Imaging of Madura foot: Case report.

The case presented illustrates a very rare chronic granulomatous disease called the Madura foot or also called mycetoma. It is a chronic granulomatous disease, caused by a contained infection that penetrates the subcutaneous tissues and spreads to the nearby bone by damaging the affected area's vascularization. Early diagnosis is greatly aided by clinical history and imaging, especially if the "dot-in-circle" sign-a pathognomonic marker of mycetoma-is seen on the MRI. Compared to ordinary radiographs, computed tomography offers a more accurate study of changes in the bone. In order to apply the appropriate course of treatment, it is critical to identify the causal species, which can be caused by either a true fungus (eumycetoma) or a bacterium Actinomyces (Actinomycetoma). Treatment can be extremely challenging and can even result in amputation, particularly if the diagnosis is delayed.

Tubercular cerebellitis, identified through an expansive process: A case report.

Central nervous system (CNS) tuberculosis is a postprimary form of tuberculosis with high mortality and morbidity rates, even with early diagnosis and treatment. Focal tuberculous cerebritis is extremely rare, typically occurring in patients without AIDS, and often associated with tuberculous meningitis. In endemic regions, it should be a primary consideration when encountering cerebral anomalies suggestive of granulomatous conditions. Its meningeal pseudo-tumor form poses a significant diagnostic challenge. We present the case of a 26-year-old man who arrived at the emergency room with cerebellar and pyramidal syndrome. Cerebral magnetic resonance imaging (MRI) revealed an expansive lesion in the right hemicerebellum with glove-finger edema and leptomeningeal thickening. Given the MRI findings and associated lung involvement, the diagnosis of tuberculosis was strongly suggested in our epidemiological context. Due to contraindications for lumbar puncture, high surgical risk, and strong clinical and radiological suspicion, antituberculous treatment was initiated in collaboration with neurologists and infectious disease specialists. The clinical and radiologic manifestations of CNS tuberculosis can mimic other infectious and noninfectious neurological conditions, as seen in our patient. Thus, familiarity with the imaging presentations of CNS tuberculosis among infectious disease specialists and radiologists is crucial for prompt and accurate diagnosis.

Total cerebellar agenesis: A case report of a very rare condition.

Complete cerebellar agenesis is an extremely rare condition characterized by the complete absence of cerebellar tissue. Only a small number of cases have been reported, with varying motor and cognitive deficits. We describe a case of an 11-month-old baby with developmental delay, whose CT scan evaluation showed the complete absence of the cerebellum with no other associated cerebral malformation.

Radiology of malignant degeneration of pilonidal sinus: Report of a case and review of the literature.

Pilonidal sinus disease is a frequent and recurrent pathology in young adults, with a male predominance, while malignant transformation of the pilonidal sinus is a rare complication, it occurs in 0.1% of patients, with a poor prognosis. Early surgical removal of the primary lesion remains the best treatment. We report a case of malignant transformation of pilonidal disease into squamous cell carcinoma.

Congenital infiltrating lipomatosis of the face: Case report.

A rare disorder called congenital infiltrating lipomatosis of the face is characterized by a diffuse fatty infiltration of the soft tissues of the face. Muscle involvement and related bony hyperplasia may coexist. This particular form of lipomatous tumor is rare and typically appears in childhood. It is congenital in nature. Collections of mature, nonencapsulated lipocytes that infiltrate local tissues and frequently recur following surgery define congenital infiltrating lipomatosis, a unique clinicopathologic condition. The best modalities are, CT scan and MRI since they can determine the extent of the lesions and reveal their fat content. The treatment of this disease is surgical as soon as possible to restrict their infiltrative growth and improve the appearance of the face. We describe a case of massive facial invading lipoma that was investigated using MRI.

Madura foot: How MRI aids in diagnosis.

A 46-year-old farmer living in a rural area, who sustained an injury to his left foot 10 years ago, consulted due to progressive swelling of the same foot. An MRI revealed the "dot-in-circle" sign, suggestive of mycetoma of the foot, also known as Madura foot. This condition primarily affects soft tissues and bones and can occasionally lead to potentially severe visceral complications. Foot involvement is predominant, observed in 80% of cases.

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.

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.

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.

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.

Cerebellar liponeurocytoma: Rare posterior fossa tumor.

Cerebellar liponeurocytoma is a rare WHO grade II glioneuronal tumor, characterized by a benign course and a more favorable prognosis. In this paper, we report a 52-year-old man, hospitalized in emergency because of clinical signs of increased intracranial pressure, and gait disturbances. The MRI revealed a lateral well shaped solid lesion within the left cerebellar hemisphere, having a low signal intensity compared to the cerebrospinal fluid, and causing a triventicular hydrocephalus and tonsillar herniation. The patient underwent a direct approach of the tumor through a left suboccipital craniectomy. Total removal of the lesion was achieved, and the histological diagnosis was cerebellar liponeurocytoma. The tumor cell proliferation index was < 6 %, therefore, radiotherapy and chemotherapy were not implemented after surgery. After 5 years of close follow-up there were no clinical or radiological signs of recurrence. Our objective in reporting another case of this unusual tumor is to discuss clinical profile, radiologic and histologic features as well as treatment and prognosis of this rare posterior fossa tumor.

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.

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.

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.

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.

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.
