Male, 6 years old, with history of intracranial abscess, evaluate for change after one more month of antibiotics. Redemonstrated are findings related to prior right temporal craniotomy/craniectomy and mastoidectomy. The mastoidectomy bed continues to remain fluid opacified.The T2 hypointense, predominantly rim-enhancing nodule within the right inferior temporal lobe along the mastoid roof is unchanged in size measuring approximately 14 x 12 mm. The degree of T2 hyperintense signal surrounding this lesion, presumed to reflect edema, is also unchanged from the prior examination though it is improved when compared to older studies.No additional intracranial lesions are seen. Brain parenchymal morphology and signal characteristics are otherwise unremarkable. No evidence of significant generalized mass effect is seen. The ventricles are stable and normal in size.
1. No significant interval change in the size of the enhancing process along the inferior right temporal lobe.2. No significant interval change in the pattern or extent of mild edema surrounding this process.
