Nailed Through Superior Sagittal Sinus: A Case Report and Surgical Considerations.

BACKGROUND AND IMPORTANCE: We report a case of nail gun-related penetrating brain injury, puncturing through the anterior third of superior sagittal sinus, which remained patent and was associated with an arteriovenous (AV) shunt revealed on catheter angiogram. CLINICAL PRESENTATION: A previously well 35-year-old male patient presented with a self-inflicted pneumatic nail gun injury. Neurological examination was unremarkable. Computed tomography (CT) of the brain demonstrated the nail had penetrated through the skull, traversed the anterior third of the superior sagittal sinus (SSS), right frontal lobe parenchyma, frontal horn of right lateral ventricle, caudate, and right cerebral peduncle. CT angiogram showed no associated vascular injury, with CT venogram showing a short segment of filling defect within SSS adjacent to nail penetration. However, digital subtraction angiography revealed an associated arteriovenous shunt 8 mm anterior to the dural penetration site, which filled the SSS in arterial phase. Removal of the nail was performed using a double concentric craniotomy around the nail entry site. Before removal of the nail, the SSS anterior to the nail penetration site was tied off and divided along with coagulation and division of the falx, while the SSS posterior to the nail penetration site was also tied off to isolate the penetrated SSS segment. The patient recovered well with repeat digital subtraction angiography demonstrating no residual AV shunting. CONCLUSION: This case report aims to highlight the importance of performing a catheter angiogram and describe our stepwise considerations and approach in treating a penetrating injury involving the superior sagittal sinus with concurrent AV fistula.

Aspergillus fumigatus cerebral abscess and sphenoid sinus osteomyelitis in an immunocompetent patient following previous nasopharyngeal carcinoma and radiotherapy.

Cerebral mycosis is extremely rare in immunocompetent patients. A 61-year-old male presented with a 3-month history of worsening left-sided headaches and 3-week history of left-sided upper lip paraesthesia. Magnetic resonance imaging revealed an enhancing lesion in the left temporal lobe. Histopathology of this lesion revealed what initially resembled a zygomycete but additional cultures obtained on further surgical debridement revealed the infection to be Aspergillus fumigatus with associated sphenoid sinus osteomyelitis. We postulate that the presentation was related to the patient's previous radiotherapy for nasopharyngeal carcinoma. To the best of our knowledge, this is the only report of such a case.

Giant extradural sacral meningioma.

We present the first case of primary benign fibrous meningioma restricted to the sacrum with no sign of recurrence after a long follow-up duration. This occurred in a 36-year-old man who initially presented with a 3-month history of right-sided sciatica. The tumour was successfully resected after three surgical procedures due to its high vascularity and technical difficulties. Sacroiliac joint stability was not disrupted, and he is still doing well clinically at 8 years follow-up.

The implications of ISAT and ISUIA for the management of cerebral aneurysms during pregnancy.

Both the International Subarachnoid Aneurysm Trial (ISAT) and the International Study on Unruptured Intracranial Aneurysms (ISUIA) have been widely extrapolated to influence the management of actual or anticipated aneurysmal subarachnoid hemorrhage (SAH). However, it remains possible that sub-groups exist for which such extrapolation might subsequently prove premature. In this review, we discuss the implications that such extrapolation may potentially have for one such SAH sub-group: the clinically rare scenario of SAH in pregnancy.

Benign fibrous histiocytoma of the thoracic spine: case report and review of the literature.

Benign fibrous histiocytoma (BFH) is a rare skeletal tumor, accounting for approximately 1% of all surgically managed benign bone tumors. Spinal location is very rare, and its management can be challenging, involving excision of tumor and spinal reconstruction and stabilization. The prognosis is good after treatment. The authors present the case of BFH involving the thoracic spine and a review of the literature concerning BFH of the spine.

Have ATLS and national transfer guidelines improved the quality of resuscitation and transfer of head-injured patients? A prospective survey from a Regional Neurosurgical Unit.

High-quality resuscitation and care during transfer of head-injured patients is essential to prevent secondary brain injury. We have prospectively assessed the standard of resuscitation in 50 consecutive head-injured patients transferred to our unit, and compared our findings with previous studies performed before the advanced trauma life support course (ATLS) had become widespread and national guidelines on the transfer of head injuries had been produced by the Association of Anaesthetists of Great Britain and Ireland (AAGBI). Delays in transfer, management of the airway, adequate cervical spine assessment, hypoxia (P(a)O(2) <13 kPa), hypotension (systolic BP <90 mmHg), missed injuries and the experience of the medical escort were compared against the standards laid out in ATLS and AAGBI Guidelines. The mean, unavoidable delay from arrival at the local accident and emergency unit to arrival was 7.4+/-1.9h (mean+/-95%CI) with most of the delay being prior to initial referral. Two patients arrived with an unsecured airway with a GCS=8/15; 26 had inadequate cervical spine imaging; 7 patients arrived hypoxic and 2 patients arrived hypotensive; most of these insults occurred during the transfer. Forty-six percent of medical escorts did not fulfil the minimum standard of experience. ATLS and AAGBI guidelines have provided only modest improvements in patient care at the expense of long delays in transfer. The incidence of hypoxia and hypotension remains unacceptably high.
