A single worm-like structure in a urine collection bag: a case report.

BACKGROUND

The presence of a foreign body resembling a worm in a urine collection bag should lead to etiological investigation, as it may not be a parasite. It is thus important to consider the context and origin of the patient, together with the size, length, appearance, and characteristics of the suspected worm.

CASE PRESENTATION: The presence of an apparently mobile black filament resembling a worm was reported in the urine collection bag of a 77-year-old African male resident of our long-term care facility. We initially suspected a parasitic infection. The description of this foreign body suggested Dioctophyma renale (giant kidney worm); however, the analysis of the sample concluded that it was a blood clot. Its worm-like appearance was due to the tube-like nature of the urethra, causing the blood clot to be squeezed into a worm-like shape.

CONCLUSION

Such presentations can be misleading and may lead to unnecessary concern and investigations. A parasitological analysis can be essential for precise diagnosis.
