Isolated ZIC4 antibodies in paraneoplastic cerebellar syndrome with an underlying ovarian tumor.

Abstract

OBJECTIVE:

To describe a patient with paraneoplastic cerebellar syndrome and the uncommon association of isolated ZIC4 antibodies and ovarian cancer.

DESIGN:

Case report and review of the literature.

SETTING:

Hospitalized care, follow-up in private practice.

PATIENT:

A 60-year-old woman with severe paraneoplastic cerebellar syndrome and an underlying ovarian adenocarcinoma.

INTERVENTIONS:

Neurological examination, lumbar puncture, laboratory tests, radiological imaging, and histological examination.

MAIN OUTCOME MEASURES:

Clinical course and titer of anti- ZIC4 antibodies in serum.

RESULTS:

Laboratory and cerebrospinal fluid tests revealed the isolated presence of ZIC4 antibodies. Screening results for small cell lung carcinoma were negative, while abdominal computed tomographic scan was suggestive of ovarian adenocarcinoma, which was confirmed by histological examination. Glucocorticosteroid administration and chemotherapy led to complete remission of paraneoplastic cerebellar degeneration.

CONCLUSION:

To the best of our knowledge, this is the first case of paraneoplastic cerebellar degeneration in a patient with isolated ZIC4 antibodies associated with ovarian adenocarcinoma.
