New type of lacunar stroke presenting in brain perfusion images: A case report

Figure 1 Magnetic resonance images of the patient. A: Diffusion weighted imaging images, acute lacunar infarct in the left corona radiata; B: Apparent diffusion coefficient images; C: T2 images; D: T2 fluid attenuated inversion recovery images, hyperintense changes in the subcortical and periventricular white matter indicating small vessel ischemic changes; and old lacunar infarcts in bilateral centrum semiovale.

Figure 2 Single-photon emission computed tomography images of the patient: Decreased uptake in the right frontal lobe. A: Transverse section; B: Corona section.

Figure 3 Single-photon emission computed tomography-computerized tomography images of the patient. Decreased uptake in the left parietal lobe (grade 1); mild decrease in uptake in bilateral temporal lobes (grade 0-1); while the uptake values in the thalamus, and cerebellum, and bilateral basal ganglia are relatively normal.

Figure 4 Single-photon emission computed tomography images of the patient. A: Single-photon emission computed tomography (SPECT) images of the patient’s temporal lobe, showing reduced blood perfusion below the left parietal lobe in the SPECT image with “Q. brain” software; B: Shows decreased uptake in the left parietal lobe of the transverse image SPECT.
