Three cases of cystic meningioma encountered in one year are presented. It appears from a review of the literature, and an analysis of these three cases, that large xanthochromic cerebral cysts may be associated with meningiomas in any of three configurations: (1) centrally within the tumour; (2) peripherally within the tumour; (3) in the adjacent brain. Regardless of which configuration applie...

BACKGROUND Papillary meningiomas are rare meningeal tumors and are associated with aggressive clinical behavior as compared with other meningiomas. Because of their rare occurrence, they may pose a diagnostic dilemma to the unwary pathologist. We report a case of papillary meningioma in a 16-year-old boy. CASE PRESENTATION A 16-year-old boy presented with complaints of headache, progressively...

Meningiomas are common and mostly benign intracranial tumors, but may show a histological progression to malignancy. The mechanisms of malignant transformation remain unclear. Malignant meningiomas usually bear a high recurrence rate and unfavorable prognosis, and multiple surgical resections are required for the treatment. We report on a case of 51-year-old woman with a histologically benign i...

There are numerous studies on the immune response against malignant human tumors. This study was aimed to address the complexity and specificity of humoral immune response against a benign human tumor. We assembled a panel of 62 meningioma-expressed antigens that show reactivity with serum antibodies of meningioma patients, including 41 previously uncharacterized antigens by screening of a feta...

OBJECTIVE The purposes of this article are to present 5 cases of intracranial meningioma with leptomeningeal dissemination (LD) and investigate the characteristics of this disease. METHODS We present a retrospective case series of 5 females at our institutions (age ranged 21-72 years, mean 54.6 years) diagnosed with LD of an intracranial meningioma after surgery between 1998 and 2013. A datab...

BACKGROUND Intracranial meningioma and glioma collision tumors are relatively uncommon and are even more rarely located within the ventricles. CASE PRESENTATION Here, we report a case of a patient with an intraventricular meningioma and astrocytoma collision tumor. A 39-year-old man previously underwent excision of an astrocytoma in the triangle area of the lateral ventricle and exhibited goo...

Fifteen percent of intracranial tumors are represented by meningiomas. Meningioma is usually a benign neoplasm; malignant histology is rare and represents about 2-10% with a 43% incidence of metastasis. The most frequent site of metastasis is the lung and rare are other sites. There are no definitive criteria to predict the recurrence or metastases of meningioma and histological grading, accord...

normal 0 false false false en-us x-none ar-sa radiation therapies are commonly used for malignant or metastatic brain tumors for curative and palliative use. the radiation-induced neurotoxicity includes both parenchymal and vascular damage. here we report the case of a 43-year-old woman who developed multiple sclerosis (ms) 9 months after she underwent the last session of radiotherapy for the d...

We report a case of malignant intraventricular meningioma with CSF drop metastases and an implantation metastatic subgaleal nodule in a 53-year-old woman. Malignant intraventricular meningiomas are rare with only seven cases being reported in the literature. These tumours can be very aggressive and one should consider immediate postoperative radiotherapy.
