Posturally-evoked vomiting; Association with posterior fossa lesions
The Annals of Otology, Rhinology, and Laryngology
|January 1, 1977
Summary
Posturally-evoked vomiting (PEV) can indicate a serious central nervous system issue, not just benign vertigo. This symptom may precede other signs of posterior fossa mass lesions.
Area of Science:
- Neurology
- Neuroscience
- Otolaryngology
Background:
- Posturally-evoked vomiting (PEV) is a rare symptom.
- Distinguishing PEV from benign postural vertigo is crucial for diagnosis.
Observation:
- Two patients presented with PEV as a primary symptom.
- PEV occurred before other clear indicators of posterior fossa mass lesions.
Findings:
- PEV, when dissociated from vertigo, suggests a central lesion in the posterior fossa.
- Benign postural vertigo typically indicates peripheral vestibular disorders.
Implications:
- PEV can be an early warning sign of infratentorial mass lesions.
- Understanding the neuroanatomical basis of PEV is important for clinical practice.
