Insights
This case report details chronic encapsulated intracerebral hematoma (CEIH), a rare brain lesion. Histology confirms diagnosis, distinguishing it from similar pathologies like tumors.
Area of Science:
- Neurology
- Pathology
- Radiology
Background:
- Chronic encapsulated intracerebral hematoma (CEIH) is a rare brain lesion with unclear etiology.
- Distinguishing CEIH from chronic cerebral hematoma, abscess, and tumors requires specific clinical and imaging criteria.
- Literature review identified 39 reported cases of CEIH.
Observation:
- The defining characteristic of CEIH is a capsule separating the hematoma from the brain parenchyma.
- In this case, an adjacent arteriovenous malformation was noted outside the CEIH.
- Diagnosis was definitively established through histological examination.
Findings:
- CEIH presents a diagnostic challenge due to its rarity and poorly understood formation.
- Histological analysis is crucial for confirming the presence of a capsule, differentiating CEIH.
- The presence of adjacent vascular malformations may be a relevant associated finding.
Implications:
- Accurate differentiation of CEIH is vital for appropriate patient management and treatment planning.
- Further research into the capsule formation mechanism is needed.
- Understanding CEIH aids in refining differential diagnoses for intra-axial brain lesions.
Abstract:
The purpose of this case report is to describe chronic encapsulated intracerebral hematoma (CEIH), a rare and not fully understood brain lesion. The differentiation from chronic cerebral hematoma, cerebral abscess, and intra-axial tumor is based on clinical and imaging criteria. The diagnosis is confirmed by histological analysis. In the English medical literature, we found 39 patients reported with this lesion. The key feature is the formation of a capsule between a hematoma and cerebral parenchyma. The reasons for this formation are not known. In our patient, an arteriovenous malformation was located outside but adjacent to the CEIH.
