A case of haemoperitoneum arising from an omental haematoma is described. Histology suggests that this resulted from an omental torsion. The omentum, however, was not torted at the time of laparotomy. Furthermore, there was a history of similar episodes of pain over the previous eighteen months. This suggests that spontaneous derotation of an omental torsion may occur, and may be an unusual cause of recurrent abdominal pain.

Background and aims Papillary thyroid microcarcinoma is defined as papillary thyroid cancer with a diameter of ≤1 cm. Despite its prevalence, there is wide variation in practice in the investigation and management of patients with papillary thyroid microcarcinoma throughout the UK and internationally. The primary aim of this paper is to describe the experience of investigation and management in a Scottish health board over the past 10 years. Methods and results Retrospective analysis of thyroidectomy and hemithyroidectomy resection samples from March 2009 to March 2020. 532 specimens were reviewed and 20 patients with PTMC were identified. 12 patients had an incidental finding of PTMC. Median U score- 3, Median Thy score- 2.5 for dominant or radiologically suspicious nodules. 8 specimens demonstrated aggressive histopathological features. 1 patient with positive nodal disease in the neck and 0 patients with positive nodal disease in the thorax on CT Neck and Chest. Conclusion Here we report the first UK Cohort describing the radiological investigation and management of papillary thyroid microcarcinoma. The results of our study are in accordance with a recent meta-analysis which found 4% nodal disease and 0.025% distant metastasis at time of presentation in patients with PTMC.
