“…As a potential target, muscle tissue remains infrequent for metastasis because of its unique mechanical and metabolic qualities. An unfavorable pH, the presence of protease inhibitors, and contractility of muscles leading to turbulent blood flow are all factors attributed to the relative rarity of skeletal muscle metastasis in a malignant process …”

A 13-year-old spayed female German shepherd dog was presented for acute onset of lethargy, anorexia, and disseminated erythematous skin lesions. Thoracic radiographs and abdominal ultrasonographic findings were consistent with metastatic hemangiosarcoma. Multiple, ill-defined, irregularly shaped hypoechoic nodules were also detected within the thoracic and abdominal wall. Hemangiosarcoma metastases to the skeletal muscle were confirmed based on histopathological examination. Multivisceral involvement was also confirmed by necropsy. Metastatic neoplasia should be considered as a differential diagnosis for dogs with ill-defined, irregular, hypoechoic, intramuscular nodules.

“…The various factors attributed to the relative rarity of skeletal muscle metastasis in a malignant process include: (1) contractility of muscles leading to turbulent blood flow; (2) unfavorable pH; and (3) the presence of protease inhibitors [2] . The peer-reviewed literature on psoas muscle metastasis in the context of carcinoma cervix is limited, primarily emphasizing the diagnostic dilemma in differentiating this entity mainly from post-irradiation abscess and sarcoma [1][2][3][4][5][6] . The challenges and refractoriness of the pain related to malignant psoas syndrome arising from a background of cervical carcinoma has been another aspect that has been described in the form of case reports [7][8][9] with one report describing a good outcome with combined surgical excision and adjuvant radiation therapy.…”

“…Skeletal muscle metastasis from cervical carcinoma is a rare event (less than 1% incidence), the most common being the involvement of the psoas muscle. There is a lack of characteristic diagnostic imaging features on conventional imaging modalities which have been nonspecific in this domain and the differential diagnosis includes sarcoma, hematoma, and abscess [1][2][3][4][5][6] . Thus the features of this relatively unusual but important entity on newer non-invasive molecular imaging modalities [e.g., positron emission tomography/computed tomography (PET/CT) and diffusion-weighted imaging of magnetic resonance imaging (DWI-MRI)] need critical exploration and comparison.…”

Psoas muscle metastasis, though rare, is the commonest site of skeletal muscle involvement in cervical carcinoma. The appropriate clinical management of this condition, particularly of the pain related to malignant psoas syndrome, is still evolving and the diagnostic features on conventional morphological imaging modalities are often non specific, with the differential diagnosis lying between sarcoma, hematoma, and abscess. In this report, a comparison of various morphofunctional imaging modalities was made. Fluorodeoxyglucose-positron emission tomography (FDG-PET)/computed tomography (CT) was the first to suspect disease involvement of the psoas muscle, demonstrating intense FDG uptake (compared with the contralateral muscle), while ultrasound showed heterogeneous echotexture, and magnetic resonance imaging (MRI) showed subtle altered signal intensity in the right psoas muscle. Both anatomical imaging modalities and non contrast CT of the PET-CT examination demonstrated a bulky psoas muscle, without any focal abnormality. On diffusion-weighted imaging of MRI (DWI-MRI), restricted diffusion of the involved muscle was an important observation. The psoas muscle metastatic involvement was proven histopathologically. Thus, enhanced glucose metabolism and restricted diffusion in the newer non-invasive molecular imaging modalities (e.g., PET/CT and DWI-MRI) could serve as valuable adjunctive parameters in diagnosing this entity in the absence of a focal abnormality in the anatomical modalities. In the treatment response monitoring scenario, FDG-PET/CT demonstrated near complete resolution following administration of 3 cycles of systemic chemotherapy and local external radiotherapy.

“…Since 2008, only 10 cases with muscle metastasis from cervical cancer have been reported in literature (2). In the case described by Kalra et al (3) and Kamal et al, involvement of iliopsoas muscle secondary to cervical cancer was diagnosed several years after radiotherapy treatment of the primary tumor (3,4). The occurrence of coexistent cervical cancer and involvement of iliopsoas muscle at the time of diagnosis of the cancer has not been reported.…”

Introduction: Isolated metastasis of cervical carcinoma to iliopsoas region might be infrequent and its occurrence is a diagnostic challenge. The aim of this study was to report on a case of iliopsoas muscle metastasis from cervical carcinoma. Case Presentation: A 52-year-old multiparous females complaining about post menopause bleeding was referred to the researcher's oncology department. Gynecological examination revealed cervical mass with involved parameters and biopsy confirming squamous cell carcinoma. In addition, the patient had a large cystic mass on the lateral side of pelvic area and abdomen. Investigations detected solid ovarian mass associated with a rise of tumor marker CA-125 and CEA levels. Magnetic resonance imaging (MRI) and CT scan reports suggested possible hematoma in iliopsoas muscle. Imaging-guided biopsy detected metastatic squamous cell carcinoma in iliopsoas muscle mass. Based on diagnosis of advance stage cervical cancer, the patient received chemotherapy following adjuvant radiation therapy. Conclusions: Metastasis of squamous cell carcinoma of the cervix to iliopsoas muscle is considered as a rare event. It is recommended to keep this unusual manifestation in mind.
