Diagnosis: Vertebral artery dissection Axial CTA with IV contrast (A, B) shows decreased caliber of the right vertebral artery (arrow) in comparison to the left, with soft tissue density encasing…
Diagnosis: Flexion distraction injury at L1 Sagittal CT of the thoracolumbar spine demonstrates a transversely oriented fracture through the spinous process of L1 (yellow arrow). No other fractures are evident….
Diagnosis: Aneurysmal subarachnoid hemorrhage Noncontrast head CT (left image) shows diffuse subarachnoid hemorrhage, more prominent on the left (yellow arrow). Coronal CTA MIP reconstruction (middle image) and lateral view of…
Diagnosis: Left parietal epidural hematoma with overlying fracture Noncontrast axial CT in brain window (left image) demonstrates a hyperdense extra-axial collection over the left parietal convexity (yellow arrow). A small…
Diagnosis: Flexion teardrop fracture at C7 Sagittal and axial CT images (left and middle images) demonstrate a small anterior teardrop fragment (yellow arrow) and retropulsion of the C7 vertebral body…
Diagnosis: Herpes simplex encephalitis Axial FLAIR (left image) and T2-weighted (middle image) MR images show edema and swelling of the right temporal lobe (arrows) with minimal mass effect upon the…
Diagnosis: Renal laceration extending into the collecting system (Grade IV traumatic renal injury) Contrast-enhanced axial CT (A,B) demonstrates a deep right renal laceration (yellow arrows) with hyperdense, hemorrhagic perinephric fluid….
Diagnosis: Atypical femoral insufficiency fracture in a patient on bisphosphonate therapy Frontal radiograph of the right femur demonstrates focal cortical thickening along the lateral aspect of the proximal femoral diaphysis…
Diagnosis: Lisfranc fracture–dislocation, homolateral type Frontal and oblique radiographs of the right foot demonstrate a comminuted fracture through the base of the second proximal metatarsal (yellow arrows). There is widening…
Diagnosis: Glioblastoma multiforme Contrast-enhanced CT (A) reveals an irregular, peripherally enhancing, centrally necrotic transcallosal mass (yellow arrows). Peritumoral low attenuation within the right frontal white matter (red arrow) represents a…
