Parasagittal Meningioma

Most clinicians consider a peripheral nerve lesion in patients with drop foot. However, causes stemming from the central nervous system represent rare, important, and underappreciated differential etiologies. Central causative lesions usually occur at locations where pyramidal tract connections are condensed and specific and the function is somatotopically organized. Here we report case presenting as central foot drop or spastic foot-drop and other myriad clinical features which after investigations was found due to bilateral parasagittal meningiomas.

Angiographic Diagnosis

Clinical observation of the patient with parasagittal meningioma at the level of the middle third of the superior sagittal sinus and falx is presented. When such tumors are removed, the main task is to prevent damage to the parasagittal veins, the injury of which can cause a persistent neurological defi cit in the postoperative period. A feature of this case is the complex use of advanced minimally invasive methods of angiographic diagnosis when planning surgical treatment, which signifi cantly increases the chances of a successful outcome of the operation.

Parasagittal Meningioma

Pulmonary metastases of benign meningiomas are extremely rare. The case of a 34-year-old man with bilateral parasagittal meningioma who developed pulmonary metastases is described. The meningioma was an enormous hypervascular tumor with invasion of the superior sagittal sinus. The tumor was resected completely and histologically diagnosed as transitional meningioma. The Ki-67 labeling index was 5%. Four months after operation, the patient subsequently developed bilateral multiple lung lesions later identified as metastases. The lung lesions were partially removed surgically and histologically diagnosed as meningothelial meningioma WHO grade I. The Ki-67 labeling index was 2%. The histological findings demonstrated that the tumor occupied the arterial lumen and the perivascular space, suggesting that pulmonary tumors might metastasize via the vascular route. The histopathological features and mechanisms of metastasizing meningiomas are reviewed and discussed.

✓ Mutism is defined as a state in which a patient is conscious but unwilling or unable to speak. It has been reported to occur in association with a multitude of conditions, including trauma, epilepsy, tumors, stroke, psychoses, and brain surgery. The cases of two patients who became mute in the immediate postoperative period are presented. The first patient developed mutism following removal of a parasagittal meningioma, and the second following removal of a posterior fossa medulloblastoma. It is believed that transient injury may have occurred to the supplementary motor cortex in the first case and to the dentate nuclei in the second case. It is interesting that these two areas are connected via pathways involving the ventrolateral nucleus of the thalamus, and that lesions of this thalamic nucleus can also lead to mutism. It therefore appears plausible that interruption of these pathways may be involved in the pathogenesis of mutism. Although mutism is an infrequent complication of brain surgery, neurosurgeons should be aware that it may occur following removal of lesions in these areas and that it is generally a transient condition.

Parasagittal Meningioma

While the majority of intracranial meningiomas have an indolent clinical course, sudden and unexpected death may rarely occur. Two cases are reported to demonstrate rapid clinical deterioration resulting in death in individuals with large, grade I, parasagittal meningiomas. Case 1 was a 46-year-old man with a history of headaches and epilepsy who suddenly collapsed and died. A large right frontal parasagittal meningioma with haemorrhage had compressed the brain and lateral ventricle, causing tonsillar herniation. In case 2, a previously well 83-year-old woman presented with a one-week history of progressive dysphagia and dysphasia. She suffered rapid deterioration and was prescribed comfort care. A right-sided parasagittal meningioma had compressed the right superior and middle frontal gyri with posterior displacement and compression of the right precentral gyrus. If a meningioma is found at autopsy, the possibility of a lethal effect should be considered, and evidence of neurofibromatosis type 2 or other associated heritable conditions checked for.
