Insights
Molybdenum cofactor deficiency, a rare neurometabolic disorder, can manifest as pyloric stenosis. This case report suggests considering hypertrophic pyloric stenosis in infants with molybdenum cofactor deficiency.
Area of Science:
- Neurology
- Metabolic Disorders
- Pediatrics
Background:
- Molybdenum cofactor deficiency (MCD) is a rare, severe neurometabolic disorder.
- MCD presents neonatally with seizures, hypotonia, developmental delay, and feeding issues.
- Pyloric stenosis, a cause of infant vomiting, may be linked to neurological factors.
Abstract:
Molybdenum cofactor deficiency is a rare neurometabolic disease that is usually characterized by seizures, abnormal muscle tonus, developmental delay and poor nutrition, and is seen soon after birth. Pyloric stenosis causes serious vomiting in the first months of life. The presence of neurologic damage in molybdenum cofactor deficiency and possible abnormal innervations may cause pyloric stenosis; however, the pathogenesis is unclear. Pyloric stenosis with molybdenum cofactor deficiency has been described in two cases. Herein, we report the third case and suggest that hypertrophic pyloric stenosis should be kept in mind as a clinical manifestation of molybdenum cofactor deficiency.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
