Plexiform neurofibroma is a typical sign of neurofibromatosis type 1, although the condition is not diagnostic. These large lesions are associated with neurological deficits, affect cosmesis, and have a predisposition for
Central neurocytoma is an uncommon neuronal tumour that usually originates from the lateral ventricle or septum pellucidum. We present a rare case of central neurocytoma arising from the fourth ventricle and
Heterotopic pancreas is the presence of pancreatic tissue outside the normal location lacking ductal or vascular continuity with the main gland. There are case series describing the computed tomographic appearance
Objective: To audit requests for computed tomographic pulmonary angiograms, usage of pre-test pulmonary embolism probability scores, and D-dimer measurements in patients with suspected pulmonary embolism in aregional hospital in Hong Kong.
Crohn's disease is a chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract and may result in both intra- and extra-enteric complications. Evaluation of Crohn's disease and its complications has always be
Lymphangiomatosis is a systemic disorder that can affect any organ system that contains lymphatics, including bones and soft tissues, resulting in a wide range of clinical and radiological manifestations. This report highlights
Mesenteric fibromatosis is a fibroblastic proliferation of the mesentery and is often called an intra-abdominal desmoid tumour. It is a rare condition with the potential to cause significant morbidity and death due to its
Inflammatory myofibroblastic tumour is a rare benign neoplasm that has clinical presentations which may mimic malignancy. Most occur in childhood or early adulthood involving the lungs or orbits, but may occur at
Lipoblastomatous tumours are rare neoplasms derived from embryonic white adipose tissues. We report on two children with different types of lipoblastomatous tumours at rare sites. The first had a localised lipoblastoma within the peritoneal cavity, successfully
The clinical presentation of Parsonage-Turner syndrome often entails acute-onset shoulder pain, which may be confused with other entities such as rotator cuff tear, acute calcific tendonitis, adhesive capsulitis, cervical spondylosis, peripheral compressive
We describe magnetic resonance imaging in the preoperative evaluation of children with popliteal pterygium syndrome to identify the position of the popliteal artery and peroneal nerve. A nine-year-old boy, with known popliteal pterygium syndrome, had a problem
Epstein-Barr virus infection commonly affects adolescents and young adults. We present such an infection in a 72-year-old woman, who presented with weight loss for investigation. 18F-fluorodeoxyglucose positron emission tomography-computed tomography demonstrated
Objective: To determine whether the peri-tumoural choline/N-acetyl-aspartate ratio can be used to differentiate solitary primary intra-axial brain tumour and metatasis.
Methods: In this retrospective study, 18 treatment-naïve adults presenting with a
Objectives: To investigate among junior clinicians: (1) their level of knowledge and awareness of radiation dose of commonly performed radiological investigations and the associated risks of radiation exposure, and (2) their practice for obtaining informed

Objectives: Waiting time for radiotherapy is an important quality indicator for oncology services, and particularly so in the radical treatment for head and neck cancers where timing impacts treatment outcome. Reducing the waiting time for treatment is therefore
One of the areas where nuclear medicine has proved effective has been in the imaging of somatostatin receptor expressing tumours. These can be overexpressed in a number of tumours, but are most commonly seen in a family of
Percutaneous preoperative localisation of breast tumours using a hook-wire needle is a standard radiological practice. The use of a hook-wire in preoperative localisation of pulmonary
We report on a woman who presented with a history of lower limb weakness and numbness for a few months. Based on cross-sectional imaging, at first she was provisionally diagnosed to have an aggressive tumour around the spinal column.
We describe a case of lower limb deep vein thrombus in a patient with an inferior vena caval congenital anomaly, treated by insertion of two inferior vena caval filters.
Global hypoxic-ischaemic injuries to the brain are devastating and result in high mortality and morbidity in both children and adults. We report three cases from different causes of hypoxic-ischaemic injury to the brain in these age-groups.
Herein, we report a very rare case of a patient suffering from the simultaneous occurrence of an unusually gigantic posterior fossa varix (measuring 35 mm x 45 mm) and a tentorial dural arteriovenous fistula in the absence of intracranial
Myositis ossificans, also known as heterotrophic ossification, is characterised pathologically by the presence of lamellar bone at sites where bone normally does not exist. Its aetiology is unknown but is known to occur following
We report a rare instance of complete resolution of pulmonary metastatic lesions after gross total resection of a clear cell meningioma. This case showed that clear cell meningioma could metastasise to the lungs and that complete
