Summary

Metastatic angiosarcoma to the brain is rare. Diagnosis of brain lesions preceded primary tumor identification in both cases, highlighting the need for early detection strategies.

Area of Science:

  • Neurology
  • Oncology
  • Pathology

Background:

  • Metastatic angiosarcoma to the brain is an exceptionally rare clinical presentation.
  • Angiosarcoma is a malignant tumor of endothelial cell origin, typically affecting soft tissues.

Observation:

  • Two cases of metastatic angiosarcoma involving the brain are presented.
  • Patients developed intracranial hemorrhage, with metastatic lesions diagnosed before the primary tumor in both instances.
  • Tumor characteristics included significant vascularity and sensitivity to radiation therapy, with recurrence noted in one patient.

Findings:

  • Ulex europaeus 1 lectin and factor VIII were crucial immunohistochemical markers for diagnosing angiosarcoma.
  • Radiation therapy demonstrated efficacy in managing brain metastases, though recurrence occurred.
  • Metastatic lesions were identified in the liver and femur following initial treatment.

Implications:

  • This case series underscores the diagnostic challenges and rarity of brain metastases from angiosarcoma.
  • Early recognition of intracranial hemorrhage as a potential symptom is vital.
  • Immunohistochemistry plays a critical role in differentiating angiosarcoma from other neoplasms.
