Cardiac haemangiomas are rare cardiac tumours that are usually asymptomatic and detected incidentally while imaging the heart with echocardiogram. cardiovascular magnetic resonance (CMR) is a non-ionising imaging modality that allows the diagnosis of cardiac haemangiomas prior to surgery. We report a 36-year old male patient who was referred to the adult cardiology Clinic at the Royal Hospital, Muscat, Oman, in 2006 with a history of a left ventricle mass detected on echocardiogram. further assessment of the mass by CMR revealed that the mass within the left ventricle apical septum contained features that were consistent with a cardiac haemangioma. due to the surgical risk of ventricular septal defect and the stability of the mass, the patient was managed conservatively and upon followup the patient’s condition remained stable.

Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss disease, is a rare vasculitis that affects small- to medium-sized vessels and has a propensity to involve the heart. Patients with cardiac involvement have a poor prognosis and usually require immunosuppressive treatment along with corticosteroids. Cardiovascular magnetic resonance (CMR) is a non-invasive diagnostic tool for detecting cardiac involvement and guiding the management plan. We report a 39-year-old male patient with a known history of bronchial asthma who was referred to the chest clinic at a tertiary hospital in 2019 for further assessment of persistent lung parenchymal changes on chest computed tomography. Given the clinical context of the patient and the radiological findings, EGPA was suspected and confirmed with a lung biopsy. CMR was performed for further assessment, which confirmed cardiac involvement. The patient was started on prednisolone and azathioprine and showed significant radiological and clinical improvement.

Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing mesenchymal neoplasm of the dermis and subcutaneous tissues that has a low- to intermediate-grade malignancy. DFSP commonly involves the trunk and extremities, and very rarely the breast skin, mimicking a primary breast neoplasm with few reported cases in the literature. we report a 35-year old female patient who was referred to the royal hospital, Muscat, Oman in 2017, with a two-year history of a slow growing left breast lump. assessment of the breasts with mammography revealed a lobulated lesion in the left-upper-inner quadrant with neither microcalcification nor architectural distortion, mimicking a benign lesion. however, on ultrasound, the lesion had suspicious features with increased vascularity and hence, it was categorised as breast imaging reporting and data system (BIRAD) IV. the patient underwent left breast wide local excision and the histopathological diagnosis was dermatofibrosarcoma protuberans.

Medical imaging, including chest radiography and computed tomography, plays a major role in the diagnosis and follow-up of patients with COVID-19 associated pneumonia. This review aims to summarise current information on this topic based on the existing literature. A search of the Google Scholar (Google LLC, Mountain View, California, USA) and MEDLINE® (National Library of Medicine, Bethesda, Maryland, USA) databases was conducted for articles published until April 2020. A total of 30 articles involving 4,002 patients were identified. The most frequently reported imaging findings were bilateral ground glass and consolidative pulmonary opacities with a predominant lower lobe and peripheral subpleural distribution.

A dual left anterior descending (LAD) artery is a rare congenital anomaly which is classified into different types based on the origin, course and termination of the short and long LAD arteries. To date, 10 variants of dual LAD artery anomalies have been described. We report a 44-year-old woman who was referred to the Department of Radiology, Royal Hospital, Muscat, Oman, in 2017. Coronary computed tomography angiography revealed a dual LAD artery anomaly in which the short and long LAD arteries shared a common ostium with the right coronary artery from the right coronary sinus. To the best of the authors’ knowledge, this type of variant has not been previously reported in the literature.

Amyloidosis is a disorder characterised by the extracellular deposition of amyloid, a fibrillary protein, in various organs such as the lungs. Pulmonary nodular amyloidosis can mimic other lung conditions that present with pulmonary nodules, such as metastasis, sarcoidosis and hyalinising granuloma. We report a 60-year-old man who presented to the Royal Hospital, Muscat, Oman, in 2017 with a history of shortness of breath upon exertion, orthopnoea and bilateral lower limb swelling. A chest X-ray showed bilateral nodular opacities. Enhanced chest computed tomography revealed bilateral pulmonary nodules with a predominantly perilymphatic and subpleural distribution, giving the impression of a neoplastic nodule. A histopathological examination of biopsied lung tissue confirmed a diagnosis of nodular pulmonary amyloidosis.

Pulmonary hyalinising granuloma (PHG) is a rare fibrosclerosing inflammatory lung condition of unknown aetiology. It is characterised by solitary or multiple pulmonary nodules that are usually found incidentally while imaging the chest for other reasons. We report two cases of histologically proven PHG diagnosed at the Royal Hospital, Muscat, Oman. The first case was a 71-year-old male patient who presented in 2010 with a dry cough, weight loss and bilateral pulmonary nodules. The second case was a 58-year-old male patient who presented in 2012 and was found to have incidental bilateral pulmonary nodules on chest X-ray. Both patients were started on prednisolone and on follow-up the PHG nodules remained stable. Although there is no definitive treatment, PHG generally has an excellent prognosis.
