Establishing a quality assurance baseline for radiological protection of patients undergoing diagnostic radiology : original articleSource: SA Journal of Radiology 15, pp 70 –79 (2011)More Less
Background. The wide use of ionising radiation in medical care has resulted in the largest man-made cause of radiation exposure. In recent years, diagnostic departments in Kenya have adapted the high-speed film / screen combination without well-established quality control, objective image quality criteria, and assessment of patient dose. The safety of patients in terms of justification and the as-low-as-reasonably-achievable (ALARA) principle is inadequate without quality assurance measures.
Aim. This study assessed the level of film rejects, device performance, image quality and patient dose in 4 representative hospitals using high-speed film/screen combination.
Results. The X-ray equipment quality control tests performance range was 67% to 90%, and 63% of the radiographs were of good diagnostic value. The measured prevalent chest examination entrance surface dose (ESD) showed levels above the international diagnostic reference levels (DRLs), while lumbar spine and pelvis examination was the largest source of radiation exposure to patients.
Conclusion. The optimisation of patient protection can be achieved with optimally performing X-ray equipment, the application of good radiographic technique, and continuous assessment of radiographic image quality.

Pseudomyxoma peritonei (PMP) is a rare complication of mucinous tumours of appendiceal or ovarian origin that results in peritoneal and omental implants. Clinical morbidity and mortality arise from the fact that copious amounts of extracellular and peritoneal mucin result in distortion and loss of function of visceral organs. Therapeutic paracentesis is not possible because of the nature of the mucin. Currently, new techniques are being used to attempt to debulk the mucin volume; none, however, has lead to superior outcome.
Multiple skeletal lesions and pleural effusion owing to Histoplasma capsulatum infection in an immunocompetent patient from a nonendemic region : case reportSource: SA Journal of Radiology 15, pp 82 –84 (2011)More Less
We describe a rare case of multiple skeletal lesions and a pleural effusion owing to Histoplasma capsulatum infection in a 16-year-old immunocompetent girl residing in a non-endemic region. Of note is that she had a lesion within a thoracic vertebra. Following an extensive literature search, we found that vertebral involvement by H. capsulatum had not been previously described. Pleural effusion and skeletal lesions are both rare manifestations of H. capsulatum infection.

Arrythmogenic right ventricular dysplasia / cardiomyopathy (ARVD) is a familial cardiomyopathy characterised clinically by right ventricular (RV) dysfunction as well as ventricular tachycardia and histopathologically by fibro-fatty replacement of the myocardium. Left ventricular (LV) involvement can occur and appears to correlate with increased disease severity. Owing to the complexity of the disease, Task Force Criteria for diagnosis of ARVD were drawn up in 1994 and revised in 2010. Cardiovascular magnetic resonance (CMR) findings are now included in the list of major and minor criteria and currently play an important role in establishing the diagnosis of ARVD (see Table I). CMR is extremely valuable for delineation of right ventricular (RV) anatomy and function as well as for characterising the composition of the RV wall, especially regarding the presence of fatty and / or fibrous tissue.

A 34-year-old woman presented with a history of a previous laparoscopic cholecystectomy, followed within a few days by a formal laparotomy for a suspected bile duct injury. Approximately one week after the laparotomy, she developed a sinus on the anterior abdominal wall that was draining bile. She was then referred to our institution for further management. The earlier surgery was done at another hospital, and these details were not clear.

Vascular abnormalities associated with neurofibromatosis type 1 (NF1) are well described. Spinal arterio-venous fistula (AVF) is a rare finding in NF1 and may present with neurological symptoms that require treatment. Management of spinal AVFs can be endovascular or surgical. We present a patient with known NF1 and neurological symptoms due to a spinal AVF demonstrated by imaging, who required a combination of endovascular and surgical management.
Recurrent primary fallopian tube carcinoma presenting with an appendiceal metastasis : pictorial interludeSource: SA Journal of Radiology 15, pp 94 –95 (2011)More Less
A 61-year-old woman presented with a moderately differentiated serous papillary adenocarcinoma of the left fallopian tube in 2004. The tumour infiltrated the tube to the external surface. The uterus, cervix, right fallopian tube and ovaries were free of tumour, but peritoneal washings revealed the presence of metastatic tumour. The patient underwent chemotherapy but relapsed in 2009.

Please refer to page 63 of the June 2011 issue of the SAJR (http://www. sajr.org.za/index.php/sajr/article/view/579/443) for the presentation details. We congratulate Dr Himal Gajjar (Schnetler, Corbett and Partners, Cape Town) for a precise and detailed diagnosis, for which he receives an award of R1 000 from the RSSA. Dr Misser elaborates below on the condition and its imaging.
