Aspergillosis is a rare cause of spondylitis. Moreover, early diagnosis by MR imaging and adequate treatment can prevent the serious complications of fungal infection. To our knowledge, the MR findings of multilevel aspergillus spondylitis in the cervico-thoraco-lumbar spine have not been previously described. Here, we report the MR findings of aspergillus spondylitis involving the cervical, thoracic, and lumbar spine in a liver transplant recipient. spergillosis is a rare cause of spondylitis, and early diagnosis by MR imaging and adequate treatment are essential for a good outcome (1 3). Although the MR findings of bacterial spondylitis have been fully described (4, 5), the findings of aspergillus spondylitis have been rarely described, and to the best of our knowledge multilevel involvement of cervico-thoraco-lumbar spine has not been previously reported. Here, we report the MR imaging findings of aspergillus spondylitis involving the cervico-thoraco-lumbar spine in a liver transplant recipient.
CASE REPORTA 46-year-old man underwent liver transplantation due to hepatitis B virus cirrhosis in March 2005, and subsequently was treated using routine immunosuppression therapy. However, his early postoperative course was complicated by pulmonary aspergillosis. About 10 weeks after liver transplantation a left lower lobe wedge resection and pathology showed aspergilloma, and about three weeks after this thoracic surgery the patient complained of back pain. Plain radiography of the lumbar spine demonstrated no abnormality, and although his back pain was treated conservatively, the patient complained of progressive back pain.MR imaging of the lumbar spine revealed band-like or diffuse hypointense signals in vertebral bodies L2 to L5 on T1-weighted images (Fig. 1A), which were isointense to slightly hyperintense on T2-weighted images (Fig. 1B). In detail, T1-weighted images showed some hypointense signals with preservation of intranuclear clefts in the L2 3 and L4 5 discs, but disc hyperintensity was absent and intranuclear cleft loss was visualized in the L3 4 disc. In addition, endplate irregularities were apparent in the involved spine. Disc space narrowing was observed at L3 4 and L4 5, and band-like or diffuse enhancement was observed in involved vertebral bodies with an epidural abscess (Fig. 1C). A paraspinal abnormal signal was relatively well-defined (Fig. 1D). The MR based diagnosis was of tuberculous spondylitis rather than pyogenic spondylitis. At surgery, infected granulation tissue and disc material with pus were found at the
