Hydatid cysts of the spleen are rare. Our report details a case wherein an 8-year-old boy with a ruptured splenic hydatid cyst suffered ongoing abdominal pain and shock. Computed Tomography (CT) imaging showed an irregular cyst at the spleen\'s lower edge with a \"floating membranes\" sign. Emergency surgery was performed to remove the hydatid cyst and repair the ruptured spleen. During follow-up, the patient was treated with Albendazole orally for 12 months.

BACKGROUND: Human hydatid disease typically occurs in organs such as the liver and kidney. Primary solitary intramuscular hydatid disease, however, is rare.
METHODS: We report a case of a giant muscle hydatid in the lower extremity, with neurological symptoms as the first manifestation. The symptoms specifically manifested as intermittent pain in the right lower extremity and numbness in the sole of the right foot. However, there were no obvious abnormalities detected in electromyography and lumbar MRI. Subsequent ultrasonography and calf MRI showed that the patient had cystic lesions in the calf. The patient was initially diagnosed with a muscle hydatid cyst. Treatment involved complete surgical excision of the lesion, and the diagnosis of a hydatid cyst was confirmed through macroscopic and microscopic histopathological examination after the mass was excised. The patient was given oral albendazole, and no recurrence was observed during the 12 months of follow-up.
CONCLUSIONS: This case underscores the need to consider hydatid disease when diagnosing soft tissue masses in muscles, particularly in endemic areas. Patients may initially present with atypical symptoms like peripheral nerve issues.

OBJECTIVE: The purpose of this study was to evaluate the outcomes of multiple debridement of cavity lesion combined with anti-parasitic chemotherapy in the treatment of mid or advanced spinal echinococcosis, and to document the complications, bone and functional outcomes.
METHODS: From January 2007 to February 2019, the medical records and imaging were evaluated retrospectively of all patients with mid or advanced spinal echinococcosis, who were treated by multiple debridement of cavity lesion. The Braithwaite and Less classification system of spinal echinococcosis and the Frankel Classification System was utilized evaluate the results of preoperative and postoperative recovery.
RESULTS: Between January 2007 to February 2019, a total of 33 patients met the criteria were included in this study with a mean postoperative follow-up time of 4.9 (1 to 10) years. There were 18 males (54.5%) and 15 females (45.4%), with a mean age of 41.5 years (range, 23 - 70 years). The satisfactory recovery of lower limb motor function were presented in 32 patients. Of the 24 patients (72.7%) with recurrence of spinal echinococcosis.
CONCLUSIONS: Multiple debridement, spinal cord decompression combined with anti-parasitic chemotherapy after surgery, are effective methods to delay or prevent the process of disease or recurrence. The recurrence of infection is common in most cases, and CT and MRI are the preferred methods of diagnosing this disease.

BACKGROUND: Hydatid cysts are parasitic zoonoses that often occur in the liver. Pancreatic hydatid cysts are very rare and are usually misdiagnosed as pancreatic cystadenomas. At present, surgical resection combined with albendazole administration is the standard treatment for pancreatic hydatid cysts. However, making accurate preoperative diagnoses and avoiding intraoperative cystic rupture are challenges for surgeons.
METHODS: A 28-year-old woman from the pastoral area presented to the surgical office complaining of abdominal pain and new-onset jaundice that began 9 days earlier. An enhanced computed tomography scan demonstrated a 6.0 × 5.3 cm pancreatic head cystic mass that compressed the common bile duct and induced choledochectasia. The preoperative diagnosis was pancreatic head cystadenoma, and laparotomic pancreaticoduodenectomy was initiated successfully. The intra- and postoperative diagnosis was pancreatic hydatid cyst. The patient was discharged uneventfully 7 days after the operation. A 1-year course of albendazole (15 mg/kg/day) was admitted.
CONCLUSIONS: Pancreatic hydatid cysts are rare and often misdiagnosed as other types of cysts. History of living in an area in which the causative organism is endemic and positive anti-echinococcus IgG antibody status could help with the diagnosis. Radical resection combined with oral albendazole administration is the standard treatment for pancreatic hydatid cysts. Avoiding perioperative cystic rupture and abdominal echinococcosis implantation metastasis is crucial for the success of the operation.

BACKGROUND: The present study was conducted in Jul 2019 and Jan 2020 in two wildlife parks of the Nowshera district, Khyber Pakhtunkhwa, Pakistan, where the endangered Punjab urial (Ovis vignei punjabiensis) is successfully bred in captivity. We determined diversity of internal and external parasites that take advantage of the situation of congestion, resulting in massive mortalities of wild animals in captivity.
METHODS: Internal parasites of living urial were determined by direct wet smear and flotation methods, while dead urial was necropsied for any pertaining observation.
RESULTS: All examined fecal samples were found infected with gastrointestinal parasites, which had significant difference in the total abundance in winter and summer. S. papillosus and H.contortus, and a single protozoan, Eimeria spp. were the dominant parasites in fecal samples. Ticks collected from urial enclosures and dead animals were of single species H. anatolicum. Theileria spp. was observed in blood, while hydatid cysts were found in lungs and liver of necropsied urial.
CONCLUSIONS: The study indicates that internal parasites such as Haemonchus contortus and Strongyloides papillosus, while external parasites as Hyalomma anatolicum ticks played major role in the population decline. Strict veterinary control of infectious diseases, provision of hygienic and supplementary diet, and proper maintenance of urial population are necessary measures for the control of mortalities.
