5, 6, 11, 12, 14, 15, 18 In those cases, the usual clinical manifestation was an acute spinal cord syndrome. Cavernous hemangiomas causing chronic radiculopathy have seldom been reported. 15 We report on two cases of thoracic epidural cavernous hemangiomas, one with intra- and

I ntracranial cavernous hemangiomas are relatively rare lesions which represent 5% to 13% of central nervous system vascular malformations. 3, 10 These lesions most commonly involve the cerebral hemispheres, particularly the parietal lobe and basal ganglia. 7 Intracranial extracerebral cavernous hemangiomas are particularly unusual. These malformations arise most often from the middle fossa and tend to involve extensively structures within the cavernous sinus. 4, 5 A case of an extra-axial cavernous hemangioma located within Meckel's cave which involved the

C avernous hemangiomas are uncommon vascular malformations that may involve any part of the central nervous system but are rare in the cavernous sinus region. 12, 40 Many cases are clinically occult and are found only at autopsy, whereas others may present in the third to sixth decades of life with seizures, headaches, hemorrhage, or neurological deficits. When completely resected they are surgically curable; however, because the surgical approaches to the cavernous sinus are complicated by the complex neurovascular relationships, cavernous hemangiomas in

C avernous hemangioma is frequently cited as the most common primary orbital tumor; 3, 9, 11 yet, to our knowledge, an extensive study devoted exclusively to many of these cases has not been reported. The present study, consisting of 66 cases of orbital cavernous hemangioma, was undertaken to answer a number of important clinical and histological questions that have persisted with respect to this tumor: 1) what is its clinicopathological relationship, if any, to capillary hemangioma of childhood; 2) which clinical features are distinctive to this tumor and

I n recent years, intracranial cavernous hemangiomas have been detected more frequently by means of computerized tomography (CT). 8, 9 Although many of these lesions have been reported in intracerebral or extradural locations, a cavernous hemangioma arising in the optic nerve and chiasm is very rare. To our knowledge only two such cases have been reported previously at this location. 2, 3 An additional case with a cavernous hemangioma of the optic nerve is reported; the lesion led to visual impairment of subacute onset after the patient was delivered of a

T he theoretical goal of radiosurgery for cavernous hemangiomas is to obliterate the lesion and thereby to prevent its rebleeding; however, direct proof of the postradiosurgical obliteration of these lesions is not available and the process of evaluating the results of radiosurgery is in not simple. There are difficulties in actually defining what constitutes cavernous hemangioma bleeding, as well as in establishing its correct diagnosis. Usually any sudden onset of new symptoms or exacerbation of the old ones is considered a hemorrhage, despite the lack of
