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
Tumours or disorders affecting the breasts in pregnant or lactating women are usually similar to those occurring in non-pregnant women, but some lesions are unique
Mammary fibromatosis is a rare benign lesion of the breast with clinical and radiological manifestations mimicking breast cancer. We present a woman with fibromatosis

We present a case of a 56-year-old woman who had mammographic findings of coarse popcorn-like calcification in the right breast. In year 2000, the patient had benign lumps
External auditory canal and middle ear involvement is an uncommon initial presentation for early primary nasopharyngeal carcinoma. Previously reported cases were only associated with advanced skull base erosion or recurrence after radical treatment. We present a patient with
In dementia of the elderly, the majority of patients with onset around the eighth decade have typical Alzheimer’s disease; diagnostic workup is usually simple, and a plain computed tomography brain is sufficient to exclude pathology other than generalised brain atrophy.
Neuroscintigraphy for dementia includes brain perfusion single-photon emission computed tomography (SPECT) [hexamethylpropyleneamine oxime or ethyl cysteinate dimer] and fluorodeoxyglucose positron emission tomography (PET), which are the two most common
Dementia is an increasingly prevalent disease of the ageing population. Although Alzheimer’s disease is still the most common cause of dementia, there is emerging clinical interest in other, less common, causes of dementia that can affect patients at a younger
Perivascular epithelioid cell tumour is a relatively new entity with rising incidence. This is a rare mesenchymal neoplasm that can occur in various organs and is characterised by proliferation of perivascular cells and expression of myomelanocytic markers. Here, we present
Central nervous system tuberculosis usually presents as tuberculous meningitis, intracranial tuberculoma, tuberculous brain abscess, or tuberculous mass. Tuberculoma originates as a conglomerate of microgranulomata in an area of tuberculous cerebritis that joins to form a
Post-traumatic postoperative osteolysis is a rare cause of recrudescence of osteolysis in previously quiescent sclerotic pagetic bone. This condition can develop rapidly following trauma and operation, and mimic sinister causes like malignancy. Awareness of this rare disease entity
Patients with early local recurrence of nasopharyngeal carcinoma with close proximity to the nearby carotid artery can be offered long-term control by endoscopic nasopharyngectomy which allows complete microscopic clearance of the recurrent tumour without damaging the
Objective: To study the prevalence of non-calcified plaque causing significant coronary artery stenosis in patients with zero or low coronary artery calcium scores in a regional hospital in Hong Kong.
Objective: To determine the accuracy of specimen radiograph in predicting ductal carcinoma in situ resection margin status during radioguided occult lesion localisation.

Objectives: To determine the utility of the multiecho two-point Dixon technique in the semi-quantification of hepatic fat in patients with chronic liver disease and compare these results with the histopathology outcomes.
Mandibular metastasis in hepatocellular carcinoma is rarely seen. Since the first case reported in 1957,
only about 70 cases have been reported. To the best of our knowledge, only two cases presenting with acute
Venous thromboembolism and pulmonary embolism are potentially fatal complications that could occur after extracorporeal membrane oxygenation (ECMO). Prophylactic insertion of inferior vena cava filters prior
Multidetector (MD) cardiac computed tomography (CT) imaging has emerging use in the assessment of the anatomy and function of the heart. Apart from its established role in the evaluation of the coronary arteries,
Neurenteric cyst is a notably rare epithelium-lined cystic lesion found in the central nervous system. Malignant
transformation of the neurenteric cyst is infrequent, with only six cases reported in the English literature.
Schistosomiasis is the second most prevalent parasitic disease worldwide, which is rarely reported in developed countries like Hong Kong. We report a case of schistosomal appendicitis in a 79-year-old male presenting
