Secondary Trigeminal Neuralgia Caused by Cerebellopontine Angle Arachnoid Cyst in A 27-Year-Old Female: A Case Report

PURPOSE

Secondary (TN) caused by an arachnoid cyst in the (CPA) region is a rare finding. Based on the reported literature, there are only 5 cases of secondary trigeminal neuralgia caused by an arachnoid cyst in the cerebellopontine angle region.

CASE REPORT

A 27-year-old female presented to our neurosurgery clinic with a 2-year history of brief episodes of paroxysm pain in the left cheek. The pain was described as an electric shock-like pain triggered by simple stimuli. The magnetic resonance imaging (MRI) showed a well-confined cystic lesion in the left CPA, which compresses the left pons and the cisternal segment of the left trigeminal nerve. The patient was managed operatively to fenestrate the cyst and decompress the trigeminal nerve. The histopathological result of the cyst wall was consistent with an arachnoid cyst. Six months after surgery, the patient is in good health condition and symptom-free without medication.

CONCLUSION

Arachnoid cyst in the CPA region is one of the rare causes of secondary TN. Preoperative imaging with MRI is important to provide better results to differentiate the pathology. Surgical treatment to fenestrate the arachnoid cyst and decompress the trigeminal nerve have a good result and can improve the patient's quality of life.

Comparison between Dura-Splitting Technique with Duraplasty in Symptomatic Patients with Chiari Malformation Type I: A Systematic Review and Meta-analysis

BACKGROUND: There are many surgical procedures for CIM patients, posterior fossa decompression with fibrous band excision, with additional duraplasty, or syringosubdural shunt for syringomyelia related CIM. Prospective studies have been carried out but yet no conclusion, on which one is the best option. The objective of this study was to assess qualitatively the outcome of posterior fossa decompression with dura-splitting (PFDDS) technique compared to posterior fossa decompression with duraplasty (PFDDP) for treating CIM patients. AIM: This study aimed to give us a preference while conducting surgery in a patient with Chiari malformation type I (CIM) between posterior fossa decompression with incision of the fibrous band of the dura (dura-splitting/DS) technique and duraplasty (DP) technique. METHODS: The analysis conducted using PRISMA flowchart with PICO framework (Patient: Chiari malformation type I patient over preschool age; Intervention: Dura-splitting; Comparison: Duraplasty; and Outcome: Complication rate, length of stay, reoperation rate, syrinx reduction, symptomatic improvement, and operation time) and already registered for meta-analysis study with database searching from PubMed, the Cochrane Library, and Google Scholar that following inclusion criteria: (1) Original study; (2) study that compares DS and DP in CM- I; and (3) patient age over preschool age. RESULTS: A review of five included studies involving 458 patients met the inclusion criteria, in which 319 patients treated with DS surgery and 139 for DP surgery for this study. Significantly DS technique correlated lower rate of complication (RR = 0.20; p < 0.0001), shorter length of stay (MD = −3.53; p = 0.0002), and shorter operation time (MD = −58.59; p = 0.0004). No significant differences in reoperation rate (RR = 1.90; p = 0.22), symptom improvement (RR = 1.12; p = 0.44), and syrinx reduction (RR = 1.11; p = 0.56) were noted. CONCLUSIONS: Posterior fossa decompression using the DS technique is associated with a lower rate of complication, shorter length of stay, and shorter operation time. However, no significant differences were found in the reoperation rate, symptom improvement, and syringomyelia reduction between these two techniques.

Role of Procalcitonin and C-reactive Protein as Marker of Sepsis in Major Burn Patients: A Systematic Review and Meta-analysis

AIM: Although absolute values for C-reactive protein (CRP) and procalcitonin (PCT) are well known to predict sepsis, it remains unclear how their diagnostic value in major burn patients as metabolic changes in burn patient mimic signs and symptoms for sepsis. This paper attempts to clarify these points for both of the markers. METHODS: A comprehensive literature search of PubMed, Scopus, DOAJ, Web of Science, and the Cochrane Library databases for studies published up to June 1, 2020, that evaluated PCT and/or CRP as a marker for diagnosing sepsis in burn patients was conducted. Review Manager 5.3 was used to analyze the data. RESULTS: A total of 11 literatures were obtained. The combined sensitivity and specificity for PCT as assessed by meta-analysis were 88% and 89%, respectively. The combined sensitivity and specificity of CRP were described as 85.5% and 57.5%, respectively. Meta-analysis cannot be performed for CRP parameters because there are only two literatures that include CRP diagnostic test values. DISCUSSION: PCT and CRP have additional diagnostic value for sepsis in patients with major burns. The pooled sensitivity and specificity of PCT are excellent. Although the difference in sensitivity between PCT and CRP is not very large, there are distinct differences in specificity. A low CRP specificity value will show many “false positives” when CRP is used as a biomarker. CONCLUSION: PCT provides a better diagnostic value than CRP in cases of sepsis in major burn patients. More study on combination of biomarker, clinical presentation, and microbial culture for diagnosing sepsis are needed. Further large-scale research with cohort or case control design should be done.

Neurocysticercosis presented as a solitary cystic parenchymal lesion mimicking primary brain tumor: A case report

•

Neurocysticercosis (NCC) is an endemic zoonotic infection in pork-eating region, including Bali.

•

Despite its high prevalence, diagnosing an NCC can be challenging due to the protean clinical manifestations.

•

Herein we describe an NCC case mistakenly diagnosed as a brain tumor, only later that we discovered the active larvae of Taenia solium, the pathogen which causes NCC.

•

A high index of suspicion towards NCC should always be maintained, particularly among patients originated from endemic area.

•

Appropriate treatment with anthelminthic may result in full disease resolution, thus precluding unnecessary invasive approach.

Introduction

Neurocysticercosis (NCC) is an infection of the central nervous system by the larval stage of pork tapeworm (Taenia solium/T. solium). Diagnosing NCC can be challenging, particularly among those who reside in areas with rare occurrence of NCC and atypical manifestation such as a solitary parenchymal lesion. We treated a patient whose initially was diagnosed with brain abcess and later, brain tumor, only finally revealed to be an NCC case.

Case report

A 25-year old male suffered from multiple focal-to-bilateral tonic clonic seizures, was initially diagnosed as brain abscess. He was given antibiotics and anti-seizure medication but the seizure relapsed with a typical semiology. Physical examination demonstrated grade I papilledema, grade 4+ hemiparesis, and headache of vascular origin. Patient was suspected to have oligodendroglioma after underwent head MRI examination and subsequent tumor resection was performed. Pathological anatomy evaluation demonstrated multiple cystic segments containing larva of tapeworm, supporting a diagnosis of active NCC infection. After 14-day course of antheminthic treatment and resumed AED, patient was seizure-free and NCC was not found upon follow-up CT scan.

Conclusion

NCC, with respect to clinical and radiological manifestations, can be protean. A high index of suspicion towards NCC should always be maintained, particularly among patients originated from endemic area. Appropriate treatment with anthelminthic may result in full disease resolution, thus precluding unnecessary invasive approach.

Air gun wound: bihemispheric penetrating brain injury in a paediatric patient

Air guns are classified as low-velocity missiles and they usually considered safe and harmless. Despite that fact, air guns still can make serious or life-threatening injuries. Most of air gun injuries occur in paediatric population. A 2-year-old boy was shot in the forehead withan air gun accidentally. Skull radiography and non-contrast CT scan of the head were performed and showed penetrating bihemispheric brain injury from the left frontal to right occipital lobes at the level of the lateral ventricle with a metal-density foreign body at the right occipital. A projectile was successfully extracted via craniotomy, without complications. Air guns have the potential to cause fatal, life-threatening injury especially in children. Imaging is crucial for the evaluation of wound ballistics. Understanding about the mechanism of projectiles and wound ballistics is very helpful for radiologists to conceptualize these injuries when interpreting these cases. The role of radiology in ballistic wound cases is critical and important, both for clinical and forensic settings.

Central Nervous System Tuberculoma Complicated with Spinal Arachnoiditis in Immunocompetent Patient

BACKGROUND:

Central nervous system (CNS) tuberculosis (TB) can manifest as meningitis, abscess, tuberculoma or other manifestations. CNS TB is a rare TB complication, and its diagnosis remains a challenge since it has clinical and imaging features that resemble other diseases. The antituberculosis treatment has a significant role in determining a patient’s outcome and prevent complications and mortality.

CASE PRESENTATION:

Here, we report a case of CNS TB manifested as tuberculoma in immunocompetent patient complicated with spinal arachnoiditis. Despite a treatment delay, the patient still showed clinical improvement after proper treatment with a combination of antituberculosis drug and corticosteroid.

CONCLUSION:

Central Nervous System Tuberculoma Complicated with Spinal Arachnoiditis in Immunocompetent Patient CNS tuberculoma is a rare CNS TB manifestation, and its diagnosis remain a challenge since its clinical symptoms and radiological findings could mimic other cases such as malignancy, pyogenic abscess, toxoplasmosis, sarcoidosis, or neurocysticercosis.
