Female, 68 years old, with headache and tremors, known small cell lung cancer, evaluate for metastases. Motion artifact degrades image quality on several sequences. No evidence of mass effect or pathologic parenchymal or extra-axial enhancement is seen. No restricted diffusion is evident. Encephalomalacia of the right inferior frontal lobe is likely related to prior infarction. Scattered periventricular T2 hyperintensities are also noted, most likely representing chronic microvascular ischemic disease. On postcontrast images, the pituitary gland appears to be inhomogeneously enhancing with an area of relative hypoenhancement posteriorly.No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles are within normal limits for size and morphology.
1.No evidence of intracranial metastatic disease within the limitations of a motion degraded examination.2.No definite acute intracranial abnormalities. Sequelae of chronic right inferior frontal infarction are noted along with findings likely related to chronic microvascular ischemic disease.3.Incidental note is made of asymmetric hypoenhancement of the posterior aspect of the pituitary. This is probably an incidental finding and unrelated to the patient's presenting symptoms. If clinical concern warrants, dedicated pituitary imaging can be considered.
