Transmesocolic hernia with sigmoid colon strangulation without surgical history...
Aparício, DJ; Leichsenring, C; Pignatelli, N; Germano, A; Ferreira, S; Nunes, VThe incidence of internal hernias is rare (0.2-0.9%). The prevalence of intestinal obstruction for an internal hernia is low (0.5-5%), however if strangulation is present the overall mortality is higher than 50%. There are multiple places where an internal hernia may be localized, with transmesenteric: transmesocolic (8%) and transomental (1-4%) as the rarest. We report a series of two cases (men with 40 years-...
Upper limb vascular mapping with Doppler ultrasound: Technique precision evalua...
Germano, A; Gomes, A; Martins, R; Sousa, M; Nunes, VIntroduction: Doppler ultrasound is recommended by international societies for preoperative vascular mapping in vascular access surgery. Literature is scarce regarding data on Doppler ultrasound-associated errors. Objectives: Our aim was to evaluate Doppler ultrasound precision for upper limb vascular mapping. Methods: Fifty-two adult healthy volunteers were evaluated for superficial vein diameter, brachial art...
Normal Ultrasound Anatomy and Common Anatomical Variants of the Thyroid Gland P...
Germano, A; Schmitt, W; Carvalho, M; Marques, RHigh-resolution ultrasound is considered the best imaging technique for evaluating the thyroid gland, as it is accessible, non-invasive, and highly sensitive concerning the detection and characterization of thyroid nodules. However, a background knowledge of the normal ultrasound anatomy of the thyroid gland, adjacent structures, and its anatomical variants is crucial to avoid misdiagnosis in daily practice. Th...
Massive pericardial effusion caused by hypothyroidism.
Schmitt, W; Roque, D; Germano, AAlthough mild pericardial effusion is a usual finding in patients with hypothyroidism, massive pericardial effusion or pericardial tamponade is rare and customarily related to severe hypothyroidism. The diagnosis of hypothyroidism should be considered in the differential of patients presenting with unexplained pericardial effusion, even when signs and symptoms of hypothyroidism are nonexistent.
Ultrasound requested by general practitioners or for symptoms unrelated to the ...
Germano, A; Schmitt, W; Almeida, P; Mateus-Marques, R; Leite, VBACKGROUND: A higher prevalence of thyroid nodules/carcinoma in females is well-known from the literature. The reasons for this difference are not fully explained. We intended to assess gender variation in the referral for ultrasound-guided fine needle aspiration (FNA) of thyroid nodules, to study reasons for gender referral differences, and to assess differences in nodules characteristics between genders. METH...
Killian-Jamieson diverticulum mimicking a suspicious thyroid lesion
Schmitt, W; Germano, AKillian-Jamieson diverticulum represents a rare form of esophageal diverticulum originating on the anterolateral wall of the cervical esophagus. Despite its rarity, it is crucial to recognize this entity, with such specific imaging findings, to avoid unnecessary invasive procedures such as fine-needle aspiration or even surgery.

Categorização TIRADS (Thyroid Imaging Reporting and Data System) e Bethesda de ...
Germano, A; Schmitt, W; Ribeiro, C; Simões, H; Gasparinho, G; Ferreira, M; Gomes, AIntrodução: As categorizações TIRADS (thyroid imaging reporting and data system) e Bethesda atribuem riscos de malignidade e propõem recomendações a seguir visando uniformizar a interpretação desses exames pelos radiologistas e anatomopatologistas e triar eficazmente nódulos da tiróide para cirurgia ou seguimento. O objectivo do estudo foi avaliar o risco de malignidade das categorias diagnósticas TIRADS e Beth...
