Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Example: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
Which is the apt title for the abstract? option1: Refibrillation managed by EMT-Ds option2: Maintenance of compliance in a small diameter arterial prosthesis.
Example solution: Refibrillation managed by EMT-Ds
Example explanation: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.

Problem: Abstract: Mucoceles of the sphenoid sinus are rare. Only occasional reports have appeared in the medical literature since they were first described by Berg in 1889. The sphenoid sinus lies deep within the skull at the crossroads of 13 sensitive structures. The presence of a sphenoid sinus mucocele may be accompanied by a wide variety of signs and symptoms depending upon which of these structures are involved. The majority of these lesions are initially misdiagnosed as malignancies leading to increased patient morbidity and possible mismanagement. We present two cases of sphenoid sinus mucoceles which presented with a variety of neurological signs and symptoms. The radiographic findings were felt to be consistent with skull base malignancies. The diagnosis was corrected only after surgical exploration of the sphenoid sinus revealed a mucocele.
Which is the apt title for the abstract? option1: Sphenoid sinus mucocele masquerading as a skull base malignancy. option2: Centrilobular lesions of the lung: demonstration by high-resolution CT and pathologic correlation.
Solution: Sphenoid sinus mucocele masquerading as a skull base malignancy.
