Pulmonary hydatidosis in a tertiary care hospital

Abstract

Background:Hydatid disease is caused by the larval stage of Echinococcus. Liver is the most commonly involved organ followed by the lungs. Pulmonary hydatidosis can be primary or secondary. The disease may be asymptomatic for several years. Cause of concern is the fatal anaphylaxis, which may be life threatening.Materials and Methods:The present retrospective study is over a period of ten years (2003-2012). The demographic data including the clinical features, radiological findings, other organ involvement, surgical and medical management done and histopathological findings were compiled from the records.Results:During the study period a total of eight cases, five male and three female, with age ranging from eight to 43 years were diagnosed as pulmonary hydatid disease. Five patients had presented with complicated cysts. Six patients had solitary cysts involving the lung while bilateral lung involvement was seen in two cases. One patient had multiple pulmonary cysts. Three patients had associated cysts in liver and two in spleen. Surgical lobectomy was done in four cases. Histopathology showed acellular laminated ectocysts in all the cases, whereas endocyst with brood capsules was seen in five cases.Conclusions:Pulmonary hydatidosis is not uncommon. Anaphylaxis, although rarely seen, may be a disastrous event. High index of clinical suspicion and mass awareness for interruption of transmission of parasite can lead to proper treatment and possible eradication.

Hydatid cyst of the lung: a case report from Sri Lanka

“…Moreover, a retrospective study analysing data over 10 years from Punjab, India, had found 8 patients with pulmonary hydatidosis, with six of them having solitary cysts while other two had bilateral lung involvement. Three have had associated cysts in the liver and spleen, while 4 had been treated with surgical lung lobectomies (10). Another case report by Teo et al describes a rare solitary pulmonary hydatid cyst in a 37-year-old Indian lady from Singapore, where she had presented with allergic manifestations following a rupture of the cyst and hydatid fluid leakage (6).…”

Single-center experience in the surgical treatment of combined lung Echinococcosis

“…Large cysts require certain management of the residual space to avoid postoperative dissemination through air and formation of empyema. 19 , 20 …”

Basic Operative Tactics for Pulmonary Echinococcosis in the Era of Endostaplers and Energy Devices

“…Pulmonary echinococcosis (PE) is a variant of the disease, in which parasites form lesions in the lungs. The pathogenesis of PE may involve bypassing the liver (primary PE) or metastatic-like spread from the liver (secondary PE) [ 2 ]. Primary or secondary PE is a clinically challenging condition in which anthelminthic regiments are important, but surgery has the central role in removing the cysts and preventing recurrences [ 3 ].…”
