After an otolaryngologic examination, the patients were investigated to determine the extent of the disease. These included full blood count, a search for hepatosplenomegaly, bone marrow examination, plain radiography and computerised tomography (CT) of the paranasal sinuses. Examination of the nose including the nasopharynx and biopsy of the nasal tumours under general anaesthesia were perform...

Three patients presented with sudden visual impairment followed by agitated delirium one to three days later. Examination revealed marked agitation, dementia, and loss of vision. Computerised axial tomography demonstrated temporo-occipital infarctions. All recovered from the agitated state in four days to two months, but their visual impairment and dementia persisted one to four years later.

• Renal angiomyolipomas (AMLs) are usually easy to diagnose with imaging alone. They have unique characteristics on ultrasonography, computerised tomography and magnetic resonance imaging that usually allow AMLs to be differentiated from other renal masses. • If this is not possible on imaging criteria then biopsy can be performed and AMLs have unique immunohistochemical staining that allows th...

6 As part of the diagnosis of liver disease, a Computerised Tomography (CT) scan is taken of the patient, which the clinician then uses for assistance in determining the presence and extent of the disease. This thesis presents the background, methodology, results and future work of a project that employs automated methods to segment liver tissue. The clinical motivation behind this work is the ...
