Abstract

Purpose

This retrospective magnetic resonance imaging investigation aimed to obtain information related to the anatomy of the massa intermedia (MI) in an adult population.

Methods

The work conducted on MRI views of 1058 (539 males and 519 females) healthy adult samples aged with 48.93 ± 17.63 years. Initially, the presence or absence of MI was noted, and then if present, its numbers and location in the third ventricle were recorded. Its horizontal (HDMI) and vertical (VDMI) diameters were measured on MRI views, while the cross-sectional area (CSAMI) was calculated using its diameters.

Results

MI was missing in 2.6% (27 cases) of 1058 adult samples. Six subjects (0.6%) had a double MI. HDMI, VDMI and CSAMI were measured as 4.83 ± 1.01 mm, 4.86 ± 0.98 mm, and 19.11 ± 7.23 mm², respectively. MI size did not show a significant alteration from 19 up to 49 years, but then its size distinctly decreased between 50 and 60 years. After age 60, MI dimension did not display an important change. MI was settled in the antero-superior quadrant in 929 cases (90.63% of 1025 subjects), in the postero-superior quadrant in 22 cases (2.15%), in the antero-inferior quadrant in 32 cases (3.12%), in the postero-inferior quadrant in 8 cases (0.78%), and in the central part in 34 cases (3.32%).

Conclusions

The size, position and incidence of MI were not affected by sex, and its position and incidence were not affected by adult age periods. In adults, MI size demonstrated a significant decrease in the middle age.

成人中浆肿：发病率、尺寸、位置和临床重要性

目的这项回顾性磁共振成像调查旨在获取成人群体中中块（MI）解剖结构的相关信息。方法对 1058 例（男 539 例，女 519 例）年龄为 48.93 ± 17.63 岁的健康成人样本进行磁共振成像检查。首先记录是否存在心肌缺血，如果存在，则记录其数量和在第三脑室的位置。在核磁共振成像视图上测量其水平（HDMI）和垂直（VDMI）直径，并根据其直径计算横截面积（CSAMI）。6名受试者（0.6%）有双重MI。测得的 HDMI、VDMI 和 CSAMI 分别为 4.83 ± 1.01 mm、4.86 ± 0.98 mm 和 19.11 ± 7.23 mm2。心肌尺寸在 19 至 49 岁期间没有明显变化，但在 50 至 60 岁期间明显缩小。60 岁以后，心肌梗死的大小没有明显变化。有 929 例（占 1025 例受试者的 90.63%）MI 位于前上象限，22 例（2.15%）位于后上象限，32 例（3.12%）位于前内象限，8 例（0.结论 MI的大小、位置和发病率不受性别影响，其位置和发病率也不受成人年龄段的影响。在成年人中，心肌梗死的大小在中年时明显减小。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
