Voriconazole-induced periostitis in a patient with HIV treated for coccidioidomycosis meningitis.

Voriconazole-induced periostitis is a rare adverse effect in patients on long-term therapy, characterised by periosteal inflammation and associated bony pain. The accompanying lab abnormalities (elevated serum alkaline phosphatase and fluoride) and characteristic imaging findings (uptake of radionuclide tracer on nuclear bone scan) are critical for diagnosis. The disease process is thought to be secondary to excess fluoride from voriconazole which stimulates bone formation and decreases osteoclast bone resorption. Management includes stopping voriconazole and switching to another agent.

Florid reactive periostitis of the clavicle: A case report and literature review.

RATIONALE: Florid reactive periostitis (FRP), a rare reactive bone lesion, typically presents in the short tubular bones of the extremities, with infrequent occurrences in the long tubular bones. This report discusses a unique case of FRP in the clavicle, managed through comprehensive lesion debridement and bone grafting, yielding positive results over a 3-year duration. PATIENT CONCERN: A 25-year-old male presented with a discernible mass at the left sternal end of the clavicle, discovered incidentally 2 weeks prior. The patient exhibited no clinical signs of inflammation, pain, sinus tract, or suppuration. DIAGNOSIS: Initial pathological examination of the local excision suggested benign lesions, although malignancy could not be ruled out. A definitive diagnosis of clavicular FRP was reached post complete lesion resection, with supporting evidence from postoperative pathology, imaging, and clinical symptoms. INTERVENTION: The left clavicle was reconstructed through an open surgical procedure involving total mass removal and ipsilateral extraction of an iliac bone of suitable dimensions. This was implanted into the clavicular bone defect and internally fixed with a plate. OUTCOMES: Three years of consecutive follow-up revealed no recurrence of hyperplasia, absence of mass or tenderness at the left sternal end of the clavicle, and unimpaired function of adjacent joints. LESSONS: The primary clinical challenge with FRP is its diagnosis. While pathological diagnosis remains crucial, it is also important to incorporate imaging and clinical symptoms for a comprehensive assessment. Complete mass excision may offer specific benefits in distinguishing FRP from its malignant counterparts.

[Bilateral periostitis and arthritis: about a case of hypertrophic osteoarthropathy]. / Périostite bilatérale et polyarthrite : à propos d'un cas d'ostéoarthropathie hypertrophique pneumique.

We report the case of a 67-year-old female patient presenting swelling of the hands and feet and pain in both legs. Clinical examination and bone scintigraphy identify the triad "digital clubbing - arthritis - bilateral periostitis of the long bones", leading to a diagnosis of hypertrophic osteoarthropathy, a syndrome usually associated with pulmonary neoplasia. The thoracic CT-scan, followed by a biopsy, effectively diagnosed a right upper lobe adenocarcinoma. Surgical treatment of the neoplasia allowed the resolution of the clinical complaints and the pathological scintigraphic findings.

Nous rapportons le cas d'une patiente de 67 ans présentant des gonflements des mains et des pieds ainsi que des douleurs des deux jambes. L'examen clinique et la scintigraphie osseuse identifient la triade «hippocratisme digital - arthrites - périostite bilatérale des os longs¼, permettant de poser un diagnostic d'ostéoarthropathie hypertrophique, un syndrome habituellement associé à une néoplasie pulmonaire. Le scanner thoracique, suivi d'une biopsie, ont en effet diagnostiqué un adénocarcinome localisé au niveau du lobe supérieur droit. La prise en charge chirurgicale de la néoplasie a permis la résolution des plaintes cliniques et de l'aspect scintigraphique pathologique.

Spectrum of voriconazole-associated periostitis in clinical characteristics, diagnosis and management.

PURPOSE: Previous knowledge about the relationship between voriconazole exposure and periostitis was mainly based on limited case reports and few retrospective studies. The purpose of this study was to assess the clinical characteristics, diagnosis and management of voriconazole-associated periostitis. METHODS: Case reports and case series from 1998 to November 30, 2021 on periostitis induced by voriconazole were collected for retrospective analysis. RESULTS: Forty four patients (18 male and 26 female) from 34 studies were included in total. The median age was 58 years (29-74). The majority of patients had undergone organ transplantation (50.0%) or suffered from hematologic malignancy (31.81%). The median onset time of symptoms was 6 months after the start of voriconazole. The most common initial symptom was diffuse skeletal pain (68.28%) which can be severe and even disabling (66.7%). Ribs (37.21%), femurs (32.56%), scapulae (25.58%), humerus (23.26%), and clavicle (23.26%) were the common involved locations. Most cases were accompanied by different degrees of elevated serum alkaline phosphatase and fluoride level, while some presented with elevated bone-specific alkaline phosphatase. The main radiological features included periosteal reaction and multifocal high radiotracer uptake on bone scintigraphy. The formation of new bone was characterized with bilateral, irregular, nodular, as well as high density. The resolution of symptoms was observed with discontinuation of voriconazole in all patients, of whom 18 patients (52.94%) were relieved within a week. Itraconazole, posaconazole or isavuconazole were safe alternatives to voriconazole in voriconazole-induced periostitis. CONCLUSION: Voriconazole-induced periostitis is an infrequent complication characterized by bone inflammation involving one or multiple skeletal areas. Bony pain, elevated serum alkaline phosphatase as well as fluoride level are suspicious signs during voriconazole treatment.

Voriconazole-induced periostitis.

Voriconazole is a fluorinated drug from the triazole group that is widely used in the prophylaxis and treatment of fungal infections in immunosuppressed patients. Chronic use of this medication can generate, as an adverse effect, a multifocal, asymmetric, diffuse and nodular periosteal reaction, associated with severe and disabling skeletal pain and elevated alkaline phosphatase and serum fluoride. Radiography is the imaging technique of choice for periostitis diagnosis. In general, clinical manifestations and radiographic findings disappear, when the drug is discontinued. We report the clinical case of a 44 year-old woman diagnosed with acute myeloid leukemia, who developed an invasive fungal infection treated with voriconazole after a stem cell transplant. Nine months after starting antifungal treatment, she manifested symptoms and radiological signs compatible with periostitis. Due to clinical suspicion, we decided to suspend voriconazole, with consequent resolution of clinical manifestations and radiological findings.

Pseudoparalysis of parrot - Re-emergence of the great mimicker.

We present the case of a 2-month-old adopted female seeking evaluation in the pediatric emergency department due to a one-day history of decreased right arm movement and fussiness. The physical exam was largely unremarkable with the exception of decreased spontaneous movement of the right upper extremity, obvious discomfort with passive movement and subtle edema of the forearm. Because of concern for non-accidental trauma, plain films were obtained which revealed no signs of traumatic injury. Subsequently, a broader investigation ensued with infectious etiologies in mind. Laboratory evaluation demonstrated anemia, transaminitis, and elevated inflammatory markers. These abnormalities led to the consideration of congenitally acquired infections, specifically syphilis, and serologies were confirmatory. Ultimately, the infant was diagnosed with Pseudoparalysis of Parrot - a rare musculoskeletal manifestation secondary to painful syphilitic periostitis. As Emergency Medicine physicians, it is important to be aware of the growing burden of syphilis infection and reacquaint ourselves with its numerous presentations in the young infant.

Psoriatic onycho-pachydermo periostitis (POPP): a case report treated successfully with IL-17 blockade and a literature review on characteristics, pathogenesis, and treatment.

Psoriatic onycho-pachydermo periostitis (POPP) is characterized by psoriatic onychodystrophy, connective tissue thickening, and periostitis of the distal phalanges (DPs), producing a drumstick-like deformity. Our aim was to present the first case of POPP treated successfully with an IL-17 inhibitor, perform a literature review of its characteristics and treatment, and explore the possible pathogenesis. We conducted a systematic review of previously presented POPP cases. We present a patient with methotrexate (MTX)-resistant treatment POPP, who had significant resolution of symptoms and inflammatory lesions on post-treatment MRI with secukinumab 150 mg. We also identified 31 cases of POPP (27 males; mean age 44.9 years) in the literature review. There was great toe involvement in 24 cases, and distal interphalangeal (DIP) involvement in 14 cases, with frequent radiographically evident damage. Seventeen of 31 patients received systematic treatment other than biologics, mostly MTX, with no satisfactory results. Anti-TNF agents were used successfully in 5 cases, mostly after disease modifying anti-rheumatic drug (DMARD) failure. Imaging studies in nail psoriasis and DIP psoriatic arthritis have shown an anatomical link among the nail, the DP bone, and the DIP joint entheses, suggesting that POPP may be a subtype of nail disease with excessive involvement of DP tissues (nail, soft tissue, enthesis, and bone). IL-17 inhibition could be an alternative therapeutic option in DMARD-resistant cases of POPP. Conventional treatment achieves modest success, but anti-TNF agents appear to be much more effective. Based on imaging studies, POPP may be a particular subtype of nail disease.

Fibular Tip Periostitis: New Radiographic Sign Predictive of Chronic Peroneal Tendon Subluxation-Dislocation in Pes Planovalgus.

BACKGROUND. Tearing of the superior peroneal retinaculum is a known cause of peroneal tendon subluxation-dislocation. However, with the exception of cortical avulsions at the fibular attachment, superior peroneal retinaculum injury and subsequent peroneal tendon subluxation-dislocation are typically radiographically occult. OBJECTIVE. The purpose of this study was to evaluate the previously undescribed association between radiographic fibular tip periostitis and MRI evidence of peroneal tendon subluxation-dislocation in patients with hindfoot valgus. METHODS. Thirty-five patients with radiographic fibular tip periostitis and 35 ageand sex-matched individuals without periostitis were selected from among 220 consecutively registered patients with hindfoot valgus who had undergone both ankle radiography and MRI. Studies were retrospectively assessed by two musculoskeletal radiologists in consensus and by two additional blinded radiologists independently for the presence of peroneal tendon subluxation-dislocation, presence of subfibular impingement, and hindfoot valgus angle measurements. Interobserver agreement and accuracy, sensitivity, and specificity in the detection of fibular periostitis, peroneal tendon subluxation-dislocation, and subfibular impingement were calculated, and Fischer exact, Mann-Whitney, kappa coefficient, and intraclass correlation tests were performed. RESULTS. Both the consensus and the two independent interpretations showed that the frequency of peroneal tendon subluxation-dislocation was significantly greater in the group with periostitis (62.9%, 65.7%, and 85.7%) than in the group without periostitis (5.7%, 0%, and 14.3%) (p < .001). The finding of periostitis was specific and highly sensitive for predicting peroneal tendon subluxation-dislocation. The frequency of subfibular impingement was also statistically higher in the group with periostitis than in the group without it (p < .001). The hindfoot valgus angle was statistically larger in the group with periostitis than in the control group (p = .01-.002) and among patients with versus those without peroneal tendon subluxation-dislocation (p = .002 to p < .001). The blinded readers had substantial or almost perfect agreement on all imaging interpretations (concordance rate, 82.9-95.7%; κ = 0.66-0.91). CONCLUSION. The radiographic finding of fibular tip periostitis in patients with hindfoot valgus can be a predictor of peroneal tendon subluxation-dislocation and may also suggest advanced hindfoot valgus and subfibular impingement. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. CLINICAL IMPACT. Chronic undiagnosed peroneal tendon subluxation-dislocation can be a persistent cause of lateral ankle pain, leading to further degeneration and the possibility of complete peroneal tendon tears. Distal fibular periostitis in patients with hindfoot valgus can be a reliable radiographic indicator of this entity and may suggest the presence of subfibular impingement.

Imaging features of periostitis as a manifestation of IgA vasculitis: A case report.

INTRODUCTION: Periostitis in systemic vasculitis is very rare with only a few previously reported cases. The reported cases were seen in polyarteritis nodosa or Takayasu arteritis. We report the first case of periostitis associated with IgA vasculitis with demonstration of computed tomography (CT), magnetic resonance imaging (MRI) features, and serial changes of radiographs. PATIENT CONCERNS: A 74-year-old man visited an orthopedic outpatient clinic for pain in both lower legs and left ankle pain. He underwent a total ankle arthroplasty of the left ankle 3 years ago. His medical history disclosed IgA vasculitis/nephropathy caused by cephalosporin antibiotic class 5 months earlier. Plain radiography, MRI of the right lower leg, CT scan of the left ankle showed single lamellar to spiculated periosteal reactions at both tibia, fibula and left calcaneus. There was no evidence of bone or soft tissue mass lesions or cortical destruction. DIAGNOSIS: We concluded that this was a case of periosteal reactions associated with IgA vasculitis for the following reasons: (1) periosteal biopsy was negative for tumor. (2) there was no pulmonary lesion on chest radiography and CT, no history of trauma, inflammatory arthritis, metabolic disease, or genetic disease that could cause periostitis at multiple bones, (3) the initial MRI showed predominant signal changes around the tibial and fibular shafts, possibly explaining subsequent periosteal reactions, and (4) symptoms subsided with conservative treatment and follow-up radiographs showed remodeling of periosteal reactions. INTERVENTIONS: The patient took conservative management. OUTCOMES: His calf pain improved, and a radiograph 7 months later showed remodeling to the solid or single lamellar periosteal reaction along the both tibia and left fibula. CONCLUSION: Awareness of this uncommon manifestation would help differential diagnosis of periostitis and could help decrease the patient's anxiety. It should also be noted that periosteal reactions by benign entities could cause aggressive-looking periosteal reactions in post-operative regions.

Spectrum of Voriconazole-Induced Periostitis With Review of the Differential Diagnosis.

OBJECTIVE: Voriconazole is an antifungal medication used primarily for the treatment of Candida and Aspergillus infections. A fairly newly described side effect of long-term voriconazole use is periostitis. The purpose of this article is to describe the main differential consideration-hypertrophic osteoarthropathy-and other differential diagnoses, including venous stasis, thyroid acropachy, and hypervitaminosis A. CONCLUSION: With knowledge of imaging appearance, clinical manifestations, and outcomes, radiologists can make an accurate diagnosis of voriconazole-induced periostitis, and clinical teams can initiate appropriate management.
