Pterygopalatine fossa (PPF) abscess is an exceedingly rare occurrence. Typically, it has been reported in association with odontogenic infections or hematogenous dissemination. In this report, we present the first case of PPF abscess where no obvious underlying cause or primary infection was evident. The patient initially presented with a 2-week history of left ptosis and persistent headaches, which were subsequently accompanied by fever and limited mouth opening. Based on elevated inflammatory markers and imaging findings, the diagnosis of a PPF abscess was established. Successful treatment was achieved through surgical drainage using an external cervical approach. Cultures from the aspirated pus identified Streptococcus constellatus as the causative agent. This case highlights the importance of considering PPF abscess in patients presenting with ptosis as an initial symptom. When diagnosed, surgical drainage should be considered as a viable therapeutic option.
