“…There are no specific imaging techniques. However, as presented in our case, at US the lesion usually appears hypoechoic, clivated from the tendons, but MR can better delineate the lesion and define its relationship to the adjacent structures allowing a better pre-excisional planning [5]. Hwang et al [6] found that the smooth muscle and numerous vessels within vascular leiomyomas corresponded to hyperintense areas on T2-weighted MR images.…”

Vascular leiomyoma or angioleiomyoma is a rare benign solitary smooth muscle tumor that occurs mostly in the extremities. Most of these tumors are composed of venous vessels, but in some reports small arteries have been detected in the tumors.We present a rare case of a 60-year-old man with a subcutaneous vascular leiomyoma of the right knee. Clinical findings, ultrasound (US), magnetic resonance (MR), and histopathologic features are reported, and the literature is reviewed. The knowledge of specific imaging findings allows to include vascular leiomyoma in the differential diagnosis of lower extremity subcutaneous masses and to achieve an early accurate diagnosis.Sommario Il leiomioma vascolare e o angioleiomioma e è un raro tumore benigno, solitario che si localizza soprattutto a livello delle estremità. Gran parte di questi tumori sono composti di vasi venosi, ma in alcuni reprt sono state trovate delle piccole arterie.Presentiamo qui il caso di un uomo di 60 anni con un leiomioma vascolare sottocutaneo del ginocchio. Rivisitiamo qui la presentazione clinica, l'iconografia, le caratteristiche istopatologiche e la letteratura pertinente. La conoscenza delle caratteristiche specifiche di imaging permette di includere i leiomiomi vascolari nella diagnosi differenziale delle masse sottocutanee dolenti delle estremità e di ottenere una diagnosi precoce e mirata. ª

“…The first comprehensive review of this rare tumor was published by Stout in 1937 [2]. To the best of our knowledge, to date, only two cases of intra-articular angioleiomyoma in the knee joint have been reported [3,4]. An angioleiomyoma can clinically resemble a glomus tumor because of episodic focal hyperesthesia, temperature sensitivity, and severe tenderness.…”

“…In general, angioleiomyoma is painful and located in the subcutaneous fat and fascia [1,2], but its intra-articular occurrence is extremely rare. To the best of our knowledge, only two such cases have been reported in English, and gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) examination was performed in only one of them [3,4]. The atypical Gd-enhanced MRI image of our case compared with that of the more common angioleiomyoma arising in the subcutaneous fat may provide much preoperative information of this condition.…”

Intra-articular angioleiomyoma of the knee with an atypical finding on gadolinium-enhanced magnetic resonance imaging: a case report

IntroductionAngioleiomyoma is a benign smooth muscle tumor. It originates in the tunica media of veins. In general, it arises from the dermis, subcutaneous fat and fascia of lower extremities in middle-aged women. The case of intra-articular occurrence is very rare.Case presentationThis case report describes a 30-year-old Asian man with a 6-month history of recurrent pain localized in the lateral side of his left knee. Magnetic resonance imaging revealed an isolated intra-articular lesion. We performed a surgical excision of this lesion. On histological examination, the diagnosis of angioleiomyoma was confirmed. After the surgery, he recovered completely. Furthermore, no sign of recurrence was observed 1 year after surgery.ConclusionsIn this study, we report a rare case of intra-articular angioleiomyoma of the knee. The mass showed atypical findings on magnetic resonance imaging including gadolinium-enhanced imaging in comparison to previously reported intra-articular lesions. This intra-articular tumor is difficult to diagnose prior to surgery due to paucity of information.

Magnetic resonance imaging features of vascular leiomyoma of the ankle

et al. 2015

View full text Add to dashboard Cite

Vascular leiomyoma is a benign soft tissue tumour with a predilection for middle-aged women. It is most often seen in the extremities, particularly in the lower leg. The typical lesion is a small, slow-growing subcutaneous nodule. These tumours are often unexpected or preoperatively confused with other soft tissue tumours including low-grade sarcomas, leading to wide surgical excision. This may partly be due to the relatively few studies delineating the characteristic imaging features of this entity. Here, the imaging findings of a case of vascular leiomyoma in the ankle are presented. Literature review of the magnetic resonance imaging findings of published reports and series of vascular leiomyomas of the extremities is also performed.
