PARAGONIMIASIS: A CASE WITH METASTASIS TO THE BRAIN. SURGICAL REMOVAL

Cerebral paragonimiasis mimicking tuberculoma: First case report in India

An 8-year-old male child of Tuensang District, Nagaland, India, attended Civil Hospital, Tuensang, complaining of cough, fever, headache, and inability to move right arm since one month. On clinical suspicion of tubercular meningitis, anti-tubercular therapy was initiated and the patient was referred to the Naga Hospital Authority. A brain computed tomography scan revealed an isodense area with surrounding edema on the left parietal lobe, which was diagnosed as tuberculoma and the anti-tubercular therapy was continued. As there was no sign of clinical improvement on completion of the three-month-ATD regimen, the patient was investigated for paragonimiasis. Laboratory investigations revealed peripheral blood eosinophilia, raised ESR, Paragonimus egg-positive sputum, and positive Enzyme-linked immunosorbent assay (ELISA) and ID tests for paragonimiasis. The Bacillus Calmette-Guérin (BCG) test and Acid Fast Bacilli (AFB) sputum smears were negative. Chest roentgenogram showed no abnormal findings. A final diagnosis of pulmonary paragonimiasis associated with cerebral paragonimiasis was made. The patient responded to praziquantel therapy. Cerebral paragonimiasis is a serious extrapulmonary form of paragonimiasis, sometimes life-threatening, but curable with praziquantel. It should be included in the differential diagnosis of cerebral granulomatous and other space-occupying lesions.
