Partial pontine hematomas

C S Kase, G O Maulsby, J P Mohr

    Neurology
    |June 1, 1980
    PubMed
    Summary

    Small pontine and midbrain hematomas in hypertensive men presented with unusual neurological signs. These cases highlight atypical presentations of brainstem hemorrhage, differing from typical massive pontine bleeds.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Radiology

    Background:

    • Hypertension is a significant risk factor for intracranial hemorrhage.
    • Brainstem hemorrhages, particularly in the pons and midbrain, can lead to diverse clinical manifestations.
    • Computerized tomography (CT) is crucial for diagnosing and characterizing intracranial lesions.

    Observation:

    • Two hypertensive male patients presented with neurological deficits.
    • CT scans revealed small, predominantly unilateral hematomas in the pons and midbrain.
    • Clinical signs included ocular bobbing, complex ophthalmoplegia, Cheyne-Stokes respiration, and pyramidal tract signs.

    Findings:

    • The observed clinical features were atypical for massive pontine hemorrhage.
    • Key symptoms like coma, pinpoint pupils, and hyperthermia were notably absent.
    • The findings suggest that small, unilateral brainstem hematomas can present with a distinct neurological profile.

    Implications:

    • These cases expand the spectrum of clinical presentations for hypertensive brainstem hemorrhages.
    • Recognizing these atypical signs is vital for accurate diagnosis and timely management.
    • Further research may elucidate the specific mechanisms underlying these varied neurological deficits.
