Hydatid disease of the spleen: imaging findings in nine patients

Splenic involvement is uncommon in patients with hydatid disease. The radiologic and clinical findings in nine patients with splenic hydatidosis are described. The three men and six women were 41-76 years old (mean, 58 years). Their histories and physical findings, the results of serologic tests for hydatidosis, and imaging procedures were evaluated. Plain abdominal radiographs were obtained in all nine patients, sonograms in six, and CT scans in seven. Plain films showed calcification of the cyst wall in four of the nine patients. On sonograms, five lesions were anechoic and one was echogenic. On CT scans, all lesions except one were of lower attenuation than the surrounding spleen. None of the lesions enhanced after administration of IV contrast material. Although rare, splenic hydatidosis should be included in the differential diagnosis when a cystic splenic lesion is identified with sonography or CT.     

Pulmonary hydatidosis. Contribution of x-ray computed tomography

33 patients with pulmonary hydatidosis were followed by CT scan imaging. 53 hydatid cysts were found in 31 of them. The remaining two were cases of metastatic hydatidosis, the primary affection was cardiac located with multiple small bilateral cysts. The observed cysts were single in 27 cases and multiple in 4, totalizing 26 cysts. Among the 27 single cysts, 15 were found to be complicated while 8 cysts were complicated among the four cases of multiple hydatidosis. This paper gives the most important signs observed by CT scan imaging in 33 cases examined during 6 months in the Central Service of Radiology Avicenne CHU, Rabat.     

Isolated hydatid disease of the spleen: CT findings in 4 patients and differential diagnosis

AIM: To report our experience with four cases of isolated hydatid disease of the spleen studied by spiral Computed Tomography (CT) and to review the literature with special attention to the differential diagnosis with other focal lesions of the spleen. MATERIALS AND METHODS: The spiral CT images and clinical records of four patients (1 man, 3 women; age range 26-45 yrs) affected by isolated hydatid disease of the spleen were retrospectively evaluated. None of the patients had a history of hydatid disease. All the patients were evaluated by plain and enhanced spiral CT of the abdomen. All patients underwent preoperative chest X-ray and surgery; all surgical specimens were studied by histology. RESULTS: Spiral CT depicted all the hydatid lesions of the spleen. It showed the location, size, low density of their content without enhancement after iv contrast medium injection, the possible presence of daughter cysts, the appearance of the wall with calcifications, and excluded the presence of complications. The preoperative chest X-ray was negative for focal pulmonary lesions in all cases. Pathology confirmed the diagnosis of hydatid disease in all cases. CONCLUSIONS: According to our results and to the literature, spiral CT plays an important role in the pre-surgical evaluation of patients with hydatid disease of the spleen, and provides useful information for differentiating the disease from other isolated cyst-like lesions of the spleen.

Vertebral and spinal cord hydatidosis. Contribution of radiology and x-ray computed tomography. Apropos of 36 cases

A study of 36 cases of vertebral and spinal cord hydatidosis seen between 1970 and 1984 allowed their division into three groups: those with purely intravertebral lesions, vertebral hydatid osteopathy, and hydatid pseudo-Pott's affections. The contribution of conventional radiology is reviewed at length and the importance of computed tomography emphasized for screening of extension and surveillance of "white cancer", a term applied by Deve to bone hydatidosis. Use of the scanner for CT imaging makes screening for residual or recurrent lesions a radiologic exploration.     

The role of computerized tomography in the diagnosis of hydatid disease]

The Echinococcus granulosus disease, or hydatidosis, is endemic in Italy; it has high incidence in Sardinia, Latium and Apulia. The CT findings were examined of 120 patients with hydatid cysts in the liver, lungs, kidney, spleen, peritoneal cavity, retroperitoneal space, and spine. The smallest cyst demonstrated by CT had diameter = 1 cm; CT was also more sensitive than conventional radiology and US in demonstrating unusual localizations of hydatid cysts. CT findings alone allowed a correct diagnosis of the nature of the cyst to be made in 61.5% of cases and, when combined with immunodiagnostic tests for hydatid disease, in 94.5% of patients. Moreover, CT is essential not only for a correct treatment planning, but also during follow-up.     

Hydatid cysts of the liver with concomitant massive peritoneal hydatidosis: a case report

The worldwide distribution of Echinococcus granulosus and its capability to persist in the human organism by causing serious medical and economical damage makes this parasite popular in terms of diagnosis and treatment implementation. Besides the liver as the primary target organ for this parasite, cases of secondary peritoneal hydatidosis are reported. Although rarely, they present with unusual abdominal symptoms with a bizarre presentation on abdominal ultrasound and Computerized Tomography scans. We present a case of a 44 years old male patient with concomitant presence of liver hydatid cysts and massive peritoneal hydatidosis treated with a combination of surgery and postoperative medications. The treatment of peritoneal hydatidosis consists of surgical removal of all the present cysts. In addition, anti-parasitic drugs are recommended to prevent a recurrence. The concomitant presence of liver hydatid cysts and peritoneal echinococcosis can appear as a result of abdominal trauma or iatrogenic spillage during abdominal surgery.     

肝包虫病的CT诊断

包虫病常在幼年感染，潜伏寄生，缓慢增长，无自觉症状，甚至发生合并症仍被误诊，引起严重后果，依靠一般诊断方法难以早期诊断。自应用ＣＴ扫描诊断方法，发现了各种类型肝包虫病的典型图像，不仅可经ＣＴ达早期诊断，而且可检测出各种合并症的特殊病理形态改变。本组作ＣＴ扫描检查２２５例，早期确诊率达１００％。
