Brain lymphoma development related to a long lasting epidermoid cyst.

Introduction: Epidermoid cysts (EC) are benign and slow growing lesions. A primary brain lymphoma development related to a EC is presented, second case described in literature.

Case Presentation: A woman 40 years old, harbouring a EC for more than 20 years, develops a fast growing brain lesion next to the EC.

¹⁸F-Fluorocholine PET/CT as a complementary tool in the follow-up of low-grade glioma: diagnostic accuracy and clinical utility.

Purpose: The follow-up of treated low-grade glioma (LGG) requires the evaluation of subtle clinical changes and MRI results. When the result is inconclusive, additional procedures are required to assist decision-making, such as the use of advanced MRI (aMRI) sequences and nuclear medicine scans (SPECT and PET). The aim of this study was to determine whether incorporating (18)F-fluorocholine PET/CT in the follow-up protocol for treated LGG improves diagnostic accuracy and clinical utility.

Early radiation-induced laryngeal malignant fibrous histiocytoma (MFH).

Postradiation sarcoma is a potential late sequela of ionising radiation and its frequency is rare. We present the case of a man with a radiation-induced malignant fibrous histiocytoma with a latent period of 20 months.
