RESUMO
OBJECTIVE: This study endeavors to assess the clinical and radiologic findings of Ecchordosis physaliphora (EP) in patients under long-term observation at our clinic, as well as in cases reviewed from the existing literature. METHODS: In our study, we evaluated EP lesions in a total of 16 patients, who underwent follow-up and treatment in the neurosurgical unit. We conducted a retrospective review using magnetic resonance imaging (MRI) and computed tomography (CT) studies to confirm the diagnoses as EP. We conducted a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, encompassing a database search from inception to January 2024. We included confirmed cases of EP from both surgically and conservatively reported studies. RESULTS: Our study included a total of 16 patients, consisting of 9 (56.25%) men and 7 (43.75%) women, with an average age of 45±17.3 years. Among them, 7 (43.75%) patients presented with headaches, while 3 (18.75%) reported hearing loss. Incidental EP was detected in 6 (37.5%) patients in the study during imaging performed for different indications. The key radiological features of EP comprised hypointensity on T1, hyperintensity on T2, and an absence of MRI gadolinium enhancement. In one out of the sixteen cases, we employed an endoscopic endonasal approach for resection, and there was no recurrence observed over an average postoperative follow-up period of 24 months. Among the 15 patients, who underwent conservative follow-up, 12 (80%) had the classical Type B EP, one (10%) patient exhibited BNCT in the C2 vertebra, and another (10%) patient presented with a variant type EP. CONCLUSIONS: Utilizing a combination of imaging modalities, ensuring a clear radiological distinction between EP and chordoma, can offer substantial advantages in this context. Given that EP might be incidentally discovered, and non-resistant symptoms may resolve on their own, considering conservative treatment before surgery may be a viable option in all cases.
RESUMO
ABSTRACT: Fifty-two years, NID type-2 diabetic female was admitted with progressive headache, enlarging, pulsatile midline mass, dizziness, and numbness of extremities. Physical examination revealed only hypoesthesia in the upper left extremity C7-dermatome. Preoperative computed tomography revealed eroded parafalcian dural mass and caused a round 7 cm calvarial defect over the superior sagittal sinus (SSS) and another left parietal 1.2 cm satellite mass. Magnetic resonance imaging revealed an extra-axial, diffuse heterogeneous gadolinium-enhanced, well-circumscribed lesion invading the SSS and Trolard veins (bilaterally). Supratotal resection 1 cm from the tumor borders was performed, histopathology suggested papillary thyroid carcinoma follicular variant. The euthyroid patient underwent total thyroidectomy, and final pathology revealed invasive TFC. 5-year follow-up was uneventful without recurrence or new metastasis. Parafalcian meningioma classification was reviewed for the best surgical approach. The definitive diagnosis of meningioma should be established with histopathological analysis. TFC should be included in the differential diagnosis in cases of extra-axial tumors.
