Pediatric cardiac hydatid cysts: a diagnostic odyssey: a rare case report.

Introduction: Hydatidosis, caused by the Echinococcus tapeworm, typically manifests with hepatic and pulmonary symptoms, but cardiac involvement, especially in pediatric cases, poses a rare challenge. This overview emphasizes the diagnostic complexities and potential complications associated with this uncommon parasitic disease. Case presentation: A 4-year-old child was presented with epigastric pain after an abdominal impact trauma. Clinical examination revealed tachycardia, fever, and pericardial effusion with an intramyocardial cyst. Hydatid serology confirmed the diagnosis, and subsequent imaging ruled out additional localizations. Treatment involved albendazole, pericardial drainage, and cyst removal, resulting in a favorable outcome. Discussion: Cardiac hydatid cysts, comprising only 0.5--2% of visceral cases, often occur in underdeveloped regions. The authors' case, affecting the right ventricle in a pediatric patient, contributes to the understanding of varied presentations. Diagnosis relies on echocardiography, computed tomography scans, and MRI, with surgery being the mainstay treatment. Symptomatic cases demand prompt intervention due to potential complications. Conclusion: This case underscores the intricate diagnostic journey and management challenges posed by cardiac hydatid cysts, particularly in pediatric populations. Collaboration between medical disciplines is crucial for timely diagnosis and effective treatment, emphasizing the importance of ongoing research in endemic regions.

Unusual coexistence of restrictive heart disease and Kallmann syndrome: a case report.

BACKGROUND: Kallmann-Morsier syndrome is a rare disease characterized by the association of congenital gonadotropic deficiency and anosmia or hyposmia. The cardiac manifestations associated with this syndrome are little known. Through this case, we will characterize the cardiac involvement of this disease in the light of what is already described in the literature. CASE PRESENTATION: We report the case of a young patient who presented with a picture of cardiac decompensation revealing restrictive heart disease. In her exploration, she was found to have primary amenorrhea, leading to the diagnosis of Kallmann syndrome. Medical treatment was optimized for the management of her cardiac decompensation as well as hormonal replacement treatment for her delayed puberty and growth. CONCLUSIONS: Cardiac manifestations in Kallmann-Morsier syndrome are few reported in the literature, and restrictive heart disease is uncommon with no cases report till now. This association suggests a possible common genetic origin that should be explored in the future.
