Presentation Transcript

  1. Case of the Month - October 2013 • 50 year old male with 2 week history of dysphagia and odynophagia. No trauma. • Investigations reveal: • Temperature 37.5 • WBC normal • C-spine X-rays reveal prevertebral soft tissue swelling. Case submitted by YoanKagoma, PGY2

  2. Contrast Enhanced CT of the Neck • What are the imaging findings? • What is the differential diagnosis? Diagnosis?

  3. Sagittal Soft Tissue and Bone Windows

  4. Axial Soft Tissue Window

  5. Coronal Soft Tissue Window

  6. Axial Bone Window

  7. Findings • Smooth soft tissue edema and swelling within the prevertebral soft tissues from C1-C4 • No evidence of peripheral enhancement. • Amorphous soft tissue calcifications surrounding the atlanto-axial joint.

  8. Differential Diagnosis • Retropharyngeal abscess? • Retropharyngeal effusion? • Perivertebralspace infection? • Other?

  9. Diagnosis • Findings are most in keeping with calcific tendonitis of the longuscolli muscle. • Infection or retropharyngeal abcess are less likely given that the patient is not febrile, has a normal white count, and the collection does not exhibit peripheral enhancement.

  10. Discussion • A rare diagnosis; first described by Hartley in 1964. • Clinical presentation: dysphagia, odynophagia, subacute neck pain, and low grade pyrexia. There may be preceding URTI or minor neck trauma. • Demographics: Most common amongst 30-60 year olds. No male/female predominance.

  11. Discussion • Pathophysiology: granulomatousand/or inflammatory reaction due to deposition of calcium hydroxyapatite crystals within the fibers of the longuscolli that insert into C1/C2. • Treatment: anti-inflammatory and analgesic medications. Incision and drainage is NOT required.

  12. Discussion The 3 imaging findings most suggestive of the diagnosis: • Amorphous calcifications in the prevertebral muscles, particularly C1-C2 • Inflammation with swelling of prevertebral muscles • Smoothly expanding retropharyngeal space edema Image from Offiah C & Hall E.
