Question 1
A 68-year-old male presents 90 minutes after the sudden onset of right-sided hemiplegia and expressive aphasia. An emergent non-contrast head CT is performed. Which of the following early parenchymal ischemic signs is caused by cytotoxic edema causing loss of gray-white matter differentiation in the lateral basal ganglia?
Correct Answer:
Obscuration of the lentiform nucleus
Question 2
A 52-year-old female presents to the emergency department with a sudden-onset 'worst headache of life' and neck stiffness. Non-contrast head CT demonstrates extensive hyperattenuating subarachnoid hemorrhage centered in the basal cisterns and anterior interhemispheric fissure. What is the most common anatomical site of origin for a ruptured saccular intracranial aneurysm presenting with this pattern?
Correct Answer:
Anterior communicating artery
Question 3
A 58-year-old male presents with progressive headaches, personality changes, and new-onset seizures. Brain MRI demonstrates an intra-axial mass in the left frontotemporal white matter with a thick, irregular, nodular ring-enhancing wall, central non-enhancing necrosis, extensive surrounding T2/FLAIR vasogenic edema, and marked elevated cerebral blood volume (rCBV) on dynamic susceptibility contrast perfusion MRI. Which imaging feature most reliably differentiates glioblastoma multiforme (GBM) from a pyogenic brain abscess?
Correct Answer:
Elevated perfusion (high rCBV) and restricted diffusion in the enhancing rim rather than the necrotic center
Question 4
A 45-year-old female undergoes brain MRI for investigation of chronic headaches. Imaging reveals an extra-axial mass along the anterior convexity that is isointense to cortex on T1- and T2-weighted images, exhibits avid homogeneous contrast enhancement, and displays a tapering line of contrast-enhanced dura adjacent to the tumor margin. What is this tapering dural enhancement sign termed, and what is the most likely diagnosis?
Correct Answer:
Dural tail sign; Meningioma
Question 5
A 28-year-old female presents with subacute visual loss in the right eye followed by lower extremity paresthesias. Brain MRI reveals multiple ovoid T2/FLAIR hyperintense lesions oriented perpendicularly along the subependymal venules of the corpus callosum and callososeptal interface. What are these characteristic imaging findings called, and what do they represent?
Correct Answer:
Dawson fingers; Perivenular demyelinating plaques in multiple sclerosis
