Key result

Surgical excision of an intramuscular cavernous hemangioma improves pain without early recurrence at two weeks.

Why the study?

Intramuscular hemangiomas are rare benign vascular tumors frequently misdiagnosed due to deep location and vague presentation mimicking common orthopedic pathology.

Population

One 17-year-old male high school athlete with chronic anteromedial knee pain

Design

Case report

Follow-up

Two-week follow-up

Discussion

Implication

Short-term success in one athlete; leaves open whether excision improves outcomes for intramuscular cavernous hemangiomas.

Key Points

This report aims to highlight an often-misdiagnosed cause of chronic knee pain in adolescents.
Case study of a 17-year-old male high school athlete with anterior knee pain and swelling.
Imaging initially misinterpreted a deep lesion as a ganglion cyst.
Surgical excision performed followed by pathology confirmation of intramuscular hemangioma.
Post-surgery, the patient reported reduced pain and improved functionality.
No signs of recurrence at two-week follow-up.

Population

A 17-year-old male high school athlete with chronic anteromedial knee pain who underwent surgical excision of an intramuscular cavernous hemangioma and was followed for 2 weeks.

Intervention

Surgical excision (marginal excision) of the mass

Outcome

Pain improvement and recurrence at 2-week follow-up

Intramuscular hemangioma should be considered in adolescents with chronic periarticular pain or deep soft-tissue lesions, and surgical excision can be diagnostic and potentially curative.

Limitations

Patient was lost to follow-up beyond the two-week postoperative visit
Return-to-sport status was not assessed
Preoperative MRI was performed without intravenous contrast, limiting characterization of vascular lesions

Murthy et al. (2026) conducted a case report in Intramuscular cavernous hemangioma (n=1). Surgical excision was evaluated on Pain improvement and recurrence. Surgical excision of an intramuscular cavernous hemangioma in a 17-year-old athlete resulted in improved pain with no signs of early recurrence at two-week follow-up.
