Summary
This case report details a rare instance of intracranial hemorrhage from a synovial sarcoma metastasis. Early biopsy of suspicious soft-tissue masses over 5 cm is recommended for timely diagnosis and treatment.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Soft-tissue sarcomas are rare adult malignancies, often presenting as painless masses.
- Diagnosis can be delayed by atypical presentations or misdiagnosis, such as a synovial sarcoma mistaken for a Baker's cyst.
Observation:
- A 74-year-old female presented with intracranial hemorrhage due to a previously undiagnosed synovial sarcoma metastasis.
- The primary tumor, located in the popliteal vein, was initially misdiagnosed as a Baker's cyst and complicated by recurrent thrombosis due to sarcoma compression.
Findings:
- The patient underwent resection of the brain metastasis, biopsy of the popliteal tumor confirming synovial sarcoma, and above-knee amputation.
- The patient ultimately succumbed to pulmonary and further brain metastases 11 months post-diagnosis.
Implications:
- This case underscores the critical need for biopsy of soft-tissue lesions exceeding 5 cm or exhibiting growth, even when initially appearing benign.
- Intracranial hemorrhage can be a rare presenting symptom of advanced synovial sarcoma, necessitating comprehensive diagnostic evaluation.
