Abstract:
A 30-year-old patient presented with bilateral shoulder pain, hematoma of the upper arm and livid discoloration of the tongue. Blood analysis showed an increase in creatine kinase and inflammatory markers. Screening for immunological and infection markers were negative. Under the suspicion of systemic vasculitis, a positron emission tomography-computed tomography (PET-CT) scan was performed, which instead revealed fractures of the greater tuberosities of both humeri and a suspicious brain lesion. A secondary generalized epileptic seizure due to a World Health Organization (WHO) grade III astrocytoma with subsequent traumatic luxation and fracture of both shoulders, hemarthrosis and tongue bite was diagnosed.
