A 61-year-old man was wheeled in to our emergency triage bleeding profusely from his mouth and nose in an unconscious state. His Glasgow Coma Scale was 7 and was intubated for airway safety. A failed anterior nasal packing was followed by insertion of a Foley urinary catheter through the right nostril to secure posterior nasal packing and haemostasis. CT of the brain following nasal packing showed diffuse traumatic subarachnoid haemorrhage and basifrontal contusions with multiple fractures of the anterior cranial fossa, cribriform plate including the frontal sinus. Multiple specs of air in the frontal lobe was initially mistaken as pneumocephalus (Hounsfield unit −971) (figure 1). The Foley catheter had inadvertently found its way to the brain through the cribriform plate, and the bulb was inflated just above the defect (figure 2). The catheter was deflated and removed soon after imaging. The patient underwent a right frontotemporoparietal craniectomy with basal repair for his severe head injury. The patient had a prolonged hospital stay and finally succumbed to severe head injury.
Facial trauma is commonly associated with fractures of the anterior skull base, frontal sinus, cribriform plate, ethmoid air cells and the sphenoid sinus, with profuse bleeding from the oro-nasal orifices. Although posterior nasal packing is contraindicated in such patients, it is often the first line of management in an emergency setting prior to arterial ligation/embolisation.1 Urinary catheters are the most common balloon catheters used for this purpose. While cranial migration of nasogastric tube is not an uncommon occurrence, only five cases of accidental urinary catheter passage into the intracranial cavity have been reported.2 It is usually associated with a high mortality of >50% and complications such as intraparenchymal haemorrhage, hemiparesis, meningitis and cerebrospinal fistula.3 In the event of an absolute necessity to introduce these endonasal apparatus, it should be under direct or endoscopic visualisation confirmed with fluoroscopy. Thus, fractures of the anterior cranial fossa are a contraindication for endonasal procedures and should be dealt with extreme caution.
Anterior cranial fossa and cribriform plate fractures are a contraindication for posterior nasal packing
Passage of endonasal tubings into the brain parenchyma is associated with high mortality and complications such as haemorrhage, meningitis and Cerebrospinal Fluid (CSF) fistulas.
