“…Considering the CT images, the consolidated bone region would have devitalized or reduced vitality, possibly fibrosis with lower blood supply. Partial bone resorption and reactive fibrosis showed a mixed image of bone consolidation (low intensities on T1 WI and heterogeneous hyper-intensities on T2 WI), as Kaneda has previously suggested [13,21]. Moreover, the homogeneous hyper-intensities of T2 WI may be mild bone marrow inflammation considering the clinical symptoms of ORN.…”

Radiation therapy (RT) plays a significant role in the management of head and neck malignancies. This study aimed to review the clinical symptoms and various imaging findings of osteoradionecrosis (ORN) and provide a clinical perspective on the development of ORN. The retrospective cohort was composed of 57 sites in 54 patients who had a history of RT and suspected ORN and 48 sites in 45 patients who were confirmed to have ORN. Image analyses included computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET)/CT, bone scintigraphy, and single-photon emission CT (SPECT). The irradiated tissue was damaged by RT, and the extent of damage was correlated with clinical symptoms. The bone marrow showed sclerotic changes and the devitalized bone showed bone resorption after invasive stimulation. Chronic trismus and pathological fracture are considered severe conditions, typically occurring in the last stage of ORN. Furthermore, neurological symptoms were an important sign of tumor recurrence, since diagnostic imaging was difficult. The possible treatment options vary depending on the stage of ORN. We speculate that bone sclerosis reactions and bone resorption are sequential reactions that seem to be protective measures of the bone to radiation injury.

“…Axial and coronal images were obtained. The classification of images and comparison with pathological findings were performed according to a previous study by Ariji et al [21]. Briefly, T1 WI were classified into two patterns-low and no change.…”

“…The CT features in our cases were consistent with the findings as described by Kadom et al (Figure ). Magnetic resonance imaging examination which was done in the first case scenario was to differentiate osteomyelitis from other diseases with similar clinical symptoms; as MRI images of osteomyelitis have been characterized by changes in signal intensity of the bone marrow, such as decrease on T1‐weighted images and increase on T2‐weighted images (Figure ).…”

Background Chronic recurrent forms of osteomyelitis of the mandible with their morbid clinical course have long been considered a challenge to maxillofacial surgeons in terms of both diagnosis and treatment. Various classifications and treatments have been established through the ages to define and manage the inflammatory symptoms occurring in adults and children. This paper discusses two such entities occurring in an adult and a child, highlighting the diagnostic and treatment challenges of recurrent osteomyelitis. Methods A thorough workup which included clinical, radiographic, blood investigations was done, followed by administration of antibiotics and anti‐inflammatory with or without surgical debridement/adjuvant therapies. Correlation of our findings and treatment plan was done with evidence‐based literature and practice. Results Complete resolution of symptoms with radiographic evidence was achieved in both the cases. In the recurrence period, long‐term steroids, NSAIDs, antibiotics resulted in better outcomes. Conclusion The evidence‐based protocol for osteomyelitis stresses on short inpatient stays predicated on efficient literature. Thorough clinical and radiographic evaluation with aggressive medical management and surgical intervention when necessary can result in longer symptom‐free periods. Thus understanding the disease, recurrence pattern and response to therapy is essential.
