Case Report: Unusual High-Grade Diffuse Leptomeningeal Glioneuronal Tumor Mimicking Tuberculous Meningitis in a Child From an Endemic Region.

Diffuse leptomeningeal glioneuronal tumor (DL-GNT) is a new entity described in the 2016 World Health Organization (WHO) classification of brain tumors. While DL-GNT is predominantly an indolent tumor that affects young boys, high-grade DL-GNT is unusual and seldom reported in children. In this report, we describe the challenges and pitfalls associated with diagnosing this high-grade variant in a tuberculosis-endemic region.

Missed tuberous sclerosis complex with multi-system complications in a single patient.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by widespread clinical manifestations. Early diagnosis is usually possible when typical TSC related skin lesions and neurologic presentations are detected in young patients. Undiagnosed TSC patients are at increased risk of morbidity and mortality as disease progression will inevitably lead to complications.

Congenital colorectal tubular duplication in an infant: A tale of radiological diagnostic challenges.

Enteric duplications (EDs) are rare congenital anomalies that result from defect during embryonic development of the gut. Although EDs can literally occur at any part of the gastrointestinal tract, ileocecal duplication is the commonest type followed by colorectal type. Morphologically, EDs are mostly cystic in nature; tubular duplications are uncommon.

Wilms tumor presenting as small bowel obstruction in a neonate: A diagnostic challenge.

Wilms tumor is the most common primary malignant renal tumor of childhood which usually presents between 2 and 6 years of age. Its presentation in the neonatal period is extremely rare and presenting with intestinal obstruction is perhaps unknown. We report a 2-day-old baby girl who manifested features of acute upper gastrointestinal obstruction with frequent post-feeding vomiting and abdominal distension.

MR imaging of hypothalamic hamartoma in a patient with gelastic seizures.

Hypothalamic hamartomas (HHs) are non-neoplastic malformations that occur in the region of the hypothalamus. HH is the leading cause of gelastic seizures in children and adolescents, where laughing is characteristically manifested. However, these patients can also experience different forms of complex or generalized tonic-clonic seizures that can obscure the diagnosis of HHs.

Rare late-presentation congenital diaphragmatic hernia mimicking a tension pneumothorax.

Congenital Diaphragmatic Hernia (CDH) is due to a defect in the diaphragm and is usually detected soon after birth. However, in rare cases, asymptomatic CDHs can be missed and present later in life. Late-presentation CDH can be misdiagnosed as tension pneumothorax leading to iatrogenic complications.

Asymptomatic complete distal abdominal aortic occlusion with initial presentation of ruptured intracranial aneurysm.

Aortoilliac occlusive disease is occlusive atherosclerosis disease involving the distal aorta and bifurcation of iliac arteries and it is a subtype of peripheral arterial disease. Total occlusion of the abdominal aorta is a rare occurrence with an incidence of 3% -8.5% among the aortoiliac occlusive disease patients.

Skull Base Primary Ewing Sarcoma: A Radiological Experience of a Rare Disease in an Atypical Location.

BACKGROUND Ewing sarcoma and primitive neuroectodermal tumor are rare tumors grouped under the spectrum of the Ewing sarcoma family of tumors. These highly malignant tumors involve the bones and commonly occur in children. Ewing sarcoma of the skull bone accounts for only 1% of all Ewing sarcomas, with primary skull base Ewing sarcoma occurring in less than 1% of cases.

Empyema thoracis presented as giant back abscess.

Empyema thoracis (ET) is defined as pus in the pleural space, either localized or involving the entire pleural cavity, due to diverse etiologies. In severe form, it may infiltrate the extrapulmonary region. Clinical guideline describes 3 stages of parapneumonic effusion before developing into an ET, namely the exudative stage, the fibrinopurulent stage, and the organizing/late stage.

Case report: Ballotable abdominal mass in a child - Definitely renal in origin?

Introduction And Importance: The differential diagnosis of a paediatric abdominal mass can be extensive, as it potentially involves multiple organs including gastrointestinal, genitourinary, endocrine, and gynaecological systems. Hence, a systematic approach to history taking and physical examination is needed to clinch the diagnosis. Specifically, the approach for assessing, investigating, and managing a ballotable left hypochondrial mass in a child can be challenging.

Emphysematous gastritis after metastatic malignant melanoma: a radiological surprise.

Malignant melanoma is cancer of the skin which commonly metastasises to the stomach. There have been no reported cases of emphysematous gastritis secondary to metastasis of malignant melanomas, to date. However, a 61-year-old woman with metastatic malignant melanoma of the left great toe presented to us with symptoms of severe left hypochondrium pain associated with high-grade fever, gross abdominal distension and recurrent vomiting.

Giant submandibular sialolipoma masquerading as huge goitre: a case report.

Background: Sialolipoma is a rare tumour which may arise from both major and minor salivary glands and has recently been described as a variant of salivary gland lipomatous lesions.

Case Presentation: We report a 54-year-old male who presented with a 7-year history of large right anterior neck swelling. He was clinically euthyroid and had no compressive or infiltrative symptoms.
