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
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
