UNASSIGNED: Monoarthritis, defined as inflammation of a single joint, requires a thorough physical examination in @entity1 , as @entity158 may be lacking in 10% to 30% of cases and joint stiffness may be the only symptom. Joint aspiration is a crucial diagnostic tool that remains markedly underused. Joint aspiration may be unnecessary, however, when the family history or other investigations provide the diagnosis. Radiographs of the involved joint may supply information on the severity of the lesions. In doubtful cases and in @entity1 with @entity4841 , B-mode and Doppler ultrasound or magnetic resonance imaging (MRI) may confirm the presence of @entity603 . Although suspected @entity5414 is an emergency and occurs frequently, particularly before 2  years of age, acute monoarthritis is often a post-infectious manifestation and therefore associated with a good outcome. @entity3001 should be sought, particularly when a lower limb joint is involved, as tick bites often go unnoticed. @entity102 is very often a manifestation of @entity4932 ( @entity4932 ), which exists as several variants. @entity4932 is a specifically @entity2720 , whereas the other patterns of @entity4932 have corresponding forms in adults, despite a number of specific features due to their onset during childhood. Tests for antinuclear antibodies should be performed routinely in @entity1 with monoarthritis persisting longer than 3  weeks. A decline in general health or a fever should suggest @entity625 revealing @entity5 , which is a @entity1503 in most cases. Finally, suggestive symptoms are often present in @entity1 with less common causes such as auto-inflammatory diseases and connective tissue diseases.
