We describe a new light transport model, which was applied to three-dimensional lifetime imaging of Förster resonance energy transfer in mice in vivo. The model is an approximation to the radiative transfer equation and combines light diffusion and ray optics. This approximation is well adopted to wide-field time-gated intensity-based data acquisition. Reconstructed image data are presented and compared with results obtained by using the telegraph equation approximation. The new approach provides improved recovery of absorption and scattering parameters while returning similar values for the fluorescence parameters.

This case report describes a 66-year-old male diagnosed with a giant retroperitoneal lymphangioma, presenting with an abdominal mass confirmed via magnetic resonance imaging (MRI). Laparoscopic surgery was successfully performed to excise the mass, with histopathological examination confirming the diagnosis. The patient's postoperative recovery was uneventful, with no signs of recurrence or metastasis observed at the three-month follow-up.

Background: Supratentorial function-eloquent brain tumour surgeries challenge the balance between maximal tumour resection and preservation of neurological function. This study aims to evaluate the efficacy of preoperative and intraoperative mapping techniques on resection outcomes and post-operative deficits.
Methods: This systematic review and meta-analysis examined literature up to March 2023, sourced from PubMed, Embase, and Medline.

Background: Extramedullary plasmacytoma (EMP) represents one of the rarer forms of plasma cell malignancies, capable of impacting a variety of tissues and organs throughout the body. The majority of EMP cases are predominantly found in the head and neck region, especially within the laryngopharynx, as well as in the gastrointestinal tract. While there have been documented instances of oropharyngeal involvement in EMP cases in the academic literature, it is important to note that EMP specifically affecting the uvula is exceedingly uncommon.

Background: Blue rubber bleb nevus syndrome (BRBNS) is a rare venous malformation disorder. Currently, there is no standard therapy for this disease. However, lauromacrogol, a sclerosant extensively utilized in the management of vascular malformations, has been applied in the treatment of BRBNS.
