This appearance on a plain abdominal film of a 30 year-old woman was an incidental finding. The calcification seen in the left side of the pelvis is the typical appearance of an ovarian dermoid cyst. Dermoid cyst is a loose term given to cysts are various sites lined by squamous epithelium. Ovarian dermoids account for about 20% of ovarian tumours. The vast majority (99%) are benign and may contain mature tissues such as bone, teeth, cartilage, hair and thyroid tissue. |

This 70 year-old man presented with a one month history of jaundice, pale stools and dark urine. He had been generally unwell with right upper quadrant pain and weight loss for approximately three
months prior to admission. A liver ultrasound showed multiple hepatic metastases. An ERCP showed obstruction within the porta hepatitis suggestive of portal lymphadenopathy. A stent could not be inserted
endoscopically. This procedure is a percutaneous transhepatic cholangiogram showing grossly dilated intra-hepatic ducts. A guide wire was inserted percutaneously and stenting achieved by a combined procedure

This 79 year-old lady presented with a one week history of colicky abdominal pain, distension and vomiting. She was dehydrated. Abdominal examination confirmed distension and showed a
midline mass and high pitched bowel sounds. This supine film was taken showing a coffee bean shaped gas-filled viscus arising from the right iliac fossa. The radiological appearance is that of caecal volvulus. After
resuscitation the patient proceeded to a laparotomy. The caecum was decompressed. The caecum was viable, no resection was required and caecopexy with a tube caecostomy was performed. She made an uncomplicated recovery from
her surgery.

This 30 year-old lady presented with left loin pain. She had no other urinary symptoms of note. Abdominal examination was unremarkable. Urinalysis was normal. As part of her out-patient
investigation this intravenous urogram was performed. It shows dilatation of the left renal pelvi-calyceal system with delay in the excretion of contrast. The ureter was normal. The appearances are those of a
pelvi-ureteric junction obstruction. A renal isotope scan showed good renal function and she proceeded to an Anderson-Hymes pyeloplasty to improve drainage of the kidney. She made an uncomplicated recovery from her surgery.
