Differential Diagnosis for Isolated Shoulder Numbness over Subacrominal Bursa

Single Most Likely Diagnosis

  • Subacromial Bursitis: This condition is characterized by inflammation of the subacromial bursa, which can cause numbness, pain, and limited mobility in the shoulder region. The symptoms can be exacerbated by movements that increase pressure on the bursa, such as lifting or reaching.

Other Likely Diagnoses

  • Rotator Cuff Tendinitis: Inflammation of the tendons surrounding the shoulder joint can lead to pain and numbness, especially if the tendons are impinged upon by the acromion. This condition is common in individuals who perform repetitive overhead activities.
  • Suprascapular Neuropathy: Compression or injury to the suprascapular nerve can cause numbness, pain, and weakness in the shoulder region. This nerve supplies the supraspinatus and infraspinatus muscles, which are crucial for shoulder stability and movement.
  • Cervical Radiculopathy: Although less common for isolated shoulder numbness, cervical radiculopathy (nerve root compression in the neck) can cause referred pain and numbness to the shoulder area, especially if the C5 or C6 nerve roots are involved.

Do Not Miss Diagnoses

  • Thoracic Outlet Syndrome (TOS): A condition where the nerves and/or blood vessels that pass into the thoracic outlet (the space between your collarbone and first rib) become compressed. This can lead to numbness, pain, and weakness in the shoulder and arm. Missing TOS could lead to prolonged suffering and potential long-term nerve damage.
  • Pancoast Tumor: A rare type of lung cancer located at the top of the lung that can invade nearby structures, including nerves, leading to shoulder pain and numbness. Early detection is crucial for treatment and prognosis.

Rare Diagnoses

  • Brachial Plexitis (Neuralgic Amyotrophy): An inflammatory condition that affects the brachial plexus, leading to severe pain and numbness in the shoulder and arm. It is relatively rare and can be idiopathic or associated with autoimmune conditions.
  • Sickle Cell Disease Crisis: In patients with sickle cell disease, a crisis can lead to vaso-occlusive episodes that might cause numbness and pain in various parts of the body, including the shoulder, due to ischemia. This would be considered in patients with a known history of the disease.
