Purpose To report a case of one‐and‐a‐half syndrome caused by pontine metastasis of breast cancer. Methods A 46‐year‐old woman with breast cancer presented with binocular diplopia for 2 month. She had previously been diagnosed with invasive ductal carcinoma in her left breast and had known metastases to the lung. She had undergone a modified radical mastectomy and chemotherapy. Her binocular horizontal diplopia worsened progressively and accompanied ipsilateral facial parethesia. Results Her visual acuity was 10/20 in both eyes and no abnormal findings were detected on anterior segment exam. Her both eyes were fixed in the midline on attempted right gaze. On attempted left gaze, only left eye abduction was preserved and vertical eye movements were normal. Brain MRI revealed that variable sized nodular enhancing lesions at right pons, both cerebral hemispheres, left globus pallidus, right temporal lobe and upper portion of cerebellar vermis. Conclusion Breast cancer is known to be the second most common cause of brain metastasis. We should pay attention to the patient’s medical history who presenting diplopia
