What tumor is most commonly reported to cause neoplastic intracranial aneurysms?

A CT report for facial trauma contains the following findings: "There is a mildly comminuted fracture involving the left frontal process of the maxilla and left nasal bone. Fracture lines in this region extend from the pyriform aperture across the medial maxillary buttress to the left inferior orbital rim, sparing the infraorbital canal. However, minimally displaced fractures involve the medial third of the orbital floor, internal orbital buttress, and the lamina papyracea. There is less than 0.5 mm outward herniation of extraconal fat into the ethmoid labyrinth. One of the fracture lines extends anteriorly to the frontomaxillary suture, liberating a minimally displaced fragment of bone containing the lacrimal fossa, which appears intact. The left lateral orbital wall is intact. There is a fracture of the medial wall of the maxillary sinus but not the lateral wall."

What classification best summarizes the most significant injuries?

A patient without prior medical history was involved in a motor vehicle collision and arrives obtunded. The patient undergoes noncontrast CT of the head and cervical spine. At the acquisition scanner, you identify scattered convexal subarachnoid hemorrhage and fractures of the right petrous temporal bone, characterized as otic-capsule sparing, coursing to the sigmoid plate, and not clearly involving the petrous carotid canal on that side. Based on this information, which of the following imaging tests is the most appropriate next step?

In a patient with infective endocarditis, which of the following locations is the most likely location of a mycotic (infectious) aneurysm?

A patient with untreated HIV (human immunodeficiency virus) infection in a developed country presents with altered mental status. Neuroimaging reveals multiple brain lesions associated with edema, contrast enhancement, and mass effect. What are the two most likely possibilities in the differential diagnosis?

A 20-year-old woman with severe vomiting and acute fatty liver of pregnancy, now post-delivery, developed seizures and coma and is assessed with the MRI shown. What is the most likely diagnosis?

A 20-year-old man with a history of alcohol use presents with confusion and headache and is assessed with the MRI shown. What is the most likely diagnosis?

A 25-year-old man with history of polysubstance use disorder presents with confusion and is assessed with the MRI shown. What is the most likely diagnosis?

A 70-year-old woman presents with 3 days of confusion and is assessed with the MRI shown. What is the most likely diagnosis?

A 50-year-old woman with history of suicide attempts, last seen well 2 days ago, is found down with a reduced level of consciousness. Rapid initial laboratory assessment was abnormal and she is assessed with the MRI shown. What is the most likely diagnosis?

Intrinsic T1 hyperintensity of the bilateral globi pallidi most likely reflects dysfunction of what organ?

A 45-year-old man is hospitalized for alcohol withdrawal. A few days into the hospitalization, he develops disordered movement and is assessed with MRI. What is the most likely diagnosis?

A 35-year-old has a seizure and is evaluated with MRI. What is the most likely diagnosis?

What is the most common location of cytotoxic lesions of the corpus callosum, such as those seen with seizure, antiseizure medication use/withdrawal, metabolic disturbances, and various other etiologies?

A 14-year-old with acute lymphoblastic leukemia presents with acute right hemiplegia and is evaluated with brain MRI. What is the most likely diagnosis?

A 70-year-old patient with no medical history presented with generalized tonic-clonic seizure. Head CT showed intracerebral hemorrhage. Based solely on these MR images, and presuming no hemorrhage was present in the deep grey nuclei or brainstem, what is the most likely diagnosis?

A 65-year-old patient presented with several months history of headaches and progressive cognitive decline. Based on only these MR images, what is the most likely diagnosis?

What is the best imaging descriptor for the marker of cerebral small vessel disease indicated by the arrow?

A 50-year-old woman, former smoker, undergoes chest CT for initial lung cancer screening. The report noted several pulmonary nodules that have a benign appearance. An incidental breast mass was present but not reported. Which of the following perceptual or cognitive biases most likely affected the radiologist's report?

A patient presents to urgent care clinic and thoracic spine radiographs were obtained. The provided indication was "trauma." The interpretation was "no acute fracture." The patient presented again several days later to the emergency department, at which time a nearly identical set of thoracic spine radiographs were obtained. The provided indication at this time was "pain, history of breast cancer, evaluate for metastasis." The interpretation was "absence of left T11 pedicle, most likely representing osteolytic metastasis", which was confirmed on subsequent CT.

What perceptual or cognitive bias most likely contributed to the diagnostic error at the first presentation?
