There are few case reports about application of F18-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in HPC [1]. A hemangiopericytoma-like growth pattern was frequently identified [2]. Histopathological diagnosis is mostly based on a "patternless pattern" on microscopic examination, which is a storiform arrangement of spindle cells combined with a "hemangiopericytoma-like appearance" and increased vascularity of the Lesion [3]. The aim of this study was to analyze the clinicopathological characteristics of SSTs and examine the immunohistochemical expression TFE3, which has not been studied in SSTs [4]. The observation of a sinunasal, infantile hemangiopericytoma affecting the anterior skull base and ethmoid Bone in a Female Infant is presented [5].

Here, we describe a case of a 10-year-old Child which initially presented with clinical features mimicking chronic suppurative otitis media and radiological presentation of a small intracranial abscess [6]. Besides a local lymph node metastasis, a Nodular Structure inside the left orbit caudal to the optic nerve showed increased uptake [7]. The use of now abolished labels, such as Malignant fibrous histiocytoma and hemangiopericytoma, has significantly hampered the chance of identifying specific entities [8]. An integrated diagnostic approach represents the only way to achieve a correct classification [9]. This study aims to investigate the clinicopathologic characteristics, diagnosis, differential diagnosis and prognosis of CNS SFT/HPC [10].

A T8/9 laminectomy and Excision of intradural extramedullary Lesion was performed, tumour section was sent for frozen section study, and more tissue was sent for paraffin studies and additional immunohistochemical staining [11]. On resection, the Mass was diagnosed as anaplastic hemangiopericytoma, WHO grade III [12]. This is the third case of anaplastic hemangiopericytoma in this region [13]. These included Lymphoma, Osteoma, and Rhabdomyosarcoma, Transitional cell Carcinoma arising from inverted papilloma, hemangiopericytoma, Spindle cell Sarcoma, Pituitary adenoma, Giant cell Sarcoma, Malignant undifferentiated tumour, plexiform neurofibroma and sinonasal tuberculosis [14].
