Perilesional edema, associated or not with neurological manifestations, is a well-characterized finding in cases of calcified neurocysticercosis. There are no previous reports of HIV-related calcified toxoplasmosis that mimics this presentation of neurocysticercosis. We report on five patients, four of them with new-onset neurological manifestations, who showed brain calcifications associated with perilesional edema. All cases had a history of HIV-related toxoplasmosis and current virological and immunological control of HIV infection. Similar to neurocysticercosis, brain calcified toxoplasmosis may cause perilesional edema and symptoms in people living with HIV/AIDS.

Background And Purpose: Synthetic MRI utilizes the quantitative relaxometry parameters to generate multiple contrast images through a single acquisition. We tried to explore the utility of synthetic MRI derived relaxometry parameters in evaluation of ring enhancing lesions of brain.
Materials And Methods: This was a prospective study.

Perihematomal hypoperfusion may lead to ischemic damage during intraparenchymal cerebral hemorrhage (ICH), resulting in worse prognosis. We aimed to (1) investigate the relationship between serum biomarkers related to oxidative stress and vasoactive substances and the occurrence of hypoperfusion and ischemic perihematomal lesions in ICH and (2) evaluate their correlation with the volumetric evolution of the hematoma and perihematomal edema. We enrolled 28 patients affected by ICH.

There are few published descriptions of the MRI appearance of canine intracranial or spinal cord ependymoma. In this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ependymoma (three intracranial and three spinal cord cases). A consensus was reached when there was disagreement on specific features.

Background: Brain metastases (BMs) are the most common type of intracranial tumors, frequently arising from primary cancers such as lung, breast, melanoma, and renal cell carcinoma. Magnetic resonance imaging (MRI) plays a crucial role in assessing both the morphological and molecular characteristics of BMs, particularly in evaluating treatment response following radiosurgery. However, the interpretation of these imaging changes remains complex, often influencing clinical decision-making.

Multinodular and Vacuolating Neuronal Tumors of the cerebrum (MVNTs) are rare, seizure-related, low-grade tumors of the Central Nervous System (CNS) which usually affect young adults. First described by Huse et al. in 2013, these neoplasms are usually located within the deep cortical ribbon and the superficial white matter and have a characteristic cytoarchitecture of cells with neuronal and glial differentiation that form multiple nodules with conspicuous vacuolation.
