Management of pseudomeningocele following posterior fossa tumor surgery with absence of hydrocephalus: A case report.

BACKGROUND: The management of pseudomeningocele can be challenging and treatment options vary in the literature. There is currently no algorithm or standard protocol regarding the type and timing of treatment. Until now, there has been a little literature and no case report that used puncture techniques as a conservative treatment. We reported the effectiveness of fluid puncture and pressure dressing as an aggressive nonsurgical management of pseudomeningocele. CASE PRESENTATION: A 5-year-old boy with posterior fossa tumor underwent midline suboccipital craniotomy tumor removal and decompression. A week after the surgery, the patient developed buldging in the operation region. Head CT scan showed pseudomeningocele in suboccipital region, a residual calcified tumor was seen, and no enlargement of ventricle. Conservative management was taken and the patient was managed with fluid puncture and pressure dressing. The reduction in size of the pseudomeningocele appeared within 14 days. CONCLUSION: Pseudomeningocele is a common complication of posterior fossa surgery. Nonsurgical treatment is the management of choice to reduce the symptoms. Fluid puncture and pressure dressing are effective in reducing symptoms. Surgical intervention is recommended when conservative treatment fails.

A Case Report of Pediatric Germinoma With SARS-CoV-2: Lessons Learned From an Academic Tertiary Referral Hospital in Asian COVID Epicentrum.

BACKGROUND: Patients often present with one or more pre-existing underlying chronic diseases that will affect their prognoses and mortality. A study revealed that the majority of children with SARS-CoV-2 infection presented with either no or a single symptom. Meanwhile, multiple other studies reported of more severe diseases in SARS-CoV-2 infected children with brain tumor and/or cancer as a whole. CASE REPORT: The patient was a 15-year-old male who was referred to our hospital with complaints of vomiting, headache, and signs of worsening right hemiparesis. Initial MRI suggested of a high-grade astrocytoma and hydrocephalus, but a subtotal tumor resection and external ventricular drainage gave light to a histopathological examination conclusive of germinoma. After adhering to radiotherapy and recovering well, the patient fell into unconsciousness 9 months later and tested positive for SARS-CoV-2 infection. The patient deteriorated on the third day of admission with respiratory failure, shock, arrythmias, fever, and increased d-dimer. After multiple attempts stabilization with ventilatory, defibrillator, and medical support, the patient deceased at the 6th day of admission. DISCUSSION: Cancer patients with COVID-19 have been reported to have relatively higher mortality rate when compared to the non-infected patients. Moreover, malignancies were also reported to increase the risk of developing more severe disease in children. Although rare, patients may develop a condition called multisystem inflammatory syndrome in children (MIS-C), which is a state of hyperinflammatory and severe illness temporally associated with COVID-19 infection. No observations have been evident in indicating the influence of COVID-19 on the neurological state of the patient, but we believe that it may be reasonable to not yet exclude the possibility of it of exacerbating the CNS malignancy our patient suffered from. CONCLUSION: Children with intracranial brain tumor infected by SARS-CoV-2 may fall into a worse condition with poor prognosis, exacerbated by severe acute respiratory distress and the need for breathing support in intensive care unit. Multidisciplinary tumor boards have to convene regularly, including through call-conferences and telemedicine platforms.

The recurrent plexiform neurofibroma of the scalp in neurofibromatosis type 1: illustrative case.

BACKGROUND: Plexiform neurofibroma is a benign tumor of the peripheral nerves. It is an unusual variant of neurofibroma originating from all parts of the nerve. Plexiform neurofibroma is primarily pathognomonic and exhibits an unusual variant from neurofibromatosis type 1 (NF1). The possibility of malignancy and recurrence are the main reasons for long-term, close follow-up. OBSERVATIONS: The authors report a case of a 14-year-old girl with a recurrent plexiform neurofibroma derived from the peripheral nerves, which also presented with a typical sign of NF1 disease. The aim of the tumor resection is symptomatic relief. LESSONS: Accomplishing a good outcome can be related to good perioperative planning and a precise operative procedure. The result of anatomical pathology determines the prognosis of the patient. Clinical examination and radiological studies are needed to evaluate the recurrence of complications after surgical procedures.

Clinical Outcomes of MLC601 (NeuroAiDTM) in Traumatic Brain Injury: A Pilot Study.

BACKGROUND: MLC601 is a natural product formulation from Chinese medicine that is extensively studied in ischemic stroke. Traumatic brain injury (TBI) shares pathophysiological mechanisms with ischemic stroke, yet there are few studies on the use of MLC601 in treating TBI. This Indonesian pilot study aimed to investigate clinical outcomes of MLC601 for TBI. METHODS: This randomized controlled trial included subjects with nonsurgical moderate TBI allocated into two groups: with and without MLC601 over three months in addition to standard TBI treatment. Clinical outcomes were measured by the Glasgow Outcome Scale (GOS) and Barthel Index (BI) observed upon discharge and at months (M) 3 and 6. RESULTS: Thirty-two subjects were included. The MLC601 group (n = 16) had higher GOS than the control group (n = 16) at all observation timepoints, though these differences were not statistically significant (p = 0.151). The BI values indicated a significant improvement for the MLC601 group compared to the control group at M3 (47.5 vs. 35.0; p = 0.014) and at M6 (67.5 vs. 57.5; p = 0.055). No adverse effects were associated with MLC601 treatment. CONCLUSION: In this cohort of nonsurgical moderate TBI subjects, MLC601 showed potential for a positive effect on clinical outcome with no adverse effects.

Bilateral skull fracture with massive epidural hematoma secondary to pin-type head fixation in a pediatric patient: Case report and review of the literature.

INTRODUCTION: A head fixation device containing pins is common equipment used in neurosurgical procedures. Previous reports analysed some of the complications associated with the application of this device for adults and children, even the indications for the use in pediatric are not well defined. CASE PRESENTATION: An 11-year-old girl diagnosed with non-communicating hydrocephalus, caused by posterior fossa tumor. During the surgery, complications were found in the form of acute epidural hematoma due to head fixation pins. So, the operation was stopped. Emergent CT scan was carried out and showed a bilateral skull fracture and a massive right-sided epidural hematoma. An emergency craniotomy for clot removal was performed and five days later, a second surgery was carried out uneventfully for the residual tumor. The patient fully recovered after the second surgery. DISCUSSION: Complications due to the use of a pin head fixation are easier to occur in pediatric patients, because the bones are thinner and need more carefull strategy when pinning. With promp identification of any complications and earlier treatment, the good outcome will be achieved. We compared our case report with published literature in order to suggest the way to prevent this complication. CONCLUSION: Skull fractures and associated epidural hematomas in pediatric patients need to be considered as possible complications of the pin-type head fixation application. The head fixation devices in pediatric need to be used with great caution and knowing the risk factors, safe technique for application and management of complications will prevent worse outcome.

Duraplasty using amniotic membrane versus temporal muscle fascia: A clinical comparative study.

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr. Soetomo General Hospital, Surabaya. The amniotic membrane allograft, was sutured to cover the dural defect for eight randomly chosen patients (Group I). The fascial autograft from the temporal muscle had been applied for eight other patients (Group II). Between 10 and 20 weeks after surgery, the patients underwent cranioplasty and dural healing evaluation by cerebrospinal fluid (CSF) leakage testing through the edge of the dural defect. The fibrocyte infiltration around the edge of the dural defect was examined histologically. Statistical analysis, using an independent t-test, was performed with a confidence interval of 95%. The results of the clinical and histological analysis suggest that an amniotic membrane graft was able to provide watertight dural closure and adequate fibrocyte infiltration comparable with that provided by temporalis muscle fascia. This study shows that using an amniotic membrane in neurosurgery has a potential advantage over an alternative dural healing.

Upward migration and peroral extrusion of a peritoneal shunt catheter: Case report and review of the literature.

BACKGROUND: Various complications after ventriculoperitoneal (VP) shunt surgery have been reported, but peroral extrusion of peritoneal catheter is an extremely rare complication, and only 20 cases have been reported since 1987. The pathophysiology still remains unclear and the management is challenging. CASE DESCRIPTION: A 5-year-old boy presented with a catheter coming out of his mouth. The boy had a posterior fossa tumor surgery and had VP shunt insertion 1 year earlier. Clinical signs and imaging studies showed that the distal end of the catheter had perforated the gaster and migrated upward and extruded through the mouth. Emergency removal of the shunt and proper treatment were done and he made uneventful recovery. CONCLUSION: Peroral extrusion of VP shunt is extremely rare. Clinicians should be aware of this complication. With early diagnosis and proper management, the prognosis for good recovery is excellent, with only two deaths being reported in the literature. Complication of shunt extrusion is difficult to avoid, but knowing the risk factors, pathophysiology and proper management will decrease the morbidity and mortality of such cases.
