Clinical question: Evaluate underlying structural lesions. Signs and symptoms: Headaches. Pre and post enhanced brain MRI:No diffusion-weighted abnormalities.Examination demonstrates normal anatomical development, morphology and signal intensity of brain parenchyma on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.There is normal anatomical variation of partially empty sella.No detectable abnormal enhancement of brain parenchyma or the leptomeninges.The signal void of major intracranial arterial branches are identified.The signal intensity of the intracranial venous sinuses are within normal and with normal pattern of enhancement.Unremarkable calvarium and orbits and without detectable abnormal enhancement.Paranasal sinuses demonstrate a moderate size retention cyst in the right maxillary sinus and unremarkable paranasal sinuses otherwise.Pre- and post enhanced cervical MRI:Examination demonstrates normal signal intensity and anatomical alignment of the vertebral column.There is normal signal intensity and caliber of cervical and upper most visualized thoracic cord.There is no detectable abnormal enhancement of the vertebral column, cord or the leptomeninges.There is mild degenerative disc disease at C6-C7 and with subtle bulging disc as well as a tiny annular fissure with expected enhancement. No spinal stenosis or neural foraminal compromise at any level.
1.Pre and post enhanced MRI of brain is unremarkable. Moderate size right maxillary sinus dictation cyst and unremarkable paranasal sinuses.2.Pre- and post enhanced MRI of cervical spine demonstrate normal signal intensity and caliber of the cord without abnormal enhancement. Mild degenerative disease and a central annular fissure at C6/C7 with expected enhancement. No spinal stenosis or neural foraminal compromise at any level.
