We report a 29-year-old woman who presented with severe headache, nausea and vomiting. A lesion was found in the left petrous ridge and near-total resection was performed. Pathologic examination showed anaplastic hemangiopericytoma (World Health Organization Grade III). Hemangiopericytoma is an
BACKGROUND
Hemangiopericytomas are potentially malignant vascular tumours. They are usually located in the thighs, the buttocks and the retroperitoneum. Recurrence is very common and they produce metastases that are not usually intracranial within a period of not less than 24 months. Treatment
BACKGROUND
Hemangiopericytomas are rare intracranial neoplasms that generally occur in the fifth decade of life and are commonly dural-based, supratentorial tumors. They are classified as World Health Organization grade II or III because of their aggressive nature with high rates of local recurrence
A 40-year-old male presented with hemangiopericytoma in the lateral ventricle manifesting as headaches persisting for 6 months associated with vomiting and visual obscurations for one month. Computed tomography and magnetic resonance imaging of the brain showed a large tumor in the trigone of the
The authors report on a patient with hemangiopericytoma(HPC). This 43-year-old female presented severe headache, vomiting and right homonymous hemianopsia. Magnetic resonance imaging and an angiogram showed a tumor above the left transverse sinus. The patient underwent a total resection of the tumor
BACKGROUND
Intracranial meningeal hemangiopericytoma (HPC) represents a rare and aggressive intracranial neoplasm located along the dural sinuses. It constitutes less than 1 % of all intracranial tumors and approximately 2-4 % of all meningeal tumors. The authors present our institute's experience
Objective: To investigate the clinical manifestations, imaging features, clinicopathologic features, and differential diagnosis of solitary fibrous tumors/anginoblastomas (SFT/HPCs) originating in the central nervous system. Methods: Sixty cases of SFT/HPCs originating in the central
This paper presents the case of an eight-year-old girl who presented with headache and vomiting and was found to harbor a right fronto-temporo-parietal, partially cystic and centrally solid tumor that measured 11 x 8 x 7 cm. This vascular tumor was gross totally removed. The initial histopathologic
BACKGROUND
Solitary fibrous tumors are rare benign mesenchymal neoplasms characterized by involvement of many sites all over the body with uncommon presentation within the cranium. Furthermore, malignant bilateral basifrontal solitary fibrous tumor is extremely rare. Although uncommon, this rare
BACKGROUND
Osteoblastoma is an uncommon primary bone tumor that involves any part of the skeleton. But its occurrence in the skull is extremely rare.
UNASSIGNED
A 30-year-old female was admitted to our hospital, because of the mass in the right frontal region with the history of headache for 3 years
The study was designed as retro-prospective and the study period was 3.5 years. A total of 66 (42 prospective and 24 retrospective) consecutive patients were included in the study. The commonest tumor in CPA is the Schwannoma (76%) followed by Meningioma (13.3%) and Epidermoid (4.44%). Unusual forms
A 61-year-old male presented with a recurrent solitary fibrous tumor (SFT) arising from the falx cerebri with intraventricular extension manifesting as nausea and vomiting. Magnetic resonance imaging showed the heterogeneously enhanced tumor in the falx, which extended to the bilateral lateral
This paper reports a case of glomus tumor of stomach from a male patient, 58 years old, with the chief complaint of nausea and vomiting after meal. This tumor was at the anterior wall of the antrum near the lesser curvature. By light microscopy, it was composed of glomus tumor cells and abundant
BACKGROUND
Phenylbutyrate (PBA), and its metabolite phenylacetate (PAA), induce growth inhibition and cellular differentiation in multiple tumor models. However, despite their potential anti-cancer properties, several pharmacodynamic aspects remain unknown.
METHODS
We conducted a dose escalating
