Band form
Like focal subcortical heterotopia, "band" heterotopia form in the white matter beneath the cortex, but the gray matter is more diffuse and is symmetric between the hemispheres. On imaging, band heterotopia appears as bands of gray matter situated between the lateral ventricle and cerebral cortex and separated from both by a layer of normal appearing white matter. Band heterotopia may be complete, surrounded by simple white matter, or partial. The frontal lobes seem to be more frequently involved when it is partial. Patients with band heterotopia may present at any age with variable developmental delay and seizure disorder, which vary widely in severity. Subcortical band heterotopia, also known as "double cortex" syndrome, refers to a band of subcortical heterotopia neurons, located midway between the ventricles and the cerebral cortex. The disorder is seen primarily in females and typically causes varying degrees of intellectual disability and almost all of them have epilepsy. Approximately two thirds of patients with epilepsy ultimately develop intractable seizures. MRI of the brain in subcortical band heterotopia demonstrates two parallel layers of gray matter: a thin outer ribbon and a thick inner band, separated by a very thin layer of white matter between them. The severity of epilepsy and developmental delay is directly correlated with the degree of migration arrest, as indicated by the thickness of the subcortical band heterotopia. Subcortical band heterotopia is caused by mutations in the microtubule-associated DCX gene.
Additionally, irrigating the bladder with distilled water three times daily with 3 way Foleys catheter and urinary antiseptics like pyridium may be used to help relieve urinary symptoms. Antibiotics such as trimethoprim-sulfamethoxazole or ciprofloxacin may be used. History
Leonor Michaelis and Carl Gutmann first described malakoplakia in 1902 after analyzing a patients tumor at the request of David Paul von Hansemann. See also
