A RARE CASE OF LATE-DIAGNOSED GIANT PRIMARY MULTIPLE ANGIOMA OF THE SMALL INTESTINE MESENTERY AND LIVER

Abstract

Background. Angiomas are benign neoplasms made up of blood and lymphatic vessels and are found in various organs. Lymphangiomas of the abdominal cavity most often occur in the mesentery of the small intestine and are more common in children. Large mesenteric lymphangiomas in adults are a very rare pathology. Objective. To present a rare case of late diagnosed giant cavernous cystic lymphangioma of the mesentery of the small intestine alongside with hepatic hemangioma in an elderly woman who did not seek medical care for a long time. Material and methods. The clinical manifestations, laboratory and instrumental findings, as well as autopsy of a patient died due to viral-bacterial pneumonia (SARS-CoV-2 + bacterial infection, unspecified) were analyzed. During the examination of the patient, a large abdominal tumor of unclear genesis and unspecified origin was detected. After the autopsy, a pathohistological examination of the detected neoplasms of the mesentery of the small intestine and liver was performed, which made it possible to establish the diagnosis. Results. As a result of the autopsy, it was established that the patient, in addition to viral-bacterial pneumonia, had a giant cavernous cystic lymphangioma of the small intestine alongside with a hemangioma of the liver. The mass of the mesenteric tumor was 9350 g, the tumor size was 32.5 × 35.0 × 28.0 cm. The size of the hemangioma of the right liver lobe was 5 × 4 × 4 cm. Conclusion. Tumor progression, increased intra-abdominal pressure, compression of abdominal organs, high diaphragm position, as well as other factors contributed to the development and severe course of viral-bacterial pneumonia. The immediate cause of death was intoxication and progressive pulmonary-cardiac insufficiency.
