| Abstract | 「要旨」肝細胞癌の塞栓術後経過観察中に, 眼窩腫瘍が生じその診断に99mTc-PMTシンチグラフィが有用であった一例を報告する. 症例は70歳男性で, 胃癌の既往がある. 2か月前より右眼部痛, 頭痛, 右視力障害を自覚し, 近医にて右眼窩腫瘍を指摘され, 精査・加療目的に当院を紹介された. 眼部X線CT・MRIで右眼窩外側壁に, 著明な骨破壊を伴った腫瘍が認められた. AFPの著明な上昇により, 肝細胞癌の眼窩転移が疑われ, 施行した99mTc-PMTシンチグラフィで, 腫瘍に一致した強い集積が認められ, 肝細胞癌の眼窩転移と診断することができた. 99mTc-PMTシンチグラフィは肝癌患者の遠隔転移の診断に非常に有用であることが示された. また, 18F-FDG PETでは, 腫瘍内の分布において内側に特に代謝の亢進した部を認め, 後のMRIで腫瘍内側からの浸潤増殖が見られたことは, 非常に興味深い事実と思われた. |

| Abstract | [Summary] We reported a case in which 99mTc-PMT scintigraphy was useful in diagnosing orbital metastasis of HCC. The case involved a 70 y.o. male, who had undergone nine transcatheter arterial embolizations over two years because of HCC and who had a past history of gastric cancer. The patient had complained of headache and visual disturbance for two months. Cranial CT and MRI studies showed a large homogeneous mass with remarkable bone destruction in the right lateral orbital wall. Because AFP was elevated, orbital metastasis of HCC was suspected, and 99mTc-PMT scanning was performed. On the planar and SPECT images, very high uptake was found in the right orbital tumor. The FDG-PET study showed remarkable hypermetabolism in the medial portion of tumor and follow-up MRI revealed that the tumor had expanded and invaded to the medial side of the orbit. 99mTc-PMT scanning was critical in diagnosing this case of orbital metastasis, and FDG-PET imaging was useful in determining the most active portion of the tumor. |
