Longitudinal study of eight patients with meningeal abnormalities
| Patient No. | Meningeal Pathology | Initial Meningeal Findings and Changes on Follow-Up Studies | ||
|---|---|---|---|---|
| MR 1 | MR 2 (time interval) | MR 3 (time interval) | ||
| 1 | Tuberculosis | Meningeal enhancement along right sylvian fissure and adjacent sulci of temporal, high frontal lobes | Slightly more meningeal enhancement and thickening (20 days) | Unchanged (9 days) |
| 2 | Tuberculosis | Meningeal enhancement along left sylvian fissure and adjacent sulci of temporoparietal region | Markedly increased meningeal enhancement with adjacent brain parenchymal abnormality (21 days) | ——— |
| 3 | Bacterial Abscess | Diffuse pachymeningeal enhancement | Unchanged (7 days) | Decreased meningeal enhancement in both frontal regions (7 days) |

| 5 | Bacterial Abscess | Pachymeningeal enhancement in parasagittal, left frontal region and left occipital region | Decreased meningeal thickening and enhancement (1 month) | ——— |
| 6 | Lymphoma | Pachymeningeal enhancement in right frontotemporal region with adjacent subdural fluid collection | Unchanged (5 months) | Slightly increased meningeal enhancement and decreased size of fluid collection (2 months) |
| 7 | Breast Carcinoma | Marked focal nodular meningeal thickening at right temporal region | Increased thickening and enhancement of lesion (1 month) | ——— |
