1 | Horizontal Gaze Palsy, Facial Nerve Palsy, and Nystagmus Due to Dorsal Pontine Ischemia | 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Presented here are two patients with horizontal gaze and facial palsies due to stroke. The first patient is a 60-year-old man who presented with double vision and hemiparesis due to a right dorsal pontine ischemic stroke.... | Image/MovingImage | |
2 | Oculopalatal Tremor and One-and-a-Half Syndrome Due to Pontine Hemorrhage | 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 65-year-old man who was put on a blood thinner, and shortly thereafter experienced a midline pontine hemorrhage, which was more dense on the left side. Immediately afterwards, right hemiparesis and hemi-anesthes... | Image/MovingImage | |
3 | One-and-a-Half Syndrome Due to Pontine Hemorrhage | This is a 50-year-old woman who, while exercising in the gym, suddenly experienced vertigo, nausea, vomiting, tingling in the left arm, and diplopia. MRI demonstrated a brainstem hemorrhage that involved the right greater than left pons. Examination demonstrated a right horizontal gaze palsy due to ... | Image/MovingImage | |
4 | One-and-a-Half Syndrome, Facial Palsy, and Nystagmus Due to Dorsal Pontine Demyelination | This is a 16-yo-girl with oscillopsia and double vision. Exam showed inability to look to the left with either eye due to left nuclear 6th. There was also a left INO (horizontal gaze palsy + INO = one-and-a-half syndrome) from left MLF involvement and left lower motor neuron facial palsy due to fasc... | Image/MovingImage | |
5 | Pons: 6th and 7th Nerve Anatomy and the Central Segmental Tract | From this cross-section of the pons, the proximity of the 6th nucleus to the 7th nerve fascicles is apparent. This is the basis of the so-called facial colliculus syndrome, where an ipsilesional horizontal gaze palsy from a nuclear 6th lesion (usually related to stroke or demyelination) can be seen ... | Image |
