CBCTAP had sufficient image quality to detect almost all small HCC lesions compared to conventional CTAP and could depict approximately 89% of HCC nodules, including eight suboptimal lesions.

Iodized oil accumulation and retention in the hypovascular portion of early-stage HCC was frequently observed after ultraselective TACE, mainly in the hypovascular portion with decreased portal blood.

A solid pseudopapillary neoplasm (SPN) is an uncommon pancreatic tumour that usually occurs in young women. Tumours outside the pancreas (e.g. in the ovary, retroperitoneum or omentum) are rare. We report a case of an SPN arising from the greater omentum in a 78-year-old male who presented with a month-long history of abdominal pain and a palpable abdominal mass. Laboratory data showed inflammation and anaemia. CT and magnetic resonance imaging revealed a well-defined encapsulated mass measuring 18 cm in the upper right abdomen. The tumour was completely removed via surgery, and pathologic examination confirmed a diagnosis of an SPN in the greater omentum.

Calcifying fibrous tumours (CFTs) are rare benign lesions that usually affect the soft tissues, the mesentery and the peritoneum. Gastric CFT is particularly rare. Here, we report a CFT found incidentally in a 31-year-old male. The mass was well circumscribed and showed partial calcification on the CT scan, with dark signal intensity seen on T2 weighted MRI. To the best of our knowledge, there is very limited published information concerning imaging findings of CFTs. We discuss the CT scan and MRI findings of this patient, which can be considered typical for gastric CFT, and present a review of the limited literature available.

There have been few reports of pulmonary arteriovenous malformations complicated by hemoptysis. Herein, we present our experience and provided a review of the literature. A man in his 80s came to our hospital with a chief complaint of hemoptysis, and a simple computed tomography showed a consolidation in the right lower lobe of the lung. He was treated for bacterial pneumonia, and his symptoms and a consolidation resolved, but similar episodes continued afterwards. About 18 months after the initial disease onset, the patient had hemoptysis and came to our hospital again. He was diagnosed with pulmonary arteriovenous malformation due to the presence of a lumpy, mass-like dilatation in the peripheral arteries. With the suspicion that the hemoptysis was caused by pulmonary arteriovenous malformations, the patient underwent coil embolization, and his symptoms gradually resolved. Computed tomography also showed improvement in shadowing. The hidden arteriovenous malformation was buried by a dense pulmonary field shadow; thus, it was diagnosed after a long time. This case highlights that pulmonary arteriovenous malformations should be considered in differentiating cases presenting with hemoptysis.
