History in Brief
• 68 Y Male hepatitis B and C negative
• Prior partial hepatectomy for a 4cm HCC (path:
well differentiated HCC, no vascular invasion).
• On Sorafenib (400mg BID)
• Triphasic CT showed numerous hypervascular
nodules with washout with the dominant burden
in Couinaud segment VI, VII
• Pleural metastasis with chronic right pleural
effusion seen on CT.
Arterial phase of a triphasic CT, demonstrating multiple hypervascular foci in
segment VI and VII that washed out on the portal venous and delayed phase (not
shown), consistent with HCC

Axial and coronal images of
the chest (A and B),
demonstrate a 2.5cm x
2.5cm x 5cm pleural based,
hypervascular nodule on
the right, consistent with
pleural metastatic disease
Laboratory Data
• AFP –Pre hepatectomy: 57, post-hepatectomy
28. At presentation:1137
• LFT: Total Bilirubin 0.8mg/dL, AST 37 U/L, ALT
38 U/L, Albumin 3.7g/dL, INR 1.2
• Creatinine 1.3mg/dL, Platelet count 78,000/µL

Early and delayed DSA imaging (A and B) of the thoracic aorta
demonstrates arterial supply of pleural mets supplied by the
intercostal arteries

Catheterization of the right 6th intercostal artery (A) and further selection
and placement of a 1.9Fr microcatheter in the distal portion of the 6th
intercostal artery (B), redemonstrates the hypervascular pleural met.
Pleural met treated with 31.3mg of Doxrubicin and 0.625mL of
Lipiodol (A). Prophylactic topical Ice was placed to prevent
cutaneous complications of non-target chemoembolization.
Unenhanced CBCT (B) demonstrates lipiodol staining in pleural met

Supply to pleural mets by 5th intercostal artery, treated in a
similar superselective fashion.
MIP images reconstructed from a contrast enhanced CBCT
obtained for radioembolization planning demonstrates
multifocal HCC.
Clinical Course
• Patient returned for Y90 administration on
Day 10.
• Erythema noted along the right posterior
chest without ulceration.
• Asymptomatic, no treatment for chest wall.
• Uneventful administration of Y90.
• Skin erythema resolved, without
consequences.
Discussion
• Lung is the most commonly affected organ of
extrahepatic metastases from HCC
• 1 year survival is approximately 30% after
diagnosis of pulmonary mets1
• Prognostic factors that predict survival after
diagnosis of pulmonary mets include
oligometastasis, absence of pleural effusion and
treatment of pulmonary metastases1
Discussion
• For intra- or extra-hepatic tumors supplied by extrahepatic arteries (intercostal arteries or internal mammary
arteries), cutaneous complications can occur when
therapeutic agents are delivered due to the inadvertent
deposition in the terminal cutaneous branches.
• Topical ice can be used to vasoconstrict cutaneous
vasculature and prevent non-target deposition2.
