“…In addition to conventional endoscopic approach, EUS provides the ability to stage the tumor by evaluation for depth of tumor, local spread and lymph node involvement with possibility of tissue sampling [10]. With the advent of imaging modalities: CT, MRI and PET of chest, abdomen, and pelvis; patients can be evaluated for local as well as distant spread [10,11].…”

Primary rectal Squamous Cell Carcinoma (SCC) is a distinct and extremely rare form of colorectal malignancy and submucosal rectal SCC is rarer. The etiology and pathogenesis of rectal SCC is poorly understood. Given the rare occurrence of this type of malignancy, there are a number of diagnostic and therapeutic dilemmas. We are reporting a case of a 56-year-old female, who presented with abdominal pain and found to have rectal mass which was subsequently biopsied under endoscopic ultrasound guidance. Histopathology showed primary submucosal squamous cell carcinoma. She was treated with radiotherapy and systemic chemotherapy. Now she is undergoing regular malignancy surveillance.

“…Some pitfalls of transrectal US include the inability to use it when patients have bulky, obstructive tumors; small field of view, which limits evaluation of deep perirectal tissue and lymph node stations; inability to evaluate the mesorectal fascia; and operator dependency (9,11,33). The American College of Radiology appropriateness criteria currently recommend endorectal US over MR imaging for use in evaluation of small or superficial tumors, and MR imaging over endorectal US for larger lesions (34).…”

“…Although at this time, FDG PET/CT is not recommended for first-line imaging in staging of all rectal cancers, it can be used in certain situations, for troubleshooting, and most importantly, for treatment planning. PET/CT is currently recommended by the American College of Radiology for staging of large rectal cancers because results of studies have shown that use of this modality may accurately change the staging or influence treatment planning for this subset of patients (34,39). Results of several metaanalyses have shown PET/CT to be superior to CT for use in detection of hepatic metastases (40,41).…”

“…Nevertheless, routine liver MRI is generally not performed for the staging of extra-hepatic oncology diseases. For example, the American College of Radiology Appropriateness Criteria for pre-treatment staging of colorectal cancer recommended CT of the chest, abdomen and pelvis for the initial evaluation of disease [45] . In the majority of the cases, staging liver MRI is required to evaluate doubtful FLLs.…”

Since its clinical introduction, several studies in literature have investigated gadolinium ethoxybenzhyl diethylenetriaminepentaacetic acid or gadoxetic acid (Gd-EOB-DTPA) properties. Following contrast injection, it provides dynamic vascular phases (arterial, portal and equilibrium phases) and hepatobiliary phase, the latter due to its uptake by functional hepatocytes. The main advantages of Gd-EOB-DTPA of focal liver lesion detection and characterization are discussed in this paper. Namely, we focus on the possibility of distinguishing focal nodular hyperplasia (FNH) from hepatic adenoma (HA), the identification of early hepatocellular carcinoma (HCC) and the pre-operative assessment of metastasis in liver parenchyma. Regarding the differentiation between FNH and HA, adenoma typically appears hypointense in hepatobiliary phase, whereas FNH is isointense or hyperintense to the surrounding hepatic parenchyma. As for the identification of early HCCs, many papers recently published in literature have emphasized the contribution of hepatobiliary phase in the characterization of nodules without a typical hallmark of HCC. Atypical nodules (no hypervascularizaton observed on arterial phase and/or no hypovascular appearance on portal phase) with low signal intensity in the hepatobiliary phase, have a high probability of malignancy. Finally, regarding the evaluation of focal hepatic metastases, magnetic resonance pre-operative assessment using gadoxetic acid allows for more accurate diagnosis.© 2014 Baishideng Publishing Group Inc.

Three main topics are summarized: the role of gadoxetic acid in the evaluation of solid benign hepatic lesions, represented by hepatocellular adenoma and focal nodular hyperplasia; the diagnostic capability of hepatobiliary phase of gadoxetic acid-enhanced liver magnetic resonance imaging in the early identification of small hepatocellular carcinoma; the high diagnostic accuracy powered by gadoxetic enhanced-liver MRI in the detection of hepatic metastasis.
