CT and MR imaging of a huge retroperitoneal synovial sarcoma: A case report.

Retroperitoneal synovial sarcoma is extremely rare, with only a few cases reported in the literature. The diagnosis is often made late, due to anatomical considerations, with common symptoms including low back pain and weight loss. Imaging is critical for diagnosis, often revealing a heterogenous mass with the "triple sign" and calcifications.

Clinical report of metacarpal melorheostosis: a rare disease with "the dripping candle wax" appearance on different imaging modalities.

Melorheostosis is a rare benign bone dysplasia characterized by dysostosis and sclerosis. The classic "dripping candle wax" appearance on imaging is a typical finding for the diagnosis. The authors report the case of a patient presenting with a hard and painful mass on the dorsal side of the hand.

Transposition of the inferior vena cava with hemiazygos continuation: A rare case report.

Hemiazygos continuation of a left-sided inferior vena cava (IVC) is an extremely rare developmental anomaly. We present the case of a male patient in whom this condition was incidentally discovered during a thoraco-abdominopelvic CT scan. With the widespread use of contrast-enhanced computed tomography and magnetic resonance angiography, the detection of congenital IVC anomalies has become more accessible.

Congenital right optic nerve colobomatous cyst associated with microphthalmos.

Optic nerve coloboma is a congenital defect caused by the incomplete closure of the embryonic fissure. This closure begins around the fifth week of gestation, when the embryo measures approximately 7 to 14 mm. Colobomas may appear as isolated defects or alongside other ocular and systemic abnormalities.

Transgastric migration of retained intraabdominal surgical sponge: Gossypiboma in the fundus.

The retention of a surgical sponge is a rare complication that presents diagnostic challenges and carries the risk of potential complications. Two distinct foreign body reactions, fibrinous, and exudative, can result in the formation of a granuloma (known as gossypiboma) or lead to complications such as abscess formation and migration into the gastrointestinal tract. In this report, we present the case of a 33-year-old woman with a history of splenectomy who presented with symptoms including epigastric pain, vomiting, and episodes of hematemesis.

Massive brown tumors of the jaw: A case report.

Brown tumors are non-neoplastic bone lesions caused by an abnormal remodeling of the bone that may occur with primary or secondary hyperparathyroidism. Their radiological aspect: lytic and aggressive can easily be misdiagnosed for a malignant origin hence the importance of knowing that diagnosis is to be considered through both clinical context and radiological semiology, which will be detailed via this case of a 32-year-old female patient with an end-stage kidney disease, admitted for facial disfiguration and palpable masses corresponding to brown tumors affecting the maxilla and the mandibular bone.

Congenital bilateral perislyvian syndrome: A rare case report.

Congenital bilateral perisylvian syndrome, also known as bilateral periopercular syndrome or perisylvian polymicrogyria, is an exceptionally rare neurological disorder characterized by homogeneous clinicoradiological symptoms. There are consequently wide spectrums of clinical manifestations. In perisylvian syndrome.

A misleading tumor: A rare form of infantile fibromatosis.

Infantile fibromatosis is a rare mesenchymal disorder characterized by the fibrous proliferation of the skin, bone, muscle, and viscera. The clinical features vary from solitary to multicentric forms with similar pathological features. Although the tumor is histologically benign, it is a highly infiltrating lesion making the prognosis poor for patients with craniofacial involvement affection due to the major risk of nerve vascular and airway compression syndrome.

Solitary plasmacytoma of the rib: A rare tumor to keep in mind: Case report.

Around 5% of plasma cell neoplasias are solitary plasmacytomas, a tumor that is fairly rare. The presence of a localized tumor composed of monoclonal plasma cells that are the same as those found in multiple myeloma and the absence of symptoms that would suggest a disseminated form are used to establish the diagnosis. The thoracolumbar spine is the area most affected.

Primary amenorrhea secondary to imperforate hymen.

Hymen imperforation is uncommon. Symptoms include primary amenorrhea, cyclical lower abdominal pain, and rarely a pelvic mass syndrome. Delayed discovery may lead to endometriosis and infertility.

Ruptured Pyogenic Liver Abscess as an Uncommon Cause of Pneumoperitoneum.

Spontaneous ruptured gas-forming pyogenic liver abscess (GFPLA) is a life-threatening infection that mimics perforation of hollow viscous and need to be accurately diagnosed by computed tomography, which in turn helps to decrease the operative time and improve patient's prognosis.

Bronchial tear consecutive to blunt chest trauma.

Tracheobronchial injuries following blunt chest trauma are rare and can be lethal. CT scan can help to diagnose it when a defect to the tracheobronchial wall is visible or to suspect it in front of indirect signs.

Unruptured aneurysm with intramural thrombus is an unusual cause of spinal cord infarction: a case report.

Infarction of the spinal cord is a rather rare occurrence. Paraparesis or quadriparesis with vibration and proprioceptive senses sparing are symptoms of anterior cord syndrome. Ischemic anterior cord syndrome can result from an obstruction of the anterior spinal artery or the Adamkiewicz Artery.

Cadasil syndrome: A case report with a literature review.

"CADASIL" is a genetic microangiopathy with autosomal dominant inheritance. Its epidemiology and physiopathogenesis are poorly specified, but it is proven that this disease is due to a mutation of the NOTCH3 gene resulting in a loss of elasticity of the media of the affected vessels. The clinical expression is variable, dominated by migraine attacks with aura, ischemic vascular accidents and psychiatric disorders, in particular depression.

An unusual presentation of hydatid cyst: A tight mass a case report with a literature review.

Hydatidosis is a worldwide infectious disease caused by the larval form of a parasitic tapeworm of helminths affecting mainly the liver and lungs in cattle- and sheep-raising regions. Muscle localization remains extremely rare and its diagnosis is sometimes challenging. We report the case of a 45-year-old man presenting with a swelling of the left thigh gradually increasing in size.

Cerebellar hemangioblastoma: Case report with review of the literature.

Originally recognized by Cushing and Bailey, hemangioblastoma is a developmental vascular neoplasm that is predominantly found in the posterior fossa. It is a highly vascularized tumor, with well-differentiated histologic features. Although rare, it remains the most common primary tumor of cerebellum in adults, along with metastases.

Scrotal leiomyoma: An uncommon cause of chronic scrotal swelling.

Leiomyoma is a benign tumor that arises from smooth muscle. It may be encountered at any part of the body especially the uterus. However, scrotal localization is very uncommon, hence it often requires radiologic and pathology correlation to establish an accurate diagnosis and make optimal decisions for subsequent treatment.

Cutaneous metastasis as a first sign of breast carcinoma.

Unlike visceral, lymphonodal or bone metastases, skin metastases are rare and their identification portends of a bad prognosis. They may appear as the first sign revealing the primary tumour, synchronous or developing late in the course of neglected primary cancer. We report a case of 86 year-old women witch belongs to this rare group of patients in whom cutaneous metastasis were identified before the primary cancer.

Tuberculous common bile duct stricture mimicking a cholangiocarcinoma: A case report.

Biliary involvement during abdominal tuberculosis is extremely uncommon and represents a challenging diagnosis that can easily be mistaken for a malignant etiology. We report the case of a 40 years old male who presented with anorexia, chronic abdominal pain, and progressive obstructive jaundice. Abdominal computed tomography demonstrated distal narrowing with wall thickening of the main biliary duct, along with enlarged lymph nodes and signs of portal hypertension.

A rare cause of exophthalmia: Osteoblastoma of the frontal sinus.

Osteoblastoma is a rare benign tumor arising predominantly in the vertebrae or long tubular bones. Its naso-sinusian origin is rare and can be responsible for ophthalmological complications [1]. We report the case of 19-yeaold patient admitted to the Ophthalmology department for progressive right exophthalmia and ptosis evolving over 8 months.
