Hiatal hernia with ulceration at the level of the diaphragm is a well-recognized and not uncommon condition. These ulcers may be simple gastric ulcers in patients who coincidentally have a hiatal hernia, or they may be related to trauma of the stomach against the diaphragm. They are not always readily detected on barium study. The clinical and radiological features in 3 recent cases are described, together with a brief review of the literature.
Myelographic changes after spinal operation are often difficult to interpret especially with regard to the differentiation between arachnoiditis and recurrent disc prolapse. The radiological appearances using iophendylate (Myodil) and the distinguishing features are discussed and illustrated.
Three patients who developed obstructive jaundice after mastectomy for carcinoma of the breast are presented. Prognosis is invariably poor as widespread metastases are usually present at the time of presentation. The pathogenesis, investigations and clinical significance are discussed.
The computed axial tomographic (CAT) findings in 22 children with intracranial neoplasms are presented. CAT offers a rapid, non-invasive method of assessing the locality and extent of these tumours, as well as the presence of calcification and hydrocephalus. CAT is of value in the follow-up treatment, but an absolute histological diagnosis is not always possible.
Caecal volvulus is usually associated with a twisted caecum, seen to occupy the umbilical area or left hypochondrium on radiography. Caecal bascule refers to the form of volvulus in which the distended caecum is situated within the pelvis. The caecal bascule type of obstruction is uncommon, and clinical and radiological appearances may be confusing. Two cases are presented and the incidence, pathogenesis and radiological features are discussed.
