Disseminated multiple hydatidosis at unusual location: Two rare case reports.

Hydatid disease, a parasitic infection is caused by cestode tapeworm Echinococus granulosus which is endemic in cattle grazing areas including India. Dogs are the definitive host. In human, commonly involved organs are liver and lungs. Peritoneal hydatidosis secondary to liver hydatid diseases is not uncommon but peritonial hydatidosis herniating to inguinal canal mimicking irreducible inguinal hernia is rare. Patient on clinical examination appears normally with complain of progressive abdominal pain and distention and irreducible cystic swelling in the inguinal region. Patients also gave history of contact with animals. Laboratory findings were not constant. Imaging and investigation necessary for establishing diagnosis were done. There always choice between ultrasound and computed tomography. Treatment includes conservative and surgical intervention. In case of single, symptomatic and large cyst was surgically treated. Small asymptomatic cysts, some daughter cysts, and peritoneal secondary cysts and splenic cysts may also be effectively conservatively treated. We reported here two cases of multiple hydatidosis at unusual location. In all patients large and symptomatic cyst was excised and all patient recover clinically. This case series emphasized that current understanding of disseminated multiple hydatidosis etiology still very little known. Study for additional risk factor may be necessary.

CT-guided 125I seed implantation for retroperitoneal lymph node metastases：its technical points / 介入放射学杂志

Objective To introduce several commonly used puncture techniques for retroperitoneal lymph node metastases in order to provide technical guidance in performing 125I seed implantation therapy. Methods The puncture methods used at authors’ interventional department in performing 125I seed implantation therapy for retroperitoneal lymph node metastases were summarized. Results The commonly used puncture methods included parallel needle puncturing technique , trans-viscera puncturing technique , broadening path puncturing technique and coaxial needle puncturing technique. Conclusion An effective combination use of various puncturing techniques to uniformly implant the radioactive 125I seeds into the lesion can improve the therapeutic result and reduce the occurrence of complications.
