Amyloidosis is a rare disorder where abnormal protein aggregates are deposited in tissues forming amyloid fibrils, leading to progressive organ failure. Although any organ can be affected, cardiac involvement is the main cause of morbidity and mortality associated with amyloidosis as diagnosis is often delayed due to the indolent nature of the disease in some forms. An early diagnosis of disease and knowledge of the type/subtype of cardiac amyloidosis (CA) are essential for appropriate management and better outcome.

Methods: This is a retrospective review of swab-positive patients with COVID-19 who were admitted to four different hospitals in Singapore between 22 January and 9 March 2020.
A bacterial mass in the urinary tract is a very rare entity. We report the first case of a bacterial ball within the urinary tract of a patient with diabetic cystopathy on long term urinary indwelling catheter. She presented with fever and gross haematuria.

Lung cancer is the leading cause of cancer-related death around the world, being the top cause of cancer-related deaths among men and the second most common cause of cancer-related deaths among women in Singapore. Currently, no screening programme for lung cancer exists in Singapore. Since there is mounting evidence indicating a different epidemiology of lung cancer in Asian countries, including Singapore, compared to the rest of the world, a unique and adaptive approach must be taken for a screening programme to be successful at reducing mortality while maintaining cost-effectiveness and a favourable risk-benefit ratio.

- This study evaluated the effectiveness of coronary computed tomography angiography (CCTA) at Changi General Hospital in Singapore over two years.
- It analyzed data from 679 patients, finding a negative predictive value of 85.7% and a positive predictive value of 86.2%, indicating the reliability of CCTA results.
- The study concluded that negative CCTA results were associated with a one-year period without major adverse cardiovascular events (MACE), aligning with existing clinical data.
A 77-year-old man presented with acute-onset severe chest pain radiating to the back and elevated blood pressure. Multiphasic computed tomography of the aorta revealed an intimal tear in the descending thoracic aorta which extended both retrograde to the aortic root and antegrade to the infra-renal abdominal aorta. The initial impression, that the images showed a Stanford type B aortic dissection, was because the portion of the false lumen that extended beyond the aortic arch remained unopacified even on delayed phases, making it challenging to assess the extent of the dissection flap.

Accurate diagnosis of this condition is critical in the management of this potentially fatal condition. This paper reviews the MDCT imaging features of Kommerell aneurysms and its mimics and demonstrates how to make an accurate diagnosis through a series of four cases.

We explain the underlying pathophysiology that results in these clinical syndromes so that the patient subset who will benefit from treatment can be identified.
Conclusion: The abdominal vascular compression syndromes discussed here are uncommon and are potentially easily missed on a cursory review of radiologic examinations, particularly in a nonspecific and vague clinical setting.
In Asian cuisine, fish is often prepared whole with the bones. Accidental fish bone (FB) ingestion is not an infrequently encountered condition in the emergency department. An impacted FB in the alimentary canal can lead to potentially life-threatening complications.
View Article and Find Full Text PDFThe advent of multidetector computed tomography (MDCT) has largely supplanted plain radiography as the recommended primary imaging modality for the evaluation of acute spinal injuries. Although MDCT is highly sensitive and specific for bony injuries, errors in diagnosis can still occur. Knowledge of the possible imaging pitfalls on MDCT, leading to either misdiagnosis of fractures or missed fractures, is vital in ensuring an accurate diagnosis.
