Key result
Left femoral head replacement successfully treated a rare case of femoral epithelioid hemangioendothelioma, with no signs of recurrence observed at the 18-month follow-up.
Why the study?
Epithelioid hemangioendothelioma is an uncommon low-grade aggressive vascular tumor that rarely occurs in bone.
Case Report (n=1)
MRI and PET/CT are useful imaging modalities for the detection and definitive diagnosis of rare bone tumors like femoral epithelioid hemangioendothelioma.
PET/CT may aid rare bone EHE detection; leaves open prospective validation before routine diagnostic use.
BACKGROUND: Epithelioid hemangioendothelioma (EHE) is an uncommon low-grade aggressive vascular tumor. It can occur in almost all locations, but is rarely encountered in bone. CASE SUMMARY: F-deoxyglucose-positron emission tomography/computed tomography (PET/CT) imaging showed bone destruction in the left ischium, acetabulum, and left femoral head neck, accompanied by increased radioactive uptake; the maximum standard uptake value was 4.2. Histopathologic examination revealed spindle-shaped mesenchymal tissue hyperplasia with scattered epithelioid cells. The patient underwent left femoral head replacement surgery. No signs of recurrence were observed as of the 18-mo follow-up. CONCLUSION: The definitive diagnosis of femoral EHE can be established aided by the MRI and PET/CT findings.

Zhao et al. (2021) conducted a case report in Femoral epithelioid hemangioendothelioma (n=1). Left femoral head replacement was evaluated on Tumor recurrence. Left femoral head replacement successfully treated a rare case of femoral epithelioid hemangioendothelioma, with no signs of recurrence observed at the 18-month follow-up.
