Strangulated obturator hernia: a case report with literature review
Obturator hernia is rare. It occurs when part of the pelvic contents protrude through the obturator foramen. It is a diagnostic challenge in the emergency department since the signs and symptoms are non-specific. It often occurs in elderly, emaciated and chronically ill women. The clinical picture include intestinal obstruction with abdominal pain, nausea and vomiting. The treatment is only surgical. Delayed diagnosis of this condition usually leads to a high mortality rate. We report the case of an 83-year-old woman with a strangulated obturator hernia. The hernia was discovered early by computed tomography and was treated by emergency laparotomy. We emphasize on the rule of CT scan to establishing a prompt preoperative diagnosis of an obturator hernia, appropriate planning of surgical intervention and thus optimizing the outcome
Orbital varix: rare cause of blepharospasm
Orbital varix (or varicose) is an exceptional pathology with poor clinical sign. The blepharospasm can be a revealing cause. The long-term risk is optic atrophy and blindness. Magnetic resonance imaging is the best diagnostic tools. The rise of lesion dimensions by Valsalva maneuvers and prone position is characteristic. We report the observation of a 42-year-old young man, consulting for a blepharospasm of the left eye evolving for two years. Imaging investigations made the diagnosis of orbital varicose
Splenogonadal Fusion Discovered by Testicular Torsion
Splenogonadal fusion, which is adherence of splenic tissue to gonads, is an uncommon congenital anomaly which mainly affects males. Herein, we report a case of splenogonadal fusion in a 20-month-old boy presenting with acute scrotal pain and inflammation. With the suspicion of left testicular torsion, an emergent left scrotal exploration was carried out. It revealed a necrotic left testicle along with a 360° rotation of the spermatic cord and three accessory structures in the lower pole of the testicle. Histology showed the presence of a splenic tissue. Splenogonadal fusion can present as an acute condition mimicking a testicular torsion. But, one should always bear in mind the possibility of this association. Splenogonadal fusion should be included in differential diagnosis of testicular mass to avoid unnecessary orchidectomy
New approach based on the combination of phase and orientation vector for the detection of wall motion abnormalities
International audienceObjective: The aim of this study is to propose a new approach based on the combination of local phase and orientation vector for the regional detection of cardiac wall motion. Materials and Methods : Cine-MRI images obtained in 20 patients were used to compute the proposed image. Two expert radiologists reviewed the cine-MRI images to define regional wall motion areas for each patient. Results : According to the results. The accuracy of the detection of wall motion abnormalities improved by adding the proposed images (from 79.5% to 86.4%) together with sensitivity (from 79.4 % to 87.3%) and specificity (from 74.3 % to 86.4%). Conclusion: The use of the proposed image based on local phase and orientation vector proved to be a promising technique for the detection of left ventricular wall motion abnormalities

SARS-CoV-2 diagnosis using medical imaging techniques and artificial intelligence: A review
International audienceObjective: SARS-CoV-2 is a worldwide health emergency with unrecognized clinical features. This paper aims to review the most recent medical Imaging techniques used for the diagnosis of SARS-CoV-2 and their potential contributions to attenuate the pandemic. Recent researches, including Artificial Intelligence tools, will be described. Methods We review the main clinical features of SARS-CoV-2 revealed by different medical imaging techniques. First, we present the clinical findings of each technique. Then, we describe several artificial intelligence approaches introduced for the SARS-CoV-2 diagnosis. Results CT is the most accurate diagnostic modality of SARS-CoV-2. Additionally, ground-glass opacities and consolidation are the most common signs of SARS-CoV-2 in CT images. However, other findings such as reticular pattern, and crazy paving could be observed. We also found that pleural effusion and pneumothorax features are less common in SARS-CoV-2. According to the literature, the B lines artifacts and pleural line irregularities are the common signs of SARS-CoV-2 in ultrasound images. We have also stated the different studies, focusing on artificial intelligence tools, to evaluate the SARS-CoV-2 severity. We found that most of the reported works based on deep learning focused on the detection of SARS-CoV-2 from medical images while the challenge for the radiologists is how to differentiate between SARS-CoV-2 and other viral infections with the same clinical features. Conclusion The identification of SARS-CoV-2 manifestations on medical images is a key step in radiological workflow for the diagnosis of the virus and could be useful for researchers working on computer-aided diagnosis of pulmonary infections
Temporal choroidal fissure cyst: a rare cause of temporal lobe epilepsy
Only a few cases of temporal choroidal fissure cyst are reported. We describe a new case of an 8 years old girl who manifested complex partial seizure. The diagnosis was made by magnetic resonance imagining (MRI). The signal intensity of the cyst was identical to the cerebrospinal fluid (CSF), and the underlying hippocampus was compressed by the cyst. The seizures were medically controlled. The value of MRI in the diagnosis and medical treatment will be discussed
Cervicofacial lymphatic malformations: diagnosis and management
Abstract Background Lymphatic malformations are rare benign tumors that result from congenital and acquired alterations of the lymphatic vessels. They occur most commonly on the head and neck region. The aim of this study is to describe clinical profiles of lymphatic malformations of the head and neck (LMHN) as well as to study therapeutic modalities through our series and review of the literature. Results This is a retrospective record-based descriptive study conducted in the ENT and the Radiology departments over a 17-year period. Our study included twelve patients, aged between 8âmonths and 52âyears. Two swellings were present at birth and had not been prenatally diagnosed in both cases. One patient was affected by TRISOMY 21. All patients consulted for a painless mass of the head or neck. Seven masses were located in the suprahyoid region and five in the infrahyoid region. Ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) were realized to establish the diagnosis and assess the extent of the lesions. Surgical excision was performed in 7 patients. It was complete in 6 patients. Five patients were treated with sclerotherapy. The sclerosing agents used were Aetoxisclerol 2%, hypertonic saline, and absolute alcohol. One patient had a reversible paresis of the left mental nerve after surgery. An excellent response to sclerotherapy with complete resolution was obtained in 3 cases with no recurrence of the disease. Conclusions Surgical excision has been the management option of choice for LMHN. The recent advances in sclerotherapy make it safe and effective as a primary treatment modality for these lesions
