Primary medullary hemorrhage associated with hypertension

Area of Science:

• Neurology
• Vascular Neurology
• Neuroimaging

Background:

• Spontaneous primary medullary hemorrhage is an uncommon neurological event.
• Clinical presentation can mimic lateral medullary syndrome.
• Identifying underlying causes is crucial for patient management.

Purpose of the Study:

• To investigate the potential causes of spontaneous primary medullary hemorrhage.
• To analyze the clinical and radiological findings in a patient with this rare condition.
• To highlight the role of hypertension in primary medullary hemorrhage.

Main Methods:

• Case report of a 64-year-old male patient.
• Clinical assessment including neurological examination.
• Magnetic Resonance Imaging (MRI) including T2(*)-weighted gradient echo and contrast-enhanced sequences.
• Evaluation for common causes like anticoagulant use, vascular malformations, and pontine hemorrhage extension.

Main Results:

• The patient presented with sudden-onset vertigo and vomiting, consistent with lateral medullary syndrome.
• No anticoagulant therapy, vascular malformation, or pontine hemorrhage extension was identified.
• Evidence of multiple hypertensive changes was present, including retinopathy, left ventricular hypertrophy, cerebral microbleeds, and small-vessel changes on MRI.
• Prior MRI scans showed no vascular malformation.

Conclusions:

• Uncontrolled hypertension is a likely etiological factor in this case of primary medullary hemorrhage.
• Hypertensive changes and cerebral microbleeds may indicate a predisposition to spontaneous hemorrhage in the medulla.
• This case underscores the importance of managing hypertension to prevent catastrophic neurological events.
