Vertebral mucormycosis. A 22-year-old female after allogeneic HCT for relapsed AML and a history of pulmonary and CNS mucormycosis presented with new-onset back pain. MRI scan of the spine showed a pathological fracture of the L3 body, paravertebral enhancement, a complex nondisplaced fracture of S1, and a right-psoas abscess (FRFSE, fast recovery fast spin echo). The psoas abscess was drained, and hyphae were seen by microscopy. L1-L3 laminectomy and L3-L4 corpectomy were performed, and pathology showed osteomyelitis and hyphae.
