ABSTRACT

Authors report 10 cases of intracranial inflammatory granulomatous lesions which were identified on CT scan and proven pathologically after surgical excision. They were composed of three cases of tuberculoma, three cases of degenerated cysticercus, two cases of healed abscess and two cases of non-specific inflammatory lesions. Most patients were children or young adults. Seizure was the most frequent presenting symptom. All cases had characteristic CT findings in common : a small nodular or ring-like lesion with strong enhancement surrounded by irregular-shaped low density area. Surgical exploration is of value in that specific diagnosis would not be possible with clinical and radiological findings only.

Key Words: CT scan; Granuloma; Seizure; Nodular or Ring-like Enhancement Biopsy
