[Spontaneous non-hypertensive cerebral hematomas].

V Lluch, J M Láinez, J Morera

    Archivos De Neurobiologia

    Summary

    Non-hypertensive brain hematomas (NHBH) often lack clear causes, with vascular malformations and tumors being common in younger patients. Early advanced imaging is crucial for diagnosis and guiding treatment in these critical cases.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Radiology

    Context:

    • Intraparenchymal brain hematomas (NHBH) represent a significant clinical challenge.
    • Distinguishing NHBH from hypertensive causes is vital for accurate diagnosis and management.
    • This study retrospectively analyzes the etiopathogenesis and treatment of 35 NHBH cases.

    Purpose:

    • To evaluate the causes and therapeutic strategies for non-hypertensive intraparenchymal brain hematomas.
    • To compare the characteristics of NHBH with hypertensive hematomas.
    • To identify key diagnostic and management recommendations for NHBH.

    Summary:

    • Of 35 NHBH cases, 48% had unknown etiology; common causes included vascular malformations (14%), brain tumors (14%), and anticoagulation therapy (9%).
    • NHBH predominantly occurred in the lobar regions (43%) and affected younger patients, with a 20% mortality rate.
    • Diagnosis relied on CT scans, with angiography confirming vascular malformations and ruling out other causes. Fifteen patients underwent surgery.

    Impact:

    • Highlights the importance of comprehensive etiological investigation for NHBH, especially in younger individuals.
    • Recommends early contrasted CT scans and angiography for atypical or non-hypertensive hematomas to identify underlying pathologies.
    • Suggests clinico-radiological follow-up and histological analysis for surgically treated cases with negative angiography.
