As early as the late 1800s, the appearance of hydatidiform moles have been likened to grapes. The ultrasound bunch of grapes sign is a uterine heterogenous mass with multiple anechoic spaces. Treatment includes surgical removal and continued surveillance of human chorionic gonadotropin levels.
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.
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.
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.
It represents an abnormal proliferation of trophoblastic tissue, with no fetal formation, just hydropic villi. These abnormal villi seen in ultrasound are compared to a "bunch of grapes," a classic description of this disease.
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.
Grapelike leiomyomas of the uterus are histologi- cally benign smooth muscle tumors with extensive con- tiguous extrauterine spread of multiple nodules resem- bling a bunch of grapes. ' Only two cases have been reported previously, and both were treated by hysterec- tomy because of the alarming operative appearance.
The length of grapevine shoots and canes is partitioned, alternately, into nodes and internodes (fig. 2.1). Nodes are the thickened sections that have buds from which new shoots may arise. Internodes are the smaller-diameter sections between each node.
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.
The bunch of grapes sign, a.k.a. cluster of grapes sign, is a characteristic imaging finding on CT seen in bronchiectasis. Closely apposed dilated bronchi may look like multiple adjacent thin walled cysts which mimic the appearance of a bunch of grapes.
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%.
A grape mutation occurs when a variety reacts to changes in its environment, generally to protect itself against frost, rot or other hazards. Two popular examples of grape mutations are Pinot Gris and Pinot Blanc, which are mutations of Pinot Noir.
Grapes are typically an ellipsoid shape resembling a prolate spheroid.
On an ultrasound cancerous tissue shows up black and dense tissue is still white, therefore cancers are easier to distinguish.
For example, most waves pass through a fluid-filled cyst and send back very few or faint echoes, which look black on the display screen. On the other hand, waves will bounce off a solid tumor, creating a pattern of echoes that the computer will interpret as a lighter-colored image.
Ultrasound. Lipomas appear as soft variably echogenic masses, commonly encountered on ultrasound. If encapsulated, the capsule may be difficult to identify on ultrasound 5.
Grape powdery mildew is caused by the fungus Uncinula necator. This fungus has a narrow host range attacking only grape plants and a few related species. It is the most common and widespread disease of grapevines in the B.C. Interior. Popular wine grape varieties vary in susceptibility to powdery mildew.
Bacterial blight of grapevine is a serious, chronic and systemic disease of grapevine that affects commercially important cultivars. It is caused by the bacterium Xylophilus ampelinus which survives in the vascular tissues of infected plants.
What is causing small bumps on the leaves of my grapes? Answer: This is the result of the insect grape phylloxera.
Hedging is a technique used to remove excess primary and lateral shoot growth from the top of the vine and sometimes sides of the canopy (Goldammer, 2018). Grapevines need only 15 leaves per shoot to fully mature the crop. Excess leaves above and beyond this number only divert resources from the ripening fruit.
Sarcoma botryoides, also known as botryoid rhabdomyosarcoma, is a rare subtype of a highly malignant tumor called embryonal rhabdomyosarcoma. The name botryoides originates from the Greek root bótry(s), which refers to the appearance of “a bunch of grapes”.
Tumor sizes are often measured in centimeters (cm) or inches. Common food items that can be used to show tumor size in cm include: a pea (1 cm), a peanut (2 cm), a grape (3 cm), a walnut (4 cm), a lime (5 cm or 2 inches), an egg (6 cm), a peach (7 cm), and a grapefruit (10 cm or 4 inches).
Uterine fibroids are a common type of noncancerous tumor that can grow in and on your uterus. Not all fibroids cause symptoms, but when they do, symptoms can include heavy menstrual bleeding, back pain, frequent urination and pain during sex.
However, it is possible for a person without any known or theoretical risk factors to develop fibroids. Fibroids can range in size from microscopic to the size of a grapefruit or even larger. The majority of fibroids are small and do not cause any symptoms at all.
