case_images: Image panel - Contrast-enhanced computed tomography identifies a mass in the right retrobulbar space on axial and coronal slices (left upper images, a and b). Single photon emission computed tomography/computed tomography and planar indium-111 octreotide demonstrates a solitary metastatic deposit (right upper and bottom row images, c-e)

case_images: On this admission, contrast CT of the orbits demonstrated an enhancing 1.6-cm lesion in the right retrobulbar space [Figure 1a and b]. Indium-111 (In-111) octreotide planar and single photon emission CT/CT imaging [Figure 1c-e] at 24 h demonstrated a solitary metastasis in the right retro-orbital soft tissues.
case_images: Follow-up single photon emission computed tomography/computed tomography imaging with indium-111-labeled octreotide demonstrates progression of metastatic disease, with two octreotide avid metastatic tumor deposits in the (contralateral) right kidney, which developed 2 years subsequently. An octreotide avid pulmonary metastasis is noted in the left lung

case_images: The patient remained well on 3-monthly surveillance; however, follow-up octreotide imaging 2 years later demonstrated the development of metastatic disease with avid right renal and pulmonary lesions [Figure 2], at which time systemic treatment with octreotide was commenced.
