Purpose Several non-lacrimal lesions can present with lacrimal sac area swelling mimicking a dacryocystocele or mucocele with a possibility of misdiagnosis. This study investigates the clinic-radiologic characteristics of the mimicking conditions compared to true lacrimal sac distension. Design Retrospective, comparative, interventional case series Participants Patients referred by primary care ophthalmologists between January 2015 and October 2021 with a misdiagnosis of dacryocystocele or lacrimal sac mucocele (n = 39) and an age-matched group of proven true lacrimal sac swelling (TLS group, n = 44). Methods Data collected included demographics, presenting features, investigations, management, histopathology, and outcomes. Both groups were statistically compared for several clinical and radiological variables. Results Final diagnoses in the mimicking group were skin/subcutaneous swellings (14/39, 35.9%), vascular malformations (10/39, 25.6%), inferomedial anterior orbital cysts (7/39, 17.9%), sino-orbital masses (5/39, 12.8%). Female gender (<0.001), epiphora (p = 0.001), and discharge (p < 0.001) were significantly more frequent in the TLS group. The mimicking group was more likely to be associated with a longer swelling duration (p < 0.001), a swelling extending beyond the lacrimal sac area (p <0.001), orbital signs (p <0.001), and periorbital abnormality. Non-patent lacrimal irrigation (p < 0.001) was significantly more frequent in the TLS group. On imaging, all swellings in the mimicking group were separate from the lacrimal pathway and 94.9% (37/39) extended beyond the lacrimal sac fossa. Conclusion Various cutaneous, subcutaneous, vascular, inferomedial orbital cystic, and sinonasal pathologies can present with lacrimal sac area swelling and mimic a TLS. A high index of suspicion, a thorough clinical evaluation and proper imaging are essential to avoid a misdiagnosis.

Background: Masson's tumor (MT) is a rare benign vascular disease. In literature, detailed description of its radiological findings is not available and functional imaging such as diffusion weighted (DW)-MRI has never been described. We aim to summarize the CT and MRI findings in our representative case and to conduct a systematic review of the literature. Case Presentation: We reported a 54-year-old ex-smoker male patient who presented with a nodular mass to the left cheek. He denied any previous trauma. CT examination performed on initial presentation revealed a well circumscribed solid oval mass with soft tissue density, a calcified focus and no significative contrast enhancement after contrast administration. MRI showed a well circumscribed solid oval mass, with intermediate T2 signal intensity with areas of high T2 signal intensity and the presence of peripheral high-flow serpentine vessels, low T1 signal intensity. The mass showed a non-enhancing area with enhancing vessels after intravenous contrast administration. We surveyed CT and MRI findings of head and neck MT of English and French language papers, published from 1981 to 2019, together with our representative case. We included articles with a description of CT and/or MRI findings of head and neck MT. Conclusion:We have experienced one case and have evaluated imaging findings through systematic review. Only 36 articles were eligible. CT and MRI findings were reported in 27 and 23 articles, respectively. To date, no diffusion weighted imaging (DWI)-MRI findings have been described. The most frequent findings in CT were a well-defined mass with high or soft tissue density. The most frequent MRI findings were a non-homogeneous signal intensity in T1 and T2 weighted sequences, with foci of hyperintensity, multiple septations or flow voids. After contrast administration, the enhancement could be homogeneous, non-homogeneous, nodular or peripheral. In our case, we found a non-homogeneous hyperintensity in DWI-MRI with an area of restricted diffusion and low apparent diffusion coefficient (ADC) was observed (0.963 × 10 −3 mm 2 /s +\-0.12 SD). The imaging characteristics cannot provide a pre-operative identikit of MT and surgical removal is necessary to accurately differentiate it from malignant angiosarcoma but radiological evaluation is useful in surgical planning.
