Objective: The purpose of this study is to analyze a series of patients with intradural extramedullary tumors (IDEM) and assess factors that may modify or determine the final long term outcome and management., Materials and Methods: Single Center, retrospective study of a series of surgical patients with IDEM lesions from our Institution operated between 2010 and 2021. Patients with less than 6 months of follow up were excluded. Several preoperative demographics, clinical, imaging and surgical features, as well as histopathology, recurrence and adjuvancy were assessed. Patients' final clinical outcome was categorized using the McCormick scale., Results: A total of 203 patients with a mean follow-up of 30.50 months (range 6-130) were included. 57.64% of the analyzed population was female and the mean age was 50.51 years. The most frequent location of the tumors was dorsal (34.98%) followed by the lumbar region (32.02%). Total resection was achieved in 84.24% of cases, and the most frequent histopathology was Schwannoma (36.45%), followed by Meningioma (30.05%). Pain was the most usual initial symptom (63.05%). In our analysis, functional outcome after surgery was associated with statistical significance with preoperative McCormick grade, tumor type, EOR and postoperative complications such as hematoma and sphincter involvement., Conclusion: The management of these lesions depends on many factors. It is worthy of mention that clinical presentation, EOR, histopathology and postoperative complications have shown significant prognostic value for the final outcome. Early treatment with the intention of achieving GTR when possible, using carefully tailored approaches, should be considered before the onset of significant symptoms., (Copyright © 2023.

Objective: To digitise our old archive and evaluate the efficiency of this task, both in medical and economic terms., Material and Methods: All slides and negatives (8254) archived in our clinic were collected, digitised with a 5-megapixel slide scanner. The images were taken from 1972 to 1999. Quality and utility of images were taken into account, as far as costs of the task (up to 2100 euros), all the work done by the same ophthalmologist., Results: Of those identifiable, 62% of the patients had already died. Only 1.5% were archived for use; 70 images for teaching reasons and 60 for medical reasons, being incorporated into the patient's history. About 210h were spent on scanning, identifying, checking and uploading images. 84% corresponded to retinal pathology, 4% to glaucomatous pathology, 3% to anterior segment pathology and the last 9% to learning material. The quality of most images is good, and, in some cases, were important for the correct diagnosis of the pathology. If only medical reasons are taken into account, the number of images uploaded is very low when working with archives older than 50 years., Conclusions: Although there was a low percentage of scanned images, the task was efficient because of a low cost. Images older than 50 years must be evaluated before scanning because of their low utility., (Copyright © 2022 Sociedad Española de Oftalmología. Published by Elsevier España, S.L.U.

Spontaneous intracranial hypotension is an increasingly recognized cause of atypical, secondary headaches. Nevertheless, its clinical and imaging spectrum is far from an exhaustive definition, ranging from straightforward cases with unambiguous findings and prompt response to treatment to more challenging ones, requiring advanced, more complex imaging and targeted therapies. We describe two unusual cases as a cue to draw a literature-based, practical approach to the management of the syndrome., (Copyright © 2018 Sociedad Española de Neurocirugía.

Objective: To analyze the imaging characteristics of histologically diagnosed metastases to the breast., Material and Methods: We selected patients histologically diagnosed with metastases to the breast in our diagnostic and interventional breast imaging unit between March 2010 and September 2018., Results: A total of 9 patients (all women; mean age, 60 y; age range, 28-89 y) were diagnosed with metastases to the breast. In 1 (11.11%) case, the primary disease was diagnosed from the breast lesion. The primary tumors were melanoma (n=5), neuroendocrine tumor (n=2, one from the small bowel and one from the cervix), lung adenocarcinoma (n=1), and ovarian cancer (n=1). The clinical and imaging manifestations depend on the type of dissemination of disease and can simulate benign and malignant primary breast lesions., Conclusion: There is no specific imaging pattern for metastases to the breast that would help to orient the diagnosis. It is important to consider this etiological possibility if the patient has a history of a primary tumor in another organ., (Copyright © 2019 SERAM. Publicado por Elsevier España, S.L.U.

Aim: To examine the value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for the detection of bone metastasis in breast cancer patients and assess whether whole body bone scan (BS) with (99m)Tc-methylene diphosphonate provides any additional information., Material and Methods: Study group comprised 150 patients, mean age 52 years (range 27-85) with breast cancer, suspected of having bone metastases. All patients had undergone both FDG-PET/CT and BS with or without single photon emission tomography/computed tomography (SPECT/CT) within a period of 6 weeks. The final diagnosis of bone metastasis was established by histopathological findings, additional imaging, or clinical follow-up longer than 10 months. Cancer antigen 15-3 (CA15-3) and carcinoembryogenic antigen (CEA) were measured in all patients., Results: Histologically 83%, 7% and 10% had infiltrating ductal, lobular and mixed carcinoma respectively. Confirmed bone metastases were present in 86 patients (57.3%) and absent in 64 (42.7%). Mean CA15-3 and CEA values in patients with bone metastases were 74.6ng/mL and 60.4U/mL respectively, compared to 21.3ng/mL and 3.2U/mL without metastases (p<0.001). The sensitivity of FDG-PET/CT for the detection of bone metastases was 97.6% compared to 89.5% with SPECT/CT. In 57 patients, FDG-PET/CT correctly identified additional pulmonary, hepatic, nodal and other soft tissue metastases, not detected by BS., Conclusion: Our findings suggest that FDG-PET/CT is superior to BS with or without SPECT/CT., (Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.
