Epidermal inclusion cyst is a common cutaneous condition. However, epidermal cyst deep in the breast parenchyma is rare. Diagnosis can be difficult if there is no suspicious clinical history. An onion-ring
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
