Despite improvement with treatment, he developed bilateral leg weakness and numbness, ultimately diagnosed as peripheral neuropathy. Further investigations revealed a spectrum of haematological and neurological manifestations associated with B12 deficiency, challenging the typical illness script of pernicious anaemia. This report underscores the importance of recognising variations in clinical presentation and highlights the need for expanded illness scripts to guide accurate diagnosis and management.<\/jats:p>","DOI":"10.1136\/bcr-2024-260967","type":"journal-article","created":{"date-parts":[[2024,8,31]],"date-time":"2024-08-31T12:05:21Z","timestamp":1725105921000},"page":"e260967","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Challenging illness scripts: a case of pernicious anaemia and axonal neuropathy"],"prefix":"10.1136","volume":"17","author":[{"given":"Amara","family":"Ahmed","sequence":"first","affiliation":[{"name":"Internal Medicine, Florida State University College of Medicine, Tallahassee, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hussam","family":"Ammar","sequence":"additional","affiliation":[{"name":"Internal Medicine, Florida State University College of Medicine, Tallahassee, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald","family":"Mageau","sequence":"additional","affiliation":[{"name":"Florida State University College of Medicine, Tallahassee, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,8,31]]},"reference":[{"key":"2025082703121440000_17.8.e260967.1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2929.2005.02127.x"},{"key":"2025082703121440000_17.8.e260967.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(12)61041-6"},{"key":"2025082703121440000_17.8.e260967.3","doi-asserted-by":"crossref","first-page":"2040","DOI":"10.1056\/NEJMx120025","article-title":"Case 13-2012: A 62-Year-Old Man with Paresthesias, Weight Loss, Jaundice, and Anemia","volume":"366","year":"2012","journal-title":"N Engl J Med"},{"key":"2025082703121440000_17.8.e260967.4","doi-asserted-by":"crossref","first-page":"202","DOI":"10.14740\/jh889","article-title":"Severe Vitamin B12 Deficiency Mimicking Microangiopathic Hemolytic Anemia","volume":"10","author":"Hassouneh","year":"2021","journal-title":"J Hematol"},{"key":"2025082703121440000_17.8.e260967.5","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1016\/j.transci.2018.01.003","article-title":"Cobalamin deficiency presenting with thrombotic microangiopathy (TMA) features: A systematic review","volume":"57","author":"Tran","year":"2018","journal-title":"Transfus Apher Sci"},{"key":"2025082703121440000_17.8.e260967.6","first-page":"229","article-title":"Neurologic Aspects of Cobalamin Deficiency","volume":"70","author":"Healton","year":"1991","journal-title":"Medicine (Abingdon)"},{"key":"2025082703121440000_17.8.e260967.7","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.60.9.1296"},{"key":"2025082703121440000_17.8.e260967.8","doi-asserted-by":"crossref","unstructured":"Green R , Allen LH , Bj\u00f8rke-Monsen A-L , et al .
