Unusual Case of Diffuse Neonatal Hemangiomatosis Case Report and Literature Review.

Diffuse neonatal hemangiomatosis (DNH) is an infrequent condition characterized by the simultaneous occurrence of multiple cutaneous hemangiomas and the involvement of 3 or more organs. DNH is suspected when multiple hemangiomas are identified on the skin of the infant. Although it is benign in nature, DNH can lead to critical and life-threatening complications. Diagnosis primarily relies on clinical evaluation with a significant emphasis on imaging techniques. In this case report, we present an unusual pediatric case of diffuse infantile hemangioendothelioma, for which the investigative approach included ultrasound and CT scans. These imaging methods were instrumental in revealing the presence of lesions in the liver, thyroid, and brain, ultimately playing a pivotal role in making the diagnosis of DNH. A positive clinical and biological improvement was observed with corticosteroid treatment during a 3-month follow-up.

Schizencephaly: A rare cause of late-onset epilepsy in an adult.

Schizencephaly, a rare congenital cerebral deformity that affects the cerebral mantle and is caused by both hereditary and acquired factors, is defined by a cleft that spans the entire cerebral hemisphere from the lateral ventricle to the cerebral cortex. Adult symptoms have only been described in a few cases in the literature. Hemiparesis, developmental delays, or seizures are manifestations of the clinical presentation, which is dependent on the size and location of the lesion. Neuroimaging investigations, particularly MRI, enable the diagnosis and rule out other causes. Usually discovered at birth, this entity begins to show up in the first several years. To prevent receiving the wrong treatment, the ailment must be correctly diagnosed. We report the observation of a 43-year-old patient with partial epileptic seizures but with an asymptomatic childhood, in relation to unilateral closed cleft schizencephaly associated with gray matter heterotopia. In this case, we highlight the importance of neuroimaging, in particular MRI on the diagnosis of this entity and to identify the associated anomalies.

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. Costal origin is infrequently described. In our case, the patient manifested a right anterosuperior chest wall mass. Imaging showed a mass of tissue with a significant zone of osteolysis of the first rib and no chest wall infiltration. Blood protein immunoelectrophoresis disclosed a monoclonal kappa type IgG. Bence-Jones proteinuria was positive, further suggesting a plasmacytoma of the rib. A percutaneous needle biopsy for pathology study and immunohistochemistry enabled the diagnosis of costal plasmacytoma. Search for other localizations was negative and the diagnosis of solitary plasmacytoma was retained. The patient received radiotherapy and has remained in remission for over a year. The pathology and imaging findings are used to make the diagnosis. Radiotherapy is the therapy of choice, but it presents a risk of progression to other bone lesions, medullary plasmacytosis, and multiple myeloma. There are no known factors that predict systemic recurrence. Surveillance is essential on a regular basis.
