Coronary Neovascularity and Fistula Formation in Left Atrial Thrombosis

In mitral valve disease, mural thrombus in the left atrium is common, particulary in the atrial appendage in patients with atrial fibrillation. Occasionally, the angiographic sign of "neovascularity" and "fistula" in the region of the left atrial appendage during coronary arteriography has been reported to indicate the presence of thrombus in the left atrium, which might not even be revealed by transthoracic two-dimensional echocardiography. We observed coronary neovascularity and fistula formation in two pateints with mitral stenosis and these findings were due to organized mural thrombus that was adherent to the wall of the left atrial appendage. So we report 2 cases with brief review of literature.

Mitral Atresia Associated with Corrected Transposition of Great Arteries

A case of congenital absence of right atriovntricular (A-V) connection of heart is reported. Patient was 81 day old male infant with chief complaints of dyspnea and irritability. Clinical evaluation revealed increased pulmonary vascularity on chest x-ray, absence of right A-V connection, regurgitation of left A-V valve, right-sided ventricular hypoplasia and L-TGA. Clinical assessment of the case was tricupsid atresia with LTGA and mitral regurgitation. Pulmonary artery banlding and artial septectomy was performed. Parenteral alimentation through the femoral veins resulted in obstruction of IVC and subsequent multiorgan failure. The autopsy findings of the heart were corrected transposition of great arteries with associated anomallies of right-sided mitral atresia, Ebstein's malformation of left-sided tricuspid valve, ventricular septal defect, muscular hypertrophy of right-sided left ventricle with luminal obliteration. Long segment of IVC was completely occluded due to occlusive thrombi with fungal infection. Bilateral kidneys were infarcted and azygos vein was markedly engorged. Microscopic examination revealed candidal colonization in the inferior vena cava and septic embolzation in brain.

Intracranial granulocytic sarcoma (chloroma) in a nonleukemic patient

Chloroma is a granulocytic sarcoma with it's characteristic greenish color. Recently there is an increased number of cases that are apparently aleukemic when the tumor mass is first presented. Recently we experienced a case of granulocytic sarcoma with characteristic green color (chloroma), which showed no evidence of leukemia in the bone marrow and peripheral blood. This patient presented headache, and was diagnosed brain tumor on computed tomography. A left parietal cranietomy was done to remove a large central dome-like mass, 8 cm, involving the dura with a slightly dusky greenish solid appearance. Compact nests of moderately mature granulocytes and immature cells comprised the tumor. Histochemical and electron microscopic studies confirmed these tumor cells as myeloid cells in varying stages of maturation. Several days after the operation, left cervical lymph nodes became palpated, and the biopsied lymph nodes revealed same neoplastic cells seen in the skull. However, bone marrow aspiration, biopsy and peripheral blood smears did not show any evidence of leukemia.
