Tension pneumocephalus has been reported most frequently after posterior fossa surgery performed in the sitting position. We present a paediatric patient who developed tension pneumocephalus in the postoperative period after decompression of a craniopharyngioma performed with the patient in the supine position.

Pneumocephalus is a rare consequence of epidural anesthesia, which may occur following inadvertent or unidentified dural puncture when the loss of resistance to air technique is applied to identify the epidural space. Headache is the most common symptom presented in this condition, usually with sudden onset. This case report describes an unusual presentation of diffuse pneumocephalus after an u...

BACKGROUND Pneumocephalus is commonly associated with head and facial trauma, ear infection, or surgical interventions. Spontaneous pneumocephalus caused by a primary defect at the temporal bone level without association with pathological conditions is very rare. Few cases have been published with purely intraparenchymal involvement. We describe a rare case of spontaneous pneumocephalus arising...

A 43-year-old male trisomic patient was referred for acute left headache and progressive homolateral mydriasis and ptosis. Computed tomography and T2-magnetic resonance imaging demonstrated a 4 cm invasive pituitary adenoma (Panels A and C, respectively). Blood analyses revealed hyperprolactinemia (5460 ng/ml, normal values < 15 ng/ml) and severe gonadotrophic insuffi ciency. Treatment was clas...

Otogenic pneumocephalus is a rare condition. The case is described of pneumocephalus and meningitis secondary to acute otitis media. Although the rate of intracranial complications related to middle ear disease is only 0.5 to 4%, mortality still ranges between 5 and 15%.

conclusions pneumoventricle is rare but it can be established after spinal trauma. by awareness of such possibility, accurate diagnosis by clinical examination and imaging is essential for these types of injuries introduction the presence of air within the intracranial cavity, due to the entry of air secondary to an abnormal communication after a dural tear, is defined as pneumocephalus and int...

BACKGROUND Supratentorial pneumocephalus after posterior fossa surgery in the semisitting position may lead to decreased alertness and other symptoms. We here aimed to prove the efficacy of normobaric hyperoxia on the absorption of postoperative pneumocephalus according to a standardized treatment protocol. METHODS AND FINDINGS We enrolled 44 patients with postoperative supratentorial pneumoc...

Otogenic pneumocephalus is a condition of intracranial air originating from the middle ear or mastoid air cells. This communication between the intracranial cavity and the pneumatic cavities is usually associated with trauma after cranial fractures or iatrogenic trauma. We present a rare case of otogenic pneumocephalus arising in the left posterior fossa from wellpneumatized mastoid air cells. ...

A 73-year-old man presented with a loss of consciousness. He was comatose at the time of admission with a GCS of 5 and no localized neurological signs. Medical records indicated that the patient had undergone surgical treatment for esophageal carcinoma 2 years previously. Metastases developed in the reconstructed stomach tube and middle esophagus 6 months after surgery, and the patient had ther...

Pneumocephalus is defined as a collection of air within the cranial cavity. It is a common finding following head injury with skull base fracture and neurosurgical procedures. Tension pneumocephalus is a rare complication. The diagnosis is clinical and radiological with the characteristic Mount Fuji sign seen on computed tomography (CT). It is a neurosurgical emergency, and early recognition an...
