1/12. Multiple meningiomas, craniofacial hyperostosis and retinal abnormalities in proteus syndrome.Because clinical evidence suggests that proteus syndrome may be caused by a somatic mutation during early development, resulting in mosaicism, the possible types of abnormalities and their clinical distributions are highly variable. Here, we report on an unusual patient with proteus syndrome. Manifestations included multiple meningiomas, polymicrogyria, and periventricular heterotopias. Both eyes had epibulbar cystic lesions. The retina showed diffuse disorganization with nodular gliosis, retinal pigmentary abnormalities, chronic papilledema, and optic atrophy. Other abnormalities included progressive cranial, mandibular, maxillary, and auditory canal hyperostoses, epidermal nevi, and mental deficiency. The limbs were proportionate, and the hands and feet were normal.- - - - - - - - - - ranking = 1keywords = meningioma, meningiomas (Clic here for more details about this article) |
2/12. Intracranial low-grade chondrosarcoma with hyperostosis of the skull: a case report.We describe a case of intracranial chondrosarcoma in a 46-year-old woman. The preoperative diagnosis was meningioma as plain radiography and computed tomography of the head revealed a tumor with discrete calcifications predominantly in the right frontoparietal region and hyperostosis of the inner table of the skull overlying the tumor. However, the tumor was histologically composed of cartilaginous tissue without meningiomatous differentiation and the final diagnosis was a low-grade chondrosarcoma based on its histological appearance and size, together with the radiologic images. Intracranial chondrosarcoma occurring above the skull base is extremely rare and 19 cases were found in our literature review. Intracranial chondrosarcoma showing hyperostosis of the skull has not been reported in the cases. The discussion includes its differential diagnosis, origin, and clinical behavior.- - - - - - - - - - ranking = 0.36096572941012keywords = meningioma (Clic here for more details about this article) |
3/12. Primary ectopic meningioma.Primary ectopic meningiomas are rare. A case of a 16-year-old male who presented with a large mass in temporofrontal region is reported. X-ray skull showed soft tissue shadow with hyperostosis of frontal and temporal bone. CT scan of brain demonstrated a markedly enhancing lesion and bony hyperostosis with no intracranial component. Total excision of tumour with hyperostotic bone was done. Patient is well without any evidence of recurrence two years after surgery. Relevant literature is reviewed.- - - - - - - - - - ranking = 0.92193145882025keywords = meningioma, meningiomas (Clic here for more details about this article) |
4/12. A giant hyperostosing meningioma in a child.A case of 15-year-old boy with a giant hyperostotic meningioma is presented. The patient had a huge prominence at the posterior parietal region. The CT scan showed a giant intracranial tumor in the left parieto-occipital region under the hyperostotic bone. The tumor and hyperostotic bone were totally resected with the involved portion of the sagittal sinus. Histological study revealed a meningioma. The presence of such a huge hyperostosis and some peculiarities of childhood meningiomas are discussed.- - - - - - - - - - ranking = 1.2828971882304keywords = meningioma, meningiomas (Clic here for more details about this article) |
5/12. Harvey Cushing's Meningiomas text and the historical origin of resectability criteria for the anterior one third of the superior sagittal sinus.The search for the origin of the commonly held principle in current neurosurgery regarding the resectability of the anterior one third of the superior sagittal sinus unravels the many fascinating developments that occurred in neurosurgery during the early 20th century. All these occurrences can be traced back to, and are uniquely contextualized in, Harvey Cushing's seminal text, Meningiomas, Their classification, Regional Behaviour, life history, and Surgical End Results. Written with Louise Eisenhardt and published in 1938, Meningiomas is a monograph of incredible description and detail. The meticulous categorization of meningiomas, their presentation, clinical outcome, and surgical therapies are even further supplemented by Cushing's personal commentary, questions, and recollections. Cushing's genius was evident in his ability not only to make insightful clinical observations, but also to synthesize these ideas within the neurosurgical context of his era. As he says in Meningiomas, "Thus the pathological curiosity of one day becomes in its proper time a commonplace... most of which are one and the same disorder--had, for their interpretation, to await the advent of the Neurosurgeon."- - - - - - - - - - ranking = 0.2keywords = meningioma, meningiomas (Clic here for more details about this article) |
6/12. Hyperostotic meningioma with minimal tumor invasion into the skull.A 56-year-old man presented with a meningioma associated with hyperostotic bone containing little tumor cell infiltration. The patient presented with a growing mass on his right forehead and exophthalmos. Computed tomography (CT) taken 4 years previously revealed only hyperostosis without intracranial lesion. Repeat CT revealed an enhanced intracranial mass with overlying diffuse hyperostosis extending extracranially. The tumor and affected bone were widely removed. Histological examination confirmed rhabdoid meningioma in the intracranial and extracranial lesion. However, most of the hyperostotic bone showed no tumor cell infiltration. The cause of hyperostosis associated with meningioma is unclear, but tumor invasion is the generally accepted cause. In this case, hyperostosis occurred without tumor cell infiltration so another mechanism was probably involved. The extracranial extension occurred despite the disproportionately small tumor without global tumor cell infiltration of the bone or bony erosion.- - - - - - - - - - ranking = 1.2633800529354keywords = meningioma (Clic here for more details about this article) |
7/12. Giant calvarial hyperostosis with biparasagittal en plaque meningioma.We report a patient with an uncommon presentation in the form of massive bilateral calvarial hyperostosis with bi-parasagittal en plaque meningioma. The tumour was removed by bilateral fronto-parieto-occipital craniotomies. The patient was subjected to post operative radiotherapy to reduce the chances of recurrance. The management of such a case is a surgical challenge.- - - - - - - - - - ranking = 0.90241432352531keywords = meningioma (Clic here for more details about this article) |
8/12. Primary intraosseous meningioma. Case report.Primary intraosseous meningioma of the skull is an uncommon lesion often confused preoperatively with a primary bone tumor of the skull. The case of an intraosseous meningioma without dural connection or association with a cranial suture is reported that was radiographically diagnosed as Paget's disease and initially treated conservatively. Persistent headache prompted a biopsy, yielding a benign, heavily ossified, and psammomatous meningioma. The lesion was treated with wide surgical excision and acrylic cranioplasty. Subsequent review of the literature has revealed 35 additional cases of purely intraosseous meningioma. An analysis of these 36 cases demonstrates a mean patient age at diagnosis of 45 years and a 2:1 female preponderance, with the majority of lesions associated with cranial sutures. Sixty-four percent of the lesions were hyperostotic on plain skull x-ray films; the rest were osteolytic or a mixture of both. There was no relationship to prior trauma. The treatment of choice is wide surgical resection followed by cranial reconstruction.- - - - - - - - - - ranking = 1.4438629176405keywords = meningioma (Clic here for more details about this article) |

Meningiomas of the anterior skull base expanding into the orbit, paranasal sinuses, nasopharynx, and oropharynx.The natural progression of the infiltrative anterior skull base meningioma, expanding into orbit, paranasal sinuses, nasopharynx, and oropharynx during 12 years is presented. The development of the lesion is demonstrated on computed tomography. The patient was operated on six times from the age of 14.
