Other symptoms and signs involving cognitive functions and awareness [R41.89], Reason for Study: ^Reason: mild cognitive impairment - assess for volume loss or CVD History: mild memory problems There is about 10.3mm sized well circumscribed high T1, low T1 lesion on the right parapharyngeal space adjacent to the deep lobe of the right parotid gland. There is no other space occupying lesion seen on this scan. No evidence of lymph node enlargement. Diagnostic possibility of this lesion include minor salivary gland mass or could be an extension of the deep lobe of the right parotid gland benign looking mass lesion such as pleomorphic adenoma. There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no intracranial mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Extracranial well circumscribed lesion on the right parapharyngeal space. Benign salivary gland mass such as pleomorphic adenoma can be a possibility from either minor salivary gland or extension of the deep lobe of the right parotid gland origin. Either Neck CT scan or Neck MRI with and without contrast enhancement can be considered for further imaging evaluation if clinically indicated.2. No evidence of acute ischemic or hemorrhagic lesion on this scan.
