Abstract: Orbital metastasis is a rare entity in oncology. With increasing awareness and advancement, patients with initial ocular presentation can be diagnosed and treated. Ocular metastasis is more common in breast cancer followed by lung cancer. Lung cancer with ocular presentation generally have poor prognosis because of difficult diagnosis, Vision impairment and delayed management. Here, we report one such case of 59 year old female presented with painful periorbital swelling in left eye for 3 months with no pulmonary symptoms. On evaluation, she was diagnosed as ocular metastasis with primary being lung adenocarcinoma. Through this case, we enlighten the epidemiology, presentation, clinical features and evaluation of such patients which might help clinicians in further management.

Background: Studies conducted in interstitial lung disease (ILD) patients to assess diaphragmatic excursion and thickening fraction suggest a weak to strong correlation with pulmonary function parameters. However, diaphragmatic excursion velocity, a novel imaging marker, has not been correlated with pulmonary function and high-resolution computed tomography (HRCT) fibrosis score in ILD patients previously.

Methods: We conducted a cross-sectional analytical study in 40 ILD patients during quiet (QB) and deep breathing (DB) to measure diaphragmatic thickening, excursion and excursion velocity using transthoracic ultrasound and correlated them with pulmonary function parameters and HRCT fibrosis score.

Results: Most diaphragm parameters in DB correlated more strongly with lung function parameters compared to quiet breathing. Right diaphragmatic excursion, during QB and DB, showed positive correlations with forced vital capacity (FVC) z-score (r = 0.591, 0.676) and diffusion capacity of the lung for carbon monoxide (DLCO) z-score (r = 0.437, 0.438), and negative correlations with HRCT fibrosis score (r = -0.439, -0.425), respectively. In addition, right diaphragmatic velocity exhibited positive correlations with FVC z-score (r = 0.388, 0.667) and DLCOz-score (r = 0.139, 0.412), and negative correlations with HRCT fibrosis score (r = -0.454, -0.445). Right diaphragm thickening fraction showed positive correlations with FVC z-score (r = 0.330, 0.460) and DLCOz-score (r = 0.400, 0.426), and negative correlations with HRCT fibrosis score (r = -0.199, -0.237). Similarly, right diaphragmatic thickness indicated positive correlations with FVC z-score (r = 0.526, 0.614) and DLCOz-score (r = 0.298, 0.298), and negative correlations with HRCT fibrosis score (r = -0.398, -0.401).

Conclusion: Diaphragmatic excursion velocity during DB showed a weak to moderate correlation with pulmonary function parameters and HRCT fibrosis score and may be utilized as a surrogate marker in ILD patients unable to perform pulmonary function tests or undergo sequential HRCT thorax in follow-up.

Abstract: Bronchial varices, characterized by dilated and tortuous vessels within the bronchial tree, are a rare entity often presenting as massive or recurrent haemoptysis. Multiple aetiologies have been described in the literature including congenital or acquired pulmonary vein stenosis secondary to surgical or radiofrequency ablation or other cardiac interventions. We present a case of a 60-year-old female with a history of systemic hypertension, hypothyroidism and sick sinus syndrome, who presented with intermittent episodes of dry cough and haemoptysis. A diagnostic workup revealed circumferential bronchial thickening and pulmonary vein stenosis on contrast-enhanced chest computed tomography (CT). Bronchoscopic findings confirmed the presence of bronchial varices, which was secondary to the Radiofrequency ablation she underwent 7 years ago. This case highlights the diagnostic challenge posed by bronchial varices and underscores the importance of a comprehensive approach in managing such rare presentations.
