“…In fact, there are only a few case reports about angiomatous meningiomas and clinical studies regarding this issue are very rare. To the best of our knowledge, there are exist only two series about clinical features of angiomatous meningiomas [67]. …”

BackgroundAngiomatous meningioma is a rare histological subtype of meningioma. Therefore, this specific medical condition is rarely reviewed in the literature. In the present work, we report the clinical and radiological features with postoperative outcomes of angiomatous meningioma.MethodsThis retrospective study included the patients who were pathologically diagnosed with angiomatous meningioma after surgical resection between February 2010 and September 2015 in our institute. We analyzed the clinical data, radiological manifestation, treatment and prognosis of all patients.ResultsThe 15 patients (5 males and 10 females) were diagnosed with angiomatous meningioma during the study period. The median age of patients at the time of surgery was 63 years (range: 40 to 80 years). According to Simpson classification, 7, 5, and 3 patients achieved Simpson grade I, II, and IV resection, respectively. In the follow-up period, recurrence was noted in one patient. Ten out of the 15 patients showed homogeneous enhancement. Two patients demonstrated cystic changes. There was no occurrence of calcification or hemorrhage in our patients. Characteristically, 14 out of 15 patients showed signal voids of vessels. Significant peritumoral edema was observed in the majority of tumors (67%).ConclusionAngiomatous meningiomas are rare benign meningioma. Brain images of angiomatous meningioma usually demonstrate signal void signs and peritumoral edema. In the present study, angiomatous meningiomas showed good prognosis after surgical resection.

“…The most important diagnostic feature is short extension of contrast enhancing tissue along the dura which is also known as dura tail [1]. Angiomatous meningioma seems to have more obvious signal voids of vessels in the tumor on MRI [4].…”

“…For cases with residual tumor after surgery, radiation therapy can be used for treating these patients [4]. The molecular basis of the effectiveness of radiation therapy is that radiotherapy can inhibit the expression of vascular endothelial growth factor (VEGF) and somatostatin receptor, which causes blood vessel contraction to reduce blood supply and then shrink the tumor [7].…”

Papillary meningioma is an uncommon meningioma subtype of World Health Organization grade III. It could show some radiologic profiles pointing to malignant behavior, such as a cystic change, a heterogeneous enhancement, and an ill- defined border. However, to date, the radiologic profile described in this article has not been reported in previous literatures, and it is just the characteristic being considered as the major cause for patients’ death. A 16-year-old adolescent boy with a 6-month history of headache was admitted to our department on June 28, 2012. Magnetic resonance imaging showed a giant well-defined mass in the left temporal region, with a severe flow void on T2-weighted image and an abundant stripelike enhancement on T1-weighted contrast-enhanced scan. In view of its middle cranial fossa location (one predilection site for meningioma), meningioma was suspected preoperatively. A regular left frontotemporal craniotomy was performed. Unexpectedly, extreme hemorrhage happened intraoperatively, and it was difficult to stop the bleeding. After identification of no hemorrhage in the operative cavity through intraoperative magnetic resonance imaging, the operation was finished, with an overall blood loss of 15,000 mL. The patient died of brain stem dysfunction the second day after the operation.
