A case of spontaneous basal ganglia hemorrhage with contralateral extension utilizing the canal of Gratiolet.

BACKGROUND: Intracranial hemorrhage accounts for 10-20% of stroke etiologies annually. Basal ganglia is the most common site for intracranial hemorrhage accounting for 50% of all cases. Bilateral spontaneous basal ganglia hemorrhages (BGH) are rare with few reported cases. CASE PRESENTATION: We report an unusual case of a 69-year-old female who presented with a spontaneous bilateral basal ganglia hemorrhage secondary to a right BGH with contralateral extension through the anterior commissure (AC) utilizing the Canal of Gratiolet. Clinical course and imaging findings are discussed. CONCLUSIONS: To our knowledge, this is the first case to specifically detail the extension of spontaneous hemorrhage across the AC via the Canal of Gratiolet, and imaging findings provide a novel depiction of AC anatomy and fiber distribution in a clinical context. These findings may explain the mechanism behind this rare clinical entity.

Good functional outcome following bilateral external capsule hemorrhage mimicking bilateral basal ganglia hemorrhage in a coma patient.

Simultaneous spontaneous bilateral external capsule hemorrhage is a rare clinical entity with extremely poor outcome. However, knowledge on the effective management of this fatal disease is limited. Herein,we described a case of a 42-year-old man with acute coma and quadriplegia as well as respiratory failure related to the disease. The patient underwent minimally invasive surgery plus local thrombolysis. Consequently, he recovered with satisfactory neurological function recovery on the 180th day of follow-up.

Spontaneous Bilateral Basal Ganglia Haemorrhage Secondary to Methanol Poisoning.

Methanol toxicity remains as major problem in the medical field.[1],[2],[3] With its active metabolite, formic acid often leads to severe metabolic acidosis and to some extend brain damaged.[4],[5],[6] We are reporting a case of brain hemorrhage at the right external capsule and left basal ganglia with mass effect and obstructive hydrocephalus in a methanol poisoning patient. A confused 29-year-old gentleman was brought into hospital. Initial investigation showed severe metabolic acidosis with raised anion gap. Initial brain CT scan was normal. Subsequently, serum methanol was reported to be high (112 mg/dL). Intravenous (IV) ethanol 10% was given without any delayed. As there was no improvement in his consciousness level, a repeat brain CT was performed and it showed multiple cerebral hemorrhage with obstructive hydrocephalus. Hence, clinicians should have high index of suspicion for cerebral hemorrhage in a patient with methanol toxicity, who presented with altered mental status and severe metabolic acidosis.

Application of neuroendoscopic surgery in treatment of hypertensive basal ganglia hemorrhage. / Aplicación de la neurocirugía endoscópica en el tratamiento de las hemorragias hipertensivas en los ganglios basales.

INTRODUCTION: The influence of Application of neuroendoscopic surgery in treatment of hypertensive basal ganglia hemorrhage remains largely unknown. AIM: To compare the clinical efficacy of minimally invasive neuroendoscopic surgery (NES) and small bone window craniotomy (SBWC) microsurgery on the treatment of patients with hypertensive basal ganglia hemorrhage (HBGH). PATIENTS AND METHODS: The clinical data of 174 HBGH patients treated in our hospital from January 2018 to September 2020 were retrospectively analyzed. They were divided into minimally invasive NES group (n = 90) and SBWC microsurgery group (n = 84). Their operation time, hematoma clearance rate, rebleeding and prognosis were compared. RESULTS: In minimally invasive NES group, the operation time and intraoperative hemostasis time were significantly shorter, and the intraoperative blood loss was significantly less than those in SBWC microsurgery group (p menor de 0.001). The preoperative Glasgow coma scale (GCS) score was 8.64 ± 1.04 points and 8.68 ± 1.02 points respectively in minimally invasive NES group and SBWC microsurgery group (p mayor de 0.05). At 24 h after operation, the GCS score in minimally invasive NES group rose to 12.89 ± 1.56 points, and it had a significant difference from that in SBWC microsurgery group (11.18 ± 1.14 points, p menor de 0.001). The volume of brain edema was 11.82 ± 3.25 mL in minimally invasive NES group and 18.89 ± 3.15 mL in SBWC microsurgery group (p menor de 0.001). In minimally invasive NES group, the clearance of hematoma was superior to that in SBWC microsurgery group, and the prognosis was also better than that in SBWC microsurgery group. CONCLUSIONS: Minimally invasive NES has better efficacy than SBWC microsurgery in the treatment of HBGH.

TITLE: Aplicación de la neurocirugía endoscópica en el tratamiento de las hemorragias hipertensivas en los ganglios basales.Introducción. La relevancia de la neurocirugía endoscópica en el tratamiento de las hemorragias hipertensivas de los ganglios basales no se conoce en buena medida. Objetivo. Comparar la eficacia clínica de la neurocirugía endoscópica mínimamente invasiva con la de la microcirugía con craneotomía de ventana pequeña (SBWC) en el tratamiento de las hemorragias hipertensivas de los ganglios basales. Pacientes y métodos. Análisis retrospectivo de los datos clínicos de 174 pacientes con hemorragia hipertensiva de los ganglios basales tratados en nuestro hospital desde enero de 2018 hasta septiembre de 2020. Los pacientes se dividieron en dos grupos: uno sometido a neurocirugía endoscópica mínimamente invasiva (n = 90) y otro a microcirugía con SBWC (n = 84). Se compararon la duración de la operación, la tasa de eliminación del hematoma, la recidiva hemorrágica y el pronóstico. Resultados. En el grupo sometido a la endoscopia mínimamente invasiva, tanto la duración de la intervención como el tiempo de hemostasia fueron significativamente más breves, y la pérdida de sangre durante la intervención fue significativamente menor que en el grupo de microcirugía con SBWC (p menor de 0,001). La puntuación preoperatoria de la escala de coma de Glasgow (GCS) era de 8,64 ± 1,04 puntos en el grupo de la endoscopia y de 8,68 ± 1,02 puntos en el de la microcirugía (p > 0,05). A las 24 horas de la intervención, la puntuación de la GCS en los sometidos a la neuroendoscopia aumentó hasta 12,89 ± 1,56, con una diferencia significativa respecto al grupo de la microcirugía, que presentaba 11,18 ± 1,14 puntos (p menor de 0,001). El volumen del edema cerebral fue de 11,82 ± 3,25 mL en el grupo de la neuroendoscopia mínimamente invasiva y de 18,89 ± 3,15 mL en el de la microcirugía (p menor de 0,001). En comparación con el grupo sometido a esta última, en el grupo de la endoscopia, la eliminación del hematoma fue más extensa y el pronóstico resultó más favorable. Conclusiones. La neurocirugía endoscópica mínimamente invasiva se mostró más eficaz que la microcirugía con SBWC en el tratamiento de las hemorragias hipertensivas de los ganglios basales.

Clinical Study on a Modified Hematoma Puncture Drainage Treatment in Patients with Hypertensive Basal Ganglia Hemorrhage.

OBJECTIVE: We aim to investigate the clinical efficacy and safety of a modified hematoma puncture drainage treatment through the burr hole lateral to Kocher's point from the frontal lobe in patients with hypertensive basal ganglia hemorrhage. METHODS: Twenty-six patients were enrolled in the retrospective study. The volume of hematoma in those patients was between 25 and 35 mL, and the Glasgow Coma Scale scores were between 9 and 11; they were divided into a hematoma puncture drainage treatment group and a traditional conservative treatment group. The volume of remaining hematoma, neurological function defect scores, and life quality after treatment, duration of hospitalization, and cost of hospitalization were analyzed in these 2 groups. RESULTS: The volume of remaining hematoma was significantly less in the drainage group than that in the traditional group on the first day and the third day after treatment (P < 0.05). Posttreatment neurological function defect scores in the drainage group were statistically lower than those in the traditional group (P < 0.05). The duration of hospitalization was significantly shorter and the cost of hospitalization was also significantly less in the drainage group than that in the traditional group (P < 0.05). The Extended Glasgow Outcome Scale and Barthel Index scores were significantly higher in the drainage group than those in the traditional group (P < 0.05). There were no significant differences between the 2 groups in the complication rates (P > 0.05). CONCLUSIONS: The modified hematoma puncture drainage treatment represents an effective and safe way to treat hypertensive basal ganglia hemorrhage.

Isolated bilateral, large, basal ganglia haemorrhage following a traumatic brain injury: A case report.

Traumatic basal ganglia haemorrhage is rarely seen in clinical practice. Bilateral basal ganglia hematoma without any other cerebral lesions due to trauma is extremely uncommon and has been reported only in a few cases. Although the mechanisms of this condition are unclear, haemorrhagic contusions are thought to arise as a consequence of a shearing strain on cranial blood vessels due to high-velocity forces at the time of the injury. Here we describe a 63-year-old female patient with an isolated bilateral, large, basal ganglia haemorrhage secondary to a road traffic accident. The patient was promptly diagnosed and conservatively treated and had fully recovered after two months.

Association between systemic inflammatory response syndrome and hematoma expansion in intracerebral hemorrhage.

BACKGROUND: Hematoma expansion (HE) is a relatively common complication after intracerebral hemorrhage. OBJECTIVES: To explore the association between systemic inflammatory response syndrome (SIRS) and HE in patients with intracerebral hemorrhage (ICH). MATERIAL AND METHODS: From June 2013 to October 2020, the sociodemographic data and clinical data of 780 ICH patients were collected. The logistic regression analysis with odd ratios (ORs) and 95% confidence intervals (95% CIs) was performed to analyze the risk factors for HE in patients with ICH. RESULTS: Hematoma expansion occurred in 151 (19.36%) patients with ICH. Significant differences were presented between SIRS and HE (OR = 2.549, 95% CI: [1.497; 4.342], p = 0.0006). After adjusting the covariates, a further analysis showed that the respiratory rate >20 beats/min (OR = 3.436, 95% CI: [1.981; 5.960], p < 0.0001), white blood cell (WBC) > 12×109/L or WBC ≤ 4×109/L (OR = 2.489, 95% CI: [1.494; 4.149], p = 0.0005) increased the risk for HE in ICH patients. Our study also found that the significant differences between HE and non-HE patients in proportion of patients with history of diabetes mellitus, basal ganglia hemorrhage, hypothalamus hemorrhage and fasting blood glucose (all p < 0.05) (OR = 2.076, 95% CI: [1.274; 3.381], p = 0.0034), basal ganglia hemorrhage (OR = 2.512, 95% CI: [1.496; 4.218], p = 0.0005), hypothalamus hemorrhage (OR = 2.121, 95% CI: [1.007; 4.466], p = 0.0479), high C-reactive protein (CRP) (OR = 1.013, 95% CI: [1.002; 1.024], p = 0.0184), and hyperglycemia (OR = 1.099, 95% CI: [1.026; 1.178], p = 0.0074) were associated with an increased risk of HE in ICH patients. CONCLUSIONS: The SIRS is closely associated with the risk of HE. Respiratory rate >20 beats/min and WBC count >12(109/L) or ≤4(109/L) increased the risk for HE in ICH patients. These findings can help to achieve the early prevention of HE and improve the prognosis of ICH patients.

Combined Decompressive Hemicraniectomy and Port-Based Minimally Invasive Parafascicular Surgery for the Treatment of Subcortical Intracerebral Hemorrhage: Case Series, Technical Note, and Review of Literature.

BACKGROUND: Intracerebral hemorrhage (ICH) is a neurosurgical emergency. Combined decompressive hemicraniectomy (DHC) and minimally invasive parafascicular surgery (MIPS) may provide a practical method of managing subcortical ICH. OBJECTIVE: 1) To present a case series of combined DHC-MIPS for the treatment of subcortical-based ICH; 2) to describe technical nuances of DHC-MIPS; and 3) to provide a literature overview of MIPS for ICH. METHODS: The following inclusion criteria were used: 1) Glasgow Coma Scale (GCS) score <3-4; 2) admission within 6 hours of onset; 3) increased intracranial pressure caused by hemorrhage; 4) patient unresponsive to medical management; 5) hemorrhage >30 cm3; 6) subcortical location; and 7) midline shift (mm). Before DHC, sulcal cannulation used the following coordinates: intersection of tragus-frontal bone and midpoint of midpupillary line and midline; coronal suture: 3-4 cm posterior to this point). RESULTS: Three patients were selected: a 62-year old woman, a 45-year old woman, and a 36-year-old man. GCS and ICH scores on admission were 7 and 3, 3 and 4, and 3 and 4, respectively. ICH was located in left basal ganglia in patients 1 and 3 and right basal ganglia in patient 2, all with intraventricular extension. ICH volume was 81.7, 68.2, and 42.3 cm3, respectively. The postoperative GCS score was 11, 10, and 6, respectively. There were no intraoperative complications or mortalities. Evacuation was within 15 minutes in all patients. The modified Rankin Scale score was 3, 4, and 5, respectively, with semi-independence in case 1. CONCLUSIONS: Combined DHC-MIPS, with the use of craniometric points, can provide a unique and simple surgical option for the management of subcortical ICH.

Utility of serum amyloid A as a potential prognostic biomarker of acute primary basal ganglia hemorrhage.

BACKGROUND: Intracerebral hemorrhage (ICH) can lead to inflammation. Serum amyloid A (SAA) is an acute phase protein, which might be implicated in acute brain injury. We ascertain relationship between serum SAA and inflammation, severity plus outcome after ICH. METHODS: In this prospective, observational study, serum SAA concentrations were quantified in 159 healthy volunteers and 159 acute primary basal ganglia hemorrhage patients admitted within 24 h after stroke symptom. Prognostic parameters included death and a poor outcome (modified Rankin Scale score > 2) at 90 days after stroke. RESULTS: Serum SAA concentrations were substantially higher in patients than in controls. Among patients, serum SAA concentrations were strongly correlated with serum C-reactive protein concentrations, hematoma volume and National Institutes of Health Stroke Scale scores. Serum SAA appeared to be an independent predictor for 90-day death, overall survival and poor outcome. Under receiver operating characteristic curve, this protein exhibited similar prognostic capability, as compared to hematoma volume and National Institutes of Health Stroke Scale scores. CONCLUSIONS: Rising serum SAA concentrations, in close correlation with inflammation and hemorrhagic severity, are independently related to mortality and poor outcome after ICH, indicating that serum SAA might serve as a potential prognostic biomarker for ICH.

The correlation between the evolution of bilateral basal ganglia hemorrhage using MR imaging and neurological damage recovery in an infant with methylmalonic aciduria.

PURPOSE: We report on one patient with methylmalonic acidemia (MMA) who presented with symmetrical hemorrhage of the caudate nucleus accompanied by severe ventricular dilatation, follow-up magnetic resonance imaging (MRI) findings from one year later, and the clinical manifestations, neuropsychological scores, genetic test results, urine and blood laboratory results and evolution of the disorder. MATERIALS AND METHODS: This study describes the recent and remote neuropathologic findings, reviews the literature, and discusses the possible pathogenetic mechanisms of these central nervous system lesions. RESULTS: Patients with MMA may have signs of basal ganglia hemorrhage during acute onset, and the hemorrhage may disappear after treatment. During the treatment, both laboratory examination indexes and neuropsychological scores improved. There was a correlation between the evolution of bilateral basal ganglia hemorrhage using MRI(magnetic resonance imaging) and neurological damage recovery in this infant with MMA. CONCLUSION: There was a correlation between the evolution of the bilateral basal ganglia hemorrhage using MR imaging and neurological damage recovery in an infant with MMA. We recommend performing conventional MR and diffusion-weighted imaging (DWI) examinations in patients with MMA who present with neurological symptoms.

Variant Type of Posterior Reversible Encephalopathy Syndrome Associated with Deep Brain Hemorrhage: Case Report and Review of the Literature.

BACKGROUND: Various radiologic patterns of posterior reversible encephalopathy syndrome (PRES) have been reported. Among them, PRES involving brainstem, thalamus, or deep white matter and lacking parieto-occipital edema is rare. Although PRES in general has a benign course, PRES-related intracranial hemorrhage has been associated with a poor prognosis. We report a case of variant type of PRES associated with deep brain hemorrhage and discuss the characteristics of PRES-related intracranial hemorrhage via a literature review. CASE DESCRIPTION: A woman aged 41 years with a history of untreated hypertension presented to our hospital complaining of severe headache and with an elevated blood pressure of 237/142 mmHg. Computed tomography revealed a hemorrhage in the left thalamus and basal ganglia. Magnetic resonance imaging revealed remarkable hyperintensity in the left cerebellum, pons, bilateral temporal lobes, bilateral basal ganglia, and bilateral cerebral white matter on fluid-attenuated inversion recovery imaging, which represented vasogenic edema. The parieto-occipital regions were unremarkable. Given this clinical presentation, PRES associated with deep brain hemorrhage was suspected. The patient received strict blood pressure control treatment, which resulted in gradual symptom improvement. Magnetic resonance images obtained 1 month after admission demonstrated an almost complete resolution of the edema. CONCLUSIONS: Although hemorrhage in the thalamus, basal ganglia, or brainstem is uncommon in patients with PRES, it may occur in patients with variant type of PRES involving these lesions. It is important to recognize the presence of variant patterns of clinical features and radiologic findings of PRES to allow for early identification and appropriate treatment.

Computerized Tomography Radiomics Features Analysis for Evaluation of Perihematomal Edema in Basal Ganglia Hemorrhage.

To evaluate the edema area around basal ganglia hemorrhage by the application of computerized tomography (CT)-based radiomics as a prognostic factor and improve the diagnosis efficacy, a total of 120 patients with basal ganglia hemorrhage were analyzed retrospectively. The texture analysis software Mazda 3.3 was used to preprocess the CT images and manually sketch the region of interest to extract the texture features. The extracted texture features were selected by Fisher coefficient, POE+ACC and mutual information. The texture discriminant analysis uses the B11 module in the Mazda 3.3 software. The data were randomly divided into a training dataset (67%) and test dataset (33%). To further study the texture features, the training dataset can be divided into groups according to the median of GCS score, NIHSS score, and maximum diameter of hematoma. Random forest model, support vector machine model, and neural network model were built. AUC of the receiver operating characteristics curve was used to assess the performance of models with test dataset. Among all texture post-processing methods, the lowest error rate was 2.22% for the POE+ACC/nonlinear discriminant. For the maximum diameter of hematoma, GCS score, and NIHSS score group, the lowest error rate were 26.66%, 23.33%, and 30.00%, respectively. The values of AUCs were 0.87, 0.81, and 0.76, for random forest model, support vector machine model, and neural network model in the test dataset, respectively. Radiomic method with proper model may have a potential role in predicting the edema area around basal ganglia hemorrhage. It can be used as a secondary group in the diagnosis of edema area around basal ganglia hemorrhage.

Improvement of Writer's Cramp from an Old Lesion in the Contralateral Hemisphere with Transient Gait Disturbance After Thalamotomy.

BACKGROUND: Stereotactic ventro-oral thalamotomy has been performed in cases of focal task-specific dystonia, including writer's cramp, with excellent outcomes. However, no reports have revealed the outcome of ventro-oral thalamotomy in a patient with a contralateral cerebral lesion. We describe a patient with left-hand writer's cramp with an old lesion in the left hemisphere and transient gait disturbance after right ventro-oral thalamotomy. CASE DESCRIPTION: A 43-year-old man had a hemorrhage in the left basal ganglia due to cerebral arteriovenous malformation at 22 years of age, and right hemiparesis remained as a sequela. He developed left-handed writing ability; however, he became aware of the stiffness of his left hand and difficulty in writing. Writer's cramp was diagnosed. Medical treatments were not effective, and right ventro-oral thalamotomy was performed. Although his writing ability improved, he could not walk. After performing rehabilitation, his walking completely improved, reaching the level before surgery, after 3 months, and his writer's cramp was completely cured. CONCLUSIONS: In patients with basal nucleus lesions, gait disturbance may appear transiently after contralateral thalamotomy. It is crucial to fully explain the potential complications, particularly in relation to temporal gait disturbances, and obtain informed consent.

Guillain-Barré syndrome as a complication of hypertensive basal ganglia haemorrhage.

We aimed to study the potential relationship of Guillain-Barré syndrome (GBS) and intracranial haemorrhage (ICH). We present a case of a 70-year-old hypertensive woman who developed global weakness, eventually becoming quadriplegic, during an inpatient stay for treatment of a basal ganglia haemorrhagic stroke. Guillain-Barré syndrome was confirmed and treatment initiated. She responded well to intravenous immunoglobulin treatment and then subsequently continued with rehabilitation. There have been a few case reports of GBS as a complication of spontaneous intracranial haemorrhage (ICH) or traumatic brain injury. It may not be a coincidence that our patient developed GBS shortly after presentation. There may be an immunological explanation with immune activation following neuronal injury after ICH with associated blood-brain barrier breakdown. GBS following ICH adds further complexity to treating patients who are already critically ill. If patients develop new weakness after ICH, there should be a high index of suspicion for GBS. It should be distinguished from critical illness neuropathy/myopathy and other causes of weakness in critical care patients because the treatment is very different. Immune activation and sensitization to myelin-associated proteins may be the underlying pathophysiological basis.

Treatment of Central Paralysis of Upper Extremity Using Contralateral C7 Nerve Transfer via Posterior Spinal Route.

BACKGROUND: Contralateral C7 nerve transfer is widely applied for the treatment of brachial plexus injuries or central paralysis of the upper extremities. The surgical approach has evolved from the precervical subcutaneous route to the prespinal route, which is currently the most commonly used one. We report a patient with central paralysis of the right upper extremity treated with contralateral C7 nerve transfer via the posterior spinal route. CASE DESCRIPTION: A 59-year-old female patient was admitted on 3 July, 2018 with right hemiplegia. The muscle strength of the right lower and upper extremities was grade 4 and 0, respectively. On the basis of magnetic resonance imaging, she was diagnosed with central paralysis of the right upper extremity. Considering the short length of the patient's healthy C7 nerve, contralateral C7 nerve transfer via the posterior spinal route was performed. No intraoperative complication was encountered. The patient reported slight numbness of the volar side of the left thumb, middle finger, and index finger after surgery. The patient showed a right shrug movement 1.5 months after surgery. CONCLUSION: We propose carrying out contralateral C7 nerve transfer via the posterior spinal route because of the shorter distance, no need for nerve transplantation, and low occurrence of the complications encountered with the prespinal route (such as vertebral artery injuries, esophageal fistula, and upper extremity pain when swallowing).

Supernumerary phantom limb in a patient with basal ganglia hemorrhage - a case report and review of the literature.

BACKGROUND: Supernumerary phantom limb (SPL) is a rare neurologic phenomenon, in which a patient misperceives an extra limb in addition to the original set of limbs. We report a case of SPL in a patient with a right basal ganglia hemorrhage and review the previous literature about this peculiar phenomenon. CASE PRESENTATION: Two days after the event of a right basal ganglia hemorrhage, a 78-year-old male reported a phantom arm protruding from his left shoulder. He could not see or touch the phantom arm but he felt the presence of an addition arm lateral to his paretic arm. Pain or sensory discomfort were absent in either the paretic arm or the phantom arm. He stated that he could intentionally move the phantom arm independent of his paretic arm. The examination showed that the passive movement of his paretic arm did not elicit any movement of his phantom arm. We diagnosed the SPL as a complication of the hypertensive basal ganglia hemorrhage and treated him with anti-hypertensive medications. His phantom arm persisted for 3 weeks, and it gradually faded away. CONCLUSION: SPL had been reported as a rare complication of various types of cerebral lesions. Right hemispheric lesions were most frequently associated with the SPL. Considering the intentional movement of the phantom arm, we deduced that the SPL might result from the impairment of the sensory feedback system for both internal body image and motor movement.

Natural History of Intracranial Absorbable Gelatin Powder.

This case report documents the natural history of intracranial absorbable gelatin powder. We depict the serial imaging of Surgifoam in the cavity of an intracranial hemorrhage cavity after surgical evacuation.
