A 72-year-old male presenting with mild throat discomfort with a prominent bony hard swelling on the posterior pharyngeal wall that was found to be due to florid osteophyte formation involving the anterior cervical spine.
A 72- year-old male presented to the ENT department with complaints of throat discomfort. There was no associated dysphagia, respiratory symptoms or complaints of neck stiffness or pain. He was a diet controlled diabetic, and on treatment for hypertension and hypercholestrolemia. The only abnormality found on ENT examination was a marked smooth bony protuberance in the midline on the posterior oro-pharyngeal wall. A lateral cervical spine radiograph showed a ‘flowing’ ossification along the anterior margins of the cervical vertebrae extending from C2 to C6.
Diffuse Idiopathic Skeletal Hyperostosis (DISH) or Forestier’s Disease is a non- inflammatory skeletal disease characterised by the ligamentous calcification of the anterolateral spine. It has marked predilection for the axial skeleton, but can involve peripheral sites such as the peripatellar ligaments, the Achilles tendon insertion, plantar fascia and olecranon. Thoracic involvement is most common and occurs in 99% of cases, while cervical involvement occurs in 75%. It is more common and severe in men than women. However the aetiology remains unknown but hyperinsulinemia with or without diabetes, obesity, hyperuricemia, dyslipidemia, hypertension, coronary artery disease and the prolonged use of isoretinol are considered to be significant risk factors. Patients with DISH are usually asymptomatic but can present with neck stiffness and pain, dysphagia, hoarseness, foreign body sensation or even stridor (3). The diagnosis is made solely on the radiographic appearances and abnormalities using the criteria described by Resnick and Niwayama(2) which are a) the presence of flowing calcification and ossification along the anterolateral aspect of at least four contiguous vertebral bodies with or without associated localised pointed excrescence at the intervening vertebral body-disc junctions b)a relative preservation of intervertebral disc height of the involved vertebral segments and the absence of extensive radiographic changes of degenerative disc disease, including the vacuum phenomenon and vertebral body marginal sclerosis and c) the absence of apophyseal joint bony ankylosis and sacro-iliac joint erosion, sclerosis or bony fusion. The treatment of DISH is essentially conservative and surgical removal of hyperostosis is only considered if symptoms are significant.
Diffuse Idiopathic Skeletal Hyperostosis (DISH) (Forestier’s Disease)
Based on the provided lateral cervical spine X-ray, there is a notable bony spur-like proliferation and calcification in the anterior longitudinal ligament region (i.e., the anterolateral aspect of the vertebral bodies). It presents as a continuous “flowing” manifestation, involving multiple segments of the cervical vertebrae. The adjacent intervertebral spaces appear relatively preserved, with no obvious narrowing of the disc spaces or significant disc degeneration. No clear ossification of the posterior longitudinal ligament or obvious facet joint fusion is observed. Overall, the images are consistent with non-inflammatory, extensive osteophyte formation. Clinically, the patient presents with mild pharyngeal discomfort, and a hard, bony protrusion can be palpated on the posterior pharyngeal wall, corresponding to the location of the anterior vertebral osteophytes as shown on the imaging.
Considering this 72-year-old male patient’s age, clinical symptoms (throat discomfort, palpable hard bony prominence on the posterior pharyngeal wall), and imaging findings of multi-segmental, “flowing” osteophyte formation along the anterolateral cervical vertebrae with relative preservation of the intervertebral disc spaces, the most likely diagnosis is: Diffuse Idiopathic Skeletal Hyperostosis (DISH/Forestier’s Disease).
If there is any uncertainty, further assessment via CT 3D reconstruction or MRI can be performed to evaluate soft tissue and potential tracheoesophageal compression. Additionally, ENT or endoscopic evaluation may be warranted to clarify the extent of esophageal involvement and compression.
In cases of mild symptoms or after surgical stabilization, a gradual rehabilitation program can be initiated. Following the FITT-VP principle:
Rehabilitation programs should be individualized, considering the patient’s specific condition (e.g., comorbid cardiovascular issues, osteoporosis, or other metabolic disorders) to avoid secondary injuries due to overexertion. If severe pain or discomfort occurs, exercise should be stopped immediately and medical advice sought.
This report is a reference-based analysis relying on available imaging and history and cannot replace an in-person consultation or professional medical opinion. Specific treatment and rehabilitation plans should be determined by specialized clinical physicians based on a comprehensive evaluation of the patient’s actual condition.
