Summary
A 16-year-old male experienced severe constipation and abdominal pain due to superior mesenteric artery syndrome (SMAS). Treatment involved hydration, decompression, antibiotics, and nutritional support to manage this rare condition.
Area of Science:
- Gastroenterology
- Radiology
- Pulmonology
Background:
- Superior mesenteric artery syndrome (SMAS) is a rare gastrovascular disorder.
- It occurs due to extrinsic compression of the third portion of the duodenum by the superior mesenteric artery.
Observation:
- A 16-year-old male presented with constipation, abdominal pain, lethargy, and weakness.
- Imaging revealed a dilated esophagus, stomach, and duodenum, indicative of SMAS.
- Bilateral lung consolidation suggested aspiration pneumonia.
Findings:
- The patient was diagnosed with superior mesenteric artery syndrome (SMAS) complicated by aspiration pneumonia.
- Radiography showed gastric distension and transverse colon displacement.
- CT confirmed duodenal dilation and a narrow aortomesenteric angle.
Implications:
- Early diagnosis and multidisciplinary management are crucial for SMAS patients.
- Nutritional support and addressing comorbidities like aspiration pneumonia are vital for recovery.
- This case highlights the importance of considering SMAS in adolescents with obstructive symptoms.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
