ICD-10: G46.4

Cerebellar stroke syndrome, classified under ICD-10 code G46.4, refers to a group of neurological symptoms resulting from a stroke affecting the cerebellum, the part of the brain responsible for coordination, balance, and fine motor control. Understanding the clinical description and details associated with this condition is crucial for accurate diagnosis, treatment, and coding.

Clinical Description

Definition

Cerebellar stroke syndrome occurs when there is an interruption of blood flow to the cerebellum, leading to ischemia or infarction of the cerebellar tissue. This can result from various causes, including embolism, thrombosis, or hemorrhage.

Symptoms

The clinical presentation of cerebellar stroke syndrome can vary, but common symptoms include:

• Ataxia: A lack of voluntary coordination of muscle movements, leading to unsteady gait and difficulty with balance.
• Dysmetria: Inability to control the distance, power, and speed of a movement, often observed during finger-to-nose testing.
• Nystagmus: Involuntary eye movements that can affect vision and balance.
• Dizziness and vertigo: Patients may experience a sensation of spinning or loss of balance.
• Speech disturbances: Dysarthria, or slurred speech, may occur due to impaired coordination of the muscles used in speech.
• Headaches: Some patients report headaches, particularly if the stroke is due to hemorrhage.

Etiology

Cerebellar strokes can be caused by:

• Ischemic strokes: Resulting from a blockage in the blood vessels supplying the cerebellum, often due to atherosclerosis or embolism.
• Hemorrhagic strokes: Caused by bleeding into the cerebellum, which can occur due to hypertension or vascular malformations.

Diagnosis

Diagnosis typically involves:

• Clinical evaluation: A thorough neurological examination to assess coordination, balance, and other cerebellar functions.
