Context: Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare.
Case Report: We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.

Introduction: Solitary fibrous tumor (SFT) represents an uncommon mesenchymal neoplasm affecting primarily the extremities and deep soft tissues with, overall, benign but locally aggressive biologic behavior and an underlying pathognomonic NAB2::STAT6 fusion. Intraosseous SFTs are infrequent, and involvement of the jawbones is exceedingly rare.
Case Presentation: A 54-year-old woman presented with an asymptomatic, well-demarcated, multilocular radiolucency of the left posterior mandible featuring focally irregular borders, root resorption and lingual cortex perforation.

Evaluating masses of mesenchymal and epithelial origin accurately using computed tomography (CT) has several limitations in dogs. This study aimed to present dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters to aid in improving the diagnostic accuracy for masses of mesenchymal and epithelial origin in veterinary medicine. Four dogs diagnosed with benign and malignant soft tissue sarcoma (STS), cholesteatoma, or squamous cell carcinoma underwent CT, conventional MRI, and DCE-MRI.
