UNASSIGNED: The present study reports the case of a 68-year-old male @entity1 who presented to Tokyo Rosai Hospital for the treatment of @entity5881 . A high density was observed in liver segment S2, while a @entity5 , 30 mm in size, exhibiting a low density was observed in the delayed phase upon contrast-enhanced computed tomography (CT), which was performed prior to admission. The @entity5 appeared slightly poorly defined upon abdominal ultrasound and was observed as a 30 mm low-echoic nodule that was internally heterogeneous. A 5-mm thick contrast enhancement effect was observed in the @entity5 border in the vascular phase on Sonazoid contrast-enhanced ultrasonography, while a defect in the entire @entity5 was observed in the post-vascular phase. @entity1282 had commenced three months prior to presentation and a weight loss of ~3 kg was observed. Therefore, the @entity1 was admitted to Tokyo Rosai Hospital due to the presence of a @entity99 , and to undergo a close inspection of the cause of the @entity5 . Upon close inspection, it was determined that the weight loss and aphagia were caused by progressive @entity10296 . A contrast-enhanced CT was performed on post-admission day 29 as a follow-up regarding the @entity99 . As a result, although no change in the @entity5 size was observed, the contrast enhancement in the @entity5 borderline had disappeared. Necrosis of the @entity5 was considered. However, as viable persistence of the @entity5 could not be excluded, a hepatic left lobe excision was performed. The @entity1 was diagnosed with @entity157 ( @entity157 ) based on the morphology of the cellular @entity39 . In addition, occlusion due to @entity715 was observed within the blood vessels passing inside the fibrous capsule. It was hypothesized that the formation of a thick fibrous capsule and occlusion due to @entity715 in the feeding vessel were possibly involved as the cause of complete spontaneous @entity39 . Written informed consent was obtained from the @entity1 .
