Patient: Female, 27Final Diagnosis: LV hemangiomaSymptoms: Palpitation • dyspnea • fatigueMedication: —Clinical Procedure: Posterior atriotomySpecialty: CardiologyObjective:Rare diseaseBackground:Cardiac tumors are quite rare, and differential diagnosis of them is challenging.Case Report:A young lady with a history of palpitations, dyspnea, and fatigue was proven by transthoracic echocardiography and cardiac magnetic resonance imaging to have a mobile left ventricular mass with rounded contour attached to the mid-part of the interventricular septum. The mass was approached via a posterior inter-atrial approach to avoid left ventriculotomy and provide adequate exposure to completely excise the tumor and control its pedicle with minimal cardiac trauma. Histological examination of the mass was diagnostic of capillary and sinusoidal hemangioma.Conclusions:Complete excision of cardiac hemangioma is recommended once it is diagnosed, for histopathologic diagnosis and because of the possibility of serious complications.

Patient: Male, 48Final Diagnosis: Spontaneous hemarthrosis of right kneeSymptoms: A rapidly growing knee swelling was “witnessed” associated with severe tenderness, hotness and profound agony but without color changeMedication: —Clinical Procedure: Suprapatellar arthrocentesis of the right knee jointSpecialty: CardiologyObjective:Unusual clinical courseBackground:Despite the widespread use of fibrinolytic therapy and the numerous reports on its bleeding complications, spontaneous hemarthrosis following fibrinolytic therapy is quite rare.Case Report:We describe in this report a patient with no previous history of articular disease who developed a spontaneous right knee bloody effusion following fibrinolytic therapy using rt-PA for acute ST-elevation myocardial infarction. Furthermore, we provide a review of all cases of spontaneous hemarthrosis documented so far in the literature.Conclusions:Several pre-existing joint diseases may predispose to hemarthrosis following fibrinolytic therapy, even in patients who deny previous or current articular disorders. Therefore, hemorrhage should be considered in the differential diagnosis of mono-arthritis following fibrinolytic therapy for STEMI.
