Bilateral Posterior Fracture-Dislocation Of The Shoulder As A Presentation Of An Intracranial Tumor

Bilateral posterior-fracture dislocations of the shoulder are pathognomonic for seizure induced injuries. Patients that have not been diagnosed with a seizure disorder will often present with nocturnal injuries and no history of trauma. The allusive nature of this injury is compounded by mild presenting signs and symptoms and possible autoreduction with subsequent seizures. Therefore, a high degree of suspicion must be maintained for a seizure disorder as the cause for nocturnal injuries or posterior dislocations at the glenohumeral joint. Among the various causes of seizure disorders, we present a case in which a bilateral posterior-fracture dislocation served as a presenting sign of an intracranial tumor.
