{"title":"When is the radiology report of posterior fossa containing cyst/cystic-like CSF collection of clinical or surgical significance?","authors":"Jeffrey J Quezada, Marvin D Nelson, J Gordon McComb","doi":"10.3171/2024.6.PEDS2458","DOIUrl":"10.3171/2024.6.PEDS2458","url":null,"abstract":"<p><strong>Objective: </strong>The nomenclature characterizing posterior fossa (PF) extraventricular (EV) CSF collections in radiological reports can be quite variable, leading to uncertainty about the subsequent clinical course that may result in multiple follow-up imaging studies that may not be needed and occasionally to operative intervention that is not warranted. The important factor is the mass effect of the PF EV CSF collection on adjacent structures, the presence of hydrocephalus, and the likelihood of the CSF collection increasing in size over time.</p><p><strong>Methods: </strong>The authors respectively reviewed the imaging database at Children's Hospital Los Angeles to identify all radiological reports from 2000 to 2015 indicating the presence of an EV CSF collection in the PF that was characterized as containing an arachnoid cyst, being cystic, or being an abnormal CSF collection.</p><p><strong>Results: </strong>Of the 332 reports in 65 patients, the PF EV CSF collection was described as an arachnoid cyst or cystic in 306 with 20 different terms being used. In those patients who underwent multiple imaging studies, the PF EV CSF collection was often described differently in each report. Of this group, 47 (72%) patients did not undergo PF surgery. Eighteen (28%) patients did undergo PF surgery, of whom 14 had both hydrocephalus and brainstem displacement, 2 had brainstem displacement but no hydrocephalus, and 2 had neither brainstem displacement nor hydrocephalus and in retrospect did not benefit from PF surgery.</p><p><strong>Conclusions: </strong>The terminology in radiology reports describing EV PF CSF collections is variable, is inconsistent, and does not correlate well with clinical management or the need for PF surgery. Significant brainstem displacement and hydrocephalus in the presence of EV PF CSF collection is highly correlated with the need for PF surgery. The incidence of a PF EV CSF collection increasing to become symptomatic becomes more remote the older the patient is at the time of diagnosis as compared with those that occur mainly in infancy. There are true EV CSF cysts in the PF, but the ones that are of consequence are those that exert pressure on the brainstem, obstruct CSF flow, or both. Calling any increased amount of CSF in the PF a \"cyst\" or \"cystic\" can cause uncertainty, leading to one or more subsequent imaging studies or, in rare cases, unwarranted operative intervention.</p>","PeriodicalId":16549,"journal":{"name":"Journal of neurosurgery.

{"title":"Reduction cranioplasty for hydrocephalic macrocephaly: a systematic review of surgical outcomes.","authors":"Steven P Moura, Alexandra D Center, Manasa Kalluri, Jessica Blum, Ellen C Shaffrey, Samuel Lee, Jinggang J Ng, Bermans J Iskandar, Catharine B Garland, Daniel Y Cho","doi":"10.3171/2024.4.PEDS23486","DOIUrl":"10.3171/2024.4.PEDS23486","url":null,"abstract":"<p><strong>Objective: </strong>Hydrocephalic macrocephaly can result in poor psychosocial development, positioning difficulties, skin breakdown, and poor cosmesis. Although reduction cranioplasty can address these sequelae, the postoperative outcomes, complications, and mortality risk of reduction cranioplasty are not well understood given the rarity of hydrocephalic macrocephaly. Therefore, the primary objective of this systematic review was to evaluate the surgical outcomes of reduction cranioplasty for the treatment of hydrocephalic macrocephaly.</p><p><strong>Methods: </strong>A systematic review was performed using the PubMed, Scopus, and Web of Science databases while following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent reviewers screened 350 studies; 27 studies reporting surgical outcomes on reduction cranioplasty for hydrocephalic macrocephaly met inclusion criteria. Data on study design, patient demographics, operative details, and surgical outcomes were collected.</p><p><strong>Results: </strong>There were 65 reduction cranioplasties among the 27 included studies. Eighteen (66.7%) studies presented level V evidence, 7 (25.9%) presented level IV evidence, and 2 (7.4%) presented level III evidence. Following reduction cranioplasty, there was improvement in postoperative head positioning in 23 (85.2%) studies, improvement in postoperative cosmesis in 22 (81.5%) studies, and improvement in global postoperative neurological functioning in 20 (74.1%) studies. The median estimated blood loss was 633 mL (range 20-2600 mL). Shunt revisions were the most common complication, reported in 9 (47.4%) of the 19 studies assessing complications. Of the 65 patients, there was a mortality rate of 6.2% (n = 4).</p><p><strong>Conclusions: </strong>The majority of the included studies reported improvement in head size, head positioning, cranial cosmesis, and global neurological functioning following reduction cranioplasty for hydrocephalic macrocephaly. However, the prevalence of lower-level evidence, risk of blood loss, complications, and mortality indicates the need for a serious discussion of surgical indication, an experienced team, and thorough perioperative planning to perform these complex surgeries.</p>","PeriodicalId":16549,"journal":{"name":"Journal of neurosurgery.
