BACKGROUND: Paranasal sinus osteoma is a common, asymptomatic, histologically benign, and slow-growing tumor. However, it can give rise to secondary pathologies such as a mucocele in about 50% of the cases. Rarely, intracranial and orbital extension is present leading to rhinoliquorrhea, pneumocephalus, or neurological and visual impairment, which might be potentially life-threatening. CASE DESCRIPTION: A 49-year old man presented with an acute frontal lobe syndrome and rhinoliquorrhea...

OBJECTIVE: Non-gestational choriocarcinoma (NGC) is a rare germ cell tumor, reported less than 0.6% of all gestational tumors, and has a poor prognosis when metastasized. NGC is even less reported with metastasis to the brain. Gestational choriocarcinoma (GC) when metastasized to the brain has a higher morbidity and mortality but has been known to be a chemosensitive and radiosensitive lesion, and NGC is chemoresistant with an even worse prognosis. Currently, there is no consensus for treatment for metastatic NGC to the brain...

OBJECTIVE Trigeminal neuralgia is a debilitating pain disorder most often caused by arterial compression of the trigeminal nerve, although there are other etiologies. Microvascular decompression (MVD) remains the most definitive treatment for this disorder, with cure rates reported between 60% and 80%. Traditional MVD techniques involve a retrosigmoid craniotomy with placement of an inert foreign material, such as Teflon, between the nerve and compressive vessel. Recurrence of trigeminal neuralgia after MVD has been associated with vessel migration, adhesion formation, and arterial pulsation against the Teflon abutting the nerve...

OBJECTIVE Aneurysms of the middle cerebral artery (MCA) are still most often treated by clipping through standard craniotomy, but a longer hospital stay is one of the main drawbacks of this treatment. The authors developed a pterional keyhole clipping strategy for unruptured MCA aneurysms with the intention of minimizing hospital stay. In this paper, they report on their experience with this approach and analyze the long-term neurological and radiological outcomes. METHODS A total of 160 relatively small unruptured MCA aneurysms (mean 6...

OBJECTIVE Acute pain control after cranial surgery is challenging. Prior research has shown that patients experience inadequate pain control post-craniotomy. The use of oral medications is sometimes delayed because of postoperative nausea, and the use of narcotics can impair the evaluation of brain function and thus are used judiciously. Few nonnarcotic intravenous (IV) analgesics exist. The authors present the results of the first prospective study evaluating the use of IV acetaminophen in patients after elective craniotomy...

Deep-seated, subcortical tumors represent a surgical challenge. The traditional approach to these lesions involve large craniotomies, fixed retractor systems, and extensive white matter dissection, each with their own associated morbidity. We describe our experience with the use of tubular retractors for accessing these deep-seated lesions. Fifty consecutive patients operated on for an intra-axial brain tumor (both biopsies and resection) from January 2016 to December 2017 by a single surgeon using tubular retractors with exoscopic visualization were prospectively identified and included in this consecutive case series...

A 42-yr-old female presented with an olfactory groove meningioma causing progressive vision loss and anosmia. Given the size of the tumor, we opted for a 2-stage surgery: endoscopic endonasal approach (EEA) followed by a craniotomy. Stage I surgery was a transcribriform transplanum EEA using a binostril 4-hand/2 surgeons (ENT and neuro) technique, with the patient positioned supine with the head slightly turned to the right side and tilted to the left, fixed in a 3-pin head clamp, under imaging guidance, in which we drilled out all the affected skull base bone, devascularized and debulked the tumor...

RATIONALE: Meningioma is slow-growing benign neoplasm that derived from the meningothelial cells of the arachnoid mater, and it is the most common type of primary brain tumor. Although cases of extracranial metastatic meningioma have been reported previously, few cases have reported the concurrent occurrence of primary meningioma with intratumoral bleeding and lung metastases. Here we report a case of meningioma with concurrent intratumoral bleeding and lung metastases. PATIENT CONCERNS: The patient was admitted to our hospital with sudden left limb paralysis combined with complaints of headache and dizziness...

A male rhesus macaque with a cephalic chamber implant for neurophysiology recording presented with hemiparesis affecting the left thoracic and pelvic limbs at approximately 5 wk after craniotomy surgery. MRI indicated a 1×2-cm ovoid cerebrocortical cystic lesion immediately subjacent to the right hemisphere craniotomy and recording chamber. Transdural aspiration of sterile transudate and resultant decompression resolved the hemiparesis, and follow-up MRI at 1 mo indicated resolution of the lesion. Subsequently, necropsy at study end revealed a cerebrocortical foreign body composed of silicon...

Recurrent chemical meningitis from cyclic leakage of cyst content from a craniopharyngioma is a rare phenomenon. Here, we report a case of leaking cystic craniopharyngioma presenting with recurrent episodes of sterile meningitis, depression, and paranoia. The diagnosis after an initial craniotomy and exploration was hypophysitis. Signs and symptoms were not alleviated by puncture and biopsy of the tumour but they disappeared after complete resection with a final histological diagnosis of craniopharyngioma.

Intracranial lesions along the falx and tentorium often require exposure of a dural venous sinus. Craniotomies that cross a sinus should maximize exposure while minimizing the risk of sinus injury and provide a cosmetically appealing result with simple reconstruction techniques.  We describe the published techniques for exposing dural venous sinuses, and introduce a new technique for a single-piece craniotomy exposing the superior sagittal sinus or transverse sinus using drilled troughs. A review of the literature was performed to identify articles detailing operative techniques for craniotomies over dural venous sinuses...

Vestibular schwannoma (VS) is a brain tumour arising from Schwann cells that is typically closely associated with the vestibulocochlear nerve. Post-operative headaches (POH) are a potentially common complication of surgery for VS. Greatly differing rates of POH have previously been reported, particularly with different surgical approaches. The aim of this review is to identify and summarise the available peer-reviewed evidence on rates of POH following operative (or radiosurgery) treatment for VS, in addition to information about the treatment and prognosis of POH in these patients...

BACKGROUND: The endoscopic transorbital approach has been recently proposed for the surgical management of spheno-orbital lesions as an alternative to craniotomy surgeries. METHOD: We analyze the technical nuances and what we have changed as our experience increased after the first operations performed for 12 different spheno-orbital lesions. CONCLUSION: The endoscopic transorbital approach is useful for the treatment of selected spheno-orbital lesions and could represent an interesting option in experienced hands...

In Spring of 2012, the partially undressed and skeletonized remains of a homeless adult Hispanic male was found in a fairly open wooded area in Nebraska. The remains showed evidence of extensive pathologies, which included healed traumas and surgeries. Examination of the decedent's medical records revealed that he had a history of kidney and liver problems, alcohol abuse, several traumas including a major head injury that necessitated a craniotomy, and radiological features of neurocysticercosis. The autologous bone flap, which was replaced after the craniotomy, had resorbed significantly away from the edges of the injury...

Introduction: Idarucizumab is the first effective humanized monoclonal antibody fragment developed specifically as a reversal agent for dabigatran, a Direct Oral Anticoagulant. Despite recent trials demonstrating reversal of clinically relevant bleeding, there is a paucity of data on use outside the trial setting. This manuscript describes the use of Idarucizumab to reverse dabigatran in two patients presenting to the emergency department of a major tertiary hospital with acute traumatic subdural haematomas (SDH)...
