Citing articles via Web of Science Telefaxapinillaroa hotmail. The great number of eosinophils observed suggested the presence of parasites. Despite all the diagnostic methods available nowadays, it is not always easy to determine the etiological diagnosis and thus empirical treatments directed against both bacteria and Entamoeba histolytica are usually prescribed with very variable length of hospital stay 1,2,11,16, Upon admittance she had febrile peaks of up to 38 o C, without tachycardia or tachypnea.

During a four-year period, cases of infectious liver abscess have been included in the study. The first step is the direct smear to investigate not only bacteria but also other possible etiological agents, such as in the case reported here.

The specific diagnosis of Ascaris in the liver is established by the observation of eggs on direct or histological examination. Eosinophilia in the liver tissue suggests, as possible diagnoses, a reaction to drugs mediated by an immediate hypersensitivity mechanism, an inflammatory granulomatous foreign body type reaction, a parasitic disease or eventually proximity to involvement by Hodgkin’s lymphoma.

Finally, it is important to remember that the immune response to Ascaris is mediated by both cellular and humoral immune mechanisms, through IgE and IgM 5, The first culture of this material showed abundant Gram-negative bacilli and scarce Gram positive cocci, with an intense leukocyte reaction. How to cite this article. Liver abscess; Ascaris ; Amebiasis; Diagnosis; Colombia. Human helminthiases are amongst the most prevalent parasitic infections, and of them infection by Ascaris lumbricoides is the most frequent.

Nowadays, the liver ultrasound is the best and most frequently employed method, because it is cheap, non-invasive, non-irradiating and very comfortable for the patient; also, it has the advantage over isotope methods that it clearly allows the differential diagnosis between solid and liquid content 6.

This sample was processed as a tissue sample, cellular debris, abundant eosinophils, Charcot-Leyden crystals and Ascaris lumbricoides eggs were observed.

Charcot—Leyden crystals are microscopic crystals found in people who have allergic diseases such as asthma or parasitic infections such lfyden parasitic pneumonia or ascariasis.

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Services on Demand Journal.


Another possibility is the production of a liver abscess when the adult parasite dies inside the liver, giving rise to a necrotic focus, which can become subsequently infected. When the female penetrates deeply into the bile ducts, it lays eggs, which are carried into the liver parenchyma, leading to the production of a foreign body granuloma, known as granulomatous cristaes.


Other rare form is hepatic nodules with marked infiltration of eosinophils such as reported in a case of a year old man who had eosinophilia, an elevated level lryden serum IgE, and anti-parasitic antibodies The diagnosis of liver abscess can be suspected clinically, but to confirm it and determine its etiology several kinds of exams are required, including chest X-ray, ultrasound study, immunodiagnostic tests, microbiological tests and direct examination.

Upon direct examination of the material obtained, eggs of Ascaris lumbricoides were letden together with abundant Charcot-Leyden crystals Fig. Glycemia and kidney function tests were within normal limits.

They are indicative of a disease involving eosinophilic inflammation or proliferation, such as is found in allergic reactions and parasitic infections like Entamoeba histolytica, Necator americanus, Ancylostoma duodenale etc.

Laboratory exams may reveal alteration of the liver function tests, leukocytosis with neutrophilia, and increase in the erythrocyte sedimentation rate. Pathology of infectious diseases. Zur Kenntnis des Asthma bronchiale.
