Academic metrics can be used to compare the productivity of researchers. We aimed to use a variety of bibliometric parameters to assess the productivity of neurosurgeons working in the United Kingdom. ⋯ This study details the academic impact of United Kingdom-based neurosurgeons through the analysis of a number of citation metrics. It provides a benchmark bibliometric profile and we advocate future comparative assessments as a means to assess impact of and guide academic policy.

Case Reports
Cerebellar enterogenous cyst with atypical appearance and pathological findings: a case report.
Intracranial enterogenous cysts are rare and occur mainly in the posterior fossa. These cysts are usually extra-axial, midline, anterior to the brainstem, or at the cerebellopontine angle. Intracranial intra-axial enterogenous cysts are extremely rare. We report a case of an intra-axial cerebellar enterogenous cyst in which diagnosis was difficult because the lesion resembled an arachnoid cyst in appearance and showed atypical pathologic findings. ⋯ The diagnosis of enterogenous cyst is based mainly on histologic findings, because characteristic findings on neuroimaging have not been defined. Although total resection of enterogenous cysts is recommended in general, partial resection while ensuring the cyst communicates adequately with the surrounding cerebrospinal fluid space with or without a shunt procedure may be useful if the cyst is adherent to surrounding neurovascular structures.

Decompressive craniectomy is an established treatment for malignant intracranial hypertension. Cranioplasty is performed once cerebral swelling has resolved. Complications include infection, postoperative fluid collections, hematoma, reoperation, and seizures. Our experience using a double layer technique during craniectomy with a collagen matrix onlay dural substitute and expanded polytetrafluoroethylene for antiadhesive properties during cranioplasty was reviewed. ⋯ Our dual layer closure technique at time of decompressive craniectomy carries a similar reduction in operative time and estimated blood loss when compared with cranioplasty series with other antiadhesives present. The technique described enables easy dissection of the musculocutaneous flap from the dural plane during cranioplasty and increases the safety of the operation.

Case Reports
Delayed deterioration in isolated traumatic subarachnoid hemorrhage Report of two cases.
Isolated traumatic subarachnoid hemorrhage (SAH) in association with mild traumatic brain injury is considered to be a less severe finding that is not likely to require surgical intervention. No previous reports have described cases warranting craniotomy for isolated traumatic SAH by itself. ⋯ Isolated traumatic SAH seen in the basal cistern and Sylvian fissure carries a risk of late deterioration. A possible cause of hematoma expansion is abruption of a perforating branch arising from the MCA at the time of head injury. When hematoma expansion is identified, surgical evacuation of the hematoma is indicated. Surgical evacuation should be safely performed with the knowledge of the point of bleeding in such patients.
