Introduction: Abscess within a craniopharyngioma (CPG) is extremely rare and only 8 such cases have been reported in literature. Most patients present with hypopituitarism and visual disturbances. We report the first ever case of a CPG with abscess in a pediatric patient.
Case report: A 10-year-old girl presented with visual deterioration and bitemporal hemianopia. Her CT and MRI brain suggested of a sellar-suprasellar CPG. Due to ill-developed sino-nasal anatomy, a transcranial approach was made for the lesion. The lesion was well capsulated, thick walled, and appeared inflamed. Upon incising the wall, thick yellowish pus was drained out in a controlled manner. This was followed by a partial resection of the CPG wall and eccentric, adhered, calcified residue was left behind with an Ommaya drain. The abscess culture grew Enterococcus species and histopathology revealed adamantinomatous CPG. Patient underwent culture sensitive antibiotics course followed by radiation for the residue. She was doing well at 1-year follow-up with clinical and radiological improvement.
Conclusion: This is the first report of a pediatric case with secondary abscess in CPG. Operative management of such a case includes controlled drainage of pus without dissemination into the surrounding arachnoid space. The tumor and abscess have to be addressed as separate surgical entities; infection control and wherever complete resection is not feasible, partial safe resection followed by radiotherapy is a viable option.
