A 54-year-old man presented with left-sided weakness and altered mental status. CT demonstrated a large acute right middle cerebral arterial infarct with midline shift and uncal herniation. He underwent right decompressive hemicraniectomy with storage of bone flap in the periumbilical subcutaneous pocket. The patient was referred for whole-body bone scan for evaluation of osseous metastases secondary to newly suspected renal cell carcinoma. It showed increased radiotracer uptake in the right lower quadrant of the abdomen corresponding to the site of implanted bone flap, confirming its viability. The autologous bone flap was subsequently successfully reimplanted in the cranium.
