Branchial pouch sinus tract from the pyriform
fossa causing acute suppurative thyroiditis, neck abscess, or both: CT appearance and the use of air as a contrast agent.
5d): strongly pyriform
, pars cephalica strongly prolonged and elevated, base colour light brown, eye region chestnut brown.
Amorphous, tapering, and pyriform
shapes are also abnormal.
Structures of the limbic system include all cortical and subcortical structures that form the border of the lateral ventricles: the hippocampal formation, the dentate gyrus, the pyriform
cortex of the anterior hippocampal gyrus and the cingulate gyrus.
Nauplius is a tiny Pyriform
or pear-shaped tiny body possessing three pairs of appendages.
Perhaps the most biologically rooted neural-net model to date is the brainchild of neurobiologist Gary Lynch, computer scientist Richard Granger and their colleagues at UCI, who have built a simulation of one layer of neurons, called layer II, in the rat's pyriform
, or olfactory, cortex -- a brain area that has been linked to the sorting and storage of smells.
The aryepiglottic folds are thin walls of tissue that extend from the posterior upper larynx to the epiglottis, and these form the medial borders of the pyriform
sinuses, which may be elucidated on a swallow study (not shown here).
The mass was removed without difficulty via electrocautery, and no evidence of an associated sinus tract was found after careful probing of the underlying pharyngeal wall, tonsillar fossa, and pyriform
Of these, pyriform
fossa SCC is common, particularly amongst smokers.
, dull, granulated, covered with dense short hairs; occipital carina complete; ocelli distinct; holotype with POL = 2; OL = 4; OOL = 10; OPL = 4; TL = 14; eyes very small, approximately 0.
fruit body is perched near the apex and the wings are membranous, without obvious striation or venation, except for a median set of 3-5 longitudinal veins extending from the pedicel to the base of the fruit body, each paralleled by a thinner vein to the inside.
Mild to moderate lateral pharyngeal oedema and ecchymosis of the pyriform
sinus and aryepiglottic fold have been noted in a significant number of MMA patients.
