Synthetic MRI derived relaxometry parameters: a new insight into characterization of ring enhancing lesions of brain.
Neuroradiology
December 2024
Division of Neuroimaging and Interventional Neuroradiology, Department of Radiodiagnosis and Imaging, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.
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.
Giant cerebellar neurocysticercosis masquerading a primary central nervous system neoplasm - A case report with review of literature.
Surg Neurol Int

Department of Pathology and Laboratory Medicine, All India Institute of Medical Sciences, Rishikesh, Uttarakhand, India.
Background: Neurocysticercosis (NCC) is one of the leading parasitic infections of the brain. Giant NCC is rare, with only two cases of cerebellar involvement reported till now. In the presence of a host immune response, these giant NCCs can mimic primary central nervous system neoplasms.

Article Synopsis
- Ring-enhancing lesions are commonly found in patients with weakened immune systems, often due to conditions like HIV/AIDS or cancer, and can result from infections, tumors, or vascular issues.
- A South American male in his 30s, with no previous medical history, arrived at the emergency department after a seizure, leading to brain imaging that revealed a solitary ring-enhancing lesion.
- Despite thorough testing and consultations, including negative results for major infections, it was determined that the lesion stemmed from a prior infection, making this case significant given his lack of known risk factors.
Infectious brain abscesses and granulomas: analysis of 110 episodes in adults.
BMC Neurol
November 2024
Clinical Research Development Unit, Faculty of Medicine, Imam Reza Hospital, Mashhad University of Medical Sciences, Mashhad, Iran.
Background: Infectious brain abscesses and granulomas, characterized by localized collections of pus or inflammatory tissue within the brain parenchyma, pose significant clinical challenges due to their potentially life-threatening nature and complex management requirements.
Methods: This cross-sectional study investigated patients diagnosed with infectious brain abscesses and granulomas from March 1, 2012, to October 22, 2021, in Mashhad, Iran. Data were collected from adult patients admitted to the two primary referral centers for community-acquired neuroinfections and neuroinflammations.
Cranial nerves bridging the middle ear and cerebellum causing cerebellar peduncle abscess: A case report.
Acta Radiol Open
October 2024
Department of Neurosurgery, University of Iowa Hospitals and Clinics, Iowa City, IA, USA.
Cerebellar abscess is a reported complication of chronic suppurative otitis media (CSOM) and is life threatening at times. It usually develops by direct spread of CSOM through the bony erosion in the petrous bone or by thrombophlebitis of the sigmoid sinus. However, an alternative pathway of infection transmission from the petrous bone to the cerebellum through the anatomical bridge of the cranial nerves has possibly not been described before.
