Guyon's canal syndrome resulting from an ulnar artery aneurysm: A case report.

INTRODUCTION AND IMPORTANCE: The ulnar's nerve compression at the Guyon's canal is not a frequent entity add to it that vascular lesions are rarely involved as a causative agent of this syndrome. CASE PRESENTATION: We report a case of a young male patient admitted in our department for a Guyon's canal syndrome due to an aneurysm of the ulnar artery and underwent a surgical decompression. Post-operative course was uneventful and the patient was satisfied with the result. CLINICAL DISCUSSION: Many etiologies are involved in the Guyon's canal syndrome and these etiologies can be arranged into groups. Previous treatment attempts, the duration and severity of the symptoms and the underlying etiology dictate the treatment options. Adjacent vascular enlargement is not a usual cause of Guyon's canal compression and a few case reports were reported in the literature. Surgical treatment by opening and releasing the roof of Guyon's canal and removing the aneurysm helped to achieve good outcome in most reports. CONCLUSION: Guyon's canal syndrome is less frequent than both cubital tunnel syndrome or carpal tunnel syndrome and many causative agents have been described. Vascular lesions are not the usual cause of compressing the ulnar nerve at the wrist and through this case we spotlighted this entity as another possible etiology requiring an adequate treatment for a better outcome.

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.
