Atypical Presentation of Gall Bladder Adenocarcinoma as Paraneoplastic Myeloneuropathy

Paraneoplastic neurologic syndromes are a rare, heterogeneous group of complications associated with malignancy, unrelated to direct tumor invasion or metastasis. They are the remote effects of a malignancy owing to immune-mediated reaction toward the antigens that are common to both the malignant and normal cells. Few paraneoplastic syndromes are reported with gall bladder cancer. However, neurological symptoms are infrequent. Here we share an interesting case of adenocarcinoma of gall bladder with initial presentation as a paraneoplastic noncompressing myeloneuropathy.
