ABSTRACT
The infection with non-tuberculous mycobacterium correlates highly with immunodeficiency. Mycobacterium xenopi (M. xenopi) is most commonly isolated in the respiratory tract, as a cause of endogenous spondylodiscitis it occurs but rarely. Only seven such cases have been reported in literature. In this paper, we present the case of an about 28-year-old HIV-positive patient with a long history of back pain. MRI of the spinal column and Positron Emission Tomography with (18)F-fluorodeoxyglucose as a tracer (F18-FDG-PET) confirmed the suspected spondylodiscitis. After performing a CT-controlled abscess drainage the patient's condition improved. Because of the severe destruction of the spinal segment concerned and because of the epidural abscess formation a vertebrectomy of T10 and surgical debridement of the paravertebral soft tissue via thoracotomy became urgently necessary. The spine was stabilized by interposing a cage and an anterolateral monobar system. M. xenopi could be proven by PCR out of the intraoperative specimen. After operation and antituberculotic therapy there was a fast convalescence. Diagnostics, therapy, and clinical outcome are discussed.

Progressive multifocal leukoencephalopathy is caused by JC virus, an opportunistic infection of the central nervous system. Antiretroviral treatment for progressive multifocal leukoencephalopathy in human immunodeficiency virus-infected patients is beneficial, but few data exist for patients who are not infected with human immunodeficiency virus. Idiopathic CD4+ T lymphocytopenia excludes human immunodeficiency virus infection. We describe a patient with progressive multifocal leukoencephalopathy with underlying idiopathic CD4+ T lymphocytopenia in whom functional recovery occurred without antiviral therapy.
