Imaging findings of inflammatory myofibroblastic tumor from the greater omentum: One case report

Inflammatory myofibroblastic tumor: A rare cause of intestinal obstruction: Case report

INTRODUCTION AND IMPORTANCE

Inflammatory myofibroblastic tumor IMT1 is a rare neoplasm with diverse clinical presentations, needing histological confirmation for diagnosis. The tumor often mimics malignant conditions, making accurate diagnosis challenging.

CASE PRESENTATION

We report a case of a 29-year-old male presenting with long standing recurrent abdominal pain, with more recent increasing frequency and associated weight loss. Imaging revealed a heterogenous soft tissue lesions causing mechanical small bowel obstruction, prompting surgical intervention. Histology analysis confirmed the diagnosis of IMT.

CLINICAL DISCUSSION

This case highlights the importance of considering IMT in the differential diagnosis of neoplastic mechanical small bowel obstruction, particularly in patients presenting with atypical symptoms and image findings. Despite its rarity, IMT should be considered, as it can present similarly to more common malignancies. Further research is warranted to unravel the pathogenesis and refine management strategies for this intriguing neoplasm.

CONCLUSION

IMT is a rare and intriguing neoplasm that presents significant diagnostic challenge. This case emphasize the need for thorough histological evaluation to confirm rhe diagnosis and guide appropriate management strategies.

Inflammatory Pseudotumor of the Omentum in Contrast-enhanced Ultrasound

Aim of the study

Inflammatory pseudotumor is a rare benign tumor that can occur at various body sites. Due to its rare occurrence and histological variety radiological data is heterogeneous and limited.

Case description

We present a case of a 71-year-old man with inflammatory pseudotumor of the omentum. Contrast-enhanced ultrasound perfusion pattern showed homogeneous, isoechoic enhancement in the arterial phase with a washout phenomenon in the parenchymal phase, mimicking a peritoneal carcinomatosis.

Conclusions

Inflammatory pseudotumor represents a rare, but important benign differential diagnostic option when considering a malignant disorder. Contrast-enhanced ultrasound is helpful in identifying vital tissue for a targeted biopsy for subsequent histological examination that is essential for the exclusion of malignancy.

Rare presentation of inflammatory pseudotumour involving subcutaneous tissues with superficial fat sparing

We present a unique case of inflammatory pseudotumour involving gluteal subcutaneous tissue with the sparing of superficial fat and report its contrast-enhanced CT, F-18 fluorodeoxyglucose positron emission tomography/CT and pathological findings. Although rare, inflammatory pseudotumours have been reported with a diverse spectrum of locations; however, the involvement of the subcutaneous tissue overlying the gluteal muscles with sparing of the most superficial fat has not been reported.
