A case study published in La Revue de Medecine Interne’s December 2019 issue has brought to light a rare and intriguing frontal sinus lesion that perplexed medical experts at the University Hospitals of Strasbourg. This article intends to dissect the findings of this case, to enhance the medical community’s understanding of such lesions and their impact on patients. We will reference five key scholarly sources, provide a detailed narrative of the case, and discuss the implications for future diagnostic and treatment approaches.

Abstract
In late 2019, a team of French medical professionals documented an unusual case of a frontal sinus lesion that manifested as diplopia in an elderly female patient. This case report analyzed diagnostic challenges and treatment decisions, contributing to the scarce literature on complex sinus pathology. Herein, we explore the significance of this report, emphasizing the medical and surgical intricacies.
Introduction
The frontal sinus, an intricate structure located within the depths of the forehead, plays a vital role in respiratory function and the overall health of the sinus cavities. However, when afflicted with pathologies such as mucoceles, these recesses can become sources of significant discomfort and severe medical conditions. In 2019, a case report detailed an exceptional encounter with a frontal sinus lesion, providing valuable insights for clinicians worldwide.
Case Presentation
The case concerned an aged female presenting to the emergency department at the University Hospitals of Strasbourg with diplopia – a condition where the patient experiences double vision. Upon examination, medical staff observed that the symptomatology was not isolated. The patient’s medical history, clinical evaluation, and state-of-the-art imaging techniques propelled the medical team towards a diagnosis that would affirm the complexity of sinus pathologies: a frontal sinus mucocele.
Diagnostic Approach
The investigation into the cause of diplopia necessitated a multi-disciplinary diagnostic approach. Initial clinical assessments leaned towards common etiologies such as vascular or neurological origins. However, advanced imaging technologies forthwith revealed a much rarer condition. Cross-sectional imaging, particularly computed tomography (CT) scans, showed a lesion indicative of a mucocele in the frontal sinus, emphasizing the significance of meticulous radiologic evaluation, especially in atypical presentations.
Discussion
On the Rarity of Frontal Sinus Mucoceles
Frontal sinus mucoceles are benign, cystic lesions resulting from the obstruction of sinus drainage. They may exert pressure on surrounding structures, potentially causing ophthalmological disturbances, as seen in this case. Mucoceles are reported to occur with relative infrequency, and their appearance in the frontal sinus is a rarity that often requires significant clinical acuity to diagnose.
The Emergence of Diplopia As a Symptom
Diplopia in this patient was an indirect result of the mucocele exerting pressure on the orbital contents, consequently impacting the alignment and function of the ocular muscles. The literature underscores the importance of considering sinus pathology as an etiological factor in unexplained cases of diplopia, particularly in the absence of more common causes (Patel, N. et al., 2017).
Advances in Imaging
Advanced imaging techniques are invaluable in diagnosing frontal sinus pathology. MRI and CT scans offer intricate details and a three-dimensional perspective, elucidating not only the presence of a mucocele but also its effects on adjacent anatomical structures (Lee, K.J., 2019). High-resolution imaging was crucial in enabling the medical team to visualize the lesion’s extent and consequent displacement of the patient’s eye structures.
Treatment and Management
The standard treatment for a frontal sinus mucocele involves surgical intervention, typically via endoscopic sinus surgery, to evacuate the cyst and restore proper sinus drainage (Sieskiewicz, A. et al., 2015). The interdisciplinary collaboration between emergency physicians, radiologists, and otolaryngologists ensures the optimal management of such complex cases.
Conclusion
Frontal sinus lesions, particularly mucoceles, demand a high index of suspicion and a comprehensive understanding of sinus anatomy and pathology. The 2019 case report not only adds depth to the medical literature but also underscores the necessity for vigilance in the face of uncommon presentations of symptoms like diplopia.
Contribution to Knowledge
Through detailed analysis of this case and its successful management, the report enriches the framework within which medical practitioners diagnose and treat complex sinus conditions, with a focus on thorough imaging and cross-disciplinary collaboration.
