In cases of inadequate nutrition among individuals with dysphagia, nasogastric tube insertion is considered for nutritional supplementation. Typically, the complications of nasogastric tube insertion are not severe. In rare cases, however, nasal or nasopharyngeal injury caused by the self-knotting of nasogastric tubes can occur. This paper presents a case of spontaneous knotting of a nasogastric tube and its removal in a patient with aspiration pneumonia caused by dysphagia. This case shows that self-knotting must be considered when there is strong resistance during the removal of a nasogastric tube.
