Immunoglobulin G4–related systemic disease (IgG4-RSD) is a newly recognised and emergent condition, which was initially thought to manifest only as autoimmune pancreatitis. As the knowledge about this disease
Undifferentiated nasopharyngeal carcinoma is particularly common in Southern China and is consistently associated with Epstein-Barr virus. In contrast, lymphoepithelioma-like carcinoma of the bile duct is a rare
We report a case of isolated extranodal Rosai-Dorfman disease occurring in iliac bone. Magnetic resonance imaging, computed tomography, and pathological features of Rosai-Dorfman disease are discussed.
Lipoblastoma is a rare benign adipocytic tumour that usually occurs in children younger than 3 years, with male predominance. Lipoblastoma usually presents as a slowly enlarging soft tissue mass in the extremities
Disseminated peritoneal hydatidosis is rare. Infrequently hydatid cysts can rupture into adjacent organs. We report a case of secondarily disseminated peritoneal hydatidosis with rupture into the gut presenting
Mild encephalitis / encephalopathy with a reversible splenial lesion is an uncommon condition that mainly affects young patients and children. Epilepsy and the use of antiepileptic medications are considered to be
Renal epithelioid angiomyolipoma is a rare variant of renal angiomyolipoma. The condition occurs in patients with or without tuberous sclerosis. Clinical behaviour of renal epithelioid angiomyolipoma varies widely,
Objectives: To determine the correlation between computed tomography (CT) scanning in evaluating the acute abdomen and the associated surgical outcome.
Methods: This was a retrospective observational study of 362 patients (198 females, 164 males) admitted
Objectives: To determine the effect of transarterial chemoembolisation (TACE) on liver function and procedure-related mortality in patients with unresectable hepatocellular carcinoma (HCC) and portal vein tumour thrombosis (PVTT).
Objective: To investigate the utility of the Appendicitis Computed Tomography (ACT) scoring system in the diagnosis of perforated appendicitis and prediction of surgical outcome.
Objectives: To review the clinical and pathological features of autoimmune pancreatitis (AIP) in a tertiary referral centre in Hong Kong, and to determine preoperative factors that facilitate diagnosis of AIP in order to
Hirayama disease is a type of cervical myelopathy affecting young men and causing wasting of the small muscles of the hand. The underlying pathophysiology is thought to be due to disproportionate growth of the vertebral column and the spinal canal resulting in a tight dural sac. The presentation of Hirayama disease is
Fistula-in-ano is a highly devastating disease due to its high morbidity. In order to achieve excellent surgical outcome, preoperative evaluations are essential. Magnetic resonance imaging (MRI) allows high spatial resolution images and is highly accurate in delineating the type and extent of a perianal fistula.
Extravasation of contrast medium is a complication of contrast-enhanced computed tomography studies. Clinical presentations include minimal swelling, erythema and, when the extravasated volume is large, ulceration, compartment syndrome, and skin necrosis. Here we present an 80-year-old woman with
Vertebrobasilar dolichoectasia is defined as elongation, dilatation, and tortuosity of the basilar and vertebral arteries. We describe two patients with vertebrobasilar dolichoectasia, one who presented with acute posterior circulation infarct and
Oesophageal intramural haematoma is an uncommon form of oesophageal injury. Oesophageal intramural haematoma can occur spontaneously without any preceding events. This report is of two patients who presented with haemoptysis and

Direct carotid cavernous sinus fistula is a common delayed complication of head trauma, particularly in patients with skull base fractures. When carotid cavernous sinus fistula occurs together with
Hepatocellular carcinoma is a common malignancy in this locality due to the high prevalence of hepatitis B carriers. Radiofrequency ablation is frequently used for treatment of hepatocellular carcinoma. Thermal injury
Objectives: To determine the magnetic resonance (MR) imaging features of localised giant cell tumour of the tendon sheath in fingers and to evaluate the preoperative diagnostic performance of MR imaging in assessment of the local tumour extent.

Objective: To compare the incidence of catheter-related infection in the bloodstream and non-infectious complication rate of Hickman catheter and peripherally inserted central venous catheter (PICC) in oncology patients.
Objective: To review the technical feasibility and effectiveness of N-butyl cyanoacrylate (NBCA; Histoacryl, B. Braun, Melsungen, Germany) embolisation to control acute arterial haemorrhage and embolisation of pseudoaneurysms in extracranial locations.
Objective: Carotid duplex ultrasound has revealed that radiotherapy is associated with stenosis of the extracranial carotid arteries in patients with nasopharyngeal carcinoma (NPC). The objective of the study was to
Objectives: To determine the influence of background parenchymal enhancement (BPE) in preoperative magnetic resonance imaging (MRI) breast assessment and its impact on
Objectives: To assess the sonographic visibility and feasibility of biopsy under ultrasound guidance of mammographically suspicious microcalcification-only lesions.
Objective: Male breast cancer (MBC) is a rare disease entity and few data are available for the Chinese population. This study aimed to report MBC data
Triple-negative breast cancer is a distinct clinical subtype characterised by tumours that do not express oestrogen receptor, progesterone receptor, or HER-2 oncogene. Patients with triple-negative breast cancer
