Imaging Pitfalls

The authors present a case report of an atypical liver vascular malformation in a cat. The lesion was diagnosed first by ultrasound, fine needle aspiration and computed tomographic examination, which revealed the presence of a thin-walled single echogenic oval structure in the caudate lobe of the liver without visible flow in Doppler examination and with content similar to blood. The echogenicity of the lesion was variable, which depended on its size and time after aspiration. Initially, atypical haemangioma was suspected. After surgical removal, histopathological examinations were performed. The final diagnosis was a benign angioproliferative lesion.

BACKGROUND: Lipomas are benign formations with the mesenchymal origin, which are found in the head and neck region in a very small percentage of cases. In these cases, they usually occur in the posterior neck and usually grow very slowly without causing complaints. However, when they cover the front of the neck, it is necessary to confirm the adipose origin of a tumour and to exclude the connection with the thyroid gland. Although in principle, lipomas are benign, there are three more unfavourable possibilities of 1) malignancy of lipomas, 2) the occurrence of de novo liposarcomas or 3) the association of lipomas with other tumours, such as retinoblastoma. CASE REPORT: We present a 74-year-old woman with a painless subcutaneous formation in the neck. A Fine Needle Aspiration Biopsy (FNA) was performed, with the conclusion of the cytological result for lipoma. Surgical removal was planned under general anaesthesia. CONCLUSION: Usually, lipomas do not require surgery, but when they engage muscles they become indicative of surgical treatment.

Abstract Introduction/Objective Malakoplakia is a granulomatous disease of infectious etiology that affects immunosuppressed individuals. It commonly involves the genitourinary tract, but the involvement of other systems and organs has been reported. Gram-negative bacterial infections are mostly the responsible agent, with Escherichia coli found in approximately 80% of cases. Malakoplakia can present clinically and radiologically as a malignancy. Methods/Case Report We present a case of a 16-year-old male with a history of acute liver failure requiring liver transplantation due to autoimmune hepatitis. He was admitted with concerns for rejection, and he was found to have an abdominal wall mass. MRI studies showed a lobulated, solid, and cystic mass measuring 11.0 x 4.9 x 1.9 cm in the right abdominal wall. The mass was extending through all the layers of the abdominal wall and protruding into the abdominal cavity with mass effect on the liver, encasing the common bile duct, hepatic artery and main portal vein, concerning for malignancy, versus a possible infectious process. Ultrasound-guided FNA and biopsy were performed. The Diff-Quik and Papanicolaou-stained smears showed abundant foamy macrophages with numerous granular intra- and extracellular slightly refractile inclusions (4-10 um), rare multinucleated giant cells, and fibroblasts. A Von Kossa stain highlighted the targetoid inclusions consistent with Michaelis-Gutman bodies. Additional stains were performed on the core needle biopsy, and the histiocytes were positive for CD68 and CD163. Stains for keratins, CD45, HSA, CD1A, and Langerin were negative. No acid-fast or fungal microorganisms were identified on AFB and GMS stains, respectively. The final diagnosis was malakoplakia, with no evidence of malignancy. Results (if a Case Study enter NA) NA Conclusion Fine-needle aspiration cytology is useful in establishing a fast diagnosis of malakoplakia and excluding malignancies.

Cytological Evaluation

Objective To evaluate the efficacy of rapid on-site cytological evaluation (ROSE) in determining specimen adequacy and diagnostic accuracy in the interventional diagnosis of lung lesions. Methods This retrospective study included 127 consecutive cases of lung lesions, which were sampled by bronchoscopy or transthoracic fine needle aspiration, and diagnosed on ROSE followed by histopathology. ROSE was performed by a trained pulmonologist and the diagnosis of ROSE was compared with the final diagnosis. Results The sensitivity of ROSE in determining adequacy of specimens was 97.5% and specificity in determining inadequacy was 85.7%. The diagnostic efficacy of ROSE for assessing malignancy (sensitivity of 94.5% and specificity of 100%) and non-malignancy (sensitivity of 97.8% and specificity of 100%) was excellent. The sensitivity of ROSE for diagnosing small cell carcinoma (100%) was highest, followed by adenocarcinoma (89.2%) and squamous cell carcinoma (75.0%). Performance of ROSE by a trained pulmonologist also determined tuberculosis with a high diagnostic sensitivity (83.3%) and specificity (100%). Conclusions A trained pulmonologist can reliably carry out ROSE to ensure the adequacy of the sample, distinguish between malignancy and non-malignancy, and make a preliminary diagnosis in a large number of cases.
