Isolated splenic Mycobacterium tuberculosis complex infection in an immunocompetent individual with FDG-PET positive mass

Solitary Splenic Metastasis From Endometrial Carcinoma Revealed on FDG PET/CT

ABSTRACT

Solitary splenic metastasis from endometrial carcinoma is rare. We report a case of imaging findings of solitary splenic metastasis in a 53-year-old woman who underwent resection surgery of endometrial carcinoma of uterus 1 year ago. On FDG PET/CT, it presented as a solitary soft tissue mass with an SUVmax of 18.44. The postoperative pathology supported metastasis from endometrial carcinoma.

Pyo pneumothorax revealing splenic tuberculosis abscess in a COVID-19 femmal: A case report

•

In areas where tuberculosis is prevalent, a splenic tuberculosis should be considered in the differential diagnosis of patients presenting with fever of unknown origin and splenomegaly.

•

The diagnosis can be made later when complications occur as well as spontaneous rupture of the spleen.

•

Although rare, chest rupture can occur and symptoms can be respiratory as well as pyopneumothorax or empyema, which can lead to inaccurate diagnosis and inappropriate treatment of the an underlying condition.

Contrast-Enhanced Ultrasound Imaging Features of Focal Splenic Tuberculosis

Background

The aim of this study was to characterize the contrast-enhanced ultrasound imaging features of focal splenic tuberculosis.

Material/Methods

We retrospectively analyzed the conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) imaging features of 22 patients with splenic TB confirmed by surgical histopathology or biopsy.

Results

Conventional US demonstrated that 15 of the 22 patients had a single lesion, while 7 had multiple lesions. The maximum diameter of the lesions ranged from 1.0 to 3.7 cm. Of the 22, 17 were detected with hypoecho and 5 were detected with complex echo by conventional US. Seven (7/22) were detected with blood flow signals by color Doppler flow image (CDFI). CUES demonstrated that 18 cases (81.8%, 18/22) began to enhance in the arterial phase, mostly followed by slow wash-out in the intermediate or late parenchymal phase, and 4 (18.2%, 4/22) presented with non-enhancement during all phases. The enhancement patterns were categorized into 4 types: Type I, homogeneous enhancement (2/22); Type II, rim-like enhancement (12/22); Type III, septation-like enhancement (4/22); and Type IV, non-enhancement (4/22).

Conclusions

CEUS showed that splenic TB lesions were enhanced in the arterial phase, followed by slow washed out or persistent enhancement in the intermediate and late parenchymal phases. The rim- or septation-like enhancement may be helpful for diagnosing splenic TB. The splenic lesions presenting round hypoecho by conventional US and complete non-enhancement by CEUS are highly suspicious of splenic TB.
