Search for a rare disease Summary. Periventricular nodular heterotopia (PNH) is a brain malformation, due to abnormal neuronal migration, in which a subset of neurons fails to migrate into the developing cerebral cortex and remains as nodules that line the ventricular surface.

Chest X-ray Abnormalities Hilar abnormalities The hila consist of vessels, bronchi and lymph nodes. On a chest X-ray, abnormalities of these structures are represented by a change in position, size and/or density. Hilar enlargement may be unilateral or bilateral, symmetrical or asymmetrical. In combination with clinical information, each of these patterns is often helpful in reaching a diagnosis. Bilateral, symmetrical hilar enlargement should raise the suspicion of sarcoidosis, particularly if there is evidence of paratracheal enlargement, or lung parenchymal shadowing.

MS RN Salary, Wage Earnings, & Hourly Pay Scale According to the Bureau of Labor Statistics (BLS), Mississippi employed 27,590 registered nurses in May of 2013. The average annual RN salary in Mississippi was $56,530 at this time. This equates to about $26.41 per hour. This is significantly lower than the national average for this occupation, which was $65,470 in 2012. This may be due in part to a much lower cost of living.

- the appearance of multiple small nodules. Likewise the superimposition of multiple small nodules may produce a granular or ground-glass pattern. The pattern must be described as nodular or reticular. All the causes of consolidation should be considered when evaluating a chest X-ray

Evaluation of Solitary Thyroid Nodule Nodular disorders of the thyroid gland are relatively common among adults living in the United States, with an overall prevalence of approximately 4-7% in the general population. Most thyroid nodules are benign hyperplastic lesions, but 5-20% of thyroid nodules are true neoplasms. One of the major goals in the evaluation of the solitary thyroid nodule is the differentiation of hyperplasia from true neoplasms.

Thyroid ultrasound report showed thyroid gland enlarged. Diffuse heterogeneous echotexture noted. Suggest Diffuse heterogeneous echotexture is noted. The thyroid gland is mildly hypervascular on color Doppler images. There is a 1.2 cm isoechoic solid nodule in the right mid thyroid. It is not identified with certainty on previous ultrasound.Three smaller 5 mm to 9mm solid/hypoechoic solid/cystic nodules are noted in the right upper pole and mid thyroid.mpression: Moderately enlarged thyroid gland. Diffuse heterogenous echotexture. Thyroid gland is relatively stable in size. Several cysts/nodules in right and left thyroid lobe compatible with multinodular goiter.

Stenotrophomonas maltophilia Stenotrophomonas maltophilia. A gram-negative, motile, strictly anaerobic bacillus of the family Pseudomonadaceae. It may cause pneumonia, meningitis, endocarditis, conjunctivitis, wound infections, and infections related to the use of central venous catheters. Trimethoprim-sulfamethoxazole is used to treat infections with this organism.

Nuclear atypia Nuclear atypia refers to abnormal appearance of cell nuclei. It is a term used in cytopathology and histopathology. Atypical nuclei are often pleomorphic. Nuclear atypia can be seen in reactive changes, pre-neoplastic changes and malignancy.Severe nuclear atypia is, in most cases, considered an indicator of malignancy.uclear atypia can be seen in reactive changes, pre-neoplastic changes and malignancy.

- Heterotopic ossification is more common in the shoulder treated with hemiarthroplasty for humeral fracture. Severely injured soft tissues during the initial trauma and delayed surgical intervention are associated with higher rates of heterotopic ossification, though it typically is not clinically significant.

Gray matter heterotopia Symptomatic women with subependymal heterotopia typically present with partial epilepsy during the second decade of life; development and neurologic examinations up to that point are typically normal. Symptoms in men with subependymal heterotopia vary, depending on whether they have the X-linked or autosomal form.

Solitary Pulmonary Nodule A solitary pulmonary nodule is defined as a discrete lesion < 3 cm in diameter that is completely surrounded by lung parenchyma (ie, does not touch the hilum, mediastinum, or pleura) and is without associated atelectasis or pleural effusion. (Evaluation of a mediastinal mass is discussed elsewhere.)

The Scintigraphic Evaluation of Focal Nodular Hyperplasia with Tc-99m Sulfur Colloid Imaging Findings. A Tc-99m sulfur colloid exam (anterior planar image and SPECT images) demonstrated uptake in this lesion that was of a higher intensity than the rest of the liver (arrow on planar and on SPECT images). This finding proved that the lesion was benign, most likely focal nodular hyperplasia.

Subcortical band heterotopia This condition which primarily affects females, occurs when neurons migrate to an area of the brain where they are not supposed to be (heterotopia), and form abnormal areas that appear as band-like clusters of white tissue underneath the gray tissue of the cerebral cortex (subcortical), creating the appearance of a double cortex.

Congenital Disorders of the Brain Unlike subependymal hamartomas of tuberous sclerosis, which are isointense to myelinated white matter and can also be seen in a subependymal/periventricular location, heterotopias are isointense to gray matter and do not enhance. Subcortical heterotopias differ from periventricular heterotopias in that these nodular masses develop in the white matter as swirling, irregular, curvilinear areas of ectopic gray matter .
