Consecutive Bilateral Iliac Stress Fracture in an Adult Male Runner.

Iliac stress fractures (ISF) are uncommon in sports, particularly among runners, and are attributed to repetitive loading and other predisposing factors. ISF poses diagnostic challenges due to nonspecific symptoms and the limited sensitivity of conventional imaging procedures. The reported case is about a 51-year-old male marathon runner with consecutive bilateral ISF. Initial symptoms included mechanical pain in the right buttock, leading to a diagnosis confirmed via pelvic MRI. Conservative management with eight weeks rest from sport activity was indicated with symptom resolution and return to sport. However, 20 days after returning to sport, the patient developed left-sided symptoms post-resumption of running, with MRI confirming a new ISF. An additional eight weeks of rest was prescribed, allowing the patient to resume sport at preinjury levels. ISF should be considered in runners presenting with gluteal pain, emphasizing the importance of early diagnosis. MRI emerges as a valuable tool for accurate diagnosis, guiding appropriate management strategies. Conservative management focusing on rest is paramount for favorable outcomes and optimizing runners' health and performance.

Radiological predictive remission factors of pulmonary involvement in systemic sarcoidosis: a computed tomography scan study.

INTRODUCTION: As little is known about the prognostic value of CT scan findings at onset in patients presenting with sarcoidosis, we aimed to identify factors independently associated with radiological remission of pulmonary involvement in systemic sarcoidosis on CT scan findings. METHODS: We conducted a retrospective descriptive and analytic study of patients with a biopsy proven systemic sarcoidosis. We compared patients on radiological remission (group 1) to those on stabilization or progression (group 2). Multivariate analysis of variables significantly associated with radiological remission in univariate analysis was performed using binary logistic regression. RESULTS: Out of 65 records of systemic sarcoidosis, 43 were analyzed. 18.6% where male and 81.6% female with a sex-ratio of 0.22 and a mean age at diagnosis of 47.2 ±13.6 years. We found atypical lesions in CT scan findings in 16 patients (37.2%). Comparative pulmonary CT scan findings at admission and at 12 months follow-up revealed 13 patients (30.2%) in remission (group1) and 30 patients in radiological stabilization or progression (group 2). On multivariate analysis, lymphopenia, calcifications, and typical CT scan findings at presentation were predictive factors of remission of pulmonary involvement in systemic sarcoidosis (aOR=27.57; 95%IC=2.67-284.63; p=0.005) (aOR= 37.2; 95%IC= 2.08-663.89; p= 0.014) (aOR=47.1; 95%IC= 1.79-1238.7; p=0.021) respectively. CONCLUSION: In patients with systemic sarcoidosis with no lymphopenia at onset or calcifications or typical CT scan findings at presentation, we suggest a close follow-up as well as an intensive treatment.

A case report of abdominal wall hydatidosis: An uncommon location.

Liver hydatid cyst fistulized in the abdominal wall is rare. The clinical symptoms were often misleading. It often poses a problem of seat diagnosis rather than a problem of its hydatid nature despite the great contribution of modern imagery. We reported this uncommon case to highlight the difficulties of preoperative diagnosis and a better operative approach. 46-year-old men consulted for right flank pain. The clinical exam revealed a right flank subcutaneous mass. An abdominal CT scan showed multicystic lesions on the right flank. The MRI showed multiple cystic lesions on the right flank with several endophytic and exophytic daughter cysts. The patient was operated on. A wide excision was adopted to remove all the cystic lesions. The postoperative follow-up was uneventful. Abdominal subcutaneous hydatid cysts cause a diagnostic problem and the treatment is controversial. Surgery remains the only curative treatment. It avoids the risk of complications such the fistula, infection, and rupture.

Post-traumatic lateral abdominal wall hernia: a case report.

Traumatic abdominal wall hernia (TAWH) also known as blunt abdominal TAWH is uncommon. The clinical diagnosis is difficult. The authors present a case report of posthigh-energy abdominal blunt trauma causing a TAWH. Case presentation: A 36-year-women, with unremarkable past medical history, was presented to the Emergency Department after a stuck in high-speed two automobiles. She was hemodynamic, respiratory, and neurologically stable. The BMI was 36 kg/m². The abdomen was not distended with an ecchymotic lesion on the right flank. The thoracic abdominal and pelvic computed tomography (CT) scan revealed a rupture in the lateral abdominal wall muscles with a TAWH in the location of the skin ecchymoses. There was no visceral lesion or intraperitoneal fluid. A conservative treatment was indicated. The follow-up was uneventful, with hematoma resorption and no cellulitis or abscess. The patient was discharged after 1 week. An abdominal repair will be planned using a mesh. Clinical discussion: TAWH is a rare entity. The best imaging modality for diagnosis is the CT scan allowing classification of the hernia and a screen for other injuries. The presence of an isolated TAWH must lower the threshold to closely monitor or to operatively explore, given the high rate of false-negative findings at imaging features. Conclusion: TAWH should be suspected behind any blunt abdominal trauma with high energy. CT scan and ultrasound were helpful for diagnosis and the only curative treatment is surgery to avoid complications.

Large splenic epithelial cyst: A rare presentation.

INTRODUCTION AND IMPORTANCE: Splenic cysts are infrequent and most of them are related to parasitic diseases. Splenic epithelial cyst (SEC) is the most common type of primary non-parasitic splenic cysts. Its pathogenesis is not yet clear. Splenic cysts are usually asymptomatic and are detected incidentally during imaging exams or an exploratory laparotomy. CASE PRESENTATION: Our case is about a primary SEC discovered incidentally. An 18-year-old male patient without any personal and family medical history, presented with symptoms of upper urinary tract infection. Renal ultrasound was performed and found incidentally a solitary cystic lesion in the spleen. A laparoscopic partial splenectomy was made then. The specimen was sent for pathological examination and a diagnosis of primary (epidermoid) epithelial splenic cyst was given. CLINICAL DISCUSSION: SEC is a rare pathology that could mimic other splenic cysts like hydatid cyst. The preoperative diagnosis of SEC can be suspected by ultrasonography, computed tomography or magnetic resonance imaging. However, histopathological examination is mandatory to confirm the diagnosis. A wide range of differential diagnoses is considered when we suspect clinically SEC because of its lower incidence. CONCLUSION: Actually, spleen-preserving surgery with minimally invasive methods such as laparoscopy is the gold standard for the treatment of SEC despite the risk of recurrence encountered with these techniques. However, different surgical modalities are discussed depending on the size and the location of the cyst and the patient's age.

Chest CT-scan finding of asymptomatic COVID-19 pneumonia: a prospective 542 patients' single center study.

Since asymptomatic infections as "covert transmitter", and some patients can progress rapidly in the short term, it is essential to pay attention to the diagnosis and surveillance of asymptomatic patients with SARS-COV2 infection. CT scan has great value in screening and detecting patients with COVID-19 pneumonia, especially in the highly suspected or probable asymptomatic cases with negative RT-PCR for SARS-COV2. This study aimed to detect incidentally COVID-19 pneumonia on medical imaging for patients consulting for other reasons.

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.

A Case of Behçet Disease Myocarditis Documented Using Cardiac Magnetic Resonance Imaging.

Acute myocarditis is extremely rare in patients with Behçet disease. Here we report a case of a 32-year-old man with a history of oral ulcerations who was admitted for fever and chest pain. On examination, he had bipolar ulcers with pseudofolliculitis and a positive pathergy test. Electrocardiogram and transthoracic echocardiography were normal. Cardiac magnetic resonance imaging revealed left ventricular inferior and lateral wall late gadolinium enhancement. A diagnosis of acute myocarditis revealing Behçet disease was made, and the patient was treated with colchicine and pulses of methylprednisolone, and cyclophosphamide. A 7-month follow-up magnetic resonance image showed a substantial decrease in the late gadolinium enhancement area.

A Spatiotemporal exploration and 3D modeling of blood flow in healthy carotid artery bifurcation from two modalities: Ultrasound-Doppler and phase contrast MRI.

In the present study, we investigated the velocity profile over the carotid bifurcation in ten healthy volunteers by combining velocity measurements from two imaging modalities (PC-MRI and US-Doppler) and hemodynamic modeling in order to determine the optimal combination for the most realistic velocity estimation. The workflow includes data acquisition, velocity profile extraction at three sites (CCA, ECA and ICA), the arterial geometrical model reconstruction, a mesh generation and a rheological modeling. The results showed that US-Doppler measurements yielded higher velocity values as compared to PC-MRI (about 26% shift in CCA, 52% in ECA and 53% in ICA). This implies higher simulated velocities based on US-Doppler inlet as compared to simulated velocities based on PC-MRI inlet. Overall, PC-MRI inlet based simulations are closer to measurements than US-Doppler inlet based simulations. Moreover, the measured velocities showed that blood flow keeps a parabolic sectional profile distal from CCA, ECA and ICA, while being quite disturbed in the carotid sinus with a significant decrease in magnitude making this site very prone to atherosclerosis.

A giant aneurysm of the left anterior descending coronary artery in the setting of Behcet's disease.

Behcet's disease is a chronic inflammatory syndrome that can affect arteries and veins of all sizes and is an unusual cause of myocardial infarction. We report a case of a 42-year-old male with no cardiovascular risk factors who was referred to our department for a spontaneously resolving anterior ST-elevation myocardial infarction. Clinical and biological investigations revealed a high probability for Behcet's disease. The coronary angiogram showed severe left main artery stenosis with a huge coronary aneurysm of the proximal left anterior descending coronary artery, which was treated by aneurysm resection and coronary artery bypass grafting. Inflammatory arteritis should be considered in young patients with low cardiovascular risk presenting with acute coronary syndrome.

Case Report: Concomitant coronary stent and femoral artery thrombosis in the setting of heparin-induced thrombocytopenia.

Heparin induced thrombocytopenia (HIT) is a rare but potentially life threatening  adverse drug reaction. We report an unusual case of concomitant subacute coronary stent and femoral artery thrombosis secondary to HIT. In the current era of extensive growth of heparin use and percutaneous coronary interventions, it's important for clinicians to remember that such complication might occur and should be prevented.

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.

Inverted Takotsubo syndrome in Androctonus australis scorpion envenomation.

CONTEXT: The nature of scorpion-related cardiomyopathy is still a matter of debate where specific toxin-induced cardiomyopathy, ischemic, or catecholaminergic cardiomyopathy is advocated as well. We report two cases of Takotsubo syndrome following envenomation by Androctonus australis, bringing new evidence for the fundamental role of catecholamines in the pathogenesis of this cardiomyopathy. Case 1: A woman aged 36 presented with pulmonary edema and shock following scorpion envenomation. Echocardiography-Doppler showed a LVEF at 30%. Cardiac magnetic resonance (CMR) imaging showed a basal ballooning of the left and right ventricles suggestive of an inverted biventricular Takotsubo syndrome. A second CMR performed after recovery was normal. Case 2: A woman aged 45 was admitted for pulmonary edema and shock consecutive to scorpion envenomation. Echocardiography showed a LVEF at 35%. CMR showed a basal ballooning. The patient was discharged four days following admission with a normal LV function on repeat echocardiography examination. CONCLUSIONS: Cardiomyopathy in these cases, following scorpion envenomation by Androctonus australis, fulfills the criteria of Takotsubo syndrome. These observations contribute to our understanding of the mechanism, prognosis, and treatment of scorpion-related cardiomyopathy.

Priapism in the Newborn: Shall We Intervene?

Idiopathic neonatal priapism is rarely published. We report the case of a newborn presenting with priapism on the first day of life and reviewed the published data on the management and the follow up of this condition.

An unusual etiology of posttraumatic Collet-Sicard Syndrome: a case report.

Posttraumatic Unilateral paralysis of the last four cranial nerves (IX-XI), known as collet-Sicard syndrome, is rare following closed head injury. A 21-year-old man presented with slurred speech, hoarseness voice and difficulty swallowing his saliva following closed head trauma. The cranial nerve examination revealed left sided severe dysfunction of cranial nerves VII, IX, X, XI, and XII. A CT-Scan of the neck was performed demonstrating a fracture of the left styloid process at the base of the skull. The Magnetic Resonance Imaging showed unusually well seen lower cranial nerves due to nerve edema. The patient was managed conservatively with steroids and regular sessions of neuromuscular and orthophonic rehabilitation. The nutrition had to be administered by gastrostomy since he was unable to swallow. Six months after the injury a total neurological recovery was noted. We present the exceptional case of Collet-Sicard Syndrome caused by styloid process fracture.
