Abstract: Guillain–Barré syndrome (GBS) is an acute inflammatory polyradiculoneuropathy, often triggered by an infectious prodrome. It usually presents with ascending motor weakness and areflexia, but atypical forms can be challenging to diagnose. This case report highlights the presentation of a 53-year-old male with an atypical form of GBS, characterized by bifacial weakness, sensory ataxic gait, and radicular back (girdle-like pain around the waist) pain without classic ascending paralysis. The diagnosis was supported by albuminocytological dissociation in cerebrospinal fluid and abnormal nerve conduction studies. Early diagnosis and prompt treatment with intravenous immunoglobulin led to significant recovery, with some residual tingling and numbness on both feet after 1 month of discharge.
Gama et al. (2026) studied this question.
