Secondary malignant neoplasm of brain [C79.31] / Acute lymphoblastic leukemia not having achieved remission [C91.00], Reason for Study: ^Reason: 61yo F w/ Ph+ ALL with weakness, gait instability, right arm weakness, please eval for brain lesion. Previously noted right side corona radiata T2/FLAIR high signal intensity lesion appears to be slightly increased or equivocal in size since prior scan [11.7mm(RL) x 19.3mm (AP) x 16.5mm (CC); was 9.2mm (RL)x 17.4mm(AP) x 16.6mm (CC) previously]. Again the lesion is not associated with restricted diffusion or local mass effect, and thus non specific.Other scattered high signal intensity lesions at the right frontal lobe, bilateral periventricular white matter do not show any significant interval change since prior scan.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no 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. Slightly increased in size or equivocal right coronal radiata T2/FLAIR high signal intensity lesions as described above. Follow up scan with contrast enhancement can be considered for further imaging evaluation.2. Otherwise no remarkable finding.
