A CORRELATION OF NEUROCYSTICERCOSIS AND IGG4 ANTIBODIES

TOPIC: Critical Care TYPE: Fellow Case Reports INTRODUCTION: In endemic regions, 30% of patients presenting with epilepsy, have evidence neurocysticercosis. the US, between years 2003 and 2012, there were more than 18,000 hospitalizations for A study done in 2002 showed that IgG4 was found sera cerebral cysticercosis 97.8% time. Reliance on immunological assays holds importance due to lower costs comparison imaging studies impoverished areas. This case presentation follows a patient ring-enhancing brain lesion, positive antibodies, cells tissue biopsy. CASE PRESENTATION: 56-year-old male past medical history hypertension, recent head injury no other risk factors, presented evaluation syncope. Before syncopal episode, seen by primary physician sustained his complaints recurrent fevers, headache, blurred vision. The prescribed steroids antibiotics but did not feel any improvement ended having episode brief loss consciousness. Magnetic resonance contrast 17mm right mid corona radiata/mid-lateral ventricle peripherally enhancing mass surrounding white matter edema centralized restricted diffusion. Patient admitted intensive care unit treated antibiotics, steroids, antiepileptics. Stereotactic biopsy parenchyma mildly increased cellularity consisting primarily glial suggestive reactive tissue. All labs negative except Cysticercosis IgG Antibody. Computed tomography abdomen pelvis 3 cm low-density lesion lobe liver which rare CMV inclusions infected background storiform fibrosis lymphoplasmacytic inflammation numerous cells. started albendazole over course few days, symptoms significantly improved. DISCUSSION: Brain only tissue, hence ensure is present, further tests ordered led revelation pathognomonic IGG4 related disease, however, lack necessary diagnostic criteria (serum above 135 histopathology showing greater 40%), conclusion reached. However, antibody, neurocysticercosis higher differential as most commonly antibody serum or CSF. CONCLUSIONS: Our findings correlation IgG4, strengthen promise better immunodiagnostic tool thereby fighting issues accessibility cost-effectiveness REFERENCE #1: O'Neal SE, Flecker RH.
