Intracranial thrombosed anastomosing hemangioma: Case report

Area of Science:

• Neurology
• Pathology
• Vascular Biology

Background:

• Anastomosing hemangioma is a rare, benign vascular proliferation typically found in the genitourinary tract.
• Imaging features of anastomosing hemangiomas can mimic malignant tumors, posing diagnostic challenges.
• Differential diagnosis for intracranial lesions is broad, including vascular malformations and neoplasms.

Observation:

• A 33-year-old male presented with seizures and an intracranial lesion initially presumed to be a recurrent meningioma on imaging.
• Surgical resection was performed, and pathological examination revealed the lesion to be an anastomosing hemangioma.
• This represents the first reported case of a thrombosed anastomosing hemangioma in the intracranial, intradural location.

Findings:

• The intracranial lesion, initially suspected as meningioma, was pathologically confirmed as an anastomosing hemangioma.
• The case demonstrates a thrombosed anastomosing hemangioma presenting in a rare intracranial location.
• Histopathological analysis is crucial for differentiating anastomosing hemangioma from other intracranial neoplasms.

Implications:

• This case expands the known anatomical distribution of anastomosing hemangiomas.
• It underscores the need for a broad differential diagnosis in neuro-oncology, even for seemingly typical presentations.
• Accurate pathological diagnosis is essential for appropriate patient management and understanding of vascular lesions.
