Humeral head cysts are not uncommon in individuals with rotator cuff disorders. The cysts are usually considered an indicator of rotator cuff pathologies; however, they may have different meanings in different regions.
To determine the frequency of cysts within and adjacent to the lesser tuberosity and the relationship between these cysts and subscapularis, supraspinatus, and long head of the biceps tendon (LHBT) disorders.
We retrospectively reviewed 760 consecutive shoulder magnetic resonance imaging (MRI) examinations. Among these MRIs, we selected a group of patients with cysts located around the lesser tuberosity. The study population was also divided into two subgroups, patients with cysts within the lesser tuberosity and those with cysts adjacent to the lesser tuberosity. In addition to the number and size of cysts, the MRI appearance of the tendons was evaluated.
Eighty-one (10.7%) patients had cysts within and/or adjacent to the lesser tuberosity, 34 (42%) patients had cysts within the lesser tuberosity, and 47 (58%) patients had cysts adjacent to it. LHBT and subscapularis tendon disorders were significantly related to more than one cyst. In a univariate analysis, cysts within the lesser tuberosity were significantly associated with LHBT and subscapularis tendon disorders; however, multivariate analyses showed that only LHBT disorders were significantly associated with cysts within the lesser tuberosity.
Cysts within the lesser tuberosity were less common than cysts adjacent to it. LHBT and subscapularis tendon disorders were more frequently found in patients with more than one cyst within and/or adjacent to the lesser tuberosity. In addition, cysts within the lesser tuberosity were associated with LHBT disorders.
肱骨头囊肿在肩袖疾病患者中并不少见。这些囊肿通常被认为是肩袖病变的一个指标；然而，它们在不同区域可能有不同的意义。
确定小结节内及相邻部位囊肿的发生率，以及这些囊肿与肩胛下肌、冈上肌和肱二头肌长头肌腱（LHBT）疾病之间的关系。
我们回顾性分析了760例连续的肩部磁共振成像（MRI）检查。在这些MRI检查中，我们选择了一组小结节周围有囊肿的患者。研究人群也分为两个亚组，小结节内有囊肿的患者和小结节相邻部位有囊肿的患者。除了囊肿的数量和大小，还对肌腱的MRI表现进行了评估。
81例（10.7%）患者小结节内及/或相邻部位有囊肿，34例（42%）患者小结节内有囊肿，47例（58%）患者小结节相邻部位有囊肿。LHBT和肩胛下肌腱疾病与多个囊肿显著相关。在单因素分析中，小结节内的囊肿与LHBT和肩胛下肌腱疾病显著相关；然而，多因素分析显示，只有LHBT疾病与小结节内的囊肿显著相关。
小结节内的囊肿比相邻部位的囊肿少见。在小结节内及/或相邻部位有多个囊肿的患者中，LHBT和肩胛下肌腱疾病更为常见。此外，小结节内的囊肿与LHBT疾病有关。
