Miliary pattern on radiographs are attributed always to tuberculosis even though the differential diagnoses of miliary pattern is very wide. This pattern is most commonly caused by infectious diseases and rarely by malignancies. Primary lung cancers presenting with miliary shadows is extremely rare. Here we report a case of 50-year old female, presenting with 15 days of symptoms and CXR PA view showing bilateral diffuse miliary nodules. HRCT Chest confirmed the miliary pattern and also showed a mass in left lower lobe. Microbiological tests for tuberculosis and fungal infections were negative. CECT Chest gave impression of left lower lobe suspected malignant lung mass with pulmonary metastasis. Malignancy was confirmed by CT guided FNAC as Adenocarcinoma lung. PET scan didnot reveal metastasis in other organs. CONCLUSION : Miliary pattern does not always indicate tuberculosis and other possibilities should be evaluated.

The effects of changing cardiac output and lung mass on pulmonary capillary surface area, lung water, and hemodynamics were studied in eight sheep. 51Cr-erythrocytes, 125I-albumin, 3H2O, and [14C]urea were injected into the right atrium, and timed samples were collected from the aorta for the calculation of cardiac output (CO), extravascular lung water (EVLW), and permeability-surface area product (PS) for [14C]urea. CO was varied by opening and closing arteriovenous shunts, and lung mass was decreased by first tying off the left lung followed by tying off the right lower lobe. Pulmonary arterial pressure (r = -0.741) and pulmonary vascular resistance (r = -0.700) increased as lung mass was decreased. CO decreased slightly (r = -0.470 while left atrial pressure was not changed (r = -0.144) by decreasing lung mass. There was a close correlation between EVLW and lung mass (r = 0.944) and between [14C]urea PS and lung mass (r = 0.672). We were able to demonstrate that [14C]urea behaves as a diffusion-limited tracer in a single pass through the lungs, since [14C]urea extraction decreased as flow per unit mass increased. These results support the clinical use of multiple-tracer studies to measure EVLW and [14C]urea PS.

A 46-year-old man presented with nonproductive cough and lower limb swelling. Chest radiograph showed a left lower lobe lung mass and multiple subpleural nodules. Other investigations revealed that he had nephrotic syndrome. Core biopsies of the left lower lobe lung mass showed features of inflammatory pseudotumor with endarteritis obliterans and a lymphoplasmacytic infiltrate. Immunohistochemical stain for Treponema pallidum was positive. Resolution of the lung mass and nephrotic syndrome was achieved after treatment with intramuscular benzathine benzylpenicillin. The differential diagnosis of pulmonary inflammatory pseudotumor, manifestations of pulmonary syphilis, and a literature review of secondary syphilis of the lung are discussed.

Background: Lymphomatoid granulomatosis (LYG) is a rare Epstein-Barr virus (EBV)-driven lymphoproliferative disease. LYG is characterized by a progressive clinical course, which virtually always involves the lungs. LYG characteristically presents as bilateral pulmonary nodules. Pathologically, it is characterized by an angiocentric and angiodestructive infiltration of atypical EBV-positive B-lymphocytes admixed with reactive T-lymphocytes. We report a case of pulmonary LYG that presented as a large mass with complete occlusion of the right main stem bronchus intermedius in an 81-year-old female. Case: An 81-year-old female presented with shortness of breath to the emergency department. Inpatient imaging revealed bulky mediastinal lymphadenopathy with a right lower lobe collapse, shift of the cardiomediastinal silhouette, and a large right upper lung mass. Endobronchial ultrasound-guided biopsy (EBUS) revealed complete occlusion of right mainstem bronchus due to the right upper lung mass growth into the bronchus intermedius. Histopathological examination demonstrated clusters of large atypical EBV-positive B cells interspersed in a minimally polymorphous lymphocytic background, consistent with lymphomatoid granulomatosis, grade 3/3. Patient was treated with immunochemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone - CHOP) and Rituximab (anti-CD20 antibody). At the patient’s most recent follow-up, 6 months later, she was in a stable condition and her respiratory symptoms have improved. Conclusion: Lymphomatoid granulomatosis is a rare disease that should be considered in the differential diagnosis of a radiographic evaluation of a solitary pulmonary lung mass. Since the radiographic impression might favor carcinoma as the top differential diagnosis, biopsy of the lesion is paramount to ensure the correct diagnosis. Lymphomatoid granulomatosis is usually treated with an immunochemotherapy regimen with CHOP, and/or interferon, and Rituximab.

This case reports a 54-year-old lady with a chest X-ray showing a lung mass that was later identified to be eventration or abnormal elevation of a part of the diaphragm. This article discusses eventration of the right diaphragm and liver herniation, that although relatively rare, has characteristic radiological appearances.

Partial Pleurectomy

A 60-year-old man was referred to the interventional pulmonology clinic with a large right-sided intraparenchymal lung mass and a second, smaller lesion in the left lower lobe, accompanied by intermittent haemoptysis, fever, chills, productive cough of white phlegm as well as dizziness and weakness. He had presented previously and was being evaluated for the possibility of malignancy. Investigations had revealed ‘hooklets’ (protoscolices) of hydatid cysts, most likely representing the parasite Echinococcus. Successful surgical excision of the affected lobe, lung decortication, partial pleurectomy and pneumolysis of the adhesions was performed, along with long-term antiparasitic therapy. The initial differential diagnosis for this patient was challenging and required multimodal investigations. The patient made good recovery and continued to be followed by infectious disease specialists for management of antiparasitic therapy.

Mycobacterium avium complex (MAC) is a non-tuberculous mycobacteria (NTM) that causes subacute or chronic nodular bronchiectasis, cavitary or fibro-cavitary pneumonia in patients with chronic structural lung pathology including emphysema, chronic bronchitis, and bronchiectasis. It is also known to cause pulmonary and extrapulmonary infections in patients with impaired cell mediated immunity such as transplant recipients, (Acquired Immune Deficiency Syndrome) AIDS where it can cause disseminated infections. Empyema from MAC has been reported in immunocompromised patients and is a rare phenomenon. Here we report a patient who presented with chronic left pleural effusion and a left lower lobe lung mass that went undiagnosed for 2 years, despite extensive work-up. Later in his course, he presented with a large effusion complicated by a bronchopleural fistula and was diagnosed as MAC empyema. To our knowledge, this is the first case of MAC empyema, that presented as a chronic lung mass, complicated by a bronchopleural fistula. In this article, we present the clinical, laboratory, and radiological features, with emphasis on a combined medical and surgical approach in the management of MAC empyema. We also provide a brief overview of cases of MAC associated pleurisy and empyema that have been reported in literature.
