Intramyocardial hydatid cyst revealed with ischemic stroke due to left ventricular systolic dysfunction: A case report

Cardiac echinococcosis, although rare, presents a range of clinical manifestations depending on the cyst's location within the heart. These manifestations can range from asymptomatic conditions to serious complications such as arrhythmias, valvular dysfunction, cardiac tamponade, heart failure, shock, or even death. This case report describes the unusual presentation of a young man with an intramyocardial hydatid cyst, which was incidentally discovered following an ischemic stroke. Diagnostic evaluation included echocardiography, as well as chest and abdominal angiography via computed tomography (angio-CT). Surgical intervention was undertaken, involving cystectomy and the removal of the cyst contents. The patient's postoperative recovery was uneventful and favorable. This report emphasizes important diagnostic and management considerations specific to cardiac hydatid cysts and includes a review of the relevant literature to provide context and depth to our findings.

Using imaging to diagnose renal tumors beyond nephroblastoma

Wilm's tumor (WT) accounted for the vast majority of renal tumors in children (92%). However, there are many atypical or rare forms of kidney cancer, and it is certainly useful to have a diagnostic orientation in imaging to differentiate between the different diagnoses, guiding that way the therapeutic management. We report the cases of 3 patients who were initially diagnosed with nephroblastoma on the basis of radiological data (via PACS search), underwent pre-operative chemotherapy and then nephrectomy, and whose anatomopathological evidence came back in favor of benign renal tumors. Nephroblastoma is the most common renal tumor in children, but other benign tumors should not be neglected, radiological signs that may point to this entity should be taken into account, so that neoadjuvant chemotherapy with its enfeebling side effects can be avoided.

Cholecystitis-related cystic artery pseudoaneurysm: Case report

The pseudoaneurysms of the cystic artery (CAP) are very uncommon. They usually develop as a result of an acute cholecystitis or after a cholecystectomy. Among the complications, we can find hemorrhaging, biliary blockage, and haemobilia. Limited understanding of the illness makes managing specific cases difficult. We describe a case of a cystic artery pseudoaneurysm complicating an acute cholecystitis that was successfully treated by transcatheter arterial embolization.

Lipoma arborescens of the knee: A case report

Lipoma arborescens is a rare and benign intra-articular lesion characterized by a lipomatous proliferation of the synovial membrane, usually affects the knee joint. It presents as an unusual cause of intermittent knee pain and joint effusion. We report a case of lipoma arborescens of the knee in a 23-year-old man that initially resembled inflammatory arthropathy. The diagnosis of Lipoma arborescens was made by magnetic resonance imaging of the knee and confirmed histologically by synovectomy. The purpose of our case is to show the imaging features enabling early diagnosis and appropriate treatment.

Case report: Infectious cerebral vasculitis due to rickettsiosis

Rickettsiosis is a widespread infection throughout the world and in Africa, it covers a wide range of infectious diseases caused by Rickettsia species. Rickettsial infections, with the exception of Q fever, typically present with fever, rash, and vasculitis. The central nervous system (CNS) can be affected by all rickettsial diseases and is an important target for several of them. Clinical manifestations are suggestive of rickettsial infection, but serology and skin biopsy provide confirmation. Although the presence of abnormal neuroimaging is rare, its presence is associated with a worse clinical prognosis. Computed tomography (CT) and magnetic resonance imaging (MRI) scans mainly show signs of vasculitis, which may be reversible if appropriate treatment is initiated early in the course of the disease. We present here a case of infectious cerebral vasculitis due to rickettsiosis with some MRI features.

Benign and malignant prolapsed uterine tumors : 4 case reports of an extremely rare entities

Prolapsed uterine tumors within the cervix or vagina, are attached to the uterine cavity by a soft tissue stalk. Malignant tumors and leiomyoma are the first diagnostic considerations for a prolapsed uterine mass with a visible stalk at MRI. This article describes 4 cases of patients who presented with large, necrotic prolapsed uterine tumors that were surgically confirmed and were diagnosed prospectively on the basis of MRI findings. Imaging, particularly MRI, plays a crucial role in the management of patients with prolapsed pedunculated uterine tumors, especially for pre-operative localization and surgical treatment. The 4 patients underwent a total hysterectomy with a complete resection of the mass. The histopathological report confirmed in the first case the diagnosis of a uterine leiomyoma with aseptic necrobiosis, in the second and third cases a sarcoma, and in the fourth case a serous adenocarcinoma.

Crack lung with toxic cerebral vasculitis: Case report

Crack is the most potent form of cocaine. It directly affects lungs if inhaled and the damage may include barotrauma, acute pulmonary edema, alveolar hemorrhage, bronchiolitis obliterans with organizing pneumonia, or vasculitis. The diagnosis of cocaine-related lung damage is based on clinical symptoms and radiological findings. When young individuals develop respiratory symptoms, investigation into cocaine use is necessary. We report the case of a young man with a history of cocaine use who presented for respiratory and neurological symptoms revealing crack lung and toxic cerebral vasculitis.

Bilateral thalamic infarcts: Percheron territory

Blood supply to the human thalami is complex and multiple variants exist. The artery of Percheron is one of those variants and is characterized by a solitary arterial trunk that branches from one of the proximal segments of either posterior cerebral artery and sup- plies blood to the paramedian thalami. Its occlusion results in bilateral paramedian thalamic infarction sometimes extending to the midbrain. We report a case of bithalamic infarction secondary to occlusion of the artery of Percheron. We will illustrate the complex clinical symptomatology and underscore the role of imaging, especially MRI, for diagnosis.

Tuberculous empyema necessitans: Case report of a rare occurrence

Empyema necessitans is a rare condition where tuberculosis is the most common cause. It can be found in both immunocompromised and immunocompetent patients, especially in endemic areas. We report a case of a 29-year-old male from North Africa, with an enlarging mass on the right thoracic wall. Imaging, particularly CT showed a cystic lesion in the right chest wall communicating with homolateral pleural effusion, compatible with empyema necessitans. It also showed patterns of pulmonary tuberculosis in the right upper lung. Treatment of empyema necessitans is a combination of medical and surgicaltreatment. Our patient underwent a surgical treatment consisting of flattening of the empyema with a Gene X-pert study of the fluid and the shell, followed by an anti-TB treatment. Anatomopathology confirmed the diagnosis of caseo-follicular tuberculosis.

Mediastinal fibrosis as a late and fatal complication of treated tuberculosis mimicking a neoplastic process in a 34-year-old man

Fibrosing mediastinitis, also known as sclerosing mediastinitis, is an uncommon condition marked by abnormal proliferation of fibrous tissue in the mediastinum. This condition may accrue either as an idiopathic condition or as a complication of an underlying disease process. Its pathogenesis remains unknown. However, most reported cases are incriminating abnormal immune-mediated hypersensitivity responses to Histoplasma infection. Other rare causes include tuberculosis, blastomycosis, and an idiopathic form that may be associated with other miscellaneous conditions. CT and MR imaging play a vital role in the diagnosis and management of this disease. We present a rare case of fibrosing mediastinitis as a late complication of tuberculosis in a 34-year-old man with a prior history of mediastinal tuberculosis, mimicking initially a neoplastic mediastinal process. We will describe this clinical case in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Case report: The dot in circle sign: A pathognomonic MRI sign of Madura foot

Mycetoma or Madura's foot is a rare condition in Morocco. It is a chronic infection that affects deep subcutaneous tissues and may eventually spread to deep tissues, muscles, and bones. It is caused by fungi or bacteria and most often affects the foot. Biopsy and microbiological examination help to establish a definitive diagnosis, but may delay it. Imaging plays a crucial role in early diagnosis, particularly MRI findings that show a pathognomonic sign of mycetoma which is the dot-in-the-circle sign. Computed tomography provides a better analysis of bone changes than plain radiography. Treatment is very difficult, especially if the diagnosis is delayed, and may even lead to amputation. We present here a case of mycetoma of the foot with some MRI features.

Synchronous congenital malignant rhabdoid tumor of the orbit and cerebellar atypical teratoid/rhabdoid tumor: Case report

Malignant rhabdoid tumor is an uncommon pediatric tumor that often arises from the kidneys but can also develop in other soft tissues including the orbits, where it is known as atypical teratoid rhabdoid tumor. Orbital location is exceptional, with just a few reported cases. Imaging allows for an accurate diagnosis, but histological confirmation is required. The treatment is yet unclear but nearly often surgical, either with or without chemotherapy. In this report, we present a case of a neonate of 1-month-old with an orbital primary malignant rhabdoid tumor with synchronous cerebellar location. The patient was unable to undergo surgery, he had chemotherapy, and unfortunately died 1 week after following palliative treatment. We will illustrate this clinical experience and point out the importance of radiological imaging in the assessment of this uncommon condition.

A case of ovarian endometrial stromal sarcoma: Radiological and histopathological findings

Endometrial stromal sarcoma (ESS) is an uncommon uterine mesenchymal neoplasm. The primary extra-uterine location of ESS is a very rare occurrence. We present a case of a 39-year-old woman presented with severe abdominal pain, MRI showed bilateral ovarian tumors with heterogeneous intensity on T2-weighted imaging (T2WI) and T1-weighted imaging (T1WI), with restricted diffusion, including hyperintense areas on T1WI, not erased on T1-weighted fat-suppressed imaging, hypointense on T2WI, and not enhanced after contrast. This mass extended to the Douglas and invaded the uterine and the rectum serosa suggesting an underlying endometriosis. No abnormalities were suspected in the endometrium. The exploration revealed a friable mass arising from ovaries associated with nodules in the small intestine and sigmoid. The patient underwent bilateral adnexectomy and the anatomopathological study revealed a low-grade endometrial stromal sarcoma. This is one of the few reports covering the radiological features of low-grade extra-uterine ESS in the ovary which is probably secondary to degeneration of endometriosis with no evidence of primary uterine ESS.

Neglected trauma-induced testicular torsion: Clinical, sonographic, and surgical correlation in a 13-year-old adolescent

Post-traumatic testicular torsion is a rare condition, accounting for approximately 4%-8% of all reported cases of testicular torsion in the literature. Prompt clinical suspicion and intervention are crucial; as testicular torsion is considered a medical and surgical emergency that may lead to testicular necrosis. Ultrasound imaging plays an important role in assessing the integrity of the traumatized scrotum and facilitating early detection of associated testicular torsion. In this case report, we present a neglected post-traumatic testicular torsion in a 13-year-old child that led to orchiectomy.

Unusual intracystic papilloma arising from ectopic axillary breast tissue: Case report

Accessory breast tissue (supernumerary breast tissue) is due to the absence of regression of the primitive milk lines during embryonic life which extends from the axilla to the groin. It is mostly located in the axilla where it is often confused with the axillary extension of the breast, or any pathological process occurring in armpits. Ectopic mammary glands should not be misdiagnosed as it can potentially undergo the same pathological processes that occur in a normally located breast including benign or malignant breast tumors. We report the case of an intracystic papilloma arising from left axillary accessory breast tissue in a 63-year-old woman. The principal symptom was pain in a palpable left axillary mass without inflammatory signs. Subsequent imaging and histopathologic examination proved it to be a papillary tumor in ectopic breast tissue.

Incidental finding of undiagnosed aortic coarctation in an elderly patient with a rare association with thymic carcinoma: a case report with review of the literature

Aortic coarctation is a congenital malformation that is relatively prevalent, occurring in approximately 5 out of every 1000 births. The narrowing typically happens at the aortic isthmus between the left subclavian artery and the arterial ligament. It is frequently associated with a bicuspid aortic valve. Generally, coarctation of the aorta is identified and treated during childhood or early adulthood. If left untreated, this condition can lead to a reduced life expectancy in individuals who have not received treatment. We present a case of a 52-year-old man who complained of chest pain, sputum, and hemoptysis persisting for approximately 2 years. Contrast-enhanced computed tomography (CT) scans revealed the presence of an anterior mediastinal mass, which was later confirmed to be a thymic carcinoma (on histological study). Additionally, an incidental finding of a thoracic aortic coarctation with a well-developed collateral circulation was observed. The discovery of aortic coarctation in adult patients as an incidental finding is rare and particularly uncommon in association with mediastinal or thoracic tumor pathology. Adult and elderly patients with uncorrected coarctation generally have a low survival rate, and the management strategies for such cases are controversial, especially when it is associated to other pathologies. Due to the complexity of therapeutic management and the limited literature available on postsurgical outcomes in these cases, making therapeutic decisions requires a multidisciplinary approach and personalized consideration for each individual case. This approach is necessary to evaluate the risk-benefit ratio and determine the most suitable therapeutic solution.

Diagnosis and treatment of mycotic aneurysms secondary to cardiac hydatid cyst: An unusual cause of multiple cerebral strokes in a 23-year-old female

Mycotic aneurysms (MA) are a rare but severe complication of systemic infections, carrying a high risk of rupture, hemorrhage, sepsis, and potential multiple organ failure. Intracranial arteries are often affected and present a significant mortality risk due to cerebral bleeding and ischemic strokes. In this paper we describe the case of a 23-year-old female patient who presented with a sudden onset of right hemiparesis, followed by loss of consciousness. Cerebral imaging revealed multiple infarcts in both hemispheres and intracranial hemorrhage secondary to ruptured pseudoaneurysms. On transthoracic echocardiogram, she was found to have a left ventricular cardiac cyst with mobile vegetations potentially responsible for mycotic aneurysms and cerebral strokes. The patient underwent endovascular embolization for the mycotic aneurysms and cardiac surgery for the left ventricular cyst with satisfying clinical outcomes. Postsurgical analysis revealed the cyst to be of hydatid (Echinococcus) origin.

Hydrosalpinx with adnexal torsion in an adult patient-A case report

Adnexal torsion is a common gynecological emergency and a significant cause of acute pelvic pain in women. Hydrosalpinx-induced torsion of the adnexa is a rare situation and requires prompt and accurate management. Twenty-three years old nulliparous woman admitted in our structure for acute pelvic pain. The ultrasound revealed an enlarged right ovary with an adnexal cystic mass. We suspected the diagnosis of a right adnexal torsion due to cystic ovarian mass. Laparotomy revealed torsion of the right adnexa and a second large mass appearing to be a hydrosalpinx. Diagnosis of adnexal torsion is difficult and is based on a range of arguments obtained by anamnesis, clinical examination, ultrasonography and other investigations. Early diagnosis is important for preserving tubal and ovarian function, given the risk of ovarian necrosis in young women. Laparoscopy is the gold standard for diagnosing and treating adnexal torsion. The treatment can be conservative or radical, consisting of detorsion of the twisted adnexa, with or without adnexectomy.

Hydatid pulmonary embolism underlying cardiac hydatid cysts - A case report

Cystic hydatidosis is an endemic parasitic disease with usual localization in liver and lungs. Rarely it localizes in uncommon sites, the right ventricle being an exceptional localization. We present an extremely rare case of a young man with hydatid pulmonary embolism complicating right-ventricle hydatid cysts. Echocardiography, CT pulmonary angiogram and MR-angiography were performed for the diagnostic evaluation. Our patient did not undergo surgery. He was discharged on a regimen of albendazole, and is still being followed-up. Hydatid disease rarely presents with pulmonary embolism. It has uncharacteristic clinical features, requiring particular diagnosis and therapy.

Budd-Chiari syndrome secondary to retro-hepatic vena cava web: An unusual cause of epigastric pain

Epigastric abdominal pain is a common indication for consultation. In the majority of cases, medical history, clinical examination and routine biological exams allow for an easy diagnosis. Sometimes the symptomatology is unusual, in which case it is essential to perform a complete clinical examination and to use various imaging techniques to search for eventual atypical causes. Membranous obstruction of inferior vena cava is a rare cause of such a phenomenon. We describe a Budd-Chiari syndrome caused by membranous obstruction of inferior vena cava in a 66-year-old woman with no medical history as a rare cause of epigastric abdominal pain. We will describe this clinical experience in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Lumbar puncture as a cause of tension pneumocephalus, pneumorrachis, and sacral meningocele infection leading to death: An extremely rare case report

Although it was first described over 100 years ago, lumbar puncture is still an important diagnostic tool for a variety of infectious and noninfectious neurologic conditions. With the widespread use of this common and relatively safe performed medical procedure, minor and major complications can occur even when standard infection control measures and good techniques are used, including post lumbar puncture headaches, infection, bleeding, cerebral herniation, radicular pain, and even pneumocephalus in extremely rare cases. We describe a previously unreported complication of lumbar puncture performed for the diagnosis of meningitis in a 33-year-old woman with no medical history causing pneumorrachis, tension pneumocephalus, and sacral meningocele infection leading to death. Lumbar puncture is a simple diagnostic procedure with few complications, but if the technique is incorrectly performed, or if it is accompanied by occult congenital malformations such as sacral anterior meningocele in our case, the consequences can be fatal.

A rare case of sphenoid giant cell tumor: Case report & review of imaging features post short-term denosumab treatment

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

Small bowel carcinoid tumor causing intestinal ischemia: A case report with review of the literature

Background: Intestinal carcinoid tumors are well-differentiated neuroendocrine tumors that are capable of secreting bioactive hormones and/or amines; These tumors are uncommon but are the most common primary tumors of the small intestine. Case presentation: We report the case of an 80-year-old woman who presented with a long history (about 14 years ago) of atypical digestive symptoms such as vague abdominal pain, alternating diarrhea, and constipation, treated as functional colopathy without improvement, until the day when she presented with worsening pain that prompted her consultation. CT scan revealed typical manifestations of a carcinoid tumor associated with signs of subacute small bowel ischemia. Despite the surgery being considered a gold standard treatment, it was rejected due to the extent of tumor mesenteric involvement, therefore, the patient received only somatostatin treatment. Conclusion: Small bowel carcinoid tumors are rare, with typical imaging features based on cross-sectional imaging (CE CT/MRI). Intestinal ischemia is a well-known complication that can be a factor in mortality.

Recurrent stroke in young adults caused by atypical fibromuscular carotid dysplasia

Background

Carotid Web and focal carotid diaphragm are atypical fibromuscular dysplasia. The bilateral stroke due to this dysplasia is extremely rare. We will report a series of three young patients, admitted for a bilateral ischemic stroke caused by carotid bulb web and internal carotid diaphragm. Also, we will discuss their manifestations and treatment modalities.

Case presentations

In our study, we will report a series of three North African patients, two females an one male, at the mean age of 37, admitted for an ischemic stroke caused by bilateral carotid bulb web and bilateral internal carotid diaphragm.All of our patients were young and didn't have a history of drug use.

Conclusions

In our series, only end-vascular treatment was performed which was necessary to prevent any recurrence. Antiplatelet therapy was used in all cases to prevent any stroke during the follow-up.

Sigmoid lipoma as an exceptional cause of intussusception and bowel obstruction in adults: A case report and review of literature

Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.

Posterior mediastinal teratoma presenting as an abdominal mass in a child: A case report

We report the case of a 2.5-year-old child admitted for abdominal distension, whose imaging revealed a large posterior mediastinal cystic mass, with a tissue component, a calcification, and a minimal fat component. The ultrasound- guided biopsy led to the diagnosis of a benign extragonadal germ cell tumor, also called mature teratoma or dermoid cyst, whose mediastinal localization is rare, often localized in the anterior mediastinum, and rarely in the posterior mediastinum. The mainstay of treatment is complete surgical excision.

Intracranial bifocal germinoma

Primary intracranial germ cell tumors are rare, often affecting children and young patients. Germinomas are the most common type of germ cell tumors. We present the case of a 10-year-old child, who was admitted with decreased visual acuity, asthenia, polyuro-polydipsic syndrome, and gait disorder. His biological assessment showed an hypocortisolemia and diabetes insipidus. Imaging found a bifocal process in the suprasellar and pineal region, suggestive of a bifocal germinoma. Imaging data and the positivity of human chorionic gonadotrophin in the cerebrospinal fluid were in favor of the diagnosis of bifocal germinal tumor confirmed by biopsy. Currently the patient is hospitalized in pediatric oncology department.

The diagnosis of germ cell tumors is based on imaging, tumor marker assays, and biopsy. They are treated by radiation therapy alone or in combination with reduction chemotherapy, and surgery for tumor residues. The location of the tumor usually makes surgery difficult.

Hemimelic epiphyseal dysplasia: a case report

Hemimelic epiphyseal dysplasia HED also known as Trevor's disease is a rare pathology, characterized by a developmental disorder of an internal or external half of one or more epiphyses of a limb, mainly the lower limb, and/or of the short tarsal bones in children and young adolescents, with a male predominance. Its etiology remains unclear. Its clinical symptomatology is variable, ranging from asymptomatic involvement to orthopedic complications such as limb length inequality. As the clinic is non-specific, radiological assessment is the essential diagnostic tool for Trevor's disease, including standard radiography, MRI, CT, and possibly biopsy in some cases. The radio clinical signs make it possible to establish the diagnosis, even if it remains difficult because of the rarity of the disease and the presence of multiple differential diagnoses which are often better known such as osteochondroma and exostosis. After diagnostic confirmation, the therapeutic decision remains debated, ranging from simple observation to surgical excision. The prognosis of HED remains good, given the absence of the risk of malignant transformation. Post-therapeutic complications are dominated by recurrence or the appearance of secondary osteoarthritis. Objective: This clinical case challenges us to keep in mind the hemimelic epiphyseal dysplasia (HED) in front of a mass that originates at the level of the internal or external half of one or more epiphyses in children.

Pleural thymoma: A rare cause of pleural mass. About one case

Thymoma is a rare tumor arising from the epithelium of the thymus gland and is usually located in the anterior mediastinum. Ectopic thymoma is very rare and can be located in the neck, trachea, lung, and pleura. Through this manuscript, we report a rare case of a 50-year-old woman presenting with dyspnea and recurrent pleural effusion. Her computed tomography of the thorax showed a unilateral left pleural mass. Biopsy of the pleural mass confirmed the diagnosis of pleural thymoma and she was started on chemotherapy. To our knowledge, this is the first reported pleural thymoma in our region.

Unusual cause of binocular diplopia: Cavernous sinus hemangioma

Cavernous hemangiomas are rare account representing 5%-13% of the intracranial vascular malformations and occur in approximately 0.5%-1% of the population. We report the case of 34-years-old woman, having a medical history of seizure, admitted for headache with binocular diplopia. The radiology investigation and operatory piece has shown an association of cavernous sinus hemangioma and frontal focal cortical dysplasia. This study highlights clinical, radiological and therapeutic features of this entity.

Mediastinal bronchial artery aneurysm presenting as an incidental mediastinal mass: A rare finding

Mediastinal bronchial artery aneurysm is very rare and only few cases have been reported in the literature. The clinical presentations are varied, ranging from an incidental radiological finding to a cataclysmic rupture leading to hemorrhagic shock. Thus, a quick treatment is indicated upon diagnosis. Therapeutic options are various including surgical resection, stent grafting with percutaneous embolization of feeding vessel or transtarterial embolization. Herein we describe a case of an incidental mediastinal bronchial artery aneurysm in a 63-year-old man, managed by transtarterial embolization.

A case of a giant left ventricular pseudoaneurysm

A Left ventricular pseudoaneurysm is an outpouching resulting from myocardial free wall rupture which is contained by an adherent pericardium or scar tissue. It most often occurs after transmural myocardial infarction, but may also follow cardiac operations, trauma, inflammation, or infection. In contrast to patients with true ventricular aneurysms, those with false aneurysms most commonly die of hemorrhage. Transthoracic echocardiogram, computed tomography scan and cardiac MRI are currently the noninvasive modalities, whereas coronary arteriography and left ventriculography are invasive modalities used for diagnosis. As this condition is lethal, prompt diagnosis and timely management are vital. We present a case report of a patient with no prior risk factors who presented for 1 year with palpitations during exercise and rest, as well as intermittent chest pain. A transthoracic echocardiogram was performed. Echocardiogram revealed an unexpected outpouching of the left ventricle. A computed tomography scan confirmed the diagnosis by revealing a massive left ventricule pseudomanoeuvre. The patient was offered surgery, but he refused the procedure due to the surgical risk.

[Idiopathic sclerosing encapsulating peritonitis: a case report]

La péritonite encapsulante sclérosante est une entité pathologique très rare. C´est une affection fibroinflammatoire chronique du péritoine aboutissant à la formation d´une coque péritonéale fibreuse diffuse engainant totalement ou localement les viscères abdominaux, notamment le tube digestif. Les signes cliniques sont peu spécifiques et trompeurs. L´imagerie médicale, notamment la tomodensitométrie assoie aisément le diagnostic en mettant en évidence une fine membrane péritonéale englobant un agglutinant d´anses digestives. Les formes secondaires (postdialyse péritonéale, tuberculeuse, médicamenteuse, postchimiothérapie intra-péritonéale) sont assez fréquentes, cependant la forme idiopathique reste très rare et peu de cas ont été rapporté par la littérature. Nous rapportons, à travers d´une observation, le cas d´une forme idiopathique chez une femme de 53 ans.

[Rare localization of lipoma in the parotid region: about a case]

La localisation des lipomes au niveau parotidien est très rare. Nous rapportons un nouveau cas avec une revue de littérature concernant un patient de 55 ans, qui a consulté pour une masse au niveau de la région parotidienne évoluant depuis quatre ans. À la palpation nous avons trouvé une formation de consistance molle, mobile et indolore. Le patient a bénéficié par la suite d'une imagerie (échographie et IRM), d'où le diagnostic final d'un lipome parotidien a été retenu ; le traitement était conservateur sur le choix du patient.

Une pneumopathie interstitielle diffuse révélant un syndrome des antisynthétases: à propos de 2 cas

Le syndrome des antisynthétases (SAS) est une myopathie inflammatoire fréquemment associée à une atteinte pulmonaire, surtout parenchymateuse (pneumopathie infiltrante diffuse). Les manifestations extrathoraciques associées à l'atteinte pulmonaire peuvent orienter le diagnostic: myalgies, polyarthralgies, syndrome de Raynaud, hyperkératose érythémateuse palmaire fissuraire et fièvre. Devant un tableau clinique et radiologique évocateur, la présence d'anticorps anti-ARNt synthétases permet de confirmer le diagnostic notamment les anti-Jo1. L'atteinte pulmonaire constitue un facteur pronostic majeur d'où l'indication une thérapie immunosuppressive intensive fondée sur la corticothérapie, les immunosuppresseurs ou l'association des deux. Une meilleure sensibilisation pour cette affection à révélation pulmonaire permettra d'adopter une prise en charge rapide et adéquate, et d'améliorer par conséquent le pronostic.
