A Case Report of Trigger Wrist Associated With Carpal Tunnel Syndrome Caused by an Intramuscular Lipoma

Lipoma, though one of the most common benign mesenchymal neoplasms, its presentation in hand is very rare. It can be located in various planes. Intramuscular lipomas are uncommon and usually occur in the proximal muscles of the extremities. Intramuscular lipoma of hand is extremely rare and only very few cases have been reported in the literature. Lipomas of hand may present with neurovascular deficit due to compression. We present here an unusual case of intramuscular lipoma of thenar region with no neurovascular deficit which was surgically excised under local anaesthesia with good cosmetic and functional outcome.

“…Intramuscular lipomas of the hand are very uncommon. 4,7 There are two subgroups of intramuscular lipomas; infiltrative type and well-circumscribed type. The term infiltrating lipoma has been used due to the infiltrative nature of the tumor in histological examination and represents the commonest type.…”

“…As a matter of fact, the ultrasound findings helped us to have a better understanding of the condition and eventually led us to proceed with surgical approach for the patient. MRI and CT scans are also useful in cases with large tumours, for both evaluation and operation planning [4–8]. …”

“…They may be associated with painful wrist triggering with associated carpal tunnel syndrome caused by an intramuscular lipoma of the lumbrical muscle [72,73]. They may be localized to the thenar [74][75][76][77][78], in the thenar or hypothenar muscles [79], to the abductor digiti minimi [80], to the extensors [81] and to the lexor hallucis brevis [82].…”

EDITORIALLipomas are the most common type of soft tissue tumor occurring in the subcutaneous tissue. Rarely, lipomas present in the deep soft tissue such as intermuscular, intramuscular, and parosteal sites. When they occur within a skeletal muscle they are called intramuscular lipomas. Intramuscular lipomas may involve both children and adults. They are benign, nontender, deep located, circumscribed but unencapsulated lesions. Intramuscular lipomas account less than 1% of all lipomas. Most are located within a single muscle (solitary), while cases involving two or more muscles are very rare. They present with typical histological features. They may be divided into the in iltrative, the well-circumscribed and the mixed type. Differential diagnosis of the in iltrative type from liposarcoma is very dif icult. Local recurrence may be evident if the surgical margin is not clear. They can occur in almost any anatomical site [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].Intramuscular lipomas of the head may involve the tongue, which is one of the most commonly involved sites [16][17][18][19][20][21][22][23][24] The chest wall [44,45] and the intercostal muscles [46] may also be involved. It may appear as a breast mass involving the pectoralis major [47][48][49] and may also involve the heart; involvement of the left ventricular myocardium, extending to the epicardial space; has also been reported [50]. The large muscles of the trunk may be involved such as the trapezius, the latissimus dorsi, the rhomboid major and the muscles of the anterior abdominal wall [14,51].
