Rationale: Salmonella is a common etiological agent behind the tropical fever syndrome in the Indian subcontinent. Its prevalence in India remains high due to a lack of proper sanitation services in large parts of the country. Its neuropsychiatric manifestations is rare and the understanding on their pathophysiology is still poor. Patient concerns: A 19-year-old male, presented with a 10-day history of altered mental status, high-grade fever and violent behaviour. 2 Days prior to admission, he developed decreased responsiveness and a muttering delirium with self-talking. Diagnosis: Coma vigil secondary to salmonellosis. Interventions: Intravenous ceftriaxone and dexamethasone. Outcomes: The resolution of the coma vigil and the associated Salmonella infection were observed; however, the patient developed residual mutism. Lessons: The atypical presentation of a globally obtunded state followed by mutism in typhoid coma in this case should be brought to the attention of clinicians worldwide. Additionally, the enduring speech limitations and potential psychiatric consequences may be linked to the prolonged duration of the infection.

Typhoid fever (enteric fever), caused by Salmonella enterica subsp. enterica serovar Typhi (S. Typhi), is a public health problem especially in South Asia and sub-Saharan African countries, while incidence remains low in most other parts of the world, where the disease is primary related to recent travel to endemic countries or contact with chronic carriers. The diagnosis of typhoid fever is challenging in endemic countries, often also low- and middle- income countries (LMIC), due to the poor sensitivity/specificity of available serologic tests and lack of adequate infrastructure for blood cultures. We report the case of an 18-year-old male patient with a 21-day history of right-sided abdominal pain, malaise, headache, intermittent fever and watery diarrhea. Contrast-enhanced abdominal computed tomography (CT) exhibits thickening of the terminal ileum, cecum and ascending colon with mesenteric lymphadenopathy. Laboratory findings indicate elevated transaminases, positive blood culture to S. Typhi and a positive Widal test to S. Paratyphi A, B and S. Typhi H (flagellar) antigens. A diagnosis of complicated typhoid fever was made. Following a 13-day regimen of ceftriaxone, all symptoms resolved. Few reports have been made about CT manifestations in patients with typhoid fever. While CT can aid in diagnosis, it is particularly important for identifying complications of typhoid fever such as perforation, bleeding and abscess formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
