We herein report a 10-month-old female infant with a 4-month history of
diarrhea with electrolyte abnormalities and growth impairment. A 4-cm
right adrenal tumor was detected by computed tomography. No metastasis
or accumulation on I123-metaiodobenzylguanidine scintigraphy was
recognized in the tumor. A vasoactive intestinal peptide-secreting
neuroblastic tumor was suspected, and octreotide was started, but the
diarrhea persisted. Tumor extirpation was performed laparoscopically.
After tumor removal, the symptoms improved immediately, and her growth
caught up by nine months after surgery. A minimally invasive approach
for pediatric solid tumor is difficult, especially for neuroblastoma,
but may be beneficial for the patient's recovery.
