As early as the late 1800s, the appearance of hydatidiform moles have been likened to grapes. The bunch of grapes sign is an ultrasound finding of a heterogenous mass within the uterine cavity with multiple anechoic spaces.
The “bunch of grapes” is a radiological finding used to metaphorically describe the imaging appearance of a branch-duct type of intraductal papillary mucinous neoplasia (IPMN) of the pancreas. It refers to the presence of numerous clustered small cysts within the lesion, resembling a bunch of grapes (Fig.
Gross Pathology: Botryoid rhabdomyosarcoma (RMS) has a characteristic polypoid, grape-like gross appearance (botryoid = Greek for bunch of grapes). It is usually found in mucosa-lined hollow viscera such as urinary bladder, vagina, nasal cavity, nasopharynx, and the common bile duct.
The grape-skin sign is the radiographic or CT finding of a very thin-walled cavitary le- sion that develops in lung parenchyma pre- viously affected by consolidation or lung granulomas that have undergone central ca- seous necrosis [56].
Breast cysts are fluid-filled sacs inside the breast. They are usually noncancerous (benign). You may have one or multiple breast cysts. A breast cyst often feels like a grape or a water-filled balloon, but sometimes a breast cyst feels firm.
Lymph nodes can swell for a variety of reasons and are considered to be enlarged if they are bigger than 1.5 centimeters in diameter, or slightly larger than a pea. Typically, lymph nodes that are enlarged due to lymphoma are much bigger and can grow to be the size of a grape (or larger).
The grape cluster consists of peduncle, cap stems (also known as pedicels), rachis, and several berries. Depending on the variety, there is a big difference in the size and shape of the cluster, as well as in the shape, size, and color of the berries. Each berry “hangs” on the pedicel.
Abstract. As early as the late 1800s, the appearance of hydatidiform moles have been likened to grapes. The bunch of grapes sign is an ultrasound finding of a heterogenous mass within the uterine cavity with multiple anechoic spaces.
Anthracnose of grapes, caused by the fungus Elsinoe ampelina, is a serious disease of home-grown grapes. It is also commonly called bird's eye rot for the distinctive spots it causes on grape berries. The disease is most destructive in warm, wet seasons.
The bowl of grapes sign has been described in synovial sarcoma. It refers to the characteristic multilobulated lesion subdivided by multiple septa, forming large cystic foci with regions of hemorrhage.
Hydatiform mole is characterized by an overgrown villous trophoblast with cystic "swollen" villi. Macroscopically can be visible, the second trimester, as clusters of vesicles (similar to small grapes) developed from the transformation of chorionic villi.
Staphylococcus aureus, which usually forms grape-like clusters, has the ability to form regularly arranged cell packets.
Hydatidiform Mole
This rare tumor arises after the sperm and egg join and do not develop into a fetus; instead, tissue that resembles grape-like cysts forms. A hydatidiform mole may be complete or partial.
Follicles can also multiply to the point of appearing like a cluster of grapes (the other nickname for PCOS's appearance on ultrasound) within the ovarian stroma. It is these enlarged follicles that increase the volume of the ovary to more than 10 cm3.
Bunch of grapes sign refers to the imaging appearance of multiple cystic spaces or lesions and it has been described for multiple pathologies: bunches of grapes sign (hepatic abscess) bunch of grapes sign (botryoid rhabdomyosarcoma)
Bunch of grapes sign1 – refers to dilated bronchi lying in close approximation giving the appearance of clusters of thin walled cysts (Figs 2 and 3). Similar appearances have also been described in hydatidiform mole and intraductal papillary mucinous neoplasm.
Downy mildew, powdery mildew, grey mold, black rot and anthracnose are caused by fungi that attack the berries, reducing yield and quality. Crown gall is caused by a bacterium and can kill the plant. The first step in an effective pest management program is correct identification of the disease.
Disease symptoms
Tissues are generally susceptible to infection throughout the growing season. Diseased leaves appear whitish gray, dusty, or have a powdery white appearance. Petioles, cluster stems, and green shoots often look distorted or stunted. Berries can be infected until their sugar content reaches about 8%.
Grape diseases can be effectively managed through the combined use of culture, sanitation, resistance, and fungicide sprays. This integrated approach to disease control minimizes the reliance upon one type of control over the others and usually results in a high percentage of quality berries.
On an ultrasound cancerous tissue shows up black and dense tissue is still white, therefore cancers are easier to distinguish.
What is a molar pregnancy? A molar pregnancy occurs when an egg and sperm join incorrectly at fertilization and create a noncancerous tumor. The tumor looks like tiny water-filled sacs, similar to a cluster of grapes. The tumor can't support a developing embryo and the pregnancy ends.
The placenta grows normally with little or no growth of the fetal tissue. The placental tissue forms a mass in the uterus. On ultrasound, this mass often has a grape-like appearance, as it contains many small cysts. The chance of mole formation is higher in older women.
Stalk of an inflorescence or flower head. In grapes, the peduncle is the same as the cluster stem, meaning from the point of attachment to the shoot to the first lateral branch on the cluster.
A grape cluster formed by grape clusters. This cluster is called the Caleb cluster.
They are called alveoli - small, grape-like clusters inside your lungs. They play a key role in the exchange of gases into and out of your lungs and this role is essential in keeping us alive.
