Indian Journal of Pathology and Microbiology , 2009,
Abstract: Cystic hydatid disease may develop in almost any part of the body. Approximately 70% of the hydatid cysts are located in the liver followed by the lung (25%). The kidneys, spleen, mesentry, peritoneum, soft tissues and brain are uncommon locations for hydatid cysts. Renal involvement in echinococcosis is extremely rare. Hydatiduria accompanies only 10-20% of all cases of renal hydatidosis and is usually microscopic. Gross hydatiduria is an exceptional presentation of hydatidosis. We report an exceptionally rare case of multiple hydatidosis with cysts in the liver, spleen, kidney and peritoneal cavity, presenting with gross hydatiduria.
Hydatid Disease of the Femur with an Extraosseous Extent due to a Former Biopsy Complicated by a Pathological Fracture
M. Ciftdemir,A. Sezer,F. O. Puyan,C. Copuroglu,M. Ozcan
Case Reports in Orthopedics , 2012, DOI: 10.1155/2012/169545
Abstract: Hydatid disease of the bone represents about 1–2.5% of all human hydatid disease. Spine is the most affected part of the skeleton with 50% incidence of all bone hydatidosis. Extraspinal bone hydatidosis is much rare. Diagnosis is difficult in the bone hydatid disease. Bone tumors, tumor-like lesions, and specific and nonspecific infections should be considered in the differential diagnosis. Radiological, laboratory, and clinical findings combined with strong element of suspicion are the key for diagnosis. Bone biopsies should be avoided because of the danger of anaphylaxis, sensitization, and spread. This paper describes the management of a patient with primary hydatidosis of the femur, which had been complicated by an extraosseous involvement, cortical erosion, and a pathological fracture due to a former needle biopsy.

Introduction Hydatid disease caused by Echinococcus granulosus is a zoonosis which human beings occasionally become intermediate hosts. Hydatid cysts may develop anywhere in the body. It is mostly found in liver and lungs. The incidence of bone hydatidosis is about 1–2.5% of all human hydatid disease [1]. Spine is the most affected part of the skeleton with 50% incidence of all bone hydatidosis among humans. Primary bone hydatidosis develops when the scoleces are localized in the bone. Cysts within the bone may remain asymptomatic for years. Osseous tissue limits the expansion of hydatid cyst. In bone hydatidosis, daughter vesicles develop rather than a single cyst because of the dense and hard structure of the bone. Cysts spread slowly in medullary cavity eroding the bony trabeculae. Patients may complain of pain but often delay consulting a physician until neural compromise or pathologic fracture. This paper describes the management of a patient with primary hydatidosis of the femur, which had been complicated by an extraosseous involvement, cortical erosion, and a pathological fracture due to a former needle biopsy. 2. Case Report A 50-year-old man, labourer in textile industry, has been admitted to our clinic with pain and swelling in his left thigh. The patient had a needle biopsy 6 years ago in another hospital because of a suspicious lesion seen on plain radiographs. Histopathological result revealed a hydatid cyst of left femur. Surgical treatment was recommended at that time, but the patient did not accept the recommended surgery. The patient has been treated with albendazole and mebendazole in irregular and interchanging episodes for 6 years. In physical examination, a large, immobile, and painless mass found at the

Iranian Journal of Parasitology , 2007,
Abstract: Background: Hydatid disease is a major world health problem and pulmonary hydatidosis is a widespread disease. It is presented with different clinical manifestations. In order to determine the most clinical manifestation, diagnostic methods and clinical outcome in our patients, we conducted this study.Methods: Forty-nine patients with pulmonary hydatid cysts who were admitted to our hospital in Zahedan (Southeast of Iran) between 1990 and 2005, evaluated. We retrospectively reviewed the patients' symptomatology, diagnostic studies, treatment options, and morbidity as well as mortality rate. Results: The ages of the patients ranged from 16 to 68 years (mean 43 years). Seventy-five percent of patients were from male gender. Hemoptysis was one of the most common clinical presentations in our patients. Radiological studies were the main diagnostic tool. The correct preoperative diagnosis was made in 92% of the patients by chest roentgenogram plus chest CT-Scan. Eighty seven percent of patients were treated by surgical route. Only one patient was expired during surgery. Conclusion: Upon the results emerged from this study, hemoptysis is one of the most prevalent clinical manifestation in patients with pulmonary hydatidosis and it can mimic pulmonary tuberculosis in endemic area.

Abstract: In this study, we collected 100 samples of liver hydatid cyst and blood of infected sheep from the Ahvaz abattoir. The existing Ca, P, Mg, Na and K were measured by an auto analyzer apparatus. The result of T. student test showed that there are a significant difference between serum and fluid of cyst in all electrolytes (p<0.05). There was also a significant difference between these electrolytes in infected sheep and normal sheep (p<0.05). These results confirmed that the entrance of essential electrolytes have depended on selective permeability and parasite requirement. Ca and P have vital roles in the prevention of hydatid cyst fluid acidity. Understanding parasite nutrition behavior would help us to conduct a better drug treatment in inoperative cyst via selection of effective drug and adherence of this drug to biological material that promote distribution of drug to the cyst.

Journal of Neurological Sciences , 2012,
Abstract: Objective: Cerebral hydatid disease is a rare manifestation of echinococcosis but it constitutes a significant part of all intracranial mass lesions. This study aims to determine the clinical, radiological and surgical features of brain hydatidosis and share our experience.Method: Medical records of ten patients with cerebral hydatid disease were retrospectively reviewed. Clinical presentations, radiological examinations, treatment modalities and outcomes of the patients were analyzed.Results: All patients were admitted from the rural areas. Nine patients had E. Granulosus cyst and one patient had E. Multilocularis cyst. The cyst was solitary in nine patients and multiple in one. Multiple organ involvement was found in one patient. Cysts were located in the right cerebral hemisphere in five patients, left cerebral hemisphere in four patients and posterior fossa in one. All patients were treated surgically. Complications related to surgery were observed in four patient. All patients improved after the treatment. There were no recurrences or residual cysts among the patients.Conclusion: Hydatic disease should considered in the differential diagnosis of intracranial space occupying lesions in developing countries. Early diagnosis of cerebral hydatid cysts may prevent serious life-threatening complications of this disease. Outcome is favourable when the cyst is completely removed without rupture.

Abstract: Hydatidosis is a parasite disease (of the liver, lungs, kidneys, bones and other organs) caused by larva of cystic form (cysta hydatigena) of thedogechinococcus (T. echinococcus). Its knowledge is of special diagnostic and clinic importance. The paper gives a x-ray image of the liver hydatidosis (calcified hydatid cyst, hydatid cyst with cysts-sprouts of the first order) as well as that of the lungs (hydatid cyst with the Zhebe's sign, empty pericyst) and of the kidneys (calcified hydatid cyst). In the hydatidosis diagnostics, the x-ray diagnostics is a method of choice.

Iranian Journal of Radiology , 2003,
Abstract: Background; Hydatid disease primarily affects the liver and typically demonstrates characteristic imaging findings. Secondary involvement due to hematogenous dissemination may be seen in almost any locations, e.g., lung, kidney, spleen, bone and central nervous system (CNS). Objectives: To review the different aspects of hydatidosis of the CNS briefly and discuss the pathognomonic features and rare varieties of radiological findings useful in preoperative diagnosis of the disease in the human CNS. Material & Method; In a retrospective study, the records of almost 100 cases of CNS hydatidosis were analyzed. The available images were reviewed by independent observers, either a radiologist or a neurosurgeon, and reported separately. Results; In skull X-ray films, nonspecific changes denoted increased intracranial pressure, skull asymmetry and curvilinear calcification in rare instances. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated the round or oval, well-defined cystic mass with an attenuation or signal intensity similar to that of cerebrospinal fluid, with no associated perifocal edema, and no contrast enhancement as the pathognomonic findings of brain hydatidosis. Similar findings were detected in hydatid cysts involving the orbit, spinal column and spinal cord with some variations. Such findings as mild perifocal edema, nonhomogenous contrast enhancement, non-uniform shapes, calcification and multiplicity or septations have been the atypical radiological findings. Conclusion; In endemic areas, familiarity with typical and atypical radiological manifestations of hydatid disease of the CNS, will be helpful in making prompt and correct preoperative diagnosis leading to a better surgical outcome.

Abstract: Secondary peritoneal hydatidosis is caused by spontaneous or iatrogenic rupture of hepatic echinococcal cysts. We describe the case of a 65-year-old Tunisian male patient with previous history of liver hydatidosis who presented to our attention with subocclusive status. Imaging revealed a retrovesical hydatid cyst, adherent to the sigmoid colon. The treatment of choice was surgical removal of the cyst and the sigmoid colon. The patient is now being closely followed up.
