| benign inoculation reticulosis | <disease> A self-limiting bacterial infection of the regional lymph nodes (lymphadenitis) caused by afipia felis, a gram-negative bacterium recently identified as bartonella henselae. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom. It results in tender and enlarged lymph glands above the site of injury. A chronic benign adenopathy, especially in children and young adults, commonly associated with a recent cat scratch or bite and caused by bacteria including Bartonella henselae and Alipia felis; the lymphadenopathy usually resolves spontaneously within a period of several months, but complications involving central nervous system, liver, spleen, lung, and skin have been seen. Synonym: benign inoculation lymphoreticulosis, benign inoculation reticulosis, cat-scratch fever, regional granulomatous lymphadenitis. (05 Mar 2000) |

| midline malignant reticulosis granuloma | Destruction of the nasal septum, hard palate, lateral nasal walls, paranasal sinuses, skin of the face, orbit and nasopharynx by an inflammatory infiltrate with atypical lymphocytic and histiocytic cells; presumably a form of lymphoma in most cases. An obsolete term for polymorphic reticulosis. Synonym: granuloma gangrenescens, malignant granuloma, midline malignant reticulosis granuloma. (05 Mar 2000) |
| polymorphic reticulosis | A necrotizing lymphoproliferative lesion with a predilection for the upper respiratory tract. Previously called lethal midline granuloma or malignant midline reticulosis. Treatment is irradiation. (05 Mar 2000) |

| lipomelanic reticulosis | Enlargement of lymph nodes, with proliferation of pale-staining interdigitating reticulum cells and macrophages containing fat and melanin; secondary to various forms of dermatitis. Synonym: dermatopathic lymphadenitis, lipomelanic reticulosis. (05 Mar 2000) |
| adrenal medullary imaging | <investigation, radiology> A nuclear scan that images the adrenal glands after a radioactive tracer is injected into the bloodstream. This test is useful in detecting a pheochromocytoma, particularly if it not within the adrenal gland. (27 Sep 1997) |
| anterior medullary velum | The thin layer of white matter stretching between the two superior cerebellar peduncles, forming the roof of the superior recess of the fourth ventricle. Synonym: velum medullare superius, anterior medullary velum, Vieussens' valve. (05 Mar 2000) |
| carcinoma, medullary | A carcinoma composed mainly of epithelial elements with little or no stroma. Medullary carcinomas of the breast constitute 5%-7% of all mammary carcinomas; medullary carcinomas of the thyroid comprise 3%-10% of all thyroid malignancies. (12 Dec 1998) |
| medial medullary lamina of corpus striatum | A fibre layer separating the medial and lateral segments of the globus pallidus. Synonym: lamina medullaris medialis corporis striati. (05 Mar 2000) |
| medullary | <anatomy> Pertaining to the marrow or to any medulla, resembling marrow. Origin: L. Medullaris (18 Nov 1997) |

| medullary bone | Areas of bone formation present in the marrow spaces of the long bone's of birds, which serve as a readily mobilised source of calcium for shell formation. (05 Mar 2000) |
