Silent subperiosteal iliac hematoma with bone radiolucency in adolescent male athletes.

ABSTRACT:

Background

Subperiosteal hematoma of the iliac bone is reported as a rare disorder that specifically occurs in young patients after obvious trauma. This report presents seven cases of male adolescent athletes with subperiosteal iliac hematoma without blunt trauma that was identified as an incidental radiolucent lesion on the iliac bone mimicking neoplasm. The purpose of this report is to describe clinical features and radiological findings of silent subperiosteal hematoma of the iliac bone.

Subjects and methods

We retrospectively reviewed the clinical data and radiological appearance of 7 patients who presented with subperiosteal hematoma of iliac bone.

Results

All seven patients had no obvious trauma and no serious symptoms. All patients were middle school or high school male students who regularly participated in vigorous sports activity; five soccer players, one baseball catcher, and one basketball player. The X-ray showed radiolucent lesion on the iliac bone. Lens-shaped mass without involvement of psoas muscle with ghost native cortex sign and overlying periosteal calcification on CT scan was characteristic radiological finding on subperiosteal iliac hematoma.

Conclusion

Subperiosteal iliac hematomas can be caused by vigorous sports activity in adolescence. This condition is not always associated with serious symptom. It can be identified as a radiolucent lesion mimicking a neoplasm.

Project description:Sport concussions can be difficult to diagnose and if missed, they can expose athletes to greater injury risk and long-lasting neurological disabilities. Discovery of objective biomarkers to aid concussion diagnosis is critical to protecting athlete brain health. To this end, we performed targeted proteomics on plasma obtained from adolescent athletes suffering a sports concussion. A total of 11 concussed male athletes were enrolled at our academic Sport Medicine Concussion Clinic, as well as 24 sex-, age- and activity-matched healthy control subjects. Clinical evaluation was performed and blood was drawn within 72 h of injury. Proximity extension assays were performed for 1,472 plasma proteins; a total of six proteins were considered significantly different between cohorts (P < 0.01; five proteins decreased and one protein increased). Receiver operating characteristic curves on the six individual protein biomarkers identified had areas-under-the-curves (AUCs) for concussion diagnosis ≥0.78; antioxidant 1 copper chaperone (ATOX1; AUC 0.81, P = 0.003), secreted protein acidic and rich in cysteine (SPARC; AUC 0.81, P = 0.004), cluster of differentiation 34 (CD34; AUC 0.79, P = 0.006), polyglutamine binding protein 1 (PQBP1; AUC 0.78, P = 0.008), insulin-like growth factor-binding protein-like 1 (IGFBPL1; AUC 0.78, P = 0.008) and cytosolic 5'-nucleotidase 3A (NT5C3A; AUC 0.78, P = 0.009). Combining three of the protein biomarkers (ATOX1, SPARC and NT5C3A), produced an AUC of 0.98 for concussion diagnoses (P < 0.001; 95% CI: 0.95, 1.00). Despite a paucity of studies on these three identified proteins, the available evidence points to their roles in modulating tissue inflammation and regulating integrity of the cerebral microvasculature. Taken together, our exploratory data suggest that three or less novel proteins, which are amenable to a point-of-care immunoassay, may be future candidate biomarkers for screening adolescent sport concussion. Validation with protein assays is required in larger cohorts.
