A 42-year-old male presented with pain in the epigastrium, radiating to the back and feeling of fullness of the abdomen for a duration of six months. He gave history of loss of appetite and weight loss of 5 kg over a period of six months. He complained of progressive breathlessness on exertion for a period of one month. He gave no history of cough, expectoration, fever, wheeze or hemoptysis. He did not give any history of trauma.\nHe was working as a casual laborer in the agriculture sector. He consumed alcohol on at least five days in a week and smoked at least two packets of beedis in a week.\nNine months back he was admitted to a hospital for treatment of acute abdominal pain. A diagnosis of acute on chronic calcified pancreatitis was made. The most probable cause for the chronic pancreatitis was due to excessive alcohol intake by the patient. A pancreatoduodenostomy was performed on him. He remained asymptomatic for a period of three months. A follow-up ultrasound done after three months showed multiple calcification of the head of the pancreas with bulky tail, and minimal ascites and one old calcified granuloma in the right lobe of the liver. He was put on a low-fat diet, small frequent feeds and received pancreatic enzyme supplements from the time he was operated upon.\nOn examination he was thin built and emaciated and was systemically well. There were no palpable lymphadenopathies. He had bilateral pitting pedal edema. On chest examination there was diminished movement of the right lower hemithorax when compared to the left. Percussion of the right hemithorax yielded a dull note in the right infraaxillary and infrascapular areas which persisted on deep inspiration. On auscultation diminished breath sounds in the right basal regions were apparent. On palpation his abdomen was distended, epigastric tenderness was present and bowel sounds were heard. Examinations of other systems were unremarkable.\nHis hemogram revealed low hemoglobin of 9.2 mg/dl and elevated erythrocyte sedimentation rate of 32 mm in half hour. Renal and liver function tests were within normal limits. Sputum smear examination for acid-fast bacilli was negative in the two samples obtained. The result of the Mantoux test done with 5 TU and read after 48 h was 0 mm. Peripheral smear examination for microfilaria was negative. Chest skiagram revealed apparent elevation of right hemidiaphragm with lateral peaking, a heterogeneous opacity in the right lower zone and loss of lung volume on the right hemithorax. A lateral decubitus view revealed tracking of fluid.\nUltrasonogram of chest was done and pleurocentesis was performed at the site marked for pleural fluid aspiration. The pleural fluid aspirated was milky white in color and odorless [ and ].\nWith pleural fluid triglyceride >110 mg/dl and pleural fluid to serum cholesterol ratio less than 1 a diagnosis of chylothorax was made.[] Pleural fluid cytology was negative for malignant cells. Ziehl-Neelsen staining of pleural fluid smear was 3 plus positive for AFBs []. Computed tomography (CT) scan of the chest showed right-sided hydrothorax with partial collapse of the right lower lobe and fluid in minor fissure []. CT scan of abdomen was suggestive of acute on chronic pancreatitis with ascitis. Ascitic fluid was so minimal that ascitic fluid aspiration could not be done. It did not reveal any evidence of mass lesion or enlarged lymph nodes.\nThe patient was started on antituberculous treatment with a four-drug regimen with isoniazid, pyrazinamide, rifampicin and ethambutol. He did not give consent for intercostal drainage or any surgical or interventional procedure, hence pleural aspiration was done in a staggered manner in three sittings with 500 ml being aspirated in each sitting. As octreotide was not available in our institution he was put on a low-fat diet, intravenous fluids and monitored. The patient's general condition improved and he was discharged from the hospital after three weeks.
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 ().
