Congenital Midface Abnormalities
There are a wide variety of congenital midface abnormalities that originate during transformation of the first pair of pharyngeal arches into adult structures. Computed tomography and magnetic resonance imaging are…
Development and Dysgenesis of the Cerebral Cortex: Malformations of Cortical Development
The cerebral cortex develops in several stages from a pseudostratified epithelium at 5 weeks to an essentially complete cortex at 47 weeks. Cortical connectivity starts with thalamocortical connections in the…
Demystifying Congenital Malformations for Imaging Specialists
Hemant A. Parmar, MD, Guest Editor Mohannad Ibrahim, MD, Guest Editor Pediatric neuroimaging is generally challenging for radiologists. Like in other areas of pediatric imaging, understanding congenital malformations of the…
Vascular Brain Pathologies
Vascular pathologies of brain comprise a heterogeneous group of abnormalities such as vasculitis, dural arteriovenous malformations, carotid-cavernous fistulas, cerebral venous thrombosis, and intracerebral hemorrhage. Modern imaging techniques are increasingly unraveling…
Parasitic Diseases of the Central Nervous System
This article reviews the characteristic imaging appearances of parasitic diseases of the central nervous system, including cysticercosis, toxoplasmosis, cystic echinococcosis, schistosomiasis, amebiasis, malariasis, sparganosis, paragonimiasis, and American and African trypanosomiases….
Relevance of Neuroimaging in the Diagnosis and Management of Tropical Neurologic Disorders
The development in neuroimaging techniques has revolutionized the way neurology is practiced, including neurologic disorders in tropics. Some diseases occur exclusively, whereas some are more common in tropical regions. However,…
Neuroimaging in Acute Transverse Myelitis
Transverse myelitis is an acute inflammatory condition. A relatively rare condition, the diversity of causes makes it an important diagnostic challenge. An approach to the classification and work-up standardizes diagnostic…
Neuroimaging in Postinfectious Demyelination and Nutritional Disorders of the Central Nervous System
The myelin sheath and oligodendrocytes in the brain may be damaged by autoimmune-mediated inflammatory processes secondary to postinfectious demyelination or nutritional and vitamin deficiency. This article describes acute disseminated encephalomyelitis,…
Neuroimaging in Craniovertebral Anomalies as Seen in the Tropics
Craniovertebral junction (CVJ) disorders in the Occident are usually associated with systemic disorders. In contrast, in the Orient, a greater incidence of isolated CVJ anomalies is seen. Although these are…
Pyomyositis
Pyomyositis is the primary infection of the skeletal muscle. It is common in the tropics, but is increasingly being reported worldwide. It can affect immunocompromised and immunocompetent individuals. Staphylococcus aureus…
