BACKGROUND Atlantoaxial sublaminar wiring has many known complications related to hardware failure, but intracranial hemorrhage is a rare complication. OBSERVATIONS A 61-year-old female patient with prior atlantoaxial sublaminar wiring for odontoid fracture nonunion experienced decreased level of consciousness due to a subarachnoid and subdural hemorrhage of the posterior fossa with intraventricular extension and hydrocephalus. Rupture of the sublaminar wire with intramedullary protrusion was the cause of the hemorrhage. The patient was treated with ventriculostomy for hydrocephalus and occipital cervical fusion for spinal instability, along with removal of the broken wire and drainage of a hematoma. LESSONS This uncommon cause of intracranial hemorrhage highlights an additional risk of atlantoaxial sublaminar wiring compared with other atlantoaxial fusion techniques. In addition, this case suggests cervical instrumentation failure as a differential diagnosis of subarachnoid and subdural hemorrhage of the posterior fossa when a history of prior instrumentation is known.

Abstract Objectives There are 3 types of intracranial hemorrhage (ICH): 1) subarachnoid hemorrhage (SAH), CIE10:I60; 2) intraparenchymal hemorrhage (IPH), I61 and 3) subdural hemorrhage (SDH) I62. Epidemiological data on this field are scarce in Mediterranean countries. Our goal was to determine whether the relationship of ICH mortality with gender and age was different for the 3 types of HIC. Methods Data were retrospectively obtained from the Spanish National Institute of Statistics. Deaths/100.000 population of SAH, IPH and SDH were assessed for the entire Spanish population since 2008 to 2017 (n=46,527,039). Year 2017 was the last available for analysis. Incidence was analyzed for men and women and for age strata (<1 years of age, 2–10, 11–20, 21–30, 31–40, 41–50, 51–60, 61–70, 71–80; >80). Results In order to fit in the abstract space, only data of 2017 are presented, although years 2008 to 2017 were also analyzed and results were similar. Mortality/100,000 of IPH stayed very low under 40 years of age and then grew exponentially in both, men and women, and was significantly higher for men for all age strata. Mortality of SDH was much lower but behaved in a similar way: exponential growth since 40s and lower incidence in women. SAH behaved differently: it started to be significant since 20 years of age and there were no gender differences. Conclusion Mortality of intraparenchymal and subdural hemorrhage increases exponentially since 40 years of age and is lower in women. On the contrary, mortality of subarachnoid hemorrhage increases earlier and there are no gender differences.

Objective: To verify the ability of the deep learning model in identifying five subtypes and normal images in noncontrast enhancement CT of intracranial hemorrhage. Method: A total of 351 patients (39 patients in the normal group, 312 patients in the intracranial hemorrhage group) performed with intracranial hemorrhage noncontrast enhanced CT were selected, with 2768 images in total (514 images for the normal group, 398 images for the epidural hemorrhage group, 501 images for the subdural hemorrhage group, 497 images for the intraventricular hemorrhage group, 415 images for the cerebral parenchymal hemorrhage group, and 443 images for the subarachnoid hemorrhage group). Based on the diagnostic reports of two radiologists with more than 10 years of experience, the ResNet-18 and DenseNet-121 deep learning models were selected. Transfer learning was used. 80% of the data was used for training models, 10% was used for validating model performance against overfitting, and the last 10% was used for the final evaluation of the model. Assessment indicators included accuracy, sensitivity, specificity, and AUC values. Results: The overall accuracy of ResNet-18 and DenseNet-121 models were 89.64% and 82.5%, respectively. The sensitivity and specificity of identifying five subtypes and normal images were above 0.80. The sensitivity of DenseNet-121 model to recognize intraventricular hemorrhage and cerebral parenchymal hemorrhage was lower than 0.80, 0.73, and 0.76 respectively. The AUC values of the two deep learning models were above 0.9. Conclusion: The deep learning model can accurately identify the five subtypes of intracranial hemorrhage and normal images, and it can be used as a new tool for clinical diagnosis in the future.

AbstractPosterior fossa tumors are commonly encountered in pediatric age group patients. Most of these tumors present with features of hydrocephalus in the child. Conventionally, these cases are managed by suboccipital craniotomy with decompression of the tumor mass to establish the free flow of cerebrospinal fluid (CSF) across fourth ventricle and aqueduct of Sylvius. Following resection of posterior fossa tumor, appearance of subdural hygroma is a rare phenomenon.Though few cases of subdural hygroma are reported in literature following foramen magnum decompression in Chiari's malformation, their appearance following posterior fossa tumor resection is alien to medical literature and limited to only two case reports. Here the authors present a patient with periencephalic subdural panhygroma (PSP) following posterior fossa tumor resection who was successfully treated with a ventriculoperitoneal shunt (VPS) to accomplish a symptomatic and radiologic remission.

Intrauterine transfusion is the most common and successful intrauterine procedure for the treatment of fetal anemia due to red cell alloimmunization. Fetal intracranial hemorrhage is a very rare complication of intrauterine transfusion in patients with Rh(D) alloimmunization and it has been demonstrated only in a few case reports in the literature. Herein, we described a case of grade IV intraventricular hemorrhage that was diagnosed following the first intrauterine transfusion and reviewed the literature about the fetal intracranial hemorrhage that occurred after intrauterine intravascular transfusion procedure.

ABSTRACT:Objective:To determine physical and cognitive outcomes of full-term infants who suffered intracranial hemorrhage (ICH) at birth.Methods:A retrospective hospital-based, follow-up study of infants treated in London, Ontario between 1985 and 1996. Follow-up was conducted by telephone interviews and clinic visits. Outcome was measured according to physical and cognitive scales. Perinatal risk factors and hemorrhage characteristics were correlated with final outcome.Results:For this study 66 infants with ICH were identified, of which seven died during the first week of life. We obtained follow-up in all but ten cases (median = 3-years; range 1.0 to 10.9 years). Overall, 57% of infants had no physical or cognitive deficits at follow-up. Death occurred most frequently among those with primarily subarachnoid hemorrhage (19%) and the most favorable outcomes occurred among those with subdural hemorrhage (80% had no disability). In univariate models, thrombocytopenia (platelet count ≤ 70 x 109/L), increasing overall hemorrhage severity, frontal location and spontaneous vaginal delivery as opposed to forceps-assisted delivery increased risk for poor outcome. In multivariate models, all these factors tended towards increased risk, but only thrombocytopenia remained significant for physical disability (OR = 7.6; 95% CI = 1.02 – 56.6); thrombocytopenia was borderline significant in similar models for cognitive disability (OR = 4.6; 95% CI = 0.9 – 23.9).Conclusion:Although forceps-assisted delivery may contribute to ICH occurrence, our study found better outcomes among these infants than those who had ICH following a spontaneous vaginal delivery. Hemorrhage in the frontal lobe was the most disabling hemorrhage location and if multiple compartments were involved, disability was also more likely to occur. However, in this report we found that the factor that was most likely to contribute to poor outcome was thrombocytopenia and this remained important in multivariate analysis.

✓ A dural arteriovenous malformation (AVM) of the posterior fossa can produce persistent tinnitus, convulsions, and dementia. Successful therapeutic embolization may result in a complete cure, but in some cases, patients do not respond to the treatment. The authors report a patient with a dural AVM of the posterior fossa that did not respond to repeated intravascular treatments, but resulted in an arteriovenous shunt in the scalp around the ventriculoperitoneal shunt system. Although several hypotheses have been proposed on the pathogenesis of dural AVMs, the underlying mechanisms remain unknown. The rare complication we encountered may shed some light on the pathogenesis of dural AVMs.

Maternal Predictors

Neonatal thrombocytopenia is a rare complication of maternal autoimmune thrombocytopenia, and no maternal predictors of its gravity and potential complications have been identified. Neonatal cerebral hemorrhage, a feared event in the setting of autoimmune thrombocytopenia, is fortunately uncommon, but it can occur in utero or in the perinatal period, with potentially serious consequences. The authors report the case of a boy born to a mother affected by autoimmune thrombocytopenia, who presented with severe thrombocytopenia at birth and developed intracranial hemorrhage despite mild maternal thrombocytopenia at delivery and a prompt preventive treatment of the newborn. Platelet count should be tested at birth in all babies born from mothers with autoimmune thrombocytopenia, irrespective of maternal platelets counts during pregnancy or at delivery, and should be closely monitored during the first days of life. Systematic early and serial cranial ultrasound might be advocated in the setting of neonatal thrombocytopenia.
