Abstract
BACKGROUND Cavernous malformations (CMs) originating from spinal nerve roots are rare but can present with rapidly progressing neurological deficits. Therefore, quick identification and treatment are essential. OBSERVATIONS The authors present the case of a 52-year-old male presenting with headaches and gait disturbance, found to have a CM of the C1 nerve root. The patient underwent successful suboccipital craniectomy and C1 laminectomy, with complete resection of the lesion, preservation of the cervical spinal nerve roots, and symptomatic improvement postoperatively. LESSONS This is the first presentation in the literature of a CM originating from the C1 nerve root. The authors show complete resection of the lesion with preservation of the C1 nerve root. Nerve root lesions usually show insidious symptomatic onset. Quick identification and resection are recommended to prevent permanent neurological disability. https://thejns.org/doi/10.3171/CASE2456.

[PMID: 38154230 PMCID: PMC10800712 DOI: 10.1016/j.ijscr.2023.109200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 12/19/2023] [Accepted: 12/20/2023] [Indexed: 12/30/2023] Open
Abstract
INTRODUCTION Cavernous malformation of the cauda equina is a rare neurosurgical condition. We sought to highlight one of these cases and its resultant diagnosis and management. Additionally, to recommend the need for raised clinical suspicion of these rare masses when an extramedullary lesion is noted on imaging. PRESENTATION OF CASE A 42-year-old female presented to our institution with a 9-month history of lower back pain. Her examination findings revealed a loss of right ankle jerk reflex. Magnetic resonance imaging (MRI) of her lumbosacral spine demonstrated an intradural, extramedullary tumor involving the cauda equina, at the L4/L5 level. The main differential diagnosis at this time was an ependymoma. An L4/5 laminectomy and resection of the cauda equina mass was scheduled. Intra-operatively, a mulberry - like mass was noted involving a single nerve root. A gross total resection was performed, with resolution of most of her symptoms. Histopathological diagnosis of a cavernous malformation was ascertained. DISCUSSION The accurate diagnosis of a cavernous malformation of the cauda equina was only suspected intra-operatively, following gross inspection. Cauda equina masses usually include myxopapillary ependymomas and schwannomas, making this vascular extramedullary lesion low on the possible differentials list. Very few cases have been published in modern literature. CONCLUSION Cavernous malformations of the cauda equina are an extremely uncommon, benign vascular malformation. These malformations have key characteristics on MRI that can aid its differentiation from other intradural lesions. However, because it is so rare, it does not usually make the list of differentials when considering likely extramedullary lesions.

Abstract
PURPOSE Clinical outcome of spinal cavernous malformation (SCM) varies because of its unclear natural history, and reliable prognostic prediction model for SCM patients is limited. The aim of the present study was to investigate potential factors that predict one-year neurological status in postoperative patients with SCM. METHODS This was a multicenter prospective observational study in consecutive patients with SCMs. SCMs treated microsurgically between January 2015 and January 2021 were included. Outcome was defined as the American Spinal Injury Association Impairment Scale (AIS) grade at one year after operation. Multivariable analyses were used to construct the best predictive model for patient outcomes. RESULTS We identified 268 eligible SCM patients. Neurological outcome had worsened from preoperative baseline in 51 patients (19.0%) at one year. In the multivariable logistic regression, the best predictive model for unfavorable outcome included symptom duration ≥ 26 months (95% CI 2.80-16.96, P < 0.001), size ≤ 5 mm (95% CI 1.43-13.50, P = 0.010), complete intramedullary (95% CI 1.69-8.14, P = 0.001), subarachnoid hemorrhage (95% CI 2.92-12.57, P < 0.001), AIS B (95% CI 1.91-40.93, P = 0.005) and AIS C (95% CI 1.12-14.54, P = 0.033). CONCLUSIONS Admission size of the lesion, morphology, symptom duration, AIS grade and the presence of subarachnoid hemorrhage were strong outcome predictors regarding prognostication of neurological outcome in postoperative patients with SCMs. A decision to surgically remove a symptomatic SCM should be justified by systematic analysis of all factors potentially affecting outcome.

Abstract
PURPOSE This study aimed to investigate the neurological outcome, trends and sequelae following surgical or conservative treatment of intramedullary spinal cord cavernous malformations (ISCCMs). METHODS A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome measure was the change in the neurological status after surgery or conservative management. A logistic regression analysis investigating prognostic factors related to outcome was also performed. RESULTS Twenty-one studies with 1091 patients in total were included, of which 1005 (92.1%) underwent surgical resection and 86 (7.9%) were treated conservatively. Gross total resection was achieved in 95.7% of the patients and partial resection in 4.3%. Most lesions (60.2%) were located in the thoracic spine and presented with motor (60.4%) and sensory deficits (59.7%). In the long term, surgical treatment resulted in an improved neurological status in 36.9% of the patients, in 55.8% it remained stable, and in 7.3% it deteriorated compared to the preoperative state. In the conservative cohort, 21.7% improved, 69.6% remained stable, and 8.7% deteriorated. Solitary lesions, duration of preoperative symptoms less than 3 months as well as an improved post-operative neurological status were predictors of a favourable long-term outcome. CONCLUSIONS Whenever feasible, symptomatic patients with ISCCM are recommended to undergo surgery within 3 months from symptom onset. Absence of multiple lesions and, most importantly, post-operative symptom improvement foresee a favourable long-term outcome. Further research is warranted to discern the role of conservative treatment in symptomatic patients.

Imaging characteristics, misdiagnosis and microsurgical outcomes of patients with spinal dural arteriovenous fistula: a retrospective study of 32 patients. ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:832. [PMID: 36034988 PMCID: PMC9403910 DOI: 10.21037/atm-22-3568] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Accepted: 08/04/2022] [Indexed: 11/06/2022]
Abstract
Background Spinal dural arteriovenous fistula (SDAVF) is an extremely rare spinal vascular malformation. As SDAVF exhibits no specific clinical manifestations nor diverse imaging results, it is easily misdiagnosed, resulting in delayed treatment and irreversible neurological damage. Most patients were initially misdiagnosed, but there were few reports on reducing misdiagnosis. Methods A total of 32 consecutive patients, who presented to our institution (Shanghai Deji Hospital) with SDAVF between June 2013 and January 2016 were retrospectively analyzed. Data were collected on demographics, clinical presentation, imaging findings, follow-up, and clinical outcomes. The Aminoff-Logue scale (ALS) was used to assess clinical outcomes. Results Of the 32 enrolled patients (3 females, mean age 59.1±3.8 years), 23 patients (71.9%) were misdiagnosed as acute myelitis (11 patients), intramedullary tumors (6 patients), lumbar disc herniation (4 patients), and other conditions (2 patients). All patients underwent surgical procedures under electrophysiological monitoring. Fistulas were found in all 32 patients and were successfully occluded. The mean follow-up period was 19.22±8.21 months (ranging from 2 weeks to 30 months). One year later, 20 patients underwent magnetic resonance imaging (MRI), and 14 showed no T2 edema, and the edema was relieved in 6 patients. A total of 10 patients underwent enhancement MRI and no enhancement signs were detected. Among the 27 patients with long-time follow-up, the fistula had no residual or recurrence, 21 patients showed decreased ALS scores (P<0.05). Six patients exhibited nonsignificant improvement. No aggravating patient was found. Prognosis differed significantly between patients with ALS <6 and those with ALS ≥6 (P<0.05). Conclusions Spinal angiography should be performed with full intubation, and microcatheter angiography can reduce misdiagnosis. SDAVF must be differentiated from acute myelitis, intramedullary tumor, and other spinal vascular malformations. Microsurgical treatment is effective with a low recurrence rate.

Abstract
PURPOSE Pediatric intramedullary spinal cord cavernous malformation (ISCM) is a rare vascular disease with unclear natural history and long-term outcomes. We aim to determine the demographics, hemorrhagic risk, and long-term outcomes of this rare entity. METHODS A retrospective review of clinical data and treatment outcomes of pediatric patients treated with ISCM in our institution from 3/2000 to 3/2017 was conducted. In addition, we performed a systematic review of the literature on pediatric ISCM. RESULTS Eighteen consecutive pediatric patients were included, with an average age of 12.9 ± 4.7 years (range: 4-18 years) and 66.7% being male. Locations were equally distributed in cervical and thoracic segments, with mean extension of 1.3 ± 0.7 segments. Clinical manifestation included extremity weakness (n = 15, 83.3%), pain (n = 10, 55.6%), sensory disorders (n = 8, 44.4%), sphincter disturbance (n = 6, 33.3%), muscular atrophy (n = 3, 16.7%), and spinal deformity (n = 1, 5.6%). Most patients presented with acute symptoms (n = 11, 61.1%), and 7 (38.9%) of them had severe neurological deficits. The annual retrospective hemorrhagic risk was 7.7 per patient-year. Two patients received conservative management, with one improved neurologically and the other remained unchanged. Total resection was achieved in 12 (75%) of the 16 surgical cases, with 8 patients (50%) improved their clinical outcomes, 7 patients (43.8%) remained unchanged, and 1 (6.3%) worsened. During follow-up, one patient had relapse of ISCM. CONCLUSION Pediatric ISCM appears to have higher hemorrhage risk than their adult counterparts, and they can benefit from surgery whether in the acute phase of neurological deterioration or after clinical recuperation.

Abstract
Objectives We present a case series of spinal cord cavernous malformations (SCCMs) to describe clinical presentation and outcomes of both surgical and conservative management. Methods The clinical courses of patients diagnosed with SCCMs at our institution were retrospectively reviewed. Neurologic symptoms were evaluated using the Modified McCormick Scale. Results A total of 18 patients were identified. Five patients (27.8%) presented with acute onset bleeding, 4 of whom underwent immediate surgical resection. Thirteen patients (72.2%) were initially managed conservatively. Eight patients (38.9%) developed a hemorrhage during follow-up, and 8 (38.9%) required surgical resection due to bleeding or neurological worsening. The mean (range) duration from primary symptoms to subsequent hemorrhage or deterioration of symptoms was 1.42 (range: 0.25–4.33) years. The mean duration from primary symptoms to surgery was 2.10 (range: 0.25–5.0) years. No patients experienced subsequent hemorrhage after surgical resection. Eleven patients (84.6%) in the surgery group showed improved neurological status, and 2 patients (15.4%) remained unchanged. The annualized subsequent hemorrhage risk was 3.7%. Patients in the immediate surgical group had a significantly larger lesion compared with those in the conservative group. There was significance between the worst Modified McCormick Scale grades at the time of debilitating symptoms and the length of hemorrhage, but not the size of the lesion. Conclusions Surgery for SCCMs resulted in no recurrence of hemorrhage or exacerbation of neurological symptoms, and should be considered for patients who experienced acute onset of hemorrhage or debilitating symptoms during follow-up.

Abstract
OBJECTIVE Intramedullary cavernous hemangioma (CH) is a rare vascular lesion that is mainly characterized by the sudden onset of hemorrhage in young, asymptomatic patients, who then experience serious neurological deterioration. Despite the severity of this condition, the therapeutic approach and timing of intervention for CH remain matters of debate. The aim of this study was to evaluate the clinical characteristics of CH patients before and after surgery and to identify prognostic indicators that affect neurological function in these patients. METHODS This single-center retrospective study included 66 patients who were treated for intramedullary CH. Among them, 57 underwent surgery and 9 patients received conservative treatment. The authors collected demographic, symptomology, imaging, neurological, and surgical data. Univariate and multivariate logistic regression analyses were performed to identify the prognostic indicators for neurological function. RESULTS When comparing patients with stable and unstable gait prior to surgery, patients with unstable gait had a higher frequency of hemorrhagic episodes (52.4% vs 19.4%, p = 0.010), as assessed by the modified McCormick Scale. The lesion was significantly smaller in patients who underwent conservative treatment compared with surgery (2.5 ± 1.5 mm vs 5.9 ± 4.1 mm, respectively; p = 0.024). Overall, the patients experienced significant neurological recovery after surgery, but a worse preoperative neurological status was identified as an indicator affecting surgical outcomes by multivariate analysis (OR 10.77, 95% CI 2.88–40.36, p < 0.001). In addition, a larger lesion size was significantly associated with poor functional recovery in patients who had an unstable gait prior to surgery (8.6 ± 4.5 mm vs 3.5 ± 1.6 mm, p = 0.011). CONCLUSIONS Once a hemorrhage occurs, surgical intervention should be considered to avoid recurrence of the bleeding and further neurological injury. In contrast, if the patients with larger lesion presented with worse preoperative functional status, surgical intervention could have a risk for aggravating the functional deficiencies by damaging the thinning cord parenchyma. Conservative treatment may be selected if the lesion is small, but regular neurological examination by MRI is needed for assessment of a change in lesion size and for detection of functional deterioration.

Abstract
OBJECTIVE Optimal surgical strategies for intramedullary spinal cord cavernous malformations (ISCCMs) are not optimized and remain problematic. In this study the authors identify rational surgical strategies for ISCCMs and predictors of outcomes after resection. METHODS A single-center study was performed with 219 consecutive surgically treated patients who presented from 2002 to 2017 and were analyzed retrospectively. The American Spinal Injury Association (ASIA) Impairment Scale was used to evaluate neurological functions. Patient characteristics, surgical approaches, and immediate and long-term postoperative outcomes were identified. RESULTS The average ISCCM size was 10.5 mm. The spinal level affected was cervical in 24.8% of patients, thoracic in 73.4%, and lumbar in 1.8%. The locations of the lesions in the horizontal plane were 30.4% ventral, 41.6% dorsal, and 28.0% central. Of the 214 patients included in the cohort for operative evaluation, 62.6% had superficially located lesions, while 37.4% were embedded. Gross-total resection was achieved in 98.1% of patients. The immediate postoperative neurological condition worsened in 10.3% of the patients. Multivariate logistic regression identified mild preoperative function (p = 0.014, odds ratio [OR] 4.5, 95% confidence interval [CI] 1.4-14.8) and thoracolumbar-level lesions (p = 0.01, OR 15.7, 95% CI 1.9-130.2) as independent predictors of worsening. The mean follow-up duration in 187 patients was 45.9 months. Of these patients, 63.1% were stable, 33.2% improved, and 3.7% worsened. Favorable outcomes were observed in 86.1% of patients during long-term follow-up and were significantly associated with preoperative mild neurological and disability status (p = 0.000) and cervically located lesions (p = 0.009). The depths of the lesions were associated with worse long-term outcomes (p = 0.001), and performing myelotomy directly through a yellowish abnormal surface in moderate-depth lesions was an independent predictor of worsening (p = 0.023, OR 35.3, 95% CI 1.6-756.3). CONCLUSIONS Resection performed with an individualized surgical approach remains the primary therapeutic option in ISCCMs. Performing surgery in patients with mild symptoms at the thoracolumbar level and embedded located lesions requires more discretion.

Abstract
OBJECTIVE There is a paucity of literature investigating the clinical course of patients with spinal intramedullary cavernous malformations (ISCMs). We present a large case series of ISCMs to describe clinical presentation, natural history and outcomes of both surgical and conservative management. METHODS We retrospectively reviewed the clinical course of patients diagnosed with ISCMs at our institution between 1995 and 2016. Haemorrhage was defined as clinical worsening in tandem with imaging changes visualised on follow-up MRI. Outcomes assessed included neurological status and annual haemorrhage rates. RESULTS A total of 107 patients met inclusion criteria. Follow-up data were available for 85 patients. While 21 (24.7%) patients underwent immediate surgical resection, 64 (75.3%) were initially managed conservatively. Among this latter group, 16 (25.0%) suffered a haemorrhage during follow-up and 11 (17.2%) required surgical resection due to interval bleeding or neurological worsening. The overall annual risk of haemorrhage was 5.5% per person year. The rate among patients who were symptomatic and asymptomatic on presentation was 9.5% and 0.8%, respectively. Median time to haemorrhage was 2.3 years (0.1-12.3). Univariate analysis identified higher ISCM size (p=0.024), history of prior haemorrhage (p=0.013) and presence of symptoms (p=0.003) as risk factors for subsequent haemorrhage. Multivariable proportional hazards analysis revealed presence of symptoms to be independently associated with haemorrhage during follow-up (HR 9.39, CI 1.86 to 170.8, p=0.013). CONCLUSION Large, symptomatic ISCMs appear to be at increased risk for subsequent haemorrhage. Surgery may be considered in such lesions to prevent rebleeding and subsequent neurological worsening.

Abstract
Aim We report the preoperative and postoperative findings and also neurological follow-up results from 10 spinal cavernoma patients treated in our clinic. Several representative cases are presented in terms of clinical features, imaging results, and surgical outcomes. Material and methods The data were retrospectively collected from patients' files in the hospital records and sorted with regards to clinical presentation, radiologic features, and operative findings. Patients received spinal MRI scans for the diagnosis of spinal cavernomas (SC) and postsurgical evaluation. Clinical presentation was evaluated via Ogilvy classification and symptoms were checked preoperatively and postoperatively at third month and first year using McCormick scale. Primary treatment was microsurgical operation aiming a gross total lesion resection. Results 10 spinal cavernoma patients between the ages 30 and 63 were treated. Six (60%) of the patients were diagnosed with cervical and four (40%) others were diagnosed with thoracic SC. Among the patient group, mean preoperative Ogilvy classification score was 2.3 ± 0.7.8 and McCormick score was 1.9 ± 0.7. There was no residual mass or relapse after surgery. One patient developed surgery-related left hemiparesis, which was normalized at 1 year follow-up. Conclusion Patients must be diagnosed with MRI since it is nowadays a gold standard. Preoperative and postoperative scores are important in evaluating the patients' condition and improvement. The results from our patient series also reinforce the notion that immediate surgery should be the preferred treatment method for cavernomas. Intraoperative neurophysiologic monitarization should assist the surgery in order to prevent complications. In conclusion, microsurgery is a gold standard method that we recommend for cases of cavernomas, which will not recur if gross total resection is achieved.

Abstract
Spinal cavernous malformations are rare intramedullary vascular lesions of the central nervous system. Most are located in the thoracic spine. Patients present with either acute neurologic deficit or gradual deterioration. Weakness is the most common presenting symptom. The annual hemorrhage risk is 2.1%. Diagnosis is made by magnetic resonance imaging as these lesions are occult on angiography. Surgical removal is indicated in patients with hemorrhage and neurologic deficit. All lesions are approached posteriorly by laminectomy. Dorsal cavernous malformations are exposed by focused laminectomy of the level or levels overlying the lesion with minimally facet violation. Ventral and lateral lesions are approached by laminectomy including a level above and level below as well as unilateral radical facetectomy. After midline dural opening, the dentate ligament is divided and retracted to allow up to 90° of rotation of the spinal cord. Microsurgical treatment is associated with 42% symptom improvement and 50% symptom stabilization. Postoperative worsening is associated with longer preoperative duration of symptoms. Therefore we recommend consideration of early surgery for cavernous malformation removal in patients with symptoms attributable to the lesion.

Abstract
BACKGROUND Primary spinal tumors are rare. Symptoms depend on the size and location of the tumor. CASE DESCRIPTION A patient presented with a rare clinical finding, Brown-Séquard syndrome. The symptoms were caused by an extramedullary tumor compressing on the thoracic spinal cord. Pathologic examination showed cavernous hemangioma with growth both intradurally and extradurally. CONCLUSIONS This is an extremely rare finding; to our knowledge, only 1 case report has been published before in which a spinal cavernous hemangioma had intradural and extradural growth. The clinical symptoms of Brown-Séquard syndrome have not been described before in the findings of spinal cavernous hemangiomas.

Abstract
OBJECT Intramedullary spinal cavernoma (ISC) is a rare entity and accounts for approximately 5%-12% of all spinal vascular pathologies. The purpose of the present study was to examine the influence of clinical presentation, localization, and different surgical approaches on long-term outcome in patients treated for ISC. METHODS The authors performed a retrospective single-center study of 48 cases of ISC treated microsurgically over the past 28 years. Analyzed factors included preoperative clinical history, microsurgical strategies, neurological outcome (American Spinal Injury Association [ASIA] grade, Epstein and Cooper grade), and the occurrence of postoperative spinal ataxia. Univariate analysis was performed to identify factors influencing long-term outcome. RESULTS Preoperatively, 18.8% of all patients experienced a slow, progressive decline in neurological function and 33.3% suffered repetitive episodes of acute neurological deterioration over a time frame of months to years. Moreover, 16.7% noted the sudden onset of a severe neurological deficit, whereas 25% experienced the sudden onset of symptoms with a subsequent gradually progressive decline in neurological function. On long-term follow-up after treatment (mean ± SD, 79.3 ± 35.2 months), 70.8% of patients showed no change in neurological function, 6.3% suffered from a decline, and 22.9% improved neurologically. Thoracolumbar localization (p = 0.043), low preoperative Epstein and Cooper grade for the lower extremities (p < 0.001), and a low preoperative ASIA grade (p < 0.001) were identified as factors associated with an unfavorable outcome (ASIA Grade A-C). The rate of spinal ataxia related to surgical approach was 16.7%. CONCLUSION Postoperative neurological function in ISC patients is determined by the preoperative neurological status. On long-term follow-up after microsurgical treatment, 93.7% of patients presented with a stable or improved condition (ASIA grade); thus, definite microsurgical treatment should be considered as long as patients present with only mild symptoms after the diagnosis of symptomatic ISC.

Abstract
Object
Information pertaining to the natural history of intramedullary spinal cord cavernous malformations (ISCCMs) and patient outcomes after surgery is scarce. To evaluate factors associated with favorable outcomes for patients with surgically and conservatively managed ISCCMs, the authors performed a systematic review and metaanalysis of the literature. In addition, they included their single-center series of ISCCMs.
Methods
The authors searched MEDLINE, EMBASE, CINAHL, Google Scholar, and The Cochrane Library for studies published through June 2013 that reported cases of ISCCMs. Data from all eligible studies were used to examine the epidemiology, clinical features, and neurological outcomes of patients with surgically managed and conservatively treated ISCCMs. To evaluate several variables as predictors of favorable neurological outcomes, the authors conducted a meta-analysis of individual patient data and performed univariate and multivariate logistic regression analyses. Variables included patient age, patient sex, lesion spinal level, lesion size, cerebral cavernomas, family history of cavernous malformations, clinical course, presenting symptoms, treatment strategy (operative or conservative), symptom duration, surgical approach, spinal location, and extent of resection. In addition, they performed a meta-analysis to determine a pooled estimate of the annual hemorrhage rate of ISCCMs.
Results
Eligibility criteria were met by 40 studies, totaling 632 patients, including the authors' institutional series of 24 patients. Mean patient age was 39.1 years (range 2–80 years), and the male-to-female ratio was 1.1:1. Spinal levels of cavernomas were cervical (38%), cervicothoracic (2.4%), thoracic (55.2%), thoracolumbar (0.6%), lumbar (2.1%), and conus medullaris (1.7%). Average cavernoma size was 9.2 mm. Associated cerebral cavernomas occurred in 16.5% of patients, and a family history of cavernous malformation was found for 11.9% of evaluated patients. Clinical course was acute with stepwise progression for 45.4% of patients and slowly progressive for 54.6%. Symptoms were motor (60.5%), sensory (57.8%), pain (33.8%), bladder and/or bowel (23.6%), respiratory distress (0.5%), or absent (asymptomatic; 0.9%). The calculated pooled annual rate of hemorrhage was 2.1% (95% CI 1.3%–3.3%). Most (89.9%) patients underwent resection, and 10.1% underwent conservative management (observation). Outcomes were better for those who underwent resection than for those who underwent conservative management (OR 2.79, 95% CI 1.46–5.33, p = 0.002). A positive correlation with improved neurological outcomes was found for resection within 3 months of symptom onset (OR 2.11, 95% CI 1.31–3.41, p = 0.002), hemilaminectomy approach (OR 3.20, 95% CI 1.16–8.86, p = 0.03), and gross-total resection (OR 3.61, 95% CI 1.24–10.52, p = 0.02). Better outcomes were predicted by an acute clinical course (OR 1.72, 95% CI 1.10–2.68, p = 0.02) and motor symptoms (OR 1.76, 95% CI 1.08–2.86, p = 0.02); poor neurological recovery was predicted by sensory symptoms (OR 0.58, 95% CI 0.35–0.98, p = 0.04). Rates of neurological improvement after resection were no higher for patients with superficial ISCCMs than for those with deep-seated ISCCMs (OR 1.36, 95% CI 0.71–2.60, p = 0.36).
Conclusions
Intramedullary spinal cord cavernous malformations tend to be clinically progressive. The authors' findings support an operative management plan for patients with a symptomatic ISCCM. Surgical goals include gross-total resection through a more minimally invasive hemilaminectomy approach within 3 months of presentation.
