Miosis, ptosis, and ipsilateral facial anhidrosis are normally present in Horner’s syndrome. Pathologies which show central, preganglionic and postganglionic residence in sympathetic chain are present in its etiology. A 3-month-old girl baby was admitted to our clinic for ptosis in the left eye. Heterochromia, ptosis in the left eye, myosis and, ipsilateral anhidrosis were detected in her examination. In view of these findings, it seemed possible that her disease could be congenital Horner’s syndrome. Brachial plexus injury due to birth trauma plays a major role in the etiology of congenital Horner’s syndrome. There was not any birth trauma history in our patient. The patient was diagnosed to have neuroblastoma as a result of etiologic tests. In conclusion, Horner’s syndrome can be the presenting sign of childhood neuroblastoma. Therefore, it is advisable to examine the oculosympathetic system in detail in order to leave out any underlying serious disorder.
