Nucl Med Mol Imaging 2024; 58:140-146. [PMID: 38633285 PMCID: PMC11018563 DOI: 10.1007/s13139-024-00846-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/03/2023] [Accepted: 01/29/2024] [Indexed: 04/19/2024] Open
Abstract
Fibromatoses are a heterogeneous group of benign proliferating fibroblasts and myofibroblasts which have a high predilection for recurrence and local invasion, especially deep fibromatoses or desmoid fibromatosis. 18F-FDG PET/CT, the workhorse of oncological imaging in nuclear medicine, can be employed to figure out the nature and aggressiveness of the lesions and various sites of involvement and to monitor treatment response to systemic therapies like tyrosine kinase inhibitors in case of deep or desmoid fibromatoses which is shown in the current research work.

Abstract
Fibromatosis or desmoid fibromatosis is a rare benign neoplasm and develops commonly in the abdominal wall, abdominal cavity, or extra-abdominal sites. The mainstay of treatment is surgery. Chemotherapy and radiotherapy are preferred in cases of inoperable/relapse or a multifocal disease. Hereby, we report a case of fibromatosis arising in the left popliteal fossa, proven by histopathology and immunohistochemistry. Local excision of the mass was performed. The patient was asymptomatic for 6 months, after which she complained of difficulty in walking. Clinical evaluation elicited recurrence in the surgical bed. In spite of the surgical excision with tumor-free margins, recurrence was seen within a span of 6 months. 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) was done to rule out multifocal disease and to define the extent of relapse. Although magnetic resonance imaging provides an excellent soft-tissue resolution to delineate the disease, 18F-FDG PET/CT is an important and supplementary tool which aids in the management of fibromatosis.

Abstract
Collagenous fibroma arising from the subacromial region is extremely rare. It is important to distinguish collagenous fibroma from other fibrous tumors including desmoid tumors, to differentiate between the prognoses and management strategies, including surgical treatment. The present case report describes the case of a 42-year-old man with a collagenous fibroma of the subacromial region. He received a follow-up examination following treatment for osteosarcoma. Positron emission tomography (PET) scans used to assess for metastatic lesions indicated uptake in his left shoulder. The maximum standardized uptake value was 2.4. Magnetic resonance imaging demonstrated iso-intensity to muscle on T1-weighted images and iso-intensity with slightly high intensity on T2-weighted images. Post-contrast fat-suppressed magnetic resonance images indicated slightly heterogeneous enhancement of the lesion. There were no notable results from X-rays, bone scintigraphy and thallium-201 scintigraphy. Histological examination revealed collagenous fibroma. To the best of our knowledge, the present case is only the second incidence of collagenous fibroma arising from the subacromial region, and the first description of thallium-201 scintigraphy and PET scans in collagenous fibroma. The multimodal radiological data of this case may be useful for assisting in the differentiation of fibrous tumor types, including collagenous fibroma.

Abstract
Fibromatoses are soft tissue tumors composed of fibroblasts which commonly appear in the muscular aponeurosis of the abdomen. Mammary fibromatoses occur in only 0.2% of breast neoplasms and have been reported in association with prior breast augmentation and Gardner's syndrome. Multiple imaging modalities have been used to characterize the appearance of breast fibromatosis; however, it remains a tissue diagnosis given the variability both within and across modalities. We present the case of a 25-year-old female with a history of palpable breast mass who was evaluated with ultrasound, diagnostic mammography, MRI, and CT. Ultrasound-guided biopsy revealed fibromatosis, and MRI ultimately revealed that the mass was arising from the pectoralis major muscle and extensively involved the chest wall.

Abstract
Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy. The desmoid tumor is a rare benign tumor that should be considered in the differential diagnosis of malignant local tumor recurrence after breast cancer operation. Biopsy was required for accurate diagnosis and wide local excision was its appropriate surgical management.

Abstract
Extra abdominal desmoid fibromatosis is a complex condition with many recognised treatments including active observation, hormonal therapy, chemotherapy, radiotherapy and surgical resection. There is large variation in the natural history of individual desmoid tumours, with some cases progressing aggressively and others regressing spontaneously when observed alone. This combined with an absence of accurate clinical predictors of a desmoid tumour's behaviour has led to difficulties in identifying which patients would benefit most from aggressive treatment, and which could be adequately managed with a policy of active observation alone. This review explores the aetiology and common presentation of extra-abdominal desmoid fibromatosis including the condition's histopathological, clinical and radiological characteristics. The current evidence for potential predictors of desmoid tumour behaviour is also reviewed, along with the indications and evidence for the multitude of treatments available. We also summarise the published guidelines that are currently available for oncologists and surgeons managing extra-abdominal desmoid fibromatosis, and highlight some of the unanswered questions that need to be addressed to optimise the management of this condition.

Abstract
A spindle cell lipoma (SCL) is a relatively common tumor that can be challenging to the radiologist, pathologist, or surgeon to diagnose, particularly when internal fat content is scant or absent. Although these lesions may be found at various locations, the typical presentation for this lesion is a well-circumscribed and non-aggressive subcutaneous mass in the posterior neck presenting in a middle-aged to elderly man. In this article, the typical and atypical imaging characteristics of a spindle cell lipoma (SCL) will be reviewed. Knowledge of the common imaging and pathologic features of SCLs can help suggest the diagnosis and guide patient management.

Abstract
UNLABELLED Malignant primary chest wall neoplasms (MCWN) are uncommon. Although benign chest wall neoplasms are most commonly asymptomatic, MCWN typically manifest as painful, fast growing masses. While the imaging features of malignant masses can be nonspecific, knowledge of the typical radiologic manifestations of MCWN may suggest a specific diagnosis. We review imaging features of the most common MCWN with images collected at an outpatient academic oncologic center. OBJECTIVE While the imaging features of patients with malignant masses can be nonspecific, knowledge of the typical radiologic manifestations of MCWN may suggest a specific diagnosis. We review distinguishing imaging features of the most common MCWN, including epithelial and mesenchymal malignancies, with images collected at an outpatient oncologic center. CONCLUSION Chest wall neoplasms encompass 5% of all thoracic tumors, with nearly half of chest wall neoplasms being malignant. Out of these malignant neoplasms, 50% are primary and the commonest one is chondrosarcoma. Although distinguishing imaging features may suggest a specific diagnosis in the majority of MCWN, most affected patients undergo biopsy for a definitive diagnosis.

Abstract
A 58-year-old female who presented with a lower gastrointestinal bleed was referred for an (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT after a colonoscopy revealed a submucosal mass in the ascending colon. The PET/CT confirmed the presence of an FDG-avid mass in the ascending colon with no other FDG-avid abnormalities. Dual time-point imaging was performed and showed a significant increase in FDG uptake in the mass, which raised strong suspicion of a colon malignancy. Although an initial biopsy of the mass did not show evidence of neoplasia, a decision was made to proceed with a right hemicolectomy based on high clinical and imaging suspicion of malignancy. Histological evaluation of the hemicolectomy revealed a benign colon desmoid tumour.

Abstract
OBJECTIVE Desmoid tumour is a common extraintestinal manifestation of patients with familial adenomatous polyposis (FAP) who have undergone prophylactic colectomy. We aimed to determine whether MRI provides equivalent or better assessment of desmoid tumours than CT, the current first-line investigation. METHODS Following ethics approval and informed consent, FAP patients with known desmoid tumour underwent contrast-enhanced 64-slice multidetector CT (MDCT) and 1.5 T MRI (incorporating T(1) weighted, T(2) weighted, short tau inversion-recovery and T(1) weighted with contrast, axial, sagittal and coronal sequences). The number, site, size, local extent, tumour signal intensity and desmoid-to-aorta enhancement ratio were analysed. RESULTS MRI identified 23 desmoid tumours in 9 patients: 9 intra-abdominal desmoid (IAD) tumours, 10 abdominal wall desmoid (AWD) tumours and 4 extra-abdominal desmoid (EAD) tumours. CT identified only 21 desmoids; 1 EAD and 1 AWD were not identified. The two modalities were equivalent in terms of defining local extent of desmoid. Five IAD tumours involved the bowel, six caused ureteric compression and none compromised the proximal superior mesenteric artery. There was no difference in median desmoid size: 56.7 cm(2) (range 2-215 cm(2)) on MDCT and 56.3 cm(2) (3-215 cm(2)) on MRI (p=0.985). The mean MRI enhancement ratio, at 1.12 (standard deviation 0.43), was greater than the CT enhancement ratio, which was 0.48 (0.16) (p<0.0001). High signal intensity on T(2) MRI was associated with increased MRI enhancement ratio (p=0.006). CONCLUSIONS MRI is at least equivalent (and may be superior) to MDCT for the detection of desmoid tumours in FAP. Coupled with the advantage of avoiding radiation, it should be considered as the primary imaging modality for young FAP patients.
