Prior to the paraesthesia onset, the patient experienced transient mild ataxia and left ocular pain with complete resolution at the time of presentation. Neurological exam revealed isolated right-sided sensory changes from his hand-to-elbow as well as foot-to-knee. No other focal neurological deficits were noted. MRI brain revealed a small left posterior infarct at the junction between the pons and midbrain. Dual-antiplatelet therapy was initiated and the patient experienced minimal paraesthesia improvement proximally over his 5-day hospital course. This case report highlights an acute brainstem stroke presenting with predominant hemisensory symptoms. Presentations of brainstem lesions can range from subtle, non-specific features to profound deficits. This case serves to emphasise the importance of performing a thorough clinical exam while maintaining a high index of suspicion for brainstem lesions.<\/jats:p>","DOI":"10.1136\/bcr-2019-230472","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T07:37:04Z","timestamp":1567064224000},"page":"e230472","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Pure sensory stroke due to brainstem lesion"],"prefix":"10.1136","volume":"12","author":[{"given":"Ryan","family":"McCreery","sequence":"first","affiliation":[{"name":"Graduate Medical Education, Orange Regional Medical Center, Middletown, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zoltan","family":"Fekete","sequence":"additional","affiliation":[{"name":"Neurology, Crystal Run Healthcare, Rock Hill, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,28]]},"reference":[{"key":"2025082802193466000_12.8.e230472.1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.15.1.76"},{"key":"2025082802193466000_12.8.e230472.2","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.23.7.983"},{"key":"2025082802193466000_12.8.e230472.3","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.28.9.1761"},{"key":"2025082802193466000_12.8.e230472.4","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410130327"},{"key":"2025082802193466000_12.8.e230472.5","doi-asserted-by":"crossref","first-page":"521","DOI":"10.1212\/WNL.60.3.521","article-title":"Transient eye and nose pain as an initial symptom of pontine infarction","volume":"60","author":"Doi","year":"2003","journal-title":"Neurology"},{"key":"2025082802193466000_12.8.e230472.6","doi-asserted-by":"crossref","first-page":"322","DOI":"10.1016\/j.ajo.2007.03.030","article-title":"\u201cSalt and pepper\u201d in the eye and face: a prelude to brainstem ischemia","volume":"144","author":"Conforto","year":"2007","journal-title":"Am J Ophthalmol"},{"key":"2025082802193466000_12.8.e230472.7","first-page":"213","article-title":"Brain stem infarction: clinical clues to localize them","volume":"1","author":"Sinha","year":"2000","journal-title":"JIACM"},{"key":"2025082802193466000_12.8.e230472.8","unstructured":"Martin JH .
