Smarter MRI, from end to end

CLINICAL HISTORY: Chronic headaches, r/o intracranial pathology. Hx of mild TBI 2019. Pt reports intermittent visual disturbances x 3 months.

TECHNIQUE: Multiplanar multisequence MR imaging of the brain was performed without IV contrast on a 3T Siemens Magnetom Prisma scanner. Sequences include sagittal T1 MPRAGE, axial T2, axial FLAIR, axial DWI/ADC, axial SWI, coronal T2.

FINDINGS:

No evidence of acute infarction on diffusion-weighted imaging. No intra- or extra-axial hemorrhage identified on SWI sequences. Brain parenchyma demonstrates normal signal intensity on all sequences. Gray-white matter differentiation is preserved. No focal parenchymal signal abnormality. No mass effect or midline shift. Ventricular system is normal in size and morphology for patient age. No evidence of obstructive or communicating hydrocephalus.

Basal cisterns are patent. Cerebellar tonsils are in normal position relative to the foramen magnum. Corpus callosum is intact with normal morphology. Pituitary gland measures within normal limits, no focal lesion. Major intracranial flow voids are preserved bilaterally. Calvarium and skull base demonstrate no osseous abnormality.

Visualized paranasal sinuses demonstrate mild mucosal thickening in bilateral maxillary sinuses. Mastoid air cells are clear. Orbits are grossly unremarkable to the extent visualized.

IMPRESSION:

1. No acute intracranial abnormality. No evidence of hemorrhage, infarction, or mass lesion.
2. No significant signal abnormality identified within the brain parenchyma.
3. Incidental mild maxillary sinus mucosal thickening, likely inflammatory/allergic in etiology. Clinical correlation recommended.
