Pulmonary artery pseudoaneurysm secondary to COVID-19 treated with endovascular embolisation.

Pulmonary artery pseudoaneurysms are uncommon and can cause severe, life-threatening haemoptysis. We present a case of a 74-year-old gentleman who was being treated for COVID-19 pneumonitis and a concomitant segmental pulmonary artery thrombus with conventional treatment and anticoagulation. The patient developed significant haemoptysis during admission.

Prevalence and Effects of Emphysema in Never-Smokers with Rheumatoid Arthritis Interstitial Lung Disease.

Aims: Autoimmune conditions such as rheumatoid arthritis-related interstitial lung disease (RA-ILD) have been linked to the existence of emphysema in never-smokers. We aimed to quantify emphysema prevalence in RA-ILD never-smokers and investigate whether combined pulmonary fibrosis and emphysema (CPFE) results in a worsened prognosis independent of baseline disease extent.

Methods: RA-ILD patients presenting to the Royal Brompton Hospital (n=90) and Asan Medical Center (n=155) had CT's evaluated for a definite usual interstitial pneumonia (UIP) pattern, and visual extents of emphysema and ILD.

Inflammatory myofibroblastic tumour of the lung: a reactive lesion or a true neoplasm?

Inflammatory myofibroblastic tumour (IMT) of the lung represents an extremely rare type of inflammatory pseudo tumor that appears most commonly in children and young individuals. There has been an ongoing controversy whether an IMT is a reactive lesion or a true neoplasm making the further management extremely challenging. Purpose of the paper is through a literature review to highlight the existence of this rare tumour along with its key features and the management options available.

Primary synovial sarcoma of the lung: can haemothorax be the first manifestation?

Primary pulmonary synovial sarcomas represent a rare clinical entity and account for approximately 0.5% of lung malignancies. We report the case of a 30-year-old male who presented clinically with haemothorax.

Primary mucoepidermoid carcinoma of the thymus presenting with myasthenia gravis.

Mucoepidermoid carcinoma (MEC) of the thymus is a rare malignant neoplasm of the anterior mediastinum. There are less than 30 cases described in the English literature. We report a case of a 47-year-old lady who presented with myasthenia gravis and was found to have a well-circumscribed anterior mediastinal mass in her medical work-up.

The challenging management of lung choriocarcinoma.

The purpose of this paper is to highlight the existence and the management of lung choriocarcinoma (CCA), a rare category of lung tumors. We present a 42-year-old female that presented to our department with a PET positive lesion in the left upper lobe and a history of pregnancy 6 months prior to onset of symptoms. CT guided biopsy was inconclusive for diagnosis and the patient underwent a left thoracotomy and lingula sparing upper lobectomy.

The S-cone contribution to luminance depends on the M- and L-cone adaptation levels: silent surrounds?

Under dim background conditions, the S-cones make little or no contribution to luminance (A. Eisner & D. I.
