Hydatid cyst of the sacrum: A case report.

INTRODUCTION AND IMPORTANCE: Bone hydatidosis is a rare parasitic infection caused by Echinococcus granulosus, with a frequency of 1-2 %, it has a high morbidity and mortality rate due to its long clinical latency and lack of symptomatic specificity. This often leads to delayed diagnosis and discovery, usually at the stage of complications. CASE PRESENTATION: We present a case of sacral hydatidosis in a 71-year-old patient with no prior medical history. The symptomatology was a pelvic pain that had been ongoing for 5 months with constipation and difficulty with defecation. The clinical and radiological findings initially suggested a primary or metastatic malignant tumour. The biopsy revealed a multivesicular cystic lesion, indicating a hydatid cyst of the sacrum, confirmed later by anatomopathological examination. The lesion was almost completely removed, drainage was performed and the patient was put on anti-parasitic treatment. CLINICAL DISCUSSION: The clinical presentation of bone hydatidosis is poor and its course is insidious, which often leads to a delay in diagnosis. Medical imaging can provide a precise assessment of the lesion, allowing for extensive surgical resection to be planned. However, therapeutic methods and health education in endemic countries are still the best measures for limiting the considerable damage caused by this parasite. CONCLUSION: Hydatid osteopathy is a slow and progressive disease that can be difficult to diagnose early, which can compromise the quality of treatment. Therefore, it is important to focus on preventive measures to eradicate this parasitic infection.

Isolated anterior dislocation of the radial head (case report).

We report the case of an isolated post traumatic radial head dislocation in a 5 year old child. Clinical examination and the X ray results allow the diagnosis which can be unnoticed. The reduction by external maneuvers avoids the surgical treatment which remains the gold standard for chronic dislocation.

Bilateral acetabular fractures (case report).

INTRODUCTION AND IMPORTANCE: Bilateral acetabular fractures are very rare. They are usually seen in the context of multiple trauma patients. This type of fracture poses a problem and difficulty in therapeutic management, sometimes resulting in serious sequelae and significant morbidity. CASE PRESENTATION: We report a rare case of bilateral simultaneous acetabular fracture in an adult, forty-seven years old man due to a road accident. CLINICAL DISCUSSION: Bilateral acetabular fractures are very rare. While bilateral acetabular fracture most frequently occur due to automobile accidents, other mechanism can be responsible for this injury as well. Furthermore, bilateral acetabular fractures are frequently associated with other lesions of the surrounding bones or tissues. Surgery is the most suitable treatment in most cases. The development of osteoarthritis is the most common complication of acetabular fracture and is directly related to the post-operative reduction obtained. Heterotopic ossifications are a complication associated with acetabular fracture. In acetabular fracture, the primary objective of surgical treatment is anatomical reduction of the fracture that will determinate the future of hip. CONCLUSION: The treatment goal of acetabular fracture is anatomic or near anatomic reduction of the articular surface. The risk of osteonecrosis is mostly related to the initial injury and time to reduction.
