A 24-year old male developed left sided pleural effusion 10 days after the start of anti tubercular chemotherapy for right-sided pleural effusion and parenchymal lesion. This effusion seemed to be a paradoxical response as it resolved on follow up.
Patient: Female, 32Final Diagnosis: Complicated hydatid cystSymptoms: Cough with expectoration and fever for the last 4 monthsMedication: Tab. AlbendazoleClinical Procedure: —Specialty: PulmonmologyObjective:Unusual clinical courseBackground:Hydatid cyst, or Echinococcosis, is an important helminthic zoonotic disease in humans that commonly affects the liver and lungs. Uncomplicated hydatid cysts, seen as round opaque lesions on chest radiography, are easily diagnosed, whereas complicated cysts (infected and or perforated) may change the radiographic appearance of the hydatid cyst, causing an incorrect diagnosis and delayed treatment. Although in radiology many signs have been described, the “air bubble” sign, seen in the mediastinal window of CECT as a single or multiple small rounded radiolucent areas with sharp margins within the periphery of a solid mass lesion, is being recognized as a sign with high sensitivity and specificity in the diagnosis of complicated hydatid cysts.Case Report:A 32-year-old female on anti-tubercular treatment for the past 3 months without any improvement was admitted to our hospital. CECT of the chest revealed a mass-like lesion with the “air bubble” sign. After 15 days the patient had a vigorous bout of coughing, leading to expectoration of pieces of whitish yellowish gelatinous membrane for the next 3 days. The ELISA result for Echinococcus was highly positive. On the basis of the “air bubble” sign, positive serology, and expectorated pieces of the membrane, the patient was diagnosed as having a complicated hydatid cyst.Conclusions:Due to the varied presentations of complicated hydatid cyst, the knowledge and awareness of various signs in radiology associated with the hydatid cyst, in particular the “air bubble” sign, is imperative in making a prompt and accurate diagnosis of a complicated hydatid cyst.
A case of bilateral eosinophilic pleural effusion with coincidental intestinal infestation of giardia lamblia is being reported. After reviewing the possible causes of this type of pleural effusion, no clinical or laboratory data were obtained which could explain this condition except giardiasis. Moreover the clearance of pleural effusion with the treatment of giardia with metronidazole suggests giardia as the probable cause of bilateral eosinophilic pleural effusion.
Pulmonary hypoplasia, a congenital malformation, is characterized by incomplete development of the lungs, leading to an abnormally less number or dimensions of bronchopulmonary segments / alveoli resulting in small fibrotic and nonfunctional lung. It is usually diagnosed in the neonatal period or in early childhood. Hypoplasia may be primary (idiopathic) or secondary. Primary pulmonary hypoplasia, not related to other congenital anomalies is extremely seldom diagnosed in adults. We report the case of a 32-year-old married female with two kids presented to us with chief complaints of cough and fever for past nine months. Chest radiograph showed opacification of the left hemi-thorax with decrease in its size and marked ipsilateral mediastinal displacement with an increase in volume of right lung. After investigations she was diagnosed as a case of left lung primary pulmonary hypoplasia. High level of excellent clinical judgement needed to spot and diagnose this congenital aberration, often wrongly diagnosed in adults. Hence, once confronted with an opaque hemi-thorax in a young person with ipsilateral shift of the mediastinum, differential diagnosis of "lung hypoplasia" ought to be kept in mind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
