Adrenal myelolipoma is a rare benign neoplasm composed of mature adipose and hematopoietic tissue. Most lesions are small, unilateral and asymptomatic, discovered incidentally at autopsy or on imaging studies performed for other reasons. We would like to present a case report of this rare tumour. Cross-sectional imaging is helpful in making a pre-operative diagnosis. The size of the lesion should be a criterion for surgical intervention.

The incidence of transuterine perforation and migration of intrauterine contraceptive devices (IUCDs) into the abdominal cavity has been estimated at less than 0.1%. It has been suggested that intraperitoneal IUCD have low morbidity and may be left in situ. We report the first case of closed loop small bowel obstruction due to migration of a “Saf-T-Coil” IUCD into the abdominal cavity, where it became embedded in the omentum and ultimately, 31 years after deployment, coiled both arms around a loop of ileum. This late complication underlines the dangers of intra-abdominal foreign bodies, even when chemically and biologically inert.

Introduction Minimally invasive parathyroidectomy has advantages over the traditional bilateral neck exploration for the surgical treatment of primary hyperparathyroidism. It requires accurate localisation of the parathyroid pathology prior to surgery. The best method of preoperative localisation in a district general hospital setting is not well understood. Methods All patients who underwent parathyroidectomy for primary hyperparathyroidism from 2008 to 2016 were identified from a prospectively maintained database. Operative findings were correlated with radiological and histological results. Sensitivity and specificity of ultrasound, sestamibi scintigraphy and the two together were calculated for diagnostic precision and compared. Results One hundred and eighty-four patients met the inclusion criteria, of whom 81.5% had a histological diagnosis of a parathyroid adenoma. Ultrasound had higher sensitivity than sestamibi scintigraphy. Used together, ultrasound and sestamibi scintigraphy performed better than either ultrasound or sestamibi scintigraphy alone (P< 0.001). Twenty-two of 184 cases had no lesion located by either ultrasound or sestamibi scintigraphy preoperatively. Where neither ultrasound nor sestamibi scintigraphy located the lesion, additional computed tomography led to the excision of parathyroid pathology in one in ten patients. Conclusion The combination of ultrasound and sestamibi scintigraphy provides the highest sensitivity of preoperative localisation. This approach led to a high success rate of minimally invasive parathyroidectomy. Where preoperative localisation is not achieved with ultrasound or sestamibi scintigraphy, computed tomography adds little additional benefit. In this setting other modalities of localisation such a selective venous sampling, intraoperative methylene blue or intraoperative parathyroid hormone levels could be considered.

A previously healthy 10-year-old boy presented to the emergency department with central abdominal pain, loose stool and vomiting. He was diagnosed with gastroenteritis, but was well enough to be discharged. The next day he reattended with ongoing diarrhoea and vomiting, with the pain now localised to the right iliac fossa (RIF). Acute appendicitis was suspected, and he was taken for laparoscopic appendicectomy. At surgery, a gangrenous appendix was found, with pus extending from the pelvis up to the liver. The appendix was excised and thorough peritoneal washout performed. Postoperatively, he received 48 hours of intravenous antibiotics and was discharged home. Unfortunately the boy presented again 11 days later with right lower quadrant pain and fever. Ultrasound revealed a collection in the RIF, and he returned to theatre for washout. His recovery was slow until the peritoneal pus sent for bacterial culture grew Salmonella enteritidis, identification of which facilitated appropriate antibiotic treatment.
