Aortic Valve Replacement and Penicillin Desensitization in a Patient with Abiotrophia defectiva Aortic Valve Endocarditis

Figure 2

Magnetic resonance imaging (MRI) and single-photon emission computed tomography-computed tomography (SPECT-CT) images of the spine suggestive of L3/L4 discitis. Sagittal-view MRI whole spine demonstrates hypointense T1-weighted signal (a) and hyperintense short tau inversion recovery- (STIR-) weighted signal (b) surrounding the L3/L4 vertebral disc consistent with edema, with no evidence of collection. SPECT-CT whole spine shows increased uptake surrounding the L3/L4 vertebral disc in both sagittal view and coronal view consistent with L3/L4 discitis.
