Radiologic Features of Hydatid Disease

Abstract

Hydatid disease is commonly encountered in specific geographic areas of the world. Hydatidosis affects multiple organs and has diverse radiologic presentations. Sonography remains an important modality for diagnosing this condition, as it optimally detects cystic structures, floating membranes, and debris. Sonography forms the crux of radiologic diagnosis of hydatid disease. It not only helps diagnose the disease but also aids in guiding therapeutic interventions. The main objective of this article is to describe the imaging features of hydatid disease in its various stages. This article gives an overview of the spectrum of sonographic manifestations of hydatid disease in various locations, along with common differential diagnoses. A brief description of therapeutic management is also presented.

Presentation of secondary parasitic infection 37 years after primary infection

“…Humans are opportunistic intermediate hosts only [3] and are unable to spread the parasitic infection. Upon consumption parasitic eggs are absorbed via intestinal mucosa, enter the portal circulation and/or lymphatics [1] and finally reside in viscera, most commonly the liver and lung [6]. Secondary visceral infection occurs due to intraperitoneal cyst rupture or systemic dissemination [6].…”

“…The most common presenting complaints with intra-abdominal cystic echinococcosis are pain, fever, jaundice, nausea, vomiting and weight loss [2, 3]. Symptoms may be due to visceral compression, secondary cyst infection or rupture [6]. Intra-abdominal cyst rupture results in release of highly immunogenic hydatid fluid with potential peritoneal seeding [6] and anaphylaxis which is associated with greater mortality [10].…”

“…G1 is responsible for most human cystic echinococcosis (88.44%) with its origin being hypothesized to the Middle East [2]. Cystic echinococcosis disease is a neglected pathology [1, 5] that primarily affects the liver [2] and lung [1, 3–6]. Our patient presented with secondary infection involving pelvic viscera and peritoneum.…”

“…Our patient presented with secondary infection involving pelvic viscera and peritoneum. Infection results in major morbidity [1] and remains a huge health issue [6] due to its chronicity [7], life threatening sequelae [1] and possible mortality if untreated [3]. …”

Anaphylactic Shock Diagnosed with Bedside Abdominal Ultrasonography and Computerized Tomography

“…Hydatid cyst disease is classified into four types on the basis of their CT Features. Type IV: Various features depending on site of rupture [5].…”
