 There are unchanged postoperative findings related to right occipital craniotomy and occipital mass resection with residual susceptibility effect in the section cavity. There is a focus of enhancement along the superior margin of the postoperative bed measuring 7 x 2.5 mm on series 1201 image 50, decreased from 8 x 3 mm previously. There is unchanged moderate nonspecific confluent subcortical and periventricular white matter T2 signal abnormality. There is no acute infarct, mass effect or midline shift. There is unchanged right transfrontal ventricular catheter terminating in the third ventricle/level of the foramen of Monro. There is mild diffuse volume loss with stable ventricles. There is mild bilateral maxillary and scattered ethmoid sinus mucosal thickening.
1.Small focus of enhancement along the superior margin of the resection cavity in the right occipital lobe which is slightly smaller from most recent exam. This is favored to represent posttreatment findings although residual/recurrent tumor is not entirely excluded. Continued follow-up is suggested as clinically indicated.2.Essentially stable exam otherwise.
