Eosinophilic cholangitis: US, CT, and cholangiography findings.

We report a case of eosinophilic cholangitis, with US, CT, and cholangiographic findings. The lesion showed marked wall thickening of cystic and common bile ducts on US and CT together with mild diffuse narrowing of the common duct on cholangiography.

Squamous cell carcinoma of the lung with simultaneous metastases to peritoneum and skeletal muscle

Skeletal muscle and peritoneum are rare sites of metastases from lung cancer. We report a case of squamous cell lung cancer with concurrent metastases to skeletal muscle and peritoneum. A 71‐year‐old man was diagnosed with squamous cell carcinoma of the right lower lobe with metastasis to the right hilar lymph node at clinical stage T3N1M0. Because of poor performance status and comorbidity, he only received radiation therapy. Positron emission tomography‐computed tomography for mid‐assessment of response showed two abnormal hypermetabolic lesions in the peritoneum of the left upper quadrant area and the left thigh muscle. We performed a needle‐approach biopsy in each lesion and found both of the lesions were metastases from lung cancer. The patient died after two months.

A case of hepatocellular carcinoma in the caudate lobe successfully treated by transcatheter arterial chemoembolization using drug-eluting beads

Hepatocellular carcinoma (HCC) in the caudate lobe remains one of the most intricate locations where various treatments tend to pose problems with regard to the optimal approach. Surgical resection has been regarded as the most effective treatment; however, isolated resection of the caudate lobe is strenuous and associated with a high rate of early recurrence. Percutaneous ablation might be technically difficult or impossible to perform due to the deep location of tumors and adjacent large vessels. Treatment with drug-eluting beads (DEB) can potentially enhance the therapeutic efficacy for patients with unresectable HCC by drawing on the slower, more consistent drug delivery process. We described a case of a 62-year-old man with HCC in the caudate lobe who was successfully treated by DEB.
