Clinical characteristics and outcomes of patients with hepaticangiomyolipoma

“Angiomyolipoma (AML) is a solid mesenchymal tumor, mainly described in the
kidney, and belongs to the group of perivascular epithelioid cell tumors
(PEComas). Hepatic localization of AML, described for the first time in 1976, is
rare, since only around 600 cases were reported after an exhaustive search of the
literature up to the year 2017. Hepatic AML (HAML) poses a veritable diagnostic
challenge in radiological terms, especially when fat content is low, because this type of
tumor may appear as a hypervascular tumor associated with a washout phase that
mimics other, more common hypervascular hepatic tumors, such as hepatocellular
carcinoma”

ABI staging for acute bowel ischemia: Imaging findings

“Acute bowel ischemia (ABI) can be life threatening with high mortality rate. The radiologist plays a central role in the initial diagnosis and preventing progression to irreversible intestinal ischemic injury or bowel necrosis. The most single imaging findings described in the literature are either non-specific or only present in the late stages of ABI, urging the use of a constellation of features to reach a more confident diagnosis”

Preoperative portal vein embolization for major liver resection

Rassam F, et al. Functional and volumetric assessment of liver segments after portal
vein embolization: Differences in hypertrophy response. Surgery. 2019 Apr;165(4):686-695.

Full-text for Emory users.

RESULTS: A total of 90 patients underwent portal vein embolization of the right liver. After 3 weeks, there was a significant increase in both volumetric and functional share of the future remnant liver (both P < .01). The increase in functional share exceeded the increase in volumetric share (P < .01). The median functional contribution of segment 4 after portal vein embolization was 41.5% (31.7%-48.7%) of the nonembolized lobe. Preoperative chemotherapy was not a significant predictor of the increase in function or volume. Compared with benign lesions, malignant diseases were significant negative predictors of the functional response.
