Clinical question: Evaluate sinuses. Signs and symptoms: New headaches with sinusitis. Pre- and post enhanced brain MRI:No diffusion-weighted abnormalities.There is normal anatomical morphology/development of brain and with normal signal intensity on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination.No detectable abnormal parenchymal or leptomeningeal enhancement.Unremarkable calvarium and orbits and without abnormal enhancement.All visualized mastoid air cells and middle ear cavities are unremarkable.There is minute mucosal thickening in the dependent right maxillary sinus. There is minute mucosal thickening in the left dependent maxillary sinus and a small retention cyst measuring approximately at 15 x 16 mm. All other paranasal sinuses demonstrate normal pneumatization signal pattern. There is moderate leftward deviation of nasal septum and suspected small bony septal spur which is in contact and deforms the mucosal lining of the left inferior turbinate.
1.Negative pre and post enhanced brain MRI.2.Minimal chronic maxillary sinusitis and unremarkable all paranasal sinuses otherwise.3.Moderate leftward nasal septum deviation and suspected a small bony septal spur as detailed.
