1/8. Hydatid cyst of the sacrum. Report of a case.

    An unusual case of hydatid cyst of the sacrum revealed by low back pain and sciatica in a 16-year-old is reported. Computed tomography and a surgical biopsy provided the diagnosis. The outcome was favorable one year after mebendazole therapy initiation.

2/8. Sacral hydatid cysts: an uncommon cause of neurogenic bladder.

    Hydatid cysts of the sacrum are rare entities, characterized by chronicity without any clinical manifestation and are usually misdiagnosed in the early stage resulting in significant loss of bone and destruction of surrounding tissue. One should keep this possibility in mind in cases of early sphincteric involvement with minimal sensorimotor deficit in the lower limbs and bone destruction on radiography.

3/8. Primary hydatid disease of sacrum affecting the sacroiliac joint: a case report.

    STUDY DESIGN: A case report of hydatid disease of the spine. OBJECTIVE: To describe an unusual case of hydatid disease of the sacrum affecting the sacroiliac joint and to discuss imaging, differential diagnosis, and treatment. SUMMARY OF BACKGROUND DATA: Hydatidosis or echinococcosis affecting the spine is rare and has a characteristic geographic distribution. Signs of sacroiliac joint involvement and accompanying neurologic deficits cause difficulties in differential diagnosis of this rare condition. methods: A case of 38-year-old female patient with low back pain and sciatica was presented. RESULTS: Plain radiographs, computed tomography, and magnetic resonance imaging scans revealed destructive expansive lesion located on the right sacrum and extended through the right sacroiliac joint. Surgical enucleation of the cysts was performed together with mebendazole treatment and histopathologic examination confirmed hydatidosis. CONCLUSION: This unusual disease should be kept in mind in the differential diagnosis of sacroiliac pain and sciatica, especially in endemic areas.

4/8. Hydatid disease of the pelvis.

    The clinical and radiological features of five patients with hydatid cyst of the pelvis are presented. The cysts were found in the following sites: the broad ligament, the pararectal soft tissues, the greater omentum, the ala of the sacrum and in the retrovesical space. Hydatid disease should be considered in the differential diagnosis of unusual cystic swellings in the pelvis, particularly in patients who have lived in endemic areas.

5/8. The value of computed tomography in osseous hydatid disease (echinococcosis).

    The authors report three cases of osseous hydatid disease (echinococcosis) in which examination by computed tomography (CT) was found to be helpful in establishing the diagnosis. Recognition of this rare bone infection in orthodox radiographs is notoriously difficult, but is aided by knowledge of the patient having lived in an area in which the disease is endemic. In two instances, one involving the shoulder and the other the thoracic spine, radiological abnormalities had been attributed at first to tuberculosis. In the third case, in which a destructive lesion in the sacrum had been interpreted correctly, CT studies provided confirmation of a recurrence. CT has proved to be an effective and sensitive method of demonstrating these destructive lesions in bone, of determining their spread, and of establishing the presence of other hydatid cysts in adjacent soft tissues. This technique has been found to be of value in preoperative planning of the surgical approach to hydatid lesions of the skeleton.

6/8. Hydatid cyst of the lumbosacral spine with large pelvic mass.

    A rare case of hydatid cyst of the lumbosacral spine, causing extensive destruction of the sacrum and a large pelvis mass, is reported; a cutaneous fistula from the pelvic cavity to the posterior lumbar region was also present. The patient was studied by computerized tomography and operated on by combined anterior and posterior approach. The sacral localization of the spinal hydatidosis and its extension into the pelvic cavity are unusual. CT and MR allow a good definition of the bone destruction and the abdominal and pelvic extensions. Radical removal of spinal hydatid cysts may be rarely accomplished, because of the extensive bone invasion, and multiple recurrences, requiring repeating operations, occur in most cases.

7/8. Sacrococcygeal hydatid cyst: another entity in the differential diagnosis of sacrococcygeal chordoma. Case report.

    A case of hydatid disease of the sacrum with severe neurological symptoms, which was misdiagnosed preoperatively as a chordoma, is presented. The patient had significant improvement of the neurological symptoms after evacuation of the cyst. Sacral hydatid cysts must be considered in the differential diagnosis of sacrococcygeal chordoma.

8/8. Sacral hydatidosis: value of MRI in the diagnosis.

    We present a case of primary hydatid disease of the sacrum. The diagnosis was made on MR imaging obtained to evaluate the spine for recurrent disc disease. The patient had previously undergone laminectomy elsewhere for L4-5 radiculopathy. Ultrasound-guided aspiration and visualisation of scolices confirmed the diagnosis. No other site of involvement was found.
