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. It is important to consider tuberculosis in the differential diagnosis of sellar-suprasellar masses in the pediatric population, especially in areas with a high prevalence of tuberculosis. Case Description: A 17-year-old male with no history of illness showed up with a series of symptoms, including headaches and vision problems. A sellar-suprasellar lesion was seen on imaging, along with several minor lesions. The diagnosis of tuberculosis meningitis with cerebral and pituitary tuberculoma was made after cerebrospinal fluid analysis revealed the presence of tuberculosis. Treatment with anti-tuberculosis drugs led to clinical improvement and lesion resolution. Conclusion: Children's sellar tuberculomas can be difficult to diagnose since they resemble other pituitary tumors. It is essential to take them into account in the differential diagnosis, especially in regions with a high incidence of tuberculosis. Long-term chemotherapy is the recommended course of treatment, and monthly follow-up visits are necessary to check hormone levels and evaluate whether a permanent hormone replacement is necessary.

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. This case highlights the importance of careful analysis of imaging findings and the need for consideration of all possible diagnoses, including rare or atypical presentations of common neoplasms such as meningiomas. Early detection and accurate diagnosis are crucial in determining the appropriate management and improving the outcomes for patients with intracranial tumors.

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. However, 2 months prior to admission, the movements worsened and were accompanied by symptoms of intracranial hypertension. The neurological examination revealed a coordination disorder, specifically a tremor, along with impairment of thermo-algic sensitivity. Ophthalmological examination was unremarkable, but the MRI indicated a colloid cyst of the third ventricle. A minimally invasive neuro-endoscopy procedure was chosen as the treatment of choice for our patient. The bobble head doll syndrome is a complex neurological disorder, and imaging is crucial in the diagnosis and treatment of any movement disorder to enable an early diagnosis and treatment.

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. Conclusion: Spontaneous regression of solid-cystic VS is possible but rare, it can be part of conservative treatment, which requires regular follow-up.

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.

Failure to Thrive Revealing a Pilomyxoid Astrocytoma: An Uncommon Case Report with Literature Review.

Pilomyxoid astrocytoma (PMA) is a freshly described figure of low-grade neoplasms encountered in early childhood. Nevertheless, its precise classification by the World Health Organization (WHO) is still debatable. Making an exact diagnosis relies on histological and immunohistochemical pathognomonic features with specific radiological findings. PMA behaves aggressively with a shorter progression-free survival, and its management is unfortunately still arguable. We describe a rare case of PMA involving the suprasellar region who displays symptoms consistent with diencephalic syndrome. The diagnosis was made by magnetic resonance imaging (MRI) focused on the hypothalamic-pituitary axis, and the patient underwent a subtotal tumor resection combined with chemotherapy. Diagnosis of brain tumors should be kept in mind in young children with generalized and severe unexplained loss of subcutaneous fat with failure to thrive after ruling out classical causes.

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. Laboratory tests determine hormone deficiencies orientating replacement therapy's protocol. MRI of the hypothalamic-pituitary region is crucial in exhibiting major radiological signs such as pituitary homogeneous enlargement and gland stalk's thickening. The etiological diagnosis is still challenging without affecting the management strategy. Corticosteroids have widely been used but a close follow-up without any treatment has also been approved. CASE DESCRIPTION: In this report, seven patients with hypophysitis have been collected over a period of 6 years. The average age of our patients was 32.1 years ± 11.8 with a female predominance (71.4%). Panhypopituitarism was objective in 42.9% of cases, a combined deficiency of the hypothalamic-pituitary thyroid, adrenal and gonadal axes in 28.6% of cases. A central diabetes insipidus was noted in 42.9% of the patients. Idiopathic hypophysitis was the most common etiology. The use of long course corticosteroids was required in 28.6% when compressive signs were reported. CONCLUSION: Hypophysitis remains a rare disease with nonspecific clinical and radiological patterns. Autoimmune origin seems to be the most frequent etiology. No guidelines have been established for hypophysitis management and the evolution is still unpredictable.

[Extra-axial chordoid meningioma: a case report]. / Méningiome chordoïde extra-axiale: à propos d'un cas.

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. Total tumor excision was performed. Histological examination showed chordoid meningioma.

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

INTRODUCTION: Intracranial arachnoid cysts (ACs) are space-occupying lesions that typically remain stable in size and clinically silent over time. CASE REPORT: We describe an unusual pediatric case of enlarged AC impressive by its compressive phenomena. An 11-month-old girl presented with remarkable macrocephaly associated with a cystic orbital tumor. CT scan and MRI studies revealed a large intracranial ACs extending in the orbit with an orbital meningocele (OM). The intracranial cyst did communicate with the orbital one into a bony defect in the right inner region of the orbital roof and represses the globe outward. A cystoperitoneal shunting procedure was performed to remove the mass effect as soon as possible and facilitate normal development. DISCUSSION/CONCLUSION: Cysts in infants younger than 1 year of age are remarkably different from those in older children and adults in terms of cyst localization and enlargement. Classically described complications result from compression of adjacent structures and include focal neurologic involvement, headaches and seizures and developmental deficits, or macrocephaly in younger children. There are few cases of ACs with ophthalmic manifestations reported in the literature. The paucity of literature prompted us to analyze the case. To the best of our knowledge, an AC accompanying OM has not been reported. The pathogenesis and management of the case will be discussed.

Neurosyphilis revealed by compressive cervical spine syphilitic gumma: a case report.

INTRODUCTION: Neurosyphilis is a sexually transmitted disease secondary to the invasion of the central nervous system by the Treponema pallidum. The spinal syphilitic gumma is rare. CASE PRESENTATION: We report a case of extradural cervical spinal syphilitic gumma revealed by spinal cord compression in a 58-year-old male. The epidural lesion was removed via a posterior approach. Histological examination revealed syphilis. Syphilis serologies were positive. Brain MRI showed an associated cerebro-meningeal syphilitic gumma. Antibiotic regime based on aqueous penicillin G was introduced for 14 days. DISCUSSION: Currently, there is an increase in the frequency of syphilis and changes in its clinical manifestations. Neurosyphilis can take atypical forms. Spinal syphilitic gumma is a rare manifestation and its association with cerebral involvement is exceptional. Diagnosis is based on serologies in the blood and cerebrospinal fluid. The place of imagery, especially magnetic resonance imaging, is essential. Neurosyphilis should be discussed as a possible differential diagnosis in evaluation of spinal and cerebral lesions.

[Pseudo-tumor form of neuro-Behçet disease: case study and literature review]. / Une forme pseudo-tumorale du neuro-Behçet: à propos d'un cas et revue de la littérature.

Mass lesions of the brain are not always a tumor. We report the case of a patient followed for Behcet syndrome presenting with expansive intracranial process revealed by right hemiparesis associated with signs of intracranial hypertension. Brain magnetic resonance imaging (MRI) showed a lesion suggesting glial tumor. Clinical and radiological assessments as well as laboratory tests helped to establish the diagnosis of pseudo-tumor form of neuro-Behçet disease. This study report is followed by a clinical analysis based on the available literature on this disorder.
