| agenesis | <embryology> A condition in which a part of the body (such as an organ or a tissue) does not completely develop or fails to develop at all. (09 Oct 1997) |
|---|---|
| agenesis of corpus callosum | <radiology> Defect in dorsal portion of lamina reuniens, occurs about 10th - 12th week of gestation, may be complete or partial CT findings: parallel lateral ventricles, occipital horns dilated, deep falx, frontal horns C-shaped on coronal view associated with, Dandy-Walker cyst, encephalocele, Arnold-Chiari malformation, CNS lipoma (12 Dec 1998) |
| renal agenesis | <radiology> Associated with, duplicated vagina and/or uterus (mullerian duct anomaly), seminal vesicle cysts (12 Dec 1998) |
| gonadal agenesis | Congenital absence of essentially all gonadal tissue; the external genitalia and genital ducts are female, but if interstitial cells of Leydig are present, the external genitalia are commonly ambiguous and the genital ducts are female. See: gonadal dysgenesis. Compare: Klinefelter's syndrome, Turner's syndrome. Synonym: gonadal agenesis. (05 Mar 2000) |
| sacral agenesis | <radiology> Agenesis or hypoplasia of sacrum, part of caudal-regression syndrome, associated with maternal diabetes, with or without inherited, possible features: absent lower extremities, bladder/bowel impairment (12 Dec 1998) |
| thymic agenesis | The absence of the thymus, which may be associated with parathyroid agenesis in DiGeorge syndrome. (05 Mar 2000) |
| malignant mixed mullerian tumour | A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. Synonym: malignant mixed mullerian tumour. (05 Mar 2000) |
| persistent mullerian duct syndrome | <syndrome> Familial disorder with presence of fallopian tube, uterus, and testis in a male. Deficient mullerian inhibitory substance secondary to Sertoli cell defect. Synonym: hernia uteri inguinale. (05 Mar 2000) |
| mixed tumour, mullerian | A tumour, basically a carcinoma with a single sarcoma such as leiomyosarcoma or angiosarcoma or multiple sarcomas of uterine origin. The role of oestrogen has been postulated as a possible aetiological factor in this tumour. (holland et al., cancer medicine, 3d ed, p1703) (12 Dec 1998) |
| mullerian | <anatomy> Of, pertaining to, or discovered by, Johannes Muller. <anatomy> Mullerian ducts, the sustentacular or connective-tissue fibres which form the framework of the retina. Source: Websters Dictionary (01 Mar 1998) |
| mullerian adenosarcoma | <tumour> A tumour of the uterus or ovaries, of low grade malignancy, characterised by benign appearing glands and a sarcomatous stroma. (05 Mar 2000) |
| mullerian duct | <radiology> FEMALE, fallopian tubes, uterus, vagina Male, appendix testis, prostatic utricle anomalies: mullerian agenesis most likely to be absent uterus and vagina, incomplete fusion most likely to be bicornuate/double uterus, double vagina, both associated with renal agenesis Cf: wolffian duct (12 Dec 1998) |
| mullerian ducts | Two ducts of the embryo which empty into the cloaca, and which in the female develop into vagina, uterus and oviducts; in the male they disappear except for the vestigial vagina masculina and the appendix testis. (12 Dec 1998) |
| mullerian inhibiting factor | A 535 amino acid glycoprotein secreted by the Sertoli cells of the testis. It is related to inhibin. Synonym: mullerian inhibiting factor. (05 Mar 2000) |
| mullerian inhibiting substance | A 535 amino acid glycoprotein secreted by the Sertoli cells of the testis. It is related to inhibin. Synonym: mullerian inhibiting factor. (05 Mar 2000) |
