Pretreatment Evaluation of Glioma
Glioma is considered the most common type of primary central nervous system (CNS) tumor. Imaging is crucial for diagnosis, characterization, grading, and therapeutic planning of CNS gliomas. Along with a…
Lymphomas–Part 2
There are 2 types of central nervous system lymphoma: primary and secondary. Both have variable imaging features making them diagnostic challenges. Furthermore, a patient’s immune status significantly alters the imaging…
Posterior Fossa Tumors in Adult Patients
In adults, the most common expansile “mass” lesion in the posterior fossa is a subacute stroke, whereas the most common neoplastic lesion in the posterior fossa is cerebellar metastasis (intra-axial)…
Adult Brain Tumors
Lara A. Brandão, MD, Editor This issue of Neuroimaging Clinics focuses on adult brain tumors. The most common posterior fossa tumors—metastasis and hemangioblastomas, among many differentials—are discussed in the first…
Lymphomas–Part 1
Primary central nervous system lymphomas are aggressive, high-cell-density tumors. There is recent increase in their incidence in immunocompetent patients. Knowledge of imaging findings on computed tomography and conventional MR imaging…
Adult Brain Tumors
Suresh K. Mukherji, MD, MBA, FACR, Consulting Editor Once again, it is my distinct pleasure to thank Lara Brandão for guest editing this issue of Neuroimaging Clinics . In this…
Advanced MR Imaging in Pediatric Brain Tumors, Clinical Applications
Advanced MR imaging techniques, such as spectroscopy, perfusion, diffusion, and functional imaging, have improved the diagnosis of brain tumors in children and also play an important role in defining surgical…
Extraparenchymal Lesions in Pediatric Patients
Extraparenchymal lesions of childhood include neoplastic and nonneoplastic entities. Lesions affecting children are different from the most common entities affecting adults. Although there are imaging features that are highly suggestive…
Pineal Region Masses in Pediatric Patients
A review of pediatric pineal region tumors is provided with emphasis on advanced imaging techniques. The 3 major categories of pineal region tumors include germ cell tumors, pineal parenchymal tumors,…
Neuroimaging of Peptide-based Vaccine Therapy in Pediatric Brain Tumors
The potential benefits of peptide-based immunotherapy for pediatric brain tumors are under investigation. Treatment-related heterogeneity has resulted in radiographic challenges, including pseudoprogression. Conventional MR imaging has limitations in assessment of…
