Paralytic ileus as first symptom of Miller Fisher syndrome: A case report.

Introduction: Miller Fisher syndrome (MFS), regarded by many scholars as a variant of Guillain Barre syndrome (GBS), accounts for approximately 5% to 10% of GBS cases. The typical clinical manifestations of MFS are extraocular muscle paralysis, ataxia, and tendon reflex loss or disappearance. To date, intestinal obstruction has rarely been reported as the initial symptom.
Patient Concerns: A 48-year-old woman presenting with abdominal pain and distention was diagnosed with paralytic ileus. There was no significant improvement in symptoms after symptomatic treatment. After that, the patient developed visual rotation, with limited binocular abduction and adduction, and ataxia. Anti-ganglioside testing revealed positive anti-ganglioside antibodies.
Diagnosis: The patient was diagnosed as MFS.
Interventions: The early stage is mainly symptomatic treatment of paralytic ileus. After MFS was diagnosed, the patient was given large amounts of immunoglobulin and hormone shock therapy.
Outcomes: After 1 week, the symptoms of intestinal obstruction and MFS gradually improved. The patient was later discharged automatically for financial reasons. Six months after discharge, the patient was interviewed by telephone, and she had recovered.
Conclusion: To date, intestinal obstruction has rarely been reported as the initial symptom. In case of inconsistencies between the imaging examinations and clinical symptoms, neuroelectrophysiology and cerebrospinal fluid puncture should be performed, striving for timely detection and treatment.
Competing Interests: The authors have no conflicts of interest to disclose.
