OBJECTIVE An association between breast cancer and intracranial meningioma has been described in women. We sought to determine whether this connection exists in men as well, hypothesizing that causes unrelated to sex may be responsible. METHODS We queried state cancer registries that recorded data on breast cancer and meningioma. International Classification of Diseases for Oncology codes for...

Background: Solitary fibrous tumor / hemangiopericytoma (SFT HPC) and fibroblastic types of meningioma have similarities that is difficult to distinguish based on histology. Immunohistochemistry STAT6 SSTR2A are definitive biomarkers in both tumors. Inversion-mediated fusions between two genes, NAB2 STAT6, were detected SFT HPC inducES proliferation cells. The somatostatin receptor (SSTR) 2 loc...

In order to provide an effective way to prevent or substantially delay the recurrence of invasive meningioma, and improve the curative effect of surgical treatment, we collected and analyzed the clinical manifestations, pathological features, preoperative imaging characteristics as well the data obtained during the surgical treatment of invasive meningioma. From February 2014 to February 2016, ...

Chordoid meningioma is an uncommon histopathological variant of meningioma with a peculiar chordoma-like appearance. Its association with systemic inflammatory disorder linked to Castleman's syndrome was confirmed in the majority of young patients, however such a relationship in adults remains enigmatic. We report two cases of chordoid meningiomas in adult patients without manifestation of Cast...

Meningiomas are the second most common intradural spinal tumors accounting for 25% of all spinal tumors. Being a slow growing and invariably benign tumor, it responds favorably to surgical excision. In addition, spinal meningioma has low recurrence rates. However, we experienced a case of intradural extramedullary spinal meningioma which recurred 16 years after the initial surgery on a 64-year-...

BACKGROUND Regression of meningioma has been reported after hemorrhage or hormonal withdrawal. However, meningioma regression is rarely observed spontaneously. CASE DESCRIPTION A right falx meningioma was incidentally diagnosed and was followed at every one-year by magnetic resonance imaging (MRI) for over 7 years. The tumor, with a maximum diameter of 4 cm, showed a slightly high density and...

Dural metastasis is a rare entity in clinical practice. We report a case of dural metastasis secondary to thyroid carcinoma, which on both preoperative CT and MRI and at surgery had the typical appearance of a meningioma. Histopathological findings confirmed metastatic follicular thyroid carcinoma as a primary site. Although rare, dural metastases can mimic a meningioma. Our experience in this ...

Meningioma is the most common nonglial intracranial primary tumor. It is a slowly growing tumor and presents clinically by causing seizures along with neurological or neuropsychological deficit. However, acute presentation of meningioma is possible. We are reporting a case of cerebral infarction due to a sphenoid wing meningothelial meningioma (with progesterone receptor positivity) leading to ...

1) Out of 160 primary meningeal tumors surgically treated, 10 cases had histologically malignant tumors. Of them two cases of sarcoma and one case of meningioma with marked invasiveness were filed in malignant (sarcoma) group, and six cases of angioblastic meningioma of hemangiopericytoma type and one case of meningioma with partial invasiveness in semi malignant group. 2) Average duration of s...

Osteoblastic meningioma is a subtypes of meningioma. Intracranial isolated osteoblastic meningioma is extremely unusual. We reported a case of osteoblastic meningioma in the right frontal region in a 15-year-old girl who presented with repeated unconsciousness for 20 days. Computed tomography (CT) revealed a well-defined calcified mass with CT value of 802.5 HU in the right frontal region next ...
