[|Human|] MRI BRAINMRI of the brain was performed using T1 & T2 weighted sequences in multiple planes.There is no signal abnormality detected in the cerebral parenchyma.The brainstem and cerebellum are normal.The ventricles, cisterns and sulci are normal.Intracranial vessels display expected flow void.Both the 7th-8th nerve complexes appear normal. No abnormal thickening or mass lesion is seenalong their course on this unenhanced scan. The visualised vestibulo-cochlear apparatus appearnormal.Polyp / retention cyst is seen in the left maxillary antrum.
[|AI|]  Hi, Your MRI reveal retention cyst in left maxillary sinus. Retention cysts of the maxillary sinus are an incidental finding on radiographs. These cysts usually appear as rounded, dome-shaped, soft tissue masses, most often on the floor of the maxillary sinus. Most retention cysts of the maxillary sinus spontaneously regressed or showed no significant change in size over the long term. , in the absence of associated complications, "wait and see" may be the appropriate management strategy for these retention cysts.
