OBJECTIVES: To assess the frequency, features, and outcome of excruciating lumbar, dorsal, and/or thoracic pain following injections of local corticosteroids in rare instances. METHODS: A questionnaire mailed to 500 French rheumatologists. RESULTS: Three hundred and eighteen cases were reported by 92 rheumatologists (one event per 8000 injections or 6.5 years of practice), following injections into lumbar epidural space (39%), an upper limb (30%), a lower limb (mostly the heel) (24%), or other locations (7%), of cortivazol (67%), hydrocortisone (25%), betamethasone (7%), or paramethasone (1%). Symptoms occurred 1-5 min (78%) or less than 1 min (22%) after injection, and highly acute axial pain usually lasted for less than 5 min (34%) or 5-15 min (51%). In addition to pain in lumbar (84%) and/or dorsal regions (25%) [often preceded or associated with thoracic pain (36%)], other signs were: anxiety (87%), shortness of breath (64%), facial flushing (64%), diffuse sweating (41%), agitation (29%), transient cough (23%), abdominal pain (20%), transient hypertension (15%), paleness (10%), hypotension (8%), diarrhoea (3%) and headache (3%). None of these patients was known to be allergic, and urticaria developed in only 2%. Outcome was favourable in all cases (even though 4/318 patients were transiently hospitalised) with an overall duration of 25 +/- 71 min. Another injection was performed later in 146/318 cases (46%), but Tachon's syndrome recurred in only 20 of these 146 patients (14%). CONCLUSION: The outcome of this impressive syndrome seems excellent. Tachon's syndrome might be the venous counterpart of Nicolau's syndrome (injection of corticosteroids in an artery).
