Simulated acute appendicitis secondary to ventriculoperitoneal shunt

Area of Science:

• Neurosurgery
• Gastroenterology
• Surgical Complications

Background:

• Ventriculoperitoneal shunts are neurosurgical devices used to treat hydrocephalus.
• Abdominal complications can arise secondary to shunt insertion.
• Simulated appendicitis is a rare but significant presentation of shunt malfunction.

Observation:

• A patient presented with symptoms strongly suggestive of acute appendicitis.
• The clinical presentation was perplexing, initially obscuring the true cause.
• Diagnostic laparotomy was required to establish the diagnosis.

Findings:

• The acute appendicitis symptoms were found to be caused by a misplaced or malfunctioning ventriculoperitoneal shunt.
• This represents a novel abdominal complication associated with ventriculoperitoneal shunts.
• The shunt's presence and abdominal placement led to the simulated appendicitis.

Implications:

• This case expands the differential diagnosis for acute abdominal pain in patients with ventriculoperitoneal shunts.
• It underscores the importance of considering iatrogenic causes for abdominal symptoms.
• Awareness of this complication can improve diagnostic accuracy and patient outcomes.
