Endovascular treatment of post-traumatic carotid-cavernous fistulae using latex detachable balloons : original articleSource: SA Journal of Radiology 9, pp 4 –15 (2005)More Less
<I>Objective.</I> To determine the efficiency of latex detachable balloons in the treatment of post-traumatic carotid-cavernous fistulae (CCF). <br><I>Methods.</I>Management and outcome were reviewed for 34 consecutive patients with post-traumatic CCF personally treated by one of the authors (PS) using latex detachable balloons during the 4-year period 1996 - 2000. <br><I>Results.</I> Endovascular embolisation of 34 CCFs was attempted in 33 patients. In 1 patient where the fistula was a result of rupture of an intracavernous aneurysm, the fistula thrombosed spontaneously before embolisation was attempted. In the 33 treated patients, the fistula was occluded in 30 cases (91%). Patency of the internal carotid artery was preserved in 16 cases (53%). <br><I>Conclusion.</I> A high percentage (91%) of direct CCFs were successfully occluded with latex detachable balloons. There were no permanent neurological complications in any of the patients treated.

Pathology affecting the suprasellar cistern is varied in paediatric neuroradiology practice. Although MRI is the imaging modality of choice for lesions of the suprasellar cistern, abnormalities can be detected on CT with knowledge of the normal anatomy and a sound approach to the possible pathological entities. We present our approach to pathology affecting the suprasellar cistern and highlight this using various cases seen at our institution in the recent past.
Hypertensive encephalopathy with CT confirmation in four children with acute renal disease : case reportSource: SA Journal of Radiology 9, pp 20 –22 (2005)More Less
Hypertensive encephalopathy (HE) is a clinical syndrome that occurs infrequently in children and is often underdiagnosed. We review four patients with HE and describe their clinical presentation and radiological findings on computed tomography (CT). Our cases demonstrate typical features on CT and correlate clinically with the syndrome of HE. Prompt recognition of the syndrome aids in earlier diagnosis and treatment, and hence proves beneficial to the patient.

LÃ¶ffler's syndrome was initially described as a disorder characterised by transient pulmonary infiltrates accompanied by peripheral blood eosinophilia in asymptomatic or mildly ill patients. Abnormal chest radiographic findings are said to occur in 95% of patients but there are no descriptions of CT findings. There are many causes of this syndrome, but in developing countries the most common presentation remains secondary to the migratory larvae of common intestinal helminths. We present the clinical and radiological features of a boy with clearly defined LÃ¶ffler's syndrome due to larval migration.

Lhermitte-Duclos disease (LDD) is a rare cerebellar lesion of uncertain origin. It is linked to an autosomal- dominant phakomatosis known as Cowden's disease in 40% of patients. The MRI features of LDD are almost unique and can be considered diagnostic. We report on a patient who presented with the typical MRI features of the above disease, and discuss the imaging features, pathology and genetics.
