FINDINGS: There is a well-defined (~4 x 5 cm) cystic mass in left temporal lobe extending into adjacent deep parietal lobe along the sylvian fissure and associated with surrounding vasogenic edema, mass effect over the adjacent brain parenchyma, ipsilateral lateral ventricle, uncal herniation and subfalcine herniation of 9 mm. Pressure over third ventricle with entrapment & dilatation of the contralateral lateral ventricle is also noted. No other discrete concomitant lesion is noted in other cerebral hemisphere or below the tentorium. CONCLUSION: Well-defined cystic lesion in left temporo-parietal lobes associated with mass effect over the adjacent brain, raising the suspicion of metastasis.
