Splenic Heterogeneity in Focused Assessment With Sonography for Trauma (FAST) Scan Led to the Diagnosis of Grade 2 Splenic Injury in a Pediatric Blunt Abdominal Trauma

Splenic injuries are one of the most common injuries following blunt abdominal trauma. It occurs in 32% of blunt abdominal trauma, with motor vehicle accidents being the most common cause. The patient may present with generalized abdominal pain or left upper quadrant pain associated with left shoulder pain. Hemodynamic instability is one of the most reliable signs of splenic injuries. A focused assessment with sonography for trauma (FAST) scan is the initial imaging used to assess for solid organ injury in the abdomen, followed by computed tomography (CT) scans. Evidence of free fluid in the abdomen in the FAST scan indicates a solid organ injury. However, the absence of the before-mentioned finding does not rule out the presence of solid organ injury. Hereby a case of a 13-year-old Saudi male with left-sided abdominal pain after falling from a motorbike. A set of the investigation was done with insignificant results. However, FAST revealed a heterogenous appearance in the spleen. Thus, the patient subsequently underwent abdominal CT scans. The patient was managed conservatively and then discharged against medical advice (DAMA). Previously documented cases have mentioned the presence of free fluid in the abdomen in FAST scan in a stable patient leading to undergoing a CT scan and further managing trauma victim patients, which was absent in the present case.
