“…Intracranial hemangiopericytoma is a rare mesenchymal tumor with strong aggressiveness and high degree of vascularization ( 1 ). Many features of intracranial hemangiopericytoma are similar to meningioma; intracranial hemangiopericytoma and meningioma both originate from the meninges and have similar imaging features.…”

“…Compared with angiomatous meningiomas, intracranial hemangiopericytoma is classified as a malignant tumor (WHO grades II–III) with the tendency of recurrence and metastasis ( 3 ). Intracranial hemangiopericytoma is more aggressive, highly vascularized and prone to intraoperative hemorrhage, has a higher postoperative recurrence rate and a worse prognosis ( 1 ).…”

BackgroundAccurate preoperative differentiation of intracranial hemangiopericytoma and angiomatous meningioma can greatly assist operation plan making and prognosis prediction. In this study, a clini-radiomic model combining radiomic and clinical features was used to distinguish intracranial hemangiopericytoma and hemangioma meningioma preoperatively.MethodsA total of 147 patients with intracranial hemangiopericytoma and 73 patients with angiomatous meningioma from the Tiantan Hospital were retrospectively reviewed and randomly assigned to training and validation sets. Radiomic features were extracted from MR images, the elastic net and recursive feature elimination algorithms were applied to select radiomic features for constructing a fusion radiomic model. Subsequently, multivariable logistic regression analysis was used to construct a clinical model, then a clini-radiomic model incorporating the fusion radiomic model and clinical features was constructed for individual predictions. The calibration, discriminating capacity, and clinical usefulness were also evaluated.ResultsSix significant radiomic features were selected to construct a fusion radiomic model that achieved an area under the curve (AUC) value of 0.900 and 0.900 in the training and validation sets, respectively. A clini-radiomic model that incorporated the radiomic model and clinical features was constructed and showed good discrimination and calibration, with an AUC of 0.920 in the training set and 0.910 in the validation set. The analysis of the decision curve showed that the fusion radiomic model and clini-radiomic model were clinically useful.ConclusionsOur clini-radiomic model showed great performance and high sensitivity in the differential diagnosis of intracranial hemangiopericytoma and angiomatous meningioma, and could contribute to non-invasive development of individualized diagnosis and treatment for these patients.

“…Its presentation in the central nervous system (CNS) is very rare, accounting for less than 1% of all intracranial tumours and 2–4% of meningeal tumours [ 2 ]. HPC has a slight male predominance and presents within the age range of 38–42 years [ 3 ]. Primary tumours are rarely diagnosed during pregnancy and central nervous system (CNS) tumours have no obvious clinical characteristics.…”

“… Highlights Haemangiopericytoma is a rare and aggressive type of soft tissue sarcoma that arises from pericytes of the capillaries and involves mostly the musculoskeletal system. Its presentation [ [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] ] in the central nervous system is very rare. Diagnosis was made at 34 weeks of pregnancy after several hospital admissions for nausea and vomiting starting at 20 weeks gestation.…”
