Introduction: Historically, Pylorospasm is defined as a condition in which the infant's pyloric canal has some functional obstruction to organic matter, compared to hypertrophic pyloric stenosis, a well-known cause of after-feeding and repetitive vomiting in infancy. It is 61 years since the first use of oral Atropine for treating HPS, especially in those children with anesthesia or surgery who have restrictions. Afterward, in limited trials, IV Atropine was introduced for its more effective and less complicated nature.

Case presentation: We have reported a case of a premature male infant born by surrogacy and fed from a milk bank, whose acute after-meal intermittent vomiting led to a Pylorospasm diagnosis. He was successfully treated non-surgically by Intravenous (IV.) Atropine and gained weight.

Conclusion: In cases of suspension to HPS without sonographic evidence, Pylorospasm should be considered. In these conditions, Atropine can be a suitable and less complicated therapeutic alternative.
