    Abstract The left hepatic vein (LHV) anomalous drainage into the coronary sinus (CS) is an extremely rare congenital vascular abnormality. It is usually asymptomatic, but it has surgical implications if the patient undergoes cardiac, vascular or hepatic procedures. We report a case of a 90-year-old man who had an isolated LHV anomalous drainage diagnosed on a computed tomography performed to evaluate fatigue. The diagnosis of LHV drainage into the CS during preoperative evaluation can avoid intraoperative complications and may determine the preferred surgical approach.

    Abstract Purpose: Our study aimed to evaluate the diagnostic performance of rectal magnetic resonance imaging (MRI) for local restaging in patients with non-metastatic locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (CRT) using surgical histopathology of total mesorectal excision as the reference standard.
    Methods: Ninety-five patients with LARC who underwent rectal MRI after CRT between January 2014 and December 2016 were included. Accuracy, sensitivity, specificity, positive, and negative predictive value for local staging regarding T-stage, N-stage, circumferential resection margin, and MRI tumor regression grade (ymriTRG) were calculated, and inter-test agreements were assessed.
    Results: 22/95 (23.2%) patients had radiological complete response (rCR), whereas 20/95 (21.1%) had pathological complete response (pCR). Among the patients with pCR, 11/20 (55%) had rCR. Fair agreement was demonstrated between ymriTRG and pathological TRG (ypTRG) (κ = 0.255). The sensitivity and specificity for detection of pCR were 61.1% (95% CI 35.7-82.7) and 89.6% (95% CI 80.6-95.4). For the detection of ypTRG grades 1 and 2, the corresponding values were 67.2% (95% CI 54.3-78.4) and 51.6 (95% CI 33.1-69.8). The accuracy of ymriTRG was 24.2% (95% CI 15.6-32.8). Inter-test agreement in TRG between MRI and pathology was overall fair (κ = 0.255) and slight (κ = 0.179), if TRG 1 + 2.
    Conclusion: Qualitative assessment on MRI for diagnosing pCR showed moderate sensitivity and high specificity, whereas the diagnosis of TRG had moderate sensitivity and low specificity with slight to fair inter-test agreement when compared with pathological specimens.

    Abstract Purpose: The present article provides an overview of the spectrum of abdominal presentations of fishbone (FB) ingestion and its complications.
    Methods: In image data from 9 patients, FB perforations were found in different levels of the gastrointestinal tract (GIT), including duodenal, jejunal, and sigmoid perforations; in 4 asymptomatic patients, FBs were observed in the mesentery, falciform ligament, and intestinal bowel.
    Results: The main imaging features of FB perforation were focal gastric or intestinal wall thickening, fat stranding, bowel obstruction, ascites, localized pneumoperitoneum, intra-abdominal abscess, liver abscess, and a linear hyperdense structure in the abdominal cavity in the GIT or within a parenchymal organ often surrounded by inflammatory changes. Free pneumoperitoneum was rare.
    Conclusion: Although in most cases, a FB does not cause any serious complications, an inflammatory process and complications may occur when it perforates the stomach or bowel loops. Radiologists need to be aware of the possibility of FB perforation, especially in high-risk patients, because it is not always considered in the differential diagnosis by referring physicians and can mimic other inflammatory conditions and tumoral lesions.
