Abstract Background Toxocariasis is a helminthic infection caused by a nematode that mainly affects populations in tropical and subtropical latitudes. Humans are potential paratenic hosts, and clinical disease occurs as a result of parasite migration through intestinal tissue. We present a clinical case of otorhinolaryngological affectation by Toxocara canis. Case presentation A 60-year-old male from Ecuador, resident in Spain for 5 years, evaluated in the emergency department for presenting headache, otorrhea and left ear pain. Computed tomography (CT) and magnetic resonance imaging (MRI) reported a large mass of the nasopharynx with infiltration of the skull base, intracranial extension and a lesion in the left pons without being able to exclude metastases. Two Functional Endoscopic Sinus Surgery (FESS) biopsies were negative for malignancy. Despite not meeting the diagnostic criteria established by the existing literature, the clinical and radiological presentation, the presence of risk factors, a positive serology for Toxocara canis (IgGELISA) and the absence of alternative diagnosis were considered sufficient criteria to establish toxocariasis with inflammatory lesions in the nasopharynx and pons as the most probable diagnosis. Treatment with albendazole (400 mg / 12 h) and corticosteroids (1 mg / kg for 5 days) was started and continued for one month. Post treatment negative serology, and MRI and CT post treatment controls were performed after one year, both showing a decrease in lesion of the clivus as well as the pons. Conclusions With the appropriate personal history, toxocariasis should be included in the differential diagnosis of infiltrating lesions of the skull base with a negative study of tumor histology. Albendazole treatment has been shown to control and cure the disease. |
