Hemangiopericytoma is an aggressive, highly metastatic tumor of the soft tissues and meninges. Metastases have been reported in the liver, lungs, bones and rarely other organs. To the best of our knowledge, 18 cases of pancreatic metastases have been reported, but none have been described in the radiology literature. We report a case of hemangiopericytoma with metastasis to the pancreas and describe the CT imaging features of hemangiopericytoma with a review of the literature.

Background: While SBRT to NSBM has become common, particularly in the oligometastatic population, the approach to treating non-spine bone metastases (NSBM) with stereotactic body radiotherapy (SBRT) varies widely across institutions and clinical trial protocols. We present a comprehensive systematic review of the literatures to inform practice recommendations on behalf of the International Stereotactic Radiosurgery Society (ISRS).
Methods: A systematic literature review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Background: Adenoid cystic carcinoma (ACC) is a rare malignant tumor that accounts for <1 % of head and neck malignancies, with an estimated involvement of the tongue at approximately 3 %.
Case Presentation: This report presents a case of a 42-year-old male with no significant history of tobacco or alcohol use, who developed a painless, progressively enlarging mass on the ventral surface of his tongue over the course of eight months. Initial surgical resection confirmed the diagnosis of ACC, which necessitated a right hemiglossectomy followed by radiotherapy to address potential residual disease.

Purpose: To present the case of a young patient with BRAF V600E-mutant cutaneous melanoma who developed bilateral choroidal metastases complicated by neovascular glaucoma (NVG) in both eyes following the interruption of nivolumab therapy.
Methods: A 28-year-old female with primary cutaneous melanoma of the left hand underwent surgical resection and adjuvant nivolumab. Immunotherapy was discontinued due to immune-related acute interstitial nephritis.
