Presentation
Left bronchogenic carcinoma on follow up. History of left occipital craniotomy for solitary brain metastasis.
Patient Data
Left upper lobe mass averaging 5.6 x 3.3 x 5.8 cm. It extends medially to the mediastinal pleura and laterally to the lateral costal pleura. Its shows mild heterogeneous enhancement with areas of break down. Amputation of the left upper bronchus. Attenuation of the left upper pulmonary vessels.
Background of diffuse emphysematous changes.
Evidence of two intra-axial space-occupying lesions noted at the grey-white matter junction within the right frontal region and the left temporoparietal region, the largest in the former reaching 18 mm. Both lesions showed ring enhancement with central necrosis as well as extensive disproportionate vasogenic oedema and mass effect.
Subcentimetre non-enhancing lesion also noted at the right medial temporal region showing T2 hyperintensity with haemosiderin rim and marked blooming on SWI, likely incidental cavernoma.
Cortical and subcortical encephalomalacia noted at the left occipital region, sequel to previous surgical intervention.
Right frontal developmental venous anomaly (DVA) is incidentally noted.
Case Discussion
Known patient with metastatic lung carcinoma showing two parenchymal brain deposits.
