Female patient aged 75 years who had no history of chronic disease apart from depression presented at outpatient clinic with complaints of lassitude, loss of appetite, exertional dyspnea for 4 months, and dry coughing for 2 months. Her examination revealed marked decrease in respiratory sounds at basal segments of the right lung. Hematological values, sedimentation, glucose, urea, creatinine, sodium, potassium, total protein, and albumin levels were within normal limits. Levels of alanine aminotransferase (189 U/L), aspartate aminotransferase (113 U/L), cholesterol (251 mg/ dL), and lactate dehydrogenase (LDH) (193 U/L) were also measured. X-ray graphy revealed a dark shadow, consistent with pleural fluid masking the demarcation line between mediastinum and pleura at the inferior zone of the right lung (). Thoracic computed tomography (CT) revealed multiple sites of lymphadenopathy, the largest containing dense calcification 22 mm in size, and marked pleural effusion on the right side (). Milky fluid with high density sampled from pleural effusion did not precipitate after centrifugation, and contained TG (1072 mg/dL), cholesterol (173 mg/dL), LDH (148 U/L), and albumin (2.7 g/ dL) at indicated concentrations. Sudan staining disclosed presence of fat globules. Lymphocyte dominancy was also detected in pleural fluid. Sputum ARB -negativity was detected 3 times, and bronchoscopy of the patient did not reveal any endobronchial pathology. Pleural biopsy was performed. Bronchial lavage and bronchoscopic biopsy results indicated benign condition of chronic pleuritis. Positron emission tomography-CT was obtained to rule out mediastinal tumor. During lymphatic scanning performed to detect etiology of chylothorax, images taken at second, fourth, and sixth hours demonstrated passage of radiographic contrast substance through bilateral inguinal, parailiac, paracaval, and paraaortic lymph nodes, and accumulation of radioactivity in these lymph nodes at popliteal, femoral, and pelvic regions, respectively. On delayed thoracic images, no uptake of radioactivity apart from background activity was observed. Images suggested possible thoracic duct obstruction. Mediastinal lymph node biopsy performed at external center revealed presence of granulomas demonstrating caseous necrosis. Abdominal ultrasound was normal. Antituberculosis treatment was initiated. Symptoms regressed with treatment, and level of liver enzymes decreased. At sixth month, marked regression in pleural effusion was observed ().
A 33-year-old man, diagnosed case of chronic kidney disease secondary to diabetes mellitus on maintenance dialysis presented to pulmonary medicine outpatient unit with complaints of intermittent fever and weight loss of 2 months duration. On examination, he was febrile (38.4 Celsius) with a respiratory rate of 20/min, pulse rate of 104/min, blood pressure of 140/90 mmHg, and oxygen saturation of 96% on room air. General examination revealed pallor and bilateral pitting pedal edema. His respiratory-, cardiac-, abdominal- and neurological examination was within normal limits. Laboratory examination showed hemoglobin of 7.2 g/dL (normal 11.5–16.5), platelet count of 22 × 109/L (normal 150–500), white cell count of 3.2 × 109/L (normal 4.3–10.8) with neutrophils 65%, lymphocyte 32%, and monocyte of 3%. His glycated hemoglobin was 5.6% (normal <6.5%) and liver function test revealed albumin of 2.2 g/dL (normal 3.5–5 g/dL). Rest of the biochemical investigations were within normal limits. HIV serology was negative. Even though, the patient had normal blood picture and reticulocyte count, bone marrow study was done for his leukopenia.\nChest X-ray posteroanterior (PA) view revealed increased bronchovascular markings [] and computed tomography (CT) thorax with abdomen [] showed bilateral mild pleural effusion with significant mediastinal and abdominal adenopathy. Ultrasound chest was done and it revealed minimal pleural effusion and the same was not tappable. CT-guided fine-needle aspiration was done from paraaortic lymph nodes. Histopathology from bone marrow and cytology of paraaortic lymph nodes showed caseous necrotic granulomatous inflammation suggestive of TB. Acid-fast culture of bone marrow tissue and lymph node aspirate revealed growth of pansensitive mycobacterium TB. He was initiated on modified antitubercular treatment for his kidney disease and the regimen included rifampicin 450 mg daily, isoniazid 300 mg daily, ethambutol 800 mg thrice weekly, and pyrazinamide 1250 mg thrice weekly.\nSix weeks postantitubercular treatment, he came to our casualty with complaints of fever and exertional breathlessness. Patient was febrile (38.6°C) with respiratory rate of 32/min, pulse rate of 120/mine, blood pressure of 150/92 mm of Hg, and oxygen saturation of 92% at room air. Respiratory examination was suggestive of right pleural effusion. Rest of the examination was within normal limits. Chest X-ray PA view showed features suggestive of right moderate to massive pleural effusion []. Diagnostic thoracocentesis revealed milky white fluid and analysis showed total protein 4.1 g/dL, glucose 117 mg/dL, total cholesterol 68 mg/dL, triglycerides 751 mg/dL, and chylomicrons 1050 mg/dL. Cytology of the pleural fluid was negative for malignant cells, cultures for bacteria and mycobacteria were negative. Hence, a diagnosis of chylothorax was made. Repeat CT thorax with abdomen showed an increase in the size of mediastinal and abdominal lymphadenopathy. Hence, the acute worsening in patient clinical condition was attributed to be part of PR/IRIS, developing secondary to antitubercular treatment. His antitubercular therapy was continued and was managed symptomatically with parenteral nutrition, therapeutic thoracocentesis, antipyretics, and oxygen; nonsteroidal anti-inflammatory drugs were deferred in view of renal disease. Despite these he was symptomatic, so initiated on tab prednisolone 1 mg/kg/day. In view of persisting breathing difficulty, increasing oxygen requirement and worsening pleural effusion radiologically after informed consent intercostal drain (ICD) was inserted. Post-ICD X-ray showed partial expansion of lung, so patient was connected to −20 cm water suction. Despite these lung failed to expand, thoracic surgery opinion was obtained and he underwent decortication and interruption of the thoracic duct. Histopathology of the operated specimen showed fibrous connective tissue, fibrinous, and acute inflammatory exudates. Postoperative chest X-ray showed good lung expansion and resolution of right pleural effusion []. Prednisolone 1 mg/kg daily was continued for 2 weeks, then, it was tapered to 0.5 mg/kg and the same was given for 2 more weeks. The patient was discharged on antitubercular treatment and was advised to continue the same for total of 6 months. On follow-up, patient showed good clinical recovery.
