We describe a patient with traumatic carotid-cavernous fistula (CCF), subsequently developing contralateral extensive hemorrhagic venous infarction from retrograde venous reflux into the opposite basal vein of Rosenthal. A 54-year-old woman was involved in a motor vehicle accident and sustained severe traumatic brain injury. Two months later, she developed bilateral proptosis and audible bruit. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain demonstrated the right direct CCF...

Purpose: Carotid cavernous sinus ectasia is a rare cause of abducens nerve palsy. Observation: We present a case of severe unilateral progressive esotropia resulting from cavernous sinus carotid vascular ectasia in a 67 y/o female. She had progressive esotropia over the years with no neuroimaging despite having regular ophthalmic care. Magnetic resonance imaging determined the etiology of her chronic severe esotropia. Conclusion and importance: Carotid cavernous sinus ectasia should be considered in the differential of severe progressive unilateral abducens nerve palsy...

OBJECTIVE: The anterior transpetrosal (ATP) approach is the most appropriate approach for petroclival meningiomas, which are typically located from the dorsum sellae to the upper border of the internal acoustic meatus (IAM). Although neurosurgeons can resect over this area if the tumor is detached from the dura, tumors within the indication area for petroclival meningiomas is insufficient for the selection of the ATP approach because it can be difficult to evaluate whether the tumor is attached or only touching the dura...

OBJECTIVE The endoscopic endonasal approach (EEA) and the transcranial approach (TCA) are good options for the treatment of tuberculum sellae (TS) meningiomas. The objective of this study was to identify the key anatomical features in TS meningiomas and compare the two surgical approaches. METHODS The authors retrospectively reviewed clinical data in 178 patients with TS meningiomas treated at 3 institutions between January 2010 and July 2016. Patients with tumors encasing the internal carotid artery or anterior cerebral artery or involving the anterior clinoid process or cavernous sinus were excluded...

Blastomyces species are thermally dimorphic fungi existing as yeast in tissue. We report an initially immunocompetent patient with orbital apex syndrome (OAS) whose presentation suggested giant cell arteritis. Subsequently, metastatic carcinoma was entertained as a cause of OAS until bronchoscopy yielded Blastomyces species. The patient rapidly succumbed with multiorgan failure despite Amphotericin B administration. At post-mortem, Blastomyces co-infection with fungal hyphae in keeping with Aspergillus species was found in cavernous sinus and in infarcted optic nerve...

A healthy 51-year-old female presented with a spontaneous direct carotid-cavernous sinus fistula associated with a persistent primitive trigeminal artery. She had no history of connective tissue or cerebrovascular disorders or significant head trauma. This is a rare lesion with only 18 previously reported cases. It had similar clinical presentation and imaging appearance to a high-flow direct carotid-cavernous fistula and was uncovered after successful trans-venous coil embolisation of the fistula. It therefore needs to be considered in cases of direct carotid-cavernous fistula without history of trauma...

A 33-year-old female patient presented with diplopia and left eye ptosis 26 weeks into her first pregnancy. No investigation was conducted at the time and her symptoms subsided 4 weeks post partum. This same phenomenon occurred during second pregnancy at 20 weeks of gestation, with patient becoming symptom-free again 6 weeks after giving birth. MRI revealed a lesion in the left cavernous sinus in keeping with a meningioma. Due to the surgically challenging location, the lesion was treated with gamma knife radiosurgery...

BACKGROUND: Most target areas for facial volumization procedures relate to the anatomical location of the facial or ophthalmic artery. Occasionally, inadvertent injection of hyaluronic acid (HA) filler into the arterial circulation occurs, and unrecognised, is irreparably associated with disastrous vascular complications.Of note, the site of complications, irrespective of the injection site, is similar, and falls into only 5 areas of the face, all within the functional angiosome of the facial or ophthalmic artery...

Brain abscess (BA) is an encapsulated infection and can be the consequence of head and cranio-maxillo-facial surgery or trauma, or may be secondary to cavernous thrombophlebitis, but is most frequently due to hematogenous septic dissemination from an adjacent site of infection, such as the paranasal sinuses, middle ear or oral cavity. We report a rare and unfortunate case of multiple BA caused by dental procedures in a young man with undiagnosed patent foramen ovale (PFO). Simple routine dental procedures, such as tooth brushing and professional oral hygiene, can predispose to life-threatening conditions...

BACKGROUND: HPV-associated OSCC (HPV-OSCC) has been determined to be a distinct disease entity from non-HPV associated OSCC. Patients affected by HPV-OSCC generally have a more favourable prognosis, with improved rates of locoregional control and survival compared with their non-HPV counterparts. Despite this, HPV-OSCC has a similar rate of distant metastases. Interestingly, recent evidence has emerged that demonstrates more frequent atypical metastasis patterns when compared to non-HPV associated disease...

We report a case of a cavernous haemangioma arising from the left trigeminal nerve causing mass effect, midline shift and hydrocephalus. Surgical resection was attempted after immediate insertion of bilateral extra-ventricular drains, but complete resection was not achieved, with residual disease at the superior orbital fissure and cavernous sinus. Stereotactic radiosurgery was deemed unsuitable in view of proximity to the left optic nerve and optic chiasm, and the patient was hence treated with fractionated external-beam radiation therapy (RT) to a total dose of 40 Gy in 20 daily fractions over four weeks...

Mouret abscess is a rare extracranial complication of suppurative otitis media. It is generally believed to be a deep neck abscess caused by inflammation leading to the rupture of the bony tip of the mastoid tip. The location of Mouret abscess is deep. The symptoms are insidious at the onset, but may eventually spread to the surrounding tissue, and even lead to mediastinal abscess, cavernous sinus thrombosis, meningitis, dyspnea and other serious complications. At present, with the popularization of antibiotics, the occurrence rate of Mouret abscess is very low, and only sporadic cases have been reported...

To evaluate the clinical value of three-dimensional (3D) CT reconstruction of the sphenoidal sinus separation in localizing sellar floor during endonasal transsphenoidal surgery, and determine the size and location of sellar floor fenestration. After exclusion,51 patients were eligible for study inclusion. A pre-operative CT scan of the paranasal sinus and CT scan and MRI of the pituitary gland were obtained. Sphenoidal sinus separation was reconstructed using Mimics 15.0 software and the quantity, shape, and orientation were observed and compared with intra-operative data, the purpose of which was to guide the localization of sellar floor...

INTRODUCTION: Sixth nerve palsy is a common complication of endovascular treatment for carotid-cavernous fistulas (CCF). Two hypotheses are evoked: the spontaneous venous congestion into the cavernous sinus (CS), and the direct compression of the nerve by the embolic agent into the CS. Nevertheless, the evidence is still uncertain. Knowing the vicinity of the sixth nerve with the inferior petrosal sinus (IPS) in the Dorello's canal, we hypothesized that the recanalization of the IPS increased the risk of nerve damage...

OBJECTIVE: Hyperprolactinemia is common in acromegaly and in these patients, insulin-like growth factor (IGF)-1 level may decrease with dopamine agonist. We report a series of patients with prolactinoma and a paradoxical increase of IGF-1 levels during cabergoline treatment. METHODS: Clinical characteristics and response to treatment of patients with prolactinomas, in whom normal or slightly elevated baseline IGF-1 levels increased with cabergoline. RESULTS: The cohort consisted of ten prolactinoma patients (nine males, mean age 48 ± 14 years)...

OBJECTIVE Skull base meningiomas are surgically challenging tumors due to the intricate skull base anatomy and the proximity of cranial nerves and critical cerebral vasculature. Many studies have reported outcomes after primary resection of skull base meningiomas; however, little is known about outcomes after reoperation for recurrent skull base meningiomas. Since reoperation is one treatment option for patients with recurrent meningioma, the authors sought to define the risk profile for reoperation of skull base meningiomas...

We present a 43-old-male who suffered from a slowly progressive loss of vision in the left eye. Magnetic resonance (MR) imaging revealed a well-circumscribed contrast-enhancing lesion in the region of the anterior cavernous sinus and superior orbital fissure that extended into the optic canal. A schwannoma or meningioma was suspected. A transcranial surgery performed at another institution was not successful in removing the tumor and further deterioration of vision occurred. After resection of the left middle turbinate, the sphenoid and maxillary sinus were opened...

BACKGROUND: Granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis) is a multisystem vasculitis of small- to medium-sized blood vessels. Cranial involvement can result in cranial nerve palsies and, rarely, pituitary infiltration. CASE PRESENTATION: We describe the case of a 32 year-old woman with limited but severe GPA manifesting as progressive cranial nerve palsies and pituitary dysfunction. Our patient initially presented with localised ENT involvement, but despite treatment with methotrexate, she deteriorated...
