Caecal faecolith: ultrasonic--radiologic diagnosis.

The entity of caecal faecoliths is not well known to most radiologists. It presents as a hard tender palpable mass in the right iliac fossa. It usually occurs in older women with chronic constipation. On ultrasound it appears as an intracaecal, highly echogenic, shadowing mass. Plain radiographs may show lamellated calcifications. Barium enema shows a well defined intracaecal mass. Using a combination of ultrasound and plain films or barium enema, a preoperative diagnosis should be possible.

Digital subtraction angiography (DSA). Work load and financial implications for a neuroradiology department.

A four year study has been undertaken into the effects on the workload and cost implications of the introduction of digital subtraction angiography (DSA) in a large United Kingdom teaching hospital. The increase in workload has been entirely due to the ability to perform intravenous angiography. DSA is cheaper than conventional angiography if more than 210 cases are undertaken each year. This difference is accounted for by the reduced use of X-ray film. However, intravenous angiography is more expensive because of the use of large volumes of nonionic medium.

Post-traumatic cysts and cyst-like lesions of bone.

We describe two patients with cyst-like lesions of bone that developed at sites of healed or healing fractures. One case showed histological features of a unicameral bone cyst, which, to the best of our knowledge, is a previously unreported finding in a post-traumatic cyst. It is suggested that there are two principal clinical and radiological types of post-traumatic cyst, of which each of our cases represents an example: (1) asymptomatic transient cortical lesions, found only in children, and (2) more central expanding lesions, found in a wider age group and associated with pain, swelling, and pathological fractures.

Orbital intraconal haematic cysts in young people: computed tomography and magnetic resonance imaging.

Eight cases of focal non-traumatic haemorrhage into the intraconal retrobulbar space in children or young adults have been examined by computed tomography. The lesion is seen as a smoothly rounded, localized mass, which does not extend to fill the intraconal space. Magnetic resonance imaging in two cases did not reveal the expected high signal on T1-weighted images, but in most patients the combination of clinical and radiological features is sufficiently indicative of the diagnosis to allow conservative management.
