| cystic mole | <gynaecology, oncology, tumour> A relatively rare mass or tumour that can form within the uterus at the beginning of a pregnancy. The cause of hydatidiform mole is unknown. Symptoms include vaginal bleeding, uterine growth, nausea and vomiting. Some hydatidiform moles may become malignant (cancerous) where they are referred to as a choriocarcinoma. Incidence: 1 in 1,500 births. (02 Jan 1998) |

| sessile hydatid | A vesicular nonpedunculated structure attached to the cephalic pole of the testis; a vestige of the cephalic end of the paramesonephric (mullerian) duct. Synonym: appendix testis, appendix of the testis, nonpedunculated hydatid, ovarium masculinum, sessile hydatid. (05 Mar 2000) |
| hydatid | <zoology> A membranous sac or bladder filled with a pellucid fluid, found in various parts of the bodies of animals, but unconnected with the tissues. It is usually formed by parasitic worms, especially. By larval tapeworms, as Echinococcus and Coenurus. See these words in the Vocabulary. <anatomy> Hydatid of Morgagni, one of the small pedunculated bodies found between the testicle and the head of the epididymis, and supposed to be a remnant of the Mullerian duct. Origin: Gr, a watery vesicle under the upper eyelid, fr. "ydwr, "ydatos, water: cf. F. Hydatide. Source: Websters Dictionary (01 Mar 1998) |
| hydatid cyst | A cyst formed in the liver, or, less frequently, elsewhere, by the larval stage of Echinococcus, chiefly in ruminants; two morphological forms caused by Echinococcus granulosus are found in humans: the unilocular hydatid cyst and the osseous hydatid cyst; a third form in humans is the alveolar hydatid cyst, caused by Echinococcus multilocularis. Synonym: echinococcus cyst, hydatid. (05 Mar 2000) |
| hydatid cyst of morgagni | <radiology> Paraovarian cyst near fimbria or broad ligament, serous fluid, no clinical significance, wolffian duct remnant (probably) (12 Dec 1998) |
| hydatid disease | <infectious disease> A tissue infection by the larval stage of the Echinococcus granulosus worm. This disease is common in South America, the Middle East, Asia and Africa. Sporadic cases have been reported in the us. Infection occurs after ingestion of eggs in infected dog faeces. The infection is carried to the liver where cysts form. Cysts may also form in the lungs, bone, brain, kidney, muscles and spleen. Symptoms include abdominal pain, itching, cough, haemoptysis, chest pain and fever. Treatment includes the surgical removal of cysts from the tissue. (27 Sep 1997) |
| hydatid fremitus | The peculiar trembling or vibratory sensation felt on palpation of a hydatid cyst. Synonym: Blatin's syndrome, hydatid fremitus. (05 Mar 2000) |
| hydatidiform mole | <gynaecology, oncology, tumour> A relatively rare mass or tumour that can form within the uterus at the beginning of a pregnancy. The cause of hydatidiform mole is unknown.

| hydatidiform mole, invasive | A tumour or tumour-like process invading the myometrium, and characterised by trophoblastic hyperplasia and persistence of placental villous structures. It commonly results from complete hydatidiform mole but may do so from partial hydatidiform mole. Invasive mole may metastasize but it does not exhibit the progression of a true cancer, and it may regress spontaneously. (holland et al., cancer medicine, 3d ed, p1691) (12 Dec 1998) |
| hydatid polyp | A pedunculated cyst. Synonym: hydatid polyp. (05 Mar 2000) |

| hydatid rash | A toxic eruption occasionally following the rupture of a hydatid cyst. (05 Mar 2000) |
| hydatid resonance | A peculiar vibratile resonance heard on auscultatory percussion over a hydatid cyst. (05 Mar 2000) |
| hydatid sand | The scoleces of Echinococcus tapeworms in the fluid within a primary or daughter hydatid cyst. (05 Mar 2000) |
| hydatid thrill | The peculiar trembling or vibratory sensation felt on palpation of a hydatid cyst. Synonym: Blatin's syndrome, hydatid fremitus. (05 Mar 2000) |
