“…Less commonly it has also been reported in the residual cavity after surgery for pulmonary hydatid cyst . This double pathology may be clinically asymptomatic or manifest with symptoms similar to that of present case. It has been proposed that superinfections by such opportunistic pathogens occur when large hydatid cysts extend to or lie close to the hilum that prevents obliteration of the cyst cavity and facilitates its superinfection from the adjacent airways .…”

“…It is also well known that presence of cavitary lesions in lung is a predisposing factor for infection by the saprophytic fungus Aspergillus . Yet, co‐existence of pulmonary echinococcosis and aspergillosis is rare, with most of the reported cases and short case series being histopathological diagnosis . Till date, there are only two documented reports of this double pathology being diagnosed on cytology .…”

Pulmonary hydatid cyst with co-existing aspergillosis is rare. Till date, there are only two documented reports of this double pathology being diagnosed on cytology. The present case is of a young immunocompetent female who presented with respiratory complaints including intermittent hemoptysis. Chest X-ray and CT thorax revealed two well-defined lesions in the lower lobe of left lung that was suggestive of either infective or benign neoplastic etiology. But as hydatid cyst was not suspected either clinically or radiologically, FNA was performed. Based on the typical cytomorphological features a definitive diagnosis of hydatid cyst with aspergillosis was offered on cytology that was later confirmed on histopathology. To the best of our knowledge this is only the third report of pulmonary echinococcosis with aspergillus co-infection being diagnosed on cytology. The purpose of reporting this case is to draw attention to the rare possibility of co-existing aspergillus infection in pulmonary echinococcosis even in immunocompetent individuals, which can complicate the clinico-radiological picture. However, both pathologies can be effectively and accurately diagnosed on cytology, based on which proper treatment can be initiated. Diagn.

“…This may explain its presence in trace amounts in all samples. On the other hand, in the present work, reagent strips yield positive results of >10 granulocytes in 8 HCF samples denoting infection which certainly affects viability of the larval stage and unfortunately can be a main cause of mortality in cystic hydatidosis (García et al, 2010). The identifi ed microorganisms were Escherichia coli, Enterococcus spp.…”

SummaryThe aim of the current work was to evaluate the possibility of using a rapid and simple reagent strip test to investigate the viability of hydatid cysts intraoperatively, via testing certain biochemical parameters. Thirty eight HCF samples were processed and examined by different methods for determining the viability status. Using the reagent strip test in the current study, the highest signifi cant level of glucose was detected in HCF samples with the highest viability % at pH 7.5 and the lowest signifi cant level of glucose was detected in HCF samples with the lowest viability % at pH 8.5, indicating a likely correlation between glucose concentration and the viability of PSs. On the contrary, protein was not detected in HCF containing viable PSs and was found to be higher in HCF containing non-viable PSs, denoting the possible degenerative processes in such PSs. Haemoglobin was found in trace amounts in all of our samples. In addition, the strip test detected bacterial contamination in 8 samples and biliary leakage in 7 samples. Our results suggest that the simple reagent strip test can assist in providing fast, uncomplicated primary data regarding the viability status of the hydatid cysts. Thus, it may aid the surgeons to make informed decisions for further management and appropriate follow up to minimise the risk of post-operative recurrence.

“…PHCs may remain asymptomatic for long time as elastic capability of the lung without any resistance give leverage for growth. Complications include super-infection, bacterial and fungal as well [6] and rupture-spontaneous or iatrogenic (FNAC or Percutaneous aspiration). Surgery is still the treatment of choice which includes simple cystectomy, pleural cavity washings, and major decortication to lung resection.…”

We report herein a successful management of a case of 24-year-old unmarried male presented to us with the complicated left pulmonary hydatid cyst as left empyema thoracis who eventually developed further thoracic and abdominal complications after the surgical removal of one big hydatid cyst from left lung and two big hydatid cysts from both lobes of liver. The importance of unwearied approach of clinicians and successful applications of multi-modality conservative, interventional, medical and surgical procedures are also discussed for the best outcome of this subset of patients.
