INTRODUCTION: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is an autoinflammatory disorder without standardized treatment. Janus kinase (JAK) inhibitors can block a range of cytokines and might possess significant anti-inflammatory activity. Here, we report the first case of efficacious treatment of refractory SAPHO syndrome with the JAK inhibitor tofacitinib. CASE PRESENTATION: A 44-year-old woman presented with arthralgia in the right wrist and complained of having difficulty in doing housework...

Calciphylaxis is a poorly understood condition involving vascular calcification and thrombosis that leads to skin necrosis. Unfortunately, a noninvasive definitive test for calciphylaxis does not currently exist, and diagnosis relies on clinical symptoms and risk factors. Imaging can help guide diagnosis of this rare disorder. We present a pathology-proven case of calciphylaxis and the corresponding imaging findings seen on bone scintigraphy.

Hypertrophic pulmonary osteoarthropathy (HPOA) is a paraneoplastic manifestation of gastric and, more frequently, lung carcinomas. It is characterized by extremity pain, clubbing, arthritis and periostitis of the long bones. Periostitis is the hallmark of HPOA and can be revealed with bone scintigraphy. Whole-body bone scintigraphy (WBBS) is very sensitive during the active lesion period and WBBS findings usually precede that of plain radiography. WBBS can also show improvement in the first 6 months following treatment, thus making it an important technique in the management and follow-up of these patients...

Kohler disease refers to childhood onset avascular necrosis of the navicular bone. Hybrid SPECT-CT bone scintigraphy offers both functional and anatomic details in a single acquisition if radiography is non-diagnostic in a limping child. We present the case of a 7 year-old child with persistent post-traumatic left foot pain. Tc99m MDP bone SPECT-CT scan demonstrated characteristic anatomic features of left navicular avascular necrosis.

Bone scintigraphy has been used for the diagnosis of early-stage temporomandibular joint (TMJ) osteoarthritis (OA) owing to its high sensitivity. However, the diagnostic value of bone scintigraphy may be compromised when applied to patients in an age range with high bone metabolism rates. The aim of this study was to investigate the validity of bone scintigraphy as an appropriate diagnostic modality for TMJ OA. A total of 406 subjects (145 male, 261 female; age range 14-87 years) were selected, and all subjects underwent both bone scintigraphy and computed tomography (CT)...

One of significant challenges faced by diabetologists, surgeons and orthopedists who care for patients with diabetic foot syndrome is early diagnosis and differentiation of bone structure abnormalities typical of these patients, i.e. osteitis and Charcot arthropathy. In addition to clinical examination, the patient's medical history and laboratory tests, imaging plays a significant role. The evaluation usually begins with conventional radiographs. In the case of osteomyelitis, radiography shows osteopenia, lytic lesions, cortical destruction, periosteal reactions as well as, in the chronic phase, osteosclerosis and sequestra...

A vast spectrum of lower limb bone and joint disorders (hip, knee, ankle, foot) present with a common clinical presentation: limping. Too often this symptom generates an inefficient cascade of imaging studies. This review attempts to optimise the diagnostic effectiveness of bone scintigraphy using the hybrid SPECT/CT technique in relation to the diagnostic clues provided by other imaging modalities, discusses the appropriate clinical indications, optimal scintigraphic procedures and illustrates updated image pattern-oriented reporting...

Axial sesamoiditis or osteitis of the proximal sesamoid bones (PSBs) in the horse is described as a rare condition. The cause remains unknown and speculative, with vascular, infectious, and traumatic aetiologies implicated. It is specifically associated with injury of the palmar or plantar ligament (PL), also known as the intersesamoidean ligament. Imaging findings are generally rewarding and radiological changes are typical, if not pathognomonic, for the condition. Lesions consist of bone lysis at the apical to mid-body axial margins of the PSBs, with variable degrees of joint effusion...
