Superior mesenteric artery syndrome (Wilkie's syndrome) complicating recovery from posterior fossa surgery in a child--a rare phenomenon.

INTRODUCTION: Superior mesenteric artery or Wilkie's syndrome is defined as compression of the third part of duodenum by superior mesenteric artery. It has not been previously reported in children after neurosurgical procedures. CLINICAL HISTORY: We present the case of a child who had persistent vomiting after surgery for posterior fossa astrocytoma complicated by low pressure hydrocephalus.
CONCLUSION: Despite eventual hydrocephalus control, vomiting persisted, and she was diagnosed with superior mesenteric artery syndrome, this being confirmed radiologically and settled with appropriate nutritional management.
