Fronto-ethmoidal and orbital osteomas with intracranial extension. Report of two cases.
No full textOsteomas involving the anterior cranial base are quite rare lesions. Intracranial and orbital extension of these tumors, causing neurological and ophthalmological symptoms and signs is a rare event. Two such cases are reported. In the first one, the tumor arose from the frontal sinus and extended upward to the medial and superior wall of the right orbital cavity and the lower part of the right frontal convexity. In the second case the osteoma arose from the left orbital roof and extended to the lower part of the homolateral frontal convexity and the splenoid wing. After the operation the symptoms disappeared and the cosmetic deficits were corrected. Skull-films, CT and MR well define the bony extension and the displacement of the orbital and intracranial structures. Indications to the surgery include progressive ophthalmologic and neurologic signs and significant cosmetic deformations. The surgical techniques and the postoperative complications are briefly discussed
Spontaneous cure of a ruptured intracranial aneurysm.
No full textA rare case of spontaneous cure of an internal carotid artery aneurysm is reported; the progressive resolution of the spasm and the disappearance of the aneurysm have been confirmed by serial angiograms respectively performed two weeks, two months and four months after the hemorrhage. The other 14 reported cases of angiographically documented spontaneous cure of intracranial aneurysms are reviewed and the possible causes of spontaneous aneurysmal thrombosis, such as retarded cerebral circulation, arterial spasm, size of the neck, thrombosis of the feeding artery and antifibrinolytic therapy, are discussed
Cerebral gliosarcomas: correlation of computed tomographic findings, surgical aspect, pathological features, and prognosis.
No full textAbstract
The cases of 5 patients with cerebral gliosarcomas examined by computed tomography are reported and the correlations among the computed tomographic (CT) findings, the surgical and histological aspects, and the prognosis are discussed. In some patients, these tumors appear on CT scan as intracerebral lesions, with large necrotic areas and peripheral contrast enhancement; this CT aspect, similar to that of glioblastomas, corresponds to a diffusely infiltrating growth of the tumor and the prevalence of a gliomatous component. In other patients, the tumor appears on the CT scan as a hyperdense mass with well-defined margins and homogenous contrast enhancement;; this CT finding, which may mimic that of a meningioma, corresponds to a rather well-demarcated surgical aspect and the prevalence of sarcomatous component. In our series, we have also noticed a more prolonged survival in a patient with a CT aspect that suggested a meningioma and prevalence of the sarcomatous component.</jats:p
