    Chronic encapsulated brain hematomas, often from angiomatous malformations, present as encapsulated lesions. Surgical removal is successful, highlighting their consideration in brain mass diagnoses.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Pathology

    Background:

    • Chronic encapsulated hematomas are rare intracranial lesions.
    • Angiomatous malformations can be an underlying cause.

    Observation:

    • Two cases presented: an intracerebral hematoma in a 43-year-old male and an intracerebellar hematoma in an 8-year-old boy.
    • CT scans showed encapsulated lesions; angiography revealed space-occupying and small vascular lesions.
    • Both hematomas were surgically excised.

    Findings:

    • Histological examination revealed a thick, fibrous capsule originating from an occult angiomatous malformation.
    • Hematomas contained old thromboses and areas of both old and recent hemorrhage.
    • Recent hemorrhages were attributed to ruptured vessels within the capsule.

    Implications:

    • Chronic hematoma should be considered in the differential diagnosis of encapsulated brain mass lesions.
    • Understanding the origin from angiomatous malformations is crucial for surgical planning.
    • This condition, though uncommon, requires recognition for appropriate patient management.
