What is Racemose neurocysticercosis?
Racemose neurocysticercosis refers to the ‘aberrant proliferating cestode larvae” presenting as multiple, non-capsulated cystic membranes that bud exogenously giving a multilocular cystic appearance resembling a ‘bunch of grapes’.
What is NCC in radiology?
On the basis of radiologic findings, neurocysticercosis is divided into five stages: noncystic, vesicular, colloidal vesicular, granular nodular, and calcified nodular (14). Noncystic neurocysticercosis (active) is asymptomatic with negative imaging findings.
What is NAA brain Spectroscopy?
N-acetylaspartate (NAA) is one of the more important compounds assessed on MR spectroscopy, and resonates at 2.0 ppm chemical shift (its concentration in healthy adults is 8-10 mM) 1. The synthesis of NAA, adenosine diphosphate-dependent, occurs in the neuronal mitochondria 2.
How is Tuberculoma treated?
The usual treatment is:
- 2 antibiotics (isoniazid and rifampicin) for 6 months.
- 2 additional antibiotics (pyrazinamide and ethambutol) for the first 2 months of the 6-month treatment period.
What is MRI NAA?
What is NAA peak?
N-acetyl aspartate (NAA) N-acetyl aspartate (NAA) shows the largest peak of the spectra at 2.02 ppm as a singlet peak and another quadruplet peak at 2.5 ppm. NAA peak also obtains contributions from N-acetyl aspartyl glutamate (NAAG), glycoproteins, and amino acid residues in peptides.
What is the clinical presentation of racemose cysts of the brain?
The clinical presentation of racemose cysts is pleomorphic, and is quite different from parenchymal cysticercosis. The clinical diagnosis of racemose cysts is quite challenging, with neuroimaging being the mainstay. However, the advent of newer brain imaging modalities has made a more accurate diagnosis possible.
What is the pathophysiology of racemose neurocysticercosis?
Racemose neurocysticercosis refers to the ‘aberrant proliferating cestode larvae” presenting as multiple, non-capsulated cystic membranes that bud exogenously giving a multilocular cystic appearance resembling a ‘bunch of grapes’.
What is the difference between parenchymal and racemose cysts?
In the brain it occurs in two forms: parenchymal and extraparenchymal or racemose cysts. The clinical presentation of racemose cysts is pleomorphic, and is quite different from parenchymal cysticercosis. The clinical diagnosis of racemose cysts is quite challenging, with neuroimaging being the mainstay.
How are racemose ovarian cysts diagnosed?
The investigation of choice for the diagnosis of racemose cysts is MRI. Due to its multiform manifestation, less frequent occurrence, and chances of false negativity on imaging, a high index of suspicion for the diagnosis is mandated, especially in endemic areas.
