Splenic Infarction in Acute Cytomegalovirus and Human Parvovirus Concomitant Infection

Splenic Infarction: A Rare Complication of Infectious Mononucleosis

Infectious mononucleosis (IM) is caused by Epstein-Barr virus (EBV), and the condition is characterized by sore throat, fever, lymphadenopathy, and atypical lymphocytosis. These infections are common in early childhood, with a second peak occurring in late adolescence. EBV is spread by contact with oral secretions. Most cases of IM are self-limited. However, there are associated complications, some of which can be serious and fatal. We report the case of a 20-year-old man with splenic infarction and exuberant peritonsillar abscess secondary to an EBV infection. This case highlights the importance of accurate diagnoses and frequent monitoring in IM patients, given the risk of airway obstruction.

An Overview of Cytomegalovirus Infection in Pregnancy

The objective of this review was to bring to attention cytomegalovirus (CMV) infection during pregnancy, taking into consideration all relevant aspects, such as maternal diagnosis, fetal infection and prevention, prenatal diagnosis, and postnatal prognosis. A literature review was performed regarding adult and congenital infection. General information regarding this viral infection and potential related medical conditions was provided, considering the issues of maternal infection during pregnancy, transmission to the fetus, and associated congenital infection management. Prenatal diagnosis includes maternal serum testing and the confirmation of the infection in amniotic fluid or fetal blood. Additionally, prenatal diagnosis requires imaging techniques, ultrasound, and complementary magnetic resonance to assess cortical and extracortical anomalies. Imaging findings can predict both fetal involvement and the postnatal prognosis of the newborn, but they are difficult to assess, even for highly trained physicians. In regard to fetal sequelae, the early diagnosis of a potential fetal infection is crucial, and methods to decrease fetal involvement should be considered. Postnatal evaluation is also important, because many newborns may be asymptomatic and clinical anomalies can be diagnosed when sequelae are permanent.

Complete splenic infarction in association with COVID-19

COVID-19 predominantly affects the respiratory system. As a novel disease, understanding of its management and complications continues to grow. Herein, we present a case of almost complete splenic infarction in a patient with COVID-19 pneumonia. This case highlights the need to maintain diagnostic vigilance whilst investigating secondary complications of COVID-19. It is also important to stress the high incidence of thromboembolic complications in patients with COVID-19, which may occur anywhere in the vasculature.

Cytomegalovirus-Associated Splenic Infarction in a Young Female Patient

Cytomegalovirus (CMV) infection generally causes asymptomatic infection in the majority of immunocompetent individuals. However, the presentation may be complicated by life-threatening conditions in immunocompromised patients. We report a case of a 23-year-old healthy Caucasian female with acute CMV infection and splenic infarction. Serological studies confirmed acute CMV infection, and echocardiography did not show any evidence of endocarditis or mural thrombosis. We did not consider antiviral and anticoagulation therapies due to the immunocompetent nature of the patient and since the condition was suspected to be a minor vessel disease likely triggered by CMV infection.

Infarto esplénico asociado a infección por citomegalovirus, primer reporte de caso en Colombia

Introducción: El infarto esplénico ocurre cuando la arteria esplénica o alguna de sus ramas quedan ocluidas, ya sea por émbolos distantes o por trombosis in situ. Dentro de la literatura mundial hay muy pocos casos documentados de infarto esplénico asociado a infección por Citomegalovirus, por lo que este podría considerarse el primero en Colombia. Presentación del Caso: Se trata de una paciente femenina de 53 años quien fue atendida en una institución de tercer nivel de la Ciudad de Bogotá, Colombia, por cuadro de dolor abdominal, a quien se le realizó una tomografía abdominal contrastada que demostró en el bazo una lesión hipodensa en cuña correspondiente con infarto esplénico por lo cual se realizaron estudios complementarios evidenciando como único dato positivo la positividad de la IgM para Citomegalovirus, descartándose eventos de h ipercoagulabilidad. Discusión: El infarto esplénico es una condición infrecuente que normalmente se presenta con síntomas variables e inespecíficos, dentro de las enfermedades infecciosas que corresponden con aproximadamente el 30% de los diagnósticos de Infarto esplénico, la infección por Citomegalovirus únicamente ha sido reportada en muy pocos casos. Se presenta el caso de una mujer joven con infarto esplénico como diagnóstico final de dolor abdominal en quien se descartaron causas de hipercoagulabilidad y se confirma la infección aguda por Citomegalovirus, lo cual se ha descrito muy poco en la literatura y puede considerarse el primer caso reportado en Colombia.
