The landscape of brain tumor mimics in neuro-oncology practice

Acute cerebral hemorrhage mimicking glioblastoma on intraoperative magnetic resonance imaging: A case report

“…Although there are no reports concerning tumor mimics on intraoperative MRI, the prevalence on preoperative MRI is 3.4%-4.3% for CNS lesions and vascular etiology is common, ranging from 15.8% to 35.0% among them [2 , 3] . In the present case, an intraoperative acute cerebral hematoma mimicked a newly emerged GBM lesion on iMRI, which was eventually found to be a hematoma—a recent preoperative MRI was helpful in differentiating this lesion.…”

“…Magnetic resonance imaging (MRI) is now integral to neurosurgical practice as one of the most potent tools for lesion evaluation and differential diagnosis in brain tumor practice [1] . However, MRI sometimes shows lesions that can be mistaken for brain tumors, called “tumor mimics,” and this prevalence is 3.4%-4.3% among central nervous system (CNS) lesions [2 , 3] .…”

Patient survival based on temporal relationships between metastatic pancreatic cancer and brain metastases treated in a single institution: An opportunity for early detection

“…The incidence rate of brain metastases from all cancers ranges from 9 to 17% in population-based studies of can-cer patients [11]. This is likely an underestimate of the actual incidence rate, due to a myriad of factors including incomplete data sets and misdiagnosis resulting in patients with brain metastases infrequently undergoing autopsies [11]. Ductal adenocarcinomas tend to extend into adjacent structures such as the duodenum, the portal vein, or superior mesenteric vessels.…”
