RESUMEN
OBJECTIVE: Conus region lumbosacral lipomas (LSLs) are highly heterogeneous in their morphology, clinical presentation, and outcome, with an incompletely understood natural history and often treacherous surgical anatomy. This systematic review aims to critically evaluate and assess the strength of the current LSL evidence base to guide management strategies. METHODS: According to a systematic review following PRISMA guidelines, a search was conducted using the key term "lumbosacral lipoma" across MEDLINE (OVID), Embase, Cochrane Library, and PubMed databases from January 1951 to April 2021. All studies containing ten or more paediatric conus lipomas were included. Data heterogeneity and bias were assessed. RESULTS: A total of 13 studies were included, containing 913 LSLs (predominantly transitional type-58.5%). Two-thirds (67.5%) of all patients (treated and non-treated) remained clinically stable and 17.6% deteriorated. Neuropathic bladder was present in 8.6% at final follow-up. Of patients managed surgically, near-total resection vs. subtotal resection deterioration-free survival rates were 77.2-98.4% and 10-67% respectively. 4.5% (0.0-27.3%) required re-do untethering surgery. Outcomes varied according to lipoma type. Most publications contained heterogeneous populations and used variable terminology. There was a lack of consistency in reported outcomes. CONCLUSION: Amongst published series, there is wide variability in patient factors such as lipoma type, patient age, and methods of (particularly urological) assessment. Currently, there is insufficient evidence base upon which to make clear recommendations for the management of children with LSL. There is an imperative for neurosurgeons, neuroradiologists, and urologists to collaborate to better standardise the terminology, assessment tools, and surgical interventions for this challenging group of conditions.

BACKGROUND: Brain biopsies are required to establish a definitive histological diagnosis for brain lesions that have been identified on imaging in order to guide further treatment for patients. OBJECTIVE: Various navigation systems are in use but little up to date evidence is available regarding the safety and accuracy of a frameless, electromagnetic technique to target brain lesions. METHODS: Data was collected retrospectively on all patients that had brain biopsies at our institution from 01/01/2010 to 31/12/2017. Operation notes, neuropathology reports, and clinical notes on electronic patient record were used to determine whether biopsy of adequate identifiable abnormal tissue was achieved, whether a definitive diagnosis was established, any adverse events occurred, and if a repeat biopsy was carried out. RESULTS: Three hundred seventy-one AxiEM (Medtronic, Minneapolis, USA)-guided brain tumor biopsies were performed in this 8-year period. Three hundred forty-nine (94.07%) procedures provided definitive tissue diagnosis, 22 (5.93%) were non diagnostic; in 6 cases (1.62%), repeat biopsy was performed and adverse events which caused clinical compromise were observed in 4 patients (1.08%). CONCLUSIONS: The AxiEM is a fast, effective, and safe frameless and pinless neuronavigational system. It offers a high degree of accuracy required for the establishment of a definitive diagnosis, permitting optimal further treatment, and thus improving patient outcomes.

We present a case of a giant ovarian cyst in a 20-year-old woman who presented atypically at our Emergency Department with left-sided back pain followed by acute left leg swelling. Blood tests showed significantly raised C-Reactive Protein and D-Dimer. CT-Abdomen-Pelvis demonstrated a large mass in the region of the right ovary with suspicious heterogeneous filling defects in the left external iliac vein, confirmed as a left-sided deep-vein thrombosis on ultrasound Doppler. MRI revealed the lesion to be cystic and the deep venous thrombosis was treated with twice-daily Clexane. Prior to removal of the cyst, an Inferior Vena Cava Filter was placed to reduce thromboembolic risk. The cyst was resected without complication and the postoperative period was uneventful. This case occurred while face-to-face services were limited by COVID-19 and illustrates the need for robust systemic measures to safeguard patients against the emergency sequelae of insidious gynaecological pathology.

BACKGROUND: Cauda equina syndrome (CES) is rare neurosurgical emergency requiring emergent surgical decompression to prevent bladder, bowel, and sexual dysfunction that can have significant impact on quality of life. There is a paucity of data relating to the prevalence of these long-term complications. OBJECTIVE: The aim of this observational study was to evaluate the long-term prevalence of CES-related bladder, bowel, and sexual dysfunction and impact on quality of life to inform service provision. METHODS: Participants were selected through coding of operative records of patients who underwent lumbar decompression for CES secondary to a herniated intervertebral disc at two large UK neurosurgical departments between 2011 and 2015 inclusive. A telephone-based survey including both validated and modified tools was used to collect data pertaining to bladder, bowel, and sexual function and impact on quality of life both before development of CES and at the time of the survey, at least 1 year postoperatively. RESULTS: Of 135 patients contacted, 71 (42 male, 29 female) responded. Post-CES compared to pre-CES, there was higher prevalence and significant intrarespondent deterioration of bowel dysfunction, bladder dysfunction, perception of bladder function, sexual function, effect of back pain on sex life, and activities of daily living/quality of life (p < .0001 for all). Significant differences in individual questions pre-CES versus post-CES were also found. CONCLUSION: We show high prevalence of long-term bowel, bladder, and sexual dysfunction post-CES, with functional and psychosocial consequences. Our results demonstrate the need for preoperative information and subsequent screening and long-term multidisciplinary support for these complications.
