Medical Imaging Analysis Report

I. Radiological Findings

Based on the provided chest CT, spinal and limb X-rays, as well as cranial imaging (including panoramic radiography of the maxillofacial region), the following main characteristics are observed:

1. Thoracic, dorsal, and paraspinal regions: CT and 3D reconstruction reveal cord-like or lump-like areas of increased density within the vertebral bodies and paravertebral muscular regions, resembling bone tissue and suggesting significant heterotopic ossification. In some areas between the ribs and vertebral bodies, exostosis can also be seen, leading to restriction of the thoracic cage.
2. Cervical region and skull: Sclerotic changes or bone-like proliferations are observed in the right occipital region of the posterior skull; imaging of the mandible suggests a marked reduction in the range of motion of the temporomandibular joint, possibly indicating heterotopic calcification in the joint or surrounding soft tissues.
3. Limbs: Bilateral foot X-rays show that the first toe (hallux) is significantly shortened and deviated laterally, with only a single (or fused) phalanx remaining, consistent with the typical congenital anomaly of the first toe (shortened and valgus).
4. Other soft tissue ossifications: Multiple high-density lesions with bone-like density are seen in the scapular region, paraspinal muscles, and soft tissues of the back. Their well-defined margins are consistent with imaging findings of heterotopic ossification.

II. Potential Diagnoses

1. Fibrodysplasia Ossificans Progressiva (FOP) - This disease is an autosomal dominant genetic disorder characterized by progressive ossification of soft tissues such as muscles, fascia, and ligaments. - The classic “stone man syndrome” shows patchy or cord-like ossifications within muscles or fascia on imaging. - Congenital malformation of the great toe is a key diagnostic feature. - Imaging findings show a high degree of consistency with clinical history (difficulty opening the mouth, multiple round or cord-like ossifications), suggesting this diagnosis.
2. Other rare heterotopic ossification disorders - For instance, Progressive Osseous Heteroplasia, etc., but most do not present the typical first-toe malformation.
3. Recurrent muscle or fascial calcification/ossification - Such as post-traumatic or post-infectious calcifications, usually associated with a history of trauma and lacking the characteristic bilateral toe deformities.

III. Final Diagnosis

Combining the onset at 10 years of age, progressive difficulty opening the mouth, abnormal soft tissue ossifications in the back and head, and bilateral congenital malformation of the first toe (short and valgus), the most fitting diagnosis is:

Fibrodysplasia Ossificans Progressiva (FOP).

This disease has highly specific clinical and radiological features, including congenital hallux deformities and progressive heterotopic ossification within soft tissues.

IV. Treatment Plan and Rehabilitation

1. Treatment Strategy

• Conservative management: Currently, there is no curative treatment. Efforts should be made to avoid trauma, intramuscular injections, and unnecessary surgical procedures to prevent new areas of ossification.
• Pharmacological intervention: During active inflammatory periods or early in the formation of new ossification lesions, a short course of corticosteroids (e.g., prednisone) may help reduce acute inflammation. Bisphosphonates (such as etidronate) or other calcification inhibitors may also be used to slow the progression of ossification.
• Supportive therapy: For functional impairments resulting from established heterotopic ossifications, physical therapy and orthotic support can be provided.

2. Rehabilitation and Exercise Prescription

Because FOP patients are prone to further ossification in joints and soft tissues, any inappropriate or forceful therapeutic measures may exacerbate ossification. Rehabilitation should be carefully managed, focusing on safety and a gradual approach:

• Frequency: Recommended 2-3 times per week, adjusted according to the patient’s tolerance and stability of the condition.
• Intensity: Emphasize mild passive or active range-of-motion exercises, avoiding pain or marked discomfort to prevent new ossification.
• Time: Each session should start with 5-10 minutes of exercises, gradually increasing to 15-20 minutes while monitoring the patient’s subjective experience.
• Type: Primarily range-of-motion maintenance exercises, gentle stretching, and mild muscle strengthening (such as low-resistance band exercises or isometric training). Strenuous or high-impact activities must be strictly avoided.
• Progression: Increase intensity and duration gradually, based on stable disease status. Monitor closely for any new heterotopic ossification or pain responses.

If the thoracic cage or cervical spine is involved, breathing exercises (such as deep breathing) should be performed with caution to avoid excessive stretching of the chest and back muscles.
