Malignant Aspergillus flavus Otitis Externa with Jugular Thrombosis

We report a case of malignant otitis externa with jugular vein thrombosis caused by Aspergillus flavus. Magnetic resonance imaging revealed an unusual ink smudge pattern deep in a cervical abscess. The pattern was consistent with mycetoma and may be important for diagnosing these life-threatening infections

Abdominal wall morphometric variability based on computed tomography: Influence of age, gender, and body mass index

International audienceIntroduction: Ventral hernia surgery does not usually account for the individuality of the abdominal wall anatomy. This could be both because medical imaging is rarely performed before surgery and because data on abdominal wall variability are limited. The objective of the present study was to perform an exhaustive morphometric analysis of abdominal wall components based on computed tomography (CT) scans. Materials and Methods: A retrospective study was performed on 120 abdominopelvic CT scans of clinically normal adults aged 18-86 y equally divided between women and men and into four age groups. Each abdominal wall muscle was evaluated in terms of area, thickness, shape ratio, fat infiltration, and aponeuroses width. The influence of age, sex, and BMI was investigated, as well as muscular asymmetry. Results: The abdominal wall muscle area represented 8.5±2.5% of the abdominal area. The internal oblique muscle had the largest area, the rectus abdominis was the thickest, the transversus abdominis was the narrowest and had the smallest area. The width of the linea alba was 20.3±12.0 mm. The evolution of the abdominal wall with age was quantified, as well as the large differences between the sexes and BMI groups, resulting in strong correlations and highlighting the specific pattern of the transversus abdominis. The asymmetry of the left and right muscle areas oscillated around 17%. Conclusions: The various components of the abdominal wall have been precisely described. Knowledge of their variability could be used to develop the numerical modeling of the abdominal wall to ultimately improve surgical planning of ventral hernia surgery

Role of diffusion‐weighted imaging in the discrimination of purulent intrasinusal content: A retrospective study

International audienceOBJECTIVES:The objective of this study was to analyse MRI with morphological (T1, T2) and diffusion sequences (DWI, b1000) in patients presenting non-aggressive patterns of sinus opacity and operated on by functional endoscopic sinus surgery (FESS).DESIGN:A retrospective study.SETTING:Diffusion imaging in paranasal sinus pathology remains little known. To date, no imaging system is capable of determining the purulent content of a non-enhanced sinus filling.PARTICIPANTS:We included consecutive patients having undergone FESS in whom MRI of the paranasal sinuses was performed. Subjects were allocated to Case (pus) or Control (no pus) groups depending on sinus content found intraoperatively. FESS was performed for bacterial acute rhinosinusitis, acute exacerbations of chronic rhinosinusitis, non-purulent sinusitis, naso-sinusal polyposis, antrochoanal polyp, isolated polyp, angiomatous polyp and eosinophilic fungal sinusitis. Tumours, mucoceles and fungus balls were excluded.MAIN OUTCOME MEASURES:We analysed T1, T2, b1000 and MRI sequences and ADC map.RESULTS:On univariate analysis, intermediate signal in T2 and high signal in b1000 were associated with Cases (P brain was significantly associated with the case group. MRI with b1000_SI 1.450 × 10-3 mm2 /sec was significantly associated with the control group.CONCLUSIONS:Diffusion MRI offers extremely promising results regarding content characterisation of infectious sinus diseases

Report of the DEEP-REST stakeholder workshop, 11 May 2022

This report synthesizes the outcomes of the DEEP-REST stakeholder workshop held on May 11, 2022. The focus of the workshop was on the identification and prioritization of issues (political, economic, social, technological, environmental, legal) to be considered in conservation and restoration scenarios in a context of deep-sea mining. The report includes a copy of all the written material produced during the break-out group discussions. This report will serve as a basis for further discussion in the next steps of the stakeholder consultation process within DEEP-REST

Mucoceles of the anterior ventral surface of the tongue and the glands of Blandin-Nuhn: 5 cases

Introduction: Mucoceles are cystic diseases of the oral mucosa. The most common are ranula and mococeles of the lower lip. Blandin and Nuhn mucoceles, which develop at the ventral side of the tongue, are rare benign lesions. They are often misdiagnosed and sometimes confused with ranula. The recommended treatment is a complete surgical excision of the gland.Patients and methodsWe describe 5 clinical cases managed in service between 2009 and 2016. Clinical cases are presented in order to detail their clinical history, paraclinical and treatment.Results: The clinical appearance is a longitudinal swelling of the ventral surface of the tongue, parallel to the frenulum. The volume of the swelling is variable; it is normally around 30 × 10 mm. The paraclinical (ultrasound, CT, MRI, or ponction) could be performed. CT showed an cyst located on the ventral surface of the tongue, with liquid density. Blandin and Nunh mucocele were strictly anechogenic. MRI confirms the liquid content of this cyst (low T1signal, high T2signal and no post-contrast-enhanced). The resection of Blandin and Nuhn glands should respect the sublingual gland, the lingual nerve and the lingual veins in the mouth floor.Conclusion: This study demonstrates that Blandin and Nuhn mucoceles must be understood and recognised to propose complete excision of the Blandin and Nuhn gland and avoid recurrence
