Uncommon spinal involvement of ALK-positive anaplastic large cell lymphoma: A pediatric case report and literature review.

Anaplastic large cell lymphoma (ALCL) is a rare variety of non-Hodgkin lymphoma that primarily affects children and young adults and is caused by the fusion of the nucleophosmin 1 and ALK genes, which turns on several signalling pathways. Despite the fact that ALCL frequently affects lymph nodes and extranodal sites, involvement of the central nervous system (CNS) is quite uncommon, with symptoms like pain and fever. The spinal localization may result in neurological impairments.

Pediatric sellar-suprasellar tuberculosis: A case report and review of the literature.

Background: Pediatric sellar-suprasellar tuberculosis is a rare form of tuberculosis that affects the pituitary gland and surrounding areas in the brain. It can be difficult to diagnose based on clinical and radiological signs alone, as they can be similar to other pituitary masses. A combination of biological, hormonal, and imaging examinations can aid in making an accurate diagnosis.

Atypical radiological aspect of meningioma: Web-like enhancement.

Meningiomas are the most common extra-axial neoplasmof the central nervous system (CNS). There are a number of characteristic imaging features of meningiomas on magnetic resonance imaging (MRI) that allow an accurate diagnosis, however there are a number of atypical features that may be diagnostically challenging. Furthermore, a number of other neoplastic and non-neoplastic conditions may mimic meningiomas.

Bobble head doll syndrome (BHDS): Case report.

The bobble head doll syndrome is a rare neurological disorder characterized by repetitive and involuntary movement of the head that typically appear in childhood. It is usually associated with the dilatation of the third ventricle and one or more cystic lesions that can be treated surgically. We present the case of a 7-year-old girl with a history of autism, who has experiencing repetitive up and down head movements for 2 years, which were initially thought to be stereotypies.

Spinal mesenchymal chondrosarcoma: A case report of a rare malignant tumor.

Background: Mesenchymal chondrosarcoma is an uncommon malignant variant of chondrosarcoma that mainly affects the bones and cartilaginous tissues, but may rarely involve the spine. Careful preoperative planning for surgical tumor removal and spine reconstruction is mandatory and must be based on oncologic and surgical staging.

Case Description: Over 1 month, a 16-year-old female became paraplegic with a T9 sensory level and urinary dysfunction.

Spontaneous regression of solid-cystic vestibular schwannoma: A case report.

Background: Vestibular schwannomas (VSs) are one of the most common tumors of the cerebellopontine angle and internal meatus, the evolution of this type of tumors is defined as unpredictable, it can enlarge or present a spontaneous regression as described in rare cases.

Case Description: We report the case of a 50-year-old woman who presented with a large right full cystic VS revealed by a balance disorder associated with deafness in the right ear which spontaneously regressed. The patient was lost to follow-up for 3 years, the symptomatology improved, and the tumor clearly regressed without any surgical treatment.

The white cerebellum sign with good prognosis: A case report.

The white cerebellum sign is a radiologic sign rarely described resulting from diffuse cerebral edema, reported especially in children with hypoxic brain lesions, it is usually associated with poor prognosis leading to irreversible brain damage. We report the case of a child who presented this sign after a severe head injury and differently from most of previous cases, our patient has recovered very successfully. The white cerebellum sign is a radiologic sign that is not frequently described, which when present carries a poor prognosis, one third of the patients die and the others have severe deficits, its identification is necessary for a better patient management.

Acute total aortic dissection revealed by incoercible vomiting with multiple organ failure a case report.

Introduction And Importance: Acute aortic dissections are an uncommon entity. The different clinical manifestations especially in younger patients with no predisposing factors make it challenging to diagnose, causing delayed care and high mortality.

Case Presentation: In this report we describe a case of a total aortic dissection in a young man revealed by intractable vomiting with abdominal and chest pain.

Severe hypercalcemia complicated by acute pancreatitis revealing generalized bone lysis metastasis: Case report and review.

Malignant hypercalcemia is a frequent metabolic complication of osteophilic tumors, exceptionally revealing cavitary cancer, but its prognosis remains poor despite early and adequate management. We report the case of a young patient, smoker without any previous history, admitted for the management of a digestive symptoms made of abdominal pain with food vomiting. The patient had an electrocardiogram withchest computed tomography scan and BBC evoking PA on malignant hypercalcemia.

Post Myocardial Infarction Ventricular Septal Rupture Revealed By Acute Liver Failure Symptoms: A Case Report.

Introduction: The mechanical complications of acute myocardial infarction (AMI) still kill despite the evolution of medicine. Early diagnosis and adequate management are necessary to improve the prognosis, and this requires first, a good clinical examination that should raise the suspicion of a mechanical complication, then the echocardiography is performed to confirm the diagnosis.

Case Presentation: We present a case of a 64-year-old patient admitted to the emergency room for jaundice with delayed ST-segment elevation myocardial infarction (STEMI).

Cerebral Salt Wasting Syndrome (CSW): An unusual cause of hypovolemia after spontaneous cerebral hemorrhage successfully treated with fludrocortisone.

Our objective is to demonstrate the interest of thinking about Cerebral salt wasting syndrome (CSW) in front of hyponatremia with severe hypovolemia after a brain injury, and at the same time the interest to differentiate between Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) and Cerebral salt wasting syndrome (CSW) as two etiologies to be evoked in front of a hyponatremia with brain injury. We report the case of a 63-year-old patient with a recent history of hemorrhagic stroke admitted for severe hypovolemic shock in whom the investigations find a very deep hypotonic hyponatremia secondary to a cerebral salt wasting syndrome successfully treated with fludrocortisone. CWS is characterized by hypotonic hyponatremia associated with cerebral associated with hypovolemia, the difficulty of the diagnosis is explained by the points of convergences with SIADH which is also presented with hyponatremia.

Clinical presentation and management of hypophysitis: An observational study of case series.

Background: Hypophysitis is described as a rare chronic inflammatory affection of the pituitary gland. However, to date, its pathogenesis has not been completely cleared up. Clinical features are polymorphic, including symptoms related to inflammatory compression and/or hypopituitarism.

[Extra-axial chordoid meningioma: a case report].

This study reports the case of a 45-year-old female patient who underwent brain CT scan which fortuitously revealed de novo lesion. She was diagnosed with left isodense intradiploid lesion in the pterional region with bone lysis uniformly enhancing after injection of contrast medium. Magnetic resonance imaging showed T1-weighted hypointense lesion, spontaneously hyperintense signal on T2-weighted images and FLAIR images, strongly enhancing after gadolinium injection.

Giant Arachnoid Cyst Associated with an Orbital Meningocele: A Case Report and Cystoperitoneal Shunt Management.
