Diagnostic role of shear wave elastography for differentiating benign and malignant breast masses
Published in SA Journal of Radiology
Background Use of B-mode ultrasound (US) may not obviate the need for diagnosis by histopathology, which is an invasive technique and remains the gold standard. These limitations are being overcome with the advent of shear wave elastography (SWE). Objectives To assess the diagnostic role of SWE parameters and combined SWE and B-mode US in diagnosin...
Not always ‘squame’: The rare entity of follicular dendritic cell sarcoma of the tonsil presenting with cervical nodal m...
Published in SA Journal of Radiology
Although squamous cell carcinoma accounts for the overwhelming majority of head and neck malignant neoplasms, extranodal follicular dendritic cell sarcoma (FDCS) of the pharyngeal region can have a similar clinical presentation. The histopathological features of this rare entity have been described and emphasised in the literature. We present the c...
Hydatid disease of the interventricular septum: Echocardiographic and computed tomography findings
Published in SA Journal of Radiology
Hydatid disease (HD) is prevalent in South Africa, with cardiac HD being a rare but important manifestation to recognise and diagnose. An incidental finding on computed tomography (CT) of the chest in a patient with pulmonary HD prompted further multimodality imaging, which confirmed the presence of cardiac HD involving the interventricular septum....
Bilateral Hutch diverticula in an elderly male: Revelation of an unknown past
Published in SA Journal of Radiology
Hutch diverticulum is a congenital diverticulum of the urinary bladder, reported infrequently in children and rare amongst adults. We present a 60-year-old male patient with bilateral Hutch diverticula, detected incidentally during an abdominal ultrasound examination performed for blunt abdominal trauma. This rare case highlights an unusual inciden...
The Cinderellas of the scanner: Magnetic resonance imaging ‘pre-scan’ and ‘post-scan’ times: Their determinants and impa...
Published in SA Journal of Radiology
Background Increasing demand for magnetic resonance imaging (MRI) has contributed to extended patient waiting times worldwide. This is particularly true in resource-limited environments, prompting this institutional workflow analysis. Objective To determine the ‘pre-’ and ‘post-scan’ times for normal-hour MRI studies conducted at a tertiary-level, ...
Vigorous achalasia: Zebra amongst horses
Published in SA Journal of Radiology
Vigorous achalasia is an oesophageal disorder with clinical and radiological characteristics of classic achalasia and diffuse oesophageal spasm. It is a rarely reported variant. A 60-year-old gentleman presented with complaints of difficulty in swallowing, regurgitation and chest pain for the past 10 years. His symptoms persisted despite the use of...
Herniation of the uterus, ovaries and fallopian tubes into the canal of Nuck in a 4-month-old child: A rare entity
Published in SA Journal of Radiology
Partial or complete failure of obliteration of the processus vaginalis in the female results in the formation of a potential space known as the canal of Nuck, into which various organs and/or collections can herniate. A 4-month-old female presented with a left labial mass related to herniation of the uterus, ovaries and fallopian tubes through the ...
A pictorial review of the pathophysiology and classification of the magnetic resonance imaging patterns of perinatal ter...
Published in SA Journal of Radiology
This article provides a correlation of the pathophysiology and magnetic resonance imaging (MRI) patterns identified on imaging of children with hypoxic ischemic brain injury (HIBI). The purpose of this pictorial review is to empower the reading radiologist with a simplified classification of the patterns of cerebral injury matched to images of pati...
An audit of radiation doses received by paediatric patients undergoing computed tomography investigations at academic ho...
Published in SA Journal of Radiology
Background Diagnostic reference levels (DRLs) are a crucial element of auditing radiation doses in paediatric computed tomography (CT). Currently, there are no national paediatric CT DRLs in South Africa. Objectives The aim of this article was to establish local paediatric DRLs for CT examinations at two academic hospitals and to compare paediatric...
