両側多発副腎嚢胞が自然消退したBeckwith-Wiedemann症候群の1例

A case of spontaneous resolution of bilateral adrenal cysts in Beckwith-Wiedemann syndrome

Beckwith-Wiedemann症候群（BWS）は，巨舌，腹壁欠損，過成長を三徴とする先天性奇形症候群である。BWS患者の5～10％に腹部腫瘍が合併することが知られ，副腎腫瘤の合併も報告されている^1）。今回我々は，BWSに合併した副腎嚢胞を経過観察し消退を確認できたまれな症例を経験したので，文献的考察を交えて報告する。

We report a case of Beckwith-Wiedemann syndrome（BWS）complicated by adrenal cysts. A neonatal female presented with hypoglycemia and was diagnosed with BWS. Prenatal and postnatal ultrasound suggested adrenal masses, and MRI confirmed bilateral adrenal cysts. As there were no malignant features, the patient was managed conservatively. The cysts resolved spontaneously during observation. Abdominal tumors occur in 5-10％ of BWS cases, and adrenal masses have been reported. However, documentation of spontaneous resolution during observation is exceedingly rare.
