Intractable hiccups can stem from brainstem lesions, not just psychogenic causes. Magnetic resonance imaging (MRI) is crucial for diagnosing these lesions, unlike computed tomography.

Area of Science:

Neurology
Neuroimaging
Infectious Diseases

Background:

Intractable hiccup is a debilitating condition often misdiagnosed.
Brainstem lesions are an underrecognized cause of persistent hiccups.

Observation:

Four patients with brainstem lesions presented with intractable hiccup and neurological signs.
Magnetic resonance imaging (MRI) identified brainstem infarction and central nervous system tuberculomas.
High-resolution enhanced computed tomography failed to detect some brainstem lesions.

Findings:

Central nervous system tuberculomas responded well to antituberculous chemotherapy, resolving hiccups.
Brainstem infarction was identified as a cause of intractable hiccup.
Hiccup may represent myoclonus of the 'inspiratory solitary nucleus' due to loss of inhibitory control.

Implications:

MRI is vital for diagnosing brainstem lesions causing intractable hiccup.
Early diagnosis and treatment of central nervous system tuberculomas can resolve hiccups.
Understanding the neuroanatomical network of hiccup formation aids in management.
