BACKGROUND
Atrio-oesophageal fistulas (AEFs) are an uncommon complication of pulmonary vein ablation, and its diagnosis is challenging. Multidisciplinary interventions and diagnostic imaging are usually required and may play a role in the initial assessment.
CASE SUMMARY
A 69-year-old female with atrial fibrillation who had undergone recent pulmonary vein ablation consulted with unspecific symptoms and sudden hemiparesis. Brain imaging showed pneumocephalus and acute infarcts. Chest computed tomography (CT) was highly suspicious for AEF. Surgical exploration revealed a swollen mediastinum attached to the right inferior pulmonary vein.
DISCUSSION
Non-specific symptoms after pulmonary vein ablation should prompt the suspicion of complications. In the presence of fever or neurological deficit, AEF must be suspected and assessed with a contrast-enhanced chest CT, which has become the gold standard. In brain imaging, pneumocephalus and multiple punctate acute infarcts might also indicate the presence of this complication.

We report here a very rare case of spontaneous intraventricular tension pneumocephalus. This case concerns a 40-year-old patient with a medical history of a tumor of the pineal region and secondary hydrocephalus treated by multiple ventriculoperitoneal shunts. He presented in the emergency room because of unusual headaches, nausea, and visual loss. In addition, he reported slight rhinorrhea for a few weeks. The initial brain CT scan revealed a spontaneous intraventricular tension pneumocephalus. There was no history of recent head trauma and no sign of disconnection of the shunt system. A complementary radiological assessment included a thin-slice bone CT scan and a radioisotope cisternography that revealed an osseous defect and an isotope leakage at the junction between the tegmen tympani and the squamous part of the left temporal bone. A middle cranial fossa surgery was performed to repair the osteo-meningeal breach.

Sellar reconstruction is important for preventing cerebrospinal fluid (CSF) leakage after transsphenoidal pituitary surgery. This report describes how, despite standard sellar reconstruction, CSF exudation resulted from dural thinning at the anterior skull base, outside the intrasellar area manipulated during pituitary tumor resection. A 76-year-old man underwent endoscopic transsphenoidal surgery for a pituitary tumor extending toward the anterior skull base. After opening the sellar floor, intractable bleeding from the anterior intercavernous sinus occurred during bone removal at the anterior skull base. Pseudocapsule-based extracapsular resection was completed after stopping the bleeding. On the 10th postoperative day, the patient developed CSF rhinorrhea complicated by marked pneumocephalus, and emergency endoscopic repair of the CSF leak was performed. CSF leakage originated from the thinned dura at the anterior skull base located outside the intrasellar area manipulated during tumor resection. The thinned dural area at the anterior skull base coincided with the site of intractable bleeding of the anterior intercavernous sinus during bone removal in tumor resection. The thinned anterior skull base dura was covered with fascia, overlaid with fat, and closed with the nasoseptal flap. Endoscopic CSF leak repair was successful. Severe damage to the anterior intercavernous sinus can cause extensive exposure of the single-layered inner meningeal dura, where thinning might result in CSF exudation. Therefore, use of autologous tissues to cover and reinforce the severely damaged area of the anterior intercavernous sinus might help prevent postoperative CSF exudation.

This case report presents a unique presentation of an intradiploic epidermoid cyst (IDEC) in a 55-year-old female. She presented with acute cerebellar symptoms triggered by a Valsalva maneuver. IDECs are a rare type of intracranial epidermoid cysts. They are benign and have a slow growth pattern that translates into progressively developing symptoms instead of acute symptoms. Symptoms include local deformities, focal neurologic deficits, and pain. This patient developed acute cerebellar symptoms due to erosion of the mastoid bone that created a pathway between the eustachian tube and the intracranial space via the mastoid air cells. Consequently, tension pneumocephalus emerged via a ball-valve effect that caused a significant mass effect in the posterior fossa. Surgical resection of the IDEC and closing of the mastoid air cells resulted in symptom relief by restoring the integrity of the intracranial-extracranial barrier. This case highlights that a higher level of vigilance is warranted for an IDEC in the proximity of aerated bone structures, such as the mastoid air cells and the paranasal sinuses, and that a more proactive approach is advocated.

Chronic subdural hematomas (CSDH) with isolated psychiatric presentation are rare. In this paper, we report a case of 77-year-old-female patient who had psychotic depression after repetitive head trauma without any neurological symptoms. The brain magnetic resonance imaging revealed an 20 mm subdural hematoma in the right frontoparietal region and a 7 mm subdural hematoma in the left frontal region. The psychiatric symptoms improved within the first week after evacuation but relapsed with the occurrence of right sided pneumocephalus. In the follow up, with the disappearance of the pneumocephalus, the psychiatric symptoms improved. It should be kept in mind that isolated psychiatric symptoms can be seen due to subdural hematoma and evacuation of the hematoma has an important role in improving the psychiatric symptoms.

This case study describes a fatal head injury in a 1-year-old child involved in a motor vehicle accident in Japan. The child, secured in a rear-facing child seat, was a passenger in a car driven by their mother when the offset car-to-car collision occurred. The car rotated counterclockwise before coming to a stop. Despite remaining secured in the child seat, the child suffered severe head trauma, leading to cardiac arrest. Autopsy computed tomography revealed a right open depressed fracture, left head contusion, traumatic subarachnoid hemorrhage, intraventricular hemorrhage, and pneumocephalus. The injury mechanism involved the child's head striking the right headrest, followed by a swing to the left, induced by the initial impact and subsequent rotational movement. This case highlights the importance of age-specific data in understanding pediatric injuries in motor vehicle accidents and improving child seat safety measures.

Review
RATIONALE
Gamma knife stereotactic radiosurgery (GKRS) is a recognized safe and effective treatment for brain metastasis; however, some complications can present significant clinical challenges. This case report highlights a rare occurrence of cerebrospinal fluid (CSF) leakage and pneumocranium following GKRS, emphasizing the need for awareness and prompt management of these complications.
PATIENT CONCERNS
A 35-year-old male with a history of malignant neoplasm of the lip in 2015 and perineural spread of malignancy into the left cavernous sinus was treated with GKRS in 2017. The patient was admitted emergently 39 days after discharge due to persistent headache and dizziness.
DIAGNOSES
Brain computed tomography (CT) revealed diffuse bilateral pneumocranium alongside an observation of CSF leakage.
INTERVENTIONS
A surgical procedure involving a left frontal-temporal craniotomy was performed to excise a residual skull base tumor and repair the dura, guided by a navigator system. The conclusive pathological assessment revealed the presence of squamous cell carcinoma markers.
OUTCOMES
The patient exhibited excellent tolerance to the entire procedure and experienced a prompt and uneventful recovery process. After surgery, the symptoms alleviated and CSF leak stopped. The follow-up image showed the pneumocranium resolved.
LESSONS
Pneumocranium due to early-stage post-GKRS is uncommon. The rapid tumor shrinkage and timing of brain metastasis spreading through the dura can lead to CSF leak and pneumocranium. We reviewed current treatment options and presented a successful craniotomy-based dura repair case.

Tension Pneumocephalus Secondary to Positive Pressure Ventilation Following Endoscopic Endonasal Skull Base Surgery: Three-Year Follow-Up After Implementation of an Institutional Protocol.
BACKGROUND
Tension pneumocephalus (PMC) is a rare and feared complication following the endonasal endoscopic approach (EEA) to skull base procedures. This is a neurosurgical emergency that requires urgent decompression to avoid catastrophic neurologic damage or death. An avoidable cause is the application of positive pressure ventilation (PPV) in EEA patients for postoperative hypoxia. Our institution implemented a hospital-wide protocol in response to this to identify and manage at-risk patients; this paper aims to identify if this protocol was effective in lowering the rates of tension PMC secondary to PPV.
RESULTS
In the 3 years following the implementation of the protocol, 110 patients underwent EEAs, from which 1 case of tension PMC (found to be not secondary to PPV) was identified. This is compared with 2 cases of tension PMC secondary to PPV over the preceding 5 years, out of 406 EEA patients. This constitutes a quantifiable reduction in PPV-related tension PMC in both standard and extended approach EEAs, signifying the effective uptake of the protocol.
CONCLUSIONS
We found no cases of tension PMC after PPV following EEA skull base surgery in our institution since the implementation of an institution-wide guideline. This underscores the utility of our simple and cost-effective preventative protocol in reducing the overall rates of tension PMC following the inadvertent postoperative application of PPV. Further research is needed to study the comparative risks and benefits of PPV in the post-EEA patient and thus inform future iterations of the protocol.

is a bacterium commonly found in the oral cavities of cats and dogs. Infections are particularly common in immunocompromised patients who have been exposed to bites or come in contact with saliva from these animals. The manifestations of infection include bacteremia, fever, and, rarely, meningitis. Diagnosis is challenging given the bacteria has slow growth on culture media. The organism is susceptible to beta-lactam antibiotics, with higher-generation cephalosporins recommended for treating meningitis. We present a case of a 74-year-old woman with altered mental status and no signs of immunosuppression. She was diagnosed with meningitis caused by , with an intriguing finding of pneumocephalus, which is a rare occurrence as per literature review.

A 4-year-old boy was referred to our tertiary hospital after a penetrating adnexal injury by a large-breed dog to the left orbital area. There was an increase in lacrimation, which was thought to be due to an inflammatory reaction. However, it was discovered that the lacrimation increased in the reverse-Trendelenburg position and with the Valsalva maneuver. Halo sign and beta transferrin test were positive, which led to the diagnosis of cerebrospinal fluid (CSF) fistula, and the patient was operated using a supraorbital craniotomy. A dural tear was visualized and sutured appropriately, then fibrin glue and an autologous galeal graft were applied to the tear. The CSF oculorrhea stopped postoperatively, and the patient was discharged after 10 days of follow-up. The patient had no recurrent CSF leakage at 4-year follow-up. Although CSF oculorrhea is rare and may be difficult to discern from lacrimation, the presence of pneumocephalus and halo sign should suggest fistula repair.
