[Intracerebral lesions after TNF-alpha inhibitor therapy with pre-existing sarcoidosis and sacroiliitis].

This article reports the case of a 55-year-old man who presented with aphasia caused by intracerebral lesions and had a history of pulmonary sarcoidosis. Due to nonsteroidal anti-inflammatory drug-resistant spondyloarthritis TNF-alpha inhibitor treatment was started after a negative tuberculosis screening. Subsequently the patient developed pulmonary tuberculosis and cerebral tuberculoma reactivated by the TNF-alpha inhibitor therapy accompanied by pulmonary sarcoidosis with sacroiliitis and oligoarthritis. This case report emphasises the risk of atypical tuberculosis infections under TNF-alpha inhibitors despite negative results of tuberculosis screening.
