The neuropathic osteoarthropathy of the hip: About two cases.

The neuropathic osteoarthropathy are ectopic ossifications, developed near the joints, secondary to a process of neo-osteogenesis in the case of central neurological lesions and rarely peripheral lesions. We report the case of two patients aged of 7 years and 35 years, for whom the CT scan allowed us to make the positive diagnosis, and an accurate preoperative assessment, by studying the seat, the vessels and nerves, allowing an adapted and precocious management. We propose an update of neuropathic osteoarthropathy based on data from the literature.

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.

Imaging appearance of ovarian dysgerminoma: A report of two cases.

Ovarian dysgerminoma is a rare germ cell tumor accounting for 1%-2% of all malignant ovarian tumors and is generally associated with a good prognosis. The condition is more frequent in young women and can arise in dysgenetic gonads that contain gonadoblastomas. Imaging findings, particularly MRI, have a prominent role in the early and correct identification of ovarian dysgerminoma, the most common ovarian malignant germ cell tumor. On CT and MR images, ovarian dysgerminoma often appears as a large, solid mass. The edematous condition of characteristic fibrovascular septa can be well displayed by imaging, which can guide the radiologists to make an accurate diagnosis. This article describes 2 cases of patients with ovarian dysgerminoma who presented with pelvic pain. Imaging showed a right ovarian mass that was surgically and histologically confirmed.

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.

Carotid occlusion of a giant intracavernous aneurysm on a single functional internal carotid artery.

The prevalence of intracranial aneurysms (IA) is higher in patients with stenosis of the internal carotid artery (ICA), the intracavernous internal carotid aneurysm is an intracranial aneurysm causing major functional and vital complications. We report the case of a 26-year-old man who consulted for a reduction in visual acuity, converging strabismus and ptosis of the right eye evolving for 7 months before his consultation, the various neuro-radiological examinations made it possible to identify diagnose a giant aneurysm of the right intracavernous internal carotid artery associated with severe stenosis of the contralateral internal carotid artery, hence the performance of a therapeutic arteriography consisting of an occlusion of this aneurysm. In summary, we describe successful management of a giant aneurysm of the intracavernous portion of a single functional internal carotid artery, while preserving optimal cerebral vascularization.

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.

Ileal intussusception secondary to lipoma in an adult patient: A rare cause for intestinal obstruction: A case report.

Intussusception is a rare condition in adults, unlike in children, with a variety of etiologies. In most cases, it is secondary to tumors. acute intussusception on lipoma is very exceptional. We report a case of 68-year-old female patient, diagnosed with intestinal intussusception on lipoma.

Pes anserine bursitis as a complication of tibial osteochondroma.

Exostosis, or osteochondroma, represents the most prevalent primary benign bone tumor, often viewed as a developmental anomaly rather than a true neoplasm. This article presents 2 cases illustrating complications associated with tibial osteochondroma. The first case involves a 25-year-old patient with recurrent medial knee pain attributed to pes anserine bursitis secondary to tibial osteochondroma, managed successfully with surgical excision. The second case features a 15-year-old with similar symptoms and unsuccessful conservative management, highlighting the diagnostic challenges and therapeutic options for this condition. Discussion encompasses the clinical presentation, diagnostic modalities including MRI and ultrasound, and management strategies such as conservative measures, corticosteroid injections, and surgical excision. Recognizing and promptly managing complications like pes anserine bursitis in tibial osteochondroma is crucial to prevent chronic pain and functional impairment, emphasizing the importance of a multidisciplinary approach involving orthopedic surgeons, radiologists, and physical therapists.

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.

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.

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.

A rare cause of bronchial obstruction: Endobronchial hamartoma case report.

Most of the pulmonary endobronchial lesions are malignant in origin. In rare instances, benign lesions such as endobronchial hamartoma may be the cause of the endobronchial tree obstruction. We present the case of a 57-year-old male patient from North Africa who presents with a history of a 5-month cough. Imaging, particulary CT scan, showed a mass on the right intermediate bronchus whose radiological characteristics are consistent with hamartoma. A biopsy of the mass obtained via bronchoscopy revealed chronic inflammation with no evidence for malignancy. The patient was treated surgically, and anatomopathology confirmed the diagnosis of hamartoma.

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.

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.

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.

Pelvic cellulitis, a rare complication of bartholinitis: report of two cases.

Pelvic or pelviperineal cellulitis is a rare but serious complication of bartholinitis and can be life-threatening. It is described of polymicrobial nature. The diagnosis of pelvic cellulitis remains essentially clinical with signs of local inflammation. The interest of imaging, CT in particular, is to assess the extent of the infection and abcess. In this report, we describe 2 cases of pelvic cellulitis complicating a bartholin's abscess caused by negative gram bacilli in 2 diabetic women in their sixties.

Mediastinal and pericardial hydatidosis: A case report with review of the literature.

Hydatidosis is an echinococcosis caused by the development of Echinococcus granulosus larvae in humans. The lung is the second most frequent site after the liver. The primary mediastinal and pericardial localisations are extremely rare. Ultrasound and CT scans play an important role in the diagnosis of this disease.We report the case of an 11-year-old female patient from a rural environment with a history of dogs contact, whose symptomatology consisted of chest pain, dyspnoea, all evolving in a febrile context. The imagery showed the existence of multiple mediastinal and pericardial collections. This patient was rapidly managed with albendazole (ABZ) and scanography revealed an excellent therapeutic response. Primary mediastinal and pericardial hydatidosis is a very uncommon disease. It can be unfortunately revealed at the stage of vital prognosis complications. Ultrasound and computerized tomography (CT) are helpful for localizing and defining the morphologic features of hydatid cysts. It should be kept in mind, especially in patients from endemic areas.

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.
