Aseptic arthritis of the bilateral temporomandibular joint mimicking rheumatological diseases.
Initial laboratory tests showed serum C-reactive protein of 154 mg/L (0-5), ferritin of 1314 ng/mL (15-200), leukocyte count of 22.1 x [10.sup.3]/[micro]L (4-10), hemoglobin of 10.1 g/dL (10-17), and total bilirubin of 2.31 mg/dL (0-1.1). The test for rheumatoid factor was negative. Significant inflammatory processes were seen on magnetic resonance imaging in [T.sub.2] (Figure 1b) and necrotic areas in the right ramus of the mandible were also seen as a hypointense signal in [T.sub.2] (Figure 1c). Arthritis in the bilateral condylar head secondary to a sickle cell crisis was diagnosed after the analysis of the laboratory tests and images.
The patient was admitted to the hematology ward and received standard analgesia recommended for the treatment of severe pain consisting of nonsteroidal antiinflammatory drugs and parenteral opioid analgesia. The pain gradually subsided after four days of hospital stay, allowing progressive weaning from the analgesic treatment. Mouth opening amplitude improved substantially to 40 mm at six months.
[FIGURE 1 OMITTED]
Almost half of sickle cell patients experience orofacial pain. (1) Limb joint pain is common, but temporomandibular joint (TMJ) pain is rare. (2) Clinicians should be aware that aseptic arthritis may occasionally be caused by sickle cell disease. (3) The differential diagnosis should include avascular necrosis of the condylar head, manifestation of rheumatoid arthritis and juvenile rheumatoid arthritis in the TMJ, trauma and lupus arthritis of the TMJ. (4)
Laboratory tests and diagnostic imaging remain important for proper assessment due to the similarity of clinical manifestations of TMJ arthritis. Sickle cell disease may cause TMJ arthritis, and should be considered although rarely seen in the differential diagnosis of TMJ arthritis.
