Primary mucosa-associated lymphoid tissue lymphoma in the midbrain: A case report

Figure 1 Imaging before treatment. A: Axial T2-weighted image shows heterogeneous intensity in the midbrain, and the midbrain aqueduct was compressed; B: Contrast-enhanced magnetic resonance imaging showing a significantly enhanced 1.9 cm × 1.8 cm-sized mass in the left midbrain; C: The lesion had high density on computed tomography; D: Fluorodeoxyglucose positron emission tomography showing that the lesion had increased glucose uptake (arrow). The maximum standardized uptake volume was 7.48.
