Abstract


Introduction. Although traumatic pneumocephalus is not uncommon, it rarely evolves into tension pneumocephalus (TP). Characterized by the presence of increasing amounts of intracranial air and concurrent appearance or worsening neurological symptoms, TP can be devastating if not recognized and treated promptly. We present two cases of traumatic TP and a concise review of literature on this topic. Methods. Two cases of traumatic TP are presented. In addition, a literature search revealed 20 additional cases, of which 18 had sufficient information for inclusion. Literature cases were combined with the 2 reported cases and analyzed for demographics, mechanism of injury, symptoms, time to presentation (acute 72 hours), diagnostic/treatment modalities, and outcomes. Case reports and literature review. Twenty cases were analyzed (17 males, 3 females, median age 26, range 8-92 years). Presentation was acute in 13/20 and delayed in 7/20 patients. Injury mechanisms included motor vehicle collisions (6/20), assault/blunt trauma to the cranio-facial area (5), falls (4), and motorcycle/bicycle crashes (3). Common presentations included depressed mental status (10/20), CSF rhinorrhea (9), headache (8), and loss of consciousness (6). Computed tomography (CT) was utilized in 19/20 patients. Common underlying injuries were frontal bone/sinus fracture (9/20) and ethmoid fracture (5). Intracranial hemorrhage was seen in 5/20 patients and brain contusions in 4/20 patients. Nonoperative management was utilized in 6/20 patients. Procedural approaches included craniotomy (11/20), emergency burr hole (4), endoscopy (2), and ventriculostomy (2). Most patients responded to initial treatment (19/20). One early and one delayed death were reported. Conclusions. Traumatic TP is rare, tends to be associated with severe cranio-facial injuries, and can occur following both blunt and penetrating injury. Early recognition and high index of clinical suspicion are important. Appropriate treatment results in improvement in vast majority of cases. CT scan is the diagnostic modality of choice for TP.
