Computerized texture analysis predicts histological invasiveness within lung adenocarcinoma manifesting as pure ground-glass nodules.

CONCLUSION: In patients with pGGN, computerized texture analysis has the potential to differentiate histological invasiveness; maximum 3D diameter, surface volume ratio, and zone entropy in particular are independent differentiators of IACs from AISs and MIAs.

A 72-year-old man with a history of T1cN0M0 prostate adenocarcinoma and rising prostate-specific antigen underwent a fluciclovine PET/CT scan that showed high uptake in several para-aortic nodes, suspicious for prostate cancer. A right upper lobe single pulmonary nodule (SPN), demonstrated only mild uptake, which raised the suspicion for a lung primary. Subsequent FDG PET/CT showed high uptake in the SPN, revealing poorly differentiated adenocarcinoma at biopsy, but with no abnormal uptake in the para-aortic nodes. This case highlights the complementary potential of fluciclovine and FDG PET in patients with a history of pr...

We report the case of a male patient with cutaneous metastasis of prostate adenocarcinoma located in the cervical and upper thoracic area. The patient also had a history of pulmonary tuberculosis. A CT scan revealed the presence of bone metastasis, pleural effusion, and infiltration of the soft tissues of the neck. The histopathological study confirmed the presence of cutaneous metastasis of primary prostate neoplasia. We present this case due to its unusualness and its importance in the differential diagnosis of this pathology. PMID: 31800950 [PubMed - in process]

We reported a case of 18 years-old female patient admitted to Mansoura oncology center with severe abdominal pain. Physical examination revealed a distended abdomen with hepatomegaly with no abdominal mass. Computed tomographic (CT) scan of the abdomen revealed markedly enlarged liver with multiple innumerable variable sized hyper-echoic non-enhanced focal lesions. The patient underwent an ultrasound- guided biopsy of the liver that showed metastatic yolk sac tumor. Colonoscopy confirmed a large polypoidal ulcerating mass that was 15 cm from anal verge. Biopsy from the mass revealed conventional colonic adenocarcinoma merg...

Conclusions: The finding of advanced colonic neoplasia in follow-up colonoscopy after an acute episode of CT-proven diverticulitis is equivalent to, or less than, that of the population colorectal cancer screening program. Routine colonoscopy is not necessary unless there are other concerning symptoms/CT findings.

Authors: Zhuo SQ, Ma HL, -Z Liu L, Ruan GY, Xie CB, Huang WJ, Yang GJ, Li ZP, Zeng SH Abstract OBJECTIVE: At lower energy levels, virtual monochromatic imaging by dual-energy computed tomography improves lesion attenuation but produces greater image noise with the conventional monoenergetic reconstruction algorithm (Mono). Recently, a second-generation algorithm (Mono+) was introduced to overcome this limitation. We compared the quality of images obtained with these algorithms and investigated the optimal energy selection for pancreatic ductal adenocarcinomas (PDACs). PATIENTS AND METHODS: Image data from 54 PD...

AbstractThe Japanese guideline for gastroenteropancreatic neuroendocrine tumor treatment recommends everolimus or sunitinib as first-line treatment for unresectable pancreatic neuroendocrine tumors (PNETs). Streptozocin (STZ) is recommended as an alternative. We encountered a patient with PNET who had multiple liver metastases and who showed a remarkable response to third-line STZ. The patient was a 50-year-old man with a pancreatic head tumor 32  mm in diameter. We planned to perform subtotal stomach-preserving pancreaticoduodenectomy, but abandoned resecting the pancreas during the surgery upon discovering a small l...
