BACKGROUND: Surgical treatment of giant pituitary adenomas is sometimes challenging. We present our surgical series of giant nonfunctioning adenomas to shed light on the limitations of effective and safe tumor resection. METHODS: The preoperative tumor characteristics, surgical approaches, outcome, and histology of giant nonfunctioning adenoma (>40 mm) in 128 consecutive surgical patients are reviewed. The follow-up period ranged from 19 to 113 (mean 62.2) months...

Dural sinus malformation (DSM) is a rare paediatric vascular malformation characterised by abnormal dilation of the posterior dural sinus. Owing to its rarity, the pathophysiology of DSM has not been fully elucidated. We report a case of prenatally diagnosed DSM with an unusual clinical course. We detected DSM in a male foetus in the 26th week of gestation by using foetal ultrasonography. Although the DSM regressed during the foetal stage and the arteriovenous shunt was insignificant in the neonate, the shunt rapidly developed four months after birth...

The granulation pattern of somatotroph adenomas is well known to be associated with differing clinical and biochemical characteristics, and it has been shown that sparsely granulated tumours respond poorly to commonly used somatostatin receptor ligands (SRLs). We report a challenging case of acromegaly with a sparsely granulated tumour resistant to multiple modalities of treatment, ultimately achieving biochemical control with pasireotide. A 26-year-old lady presented with classical features of acromegaly, which was confirmed by an oral glucose tolerance test...

Cavernous sinus thrombosis (CST) is a rare condition that is usually associated with infections, pregnancy, vasculitis and some types of medication, such as the contraceptive pill and paraneoplastic. Primary Burkitt lymphoma (PBL) of the thyroid gland is very uncommon and the clinical description of such cases has been largely limited to case reports. In this paper, we present a case of CST as the first manifestation of PBL of the thyroid gland. To the best of our knowledge, our patient is the first case report of PBL of the thyroid gland that presents with bilateral CST...

Two main causes of arterial thrombosis are known: fi rst - atherosclerosis, extensively studied, and the second - atrial fi brillation. The lack of any risk factors and the occurrence at young age of a thrombotic event requires us to investigate possible other conditions, including inherited thrombophilia that is represented by a series of genetic disorders that increase the risk of thromboembolic disease. The role of thrombophilia in the occurrence of arterial thrombosis is inconsequential; this disorder is characterized by the tendency of developing venous thrombosis...

A 50-year-old woman presented with gradually increasing right-sided facial numbness. Neuroimaging revealed a lesion in the right cavernous sinus mimicking meningioma. The resection of the right cavernous sinus neoplasm was implemented via endoscopic endonasal approach under general anesthesia. Histological examination of the surgical specimen revealed adenoid cystic carcinoma. Adenoid cystic carcinoma in the cavernous sinus is extremely rare as a primary lesion and challenging to manage. Little data exist to guide treatment when this tumor extends to involve the structure of cavernous sinus...

REVIEW
Javier Ros de San Pedro
Posterior communicating aneurysms are commonly associated with oculomotor nerve palsy. However, trigeminal nerve involvement among these aneurysms is a rare event with no previous analysis. In order to describe the main features of posterior communicating aneurysms causing trigeminal neuralgia (TGN-PComAAs) eight cases (six from the literature plus two more illustrative cases) were included in the present series. All cases were thoroughly studied in order to collect their epidemiological, radiological, clinical, therapeutic, pathogenic, and outcome data...

BACKGROUND: Intracranial saccular aneurysms are acquired lesions that often present with neuro-ophthalmologic symptoms and signs. Recent advances in neurosurgical techniques, endovascular treatments, and neurocritical care have improved the optimal management of symptomatic unruptured aneurysms, but whether the chosen treatment has an impact on neuro-ophthalmologic outcomes remains debated. EVIDENCE ACQUISITION: A review of the literature focused on neuro-ophthalmic manifestations and treatment of intracranial aneurysms with specific relevance to neuro-ophthalmologic outcomes was conducted using Ovid MEDLINE and EMBASE databases...

Traumatic carotid cavernous fistula (CCF) presents most commonly as a direct connection between the cavernous segment of internal carotid artery (ICA) and cavernous sinus (CS), and often accompanies basal skull fracture (BSF). The most frequently reported signs and symptoms are proptosis, chemosis, and bruit. Epistaxis is uncommon symptom of CCF. A 63-year-old man with a history of BSF due to blunt head trauma eight months previously was referred to our emergency room for massive epistaxis. Cerebral angiography demonstrated a high-flow CCF with a connection between the supraclinoid portion of left ICA and CS via a pseudoaneurysm, suggesting the life-threatening epistaxis had been caused by high-flow shunting, through the gap created by the BSF...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. It is characterized by multiple xanthogranulomatous masses throughout the body, predominantly in the tibia. One of the characteristic radiological findings of the lesions associated with ECD is a "coated artery," which is often observed in the aorta. Although approximately one-fourth of ECD cases involve the central nervous system (CNS), an intracranial-coated artery has only been reported in four cases. We report a case of ECD that involves the CNS and has the unique appearance of a coated vertebral artery (VA)...

Pituitary Apoplexy (PA) is defined as a clinical syndrome comprising headache, visual deficits and altered sensorium, which can result from haemorrhage or infarction of the pituitary gland. Acute ischaemic stroke following PA is very rare. We are presenting a 35-year-old young otherwise healthy lady who presented with neuro ophthalmological and vascular symptoms on a background of PA. Imaging revealed a pituitary macro adenoma with parasellar extension with internal bleed. Cerebral angiography revealed that the mass compressed the bilateral cavernous sinuses (left more than right), resulting in obliteration of the cavernous portion of the left Internal Carotid Artery (ICA)...

BACKGROUND: Direct carotid-cavernous sinus fistulas (CCF) are high flow arteriovenous shunts that are typically the result of a severe head injury. The endovascular treatment of these lesions includes the use of detachable balloons, coils, liquid embolic agents, and covered stents. To minimize the chance of treatment failure and subsequent complications, endoluminal reconstruction using a flow-diverting stent may be added to the treatment construct . METHODS: We present 3 cases and review the existing literature...

We present a case of sub-total cavernous sinus thrombosis secondary to Panton-Valentine leucocidin-associated Staphylococcus aureus pyomyositis of the muscles of mastication in a previously healthy child, who was successfully managed with no residual disease. He was found to have a factor V Leiden heterozygous mutation. We highlight the propensity of PVL-SA to induce venous thrombosis at any site, but with potential for more severe consequences in the head. We highlight pyomyositis as a differential for peri-orbital cellulitis, and discuss the significance of the factor V Leiden mutation...

Bilateral traumatic carotid-cavernous fistula(CCF)is rare. It is most commonly caused by a direct head or face injury involving the cavernous sinus and develops immediately after trauma. We report a case of bilateral traumatic CCF that occurred as an intracerebral hematoma(ICH)mimicking apoplexy 5 months later. We treated the patient with point occlusion of venous reflux causing an ICH using coil embolization to remove the hematoma. Three days after we performed trans-venous occlusion of the intercavernous connection and right cavernous sinus using coil embolization through the right inferior petrosal vein, it was identified that the left CCF was occluded after first embolization into the left sylvian vein...

BACKGROUND: This case illustrates the importance of prompt assessment and treatment of orbital cellulitis. In fact the ocular signs and symptoms may be associated with systemic complications which should be investigated and identified as soon as possible to avoid a poor prognosis. CASE PRESENTATION: A 46-year-old white woman presented to our emergency room with proptosis, ophthalmoplegia, and conjunctival chemosis of her left eye. An ophthalmologist, having diagnosed orbital cellulitis in her left eye, suspected a cavernous sinus thrombosis...
