To better characterize the frequency of Bosniak cyst class changes and identify predictors of change and progression. what bosniak stage is a complex renal cyst with septation and apparent mural nodule. cyst was 3 cm 7 years ago. now 5 x 4.9cm. urology consult soon.
Of the 19 removed lesions, 16 (84%) were malignant, and 3 (16%) were benign (one inflammatory cyst including a nephrolith, one cystic nephroma and one atypical angiomyolipoma). CT and histological findings of 19 Bosniak III cysts were correlated. Mean lesion size was 4.6 cm (range, 1.1–8.1 cm) for Bosniak category III lesions and 3.5 cm (range, 1.2–22.0 cm) for Bosniak category IV lesions. The mean size of malignant lesions was 4.1 cm, and that for benign lesions was 3.4 cm, with no significant statistical difference noted ( p = 0.387). Bosniak 3 • indeterminate o thick, nodular multiple septa or wall with measurable enhancement, hyperdense on CT (see 2F) o treatment/work-up: partial nephrectomy or radiofrequency ablation in elderly or poor surgical candidates o percentage malignant: ~55% 6 Bosniak 4 • clearly malignant o solid mass with a large cystic or a necrotic component o treatment: partial or total nephrectomy 2019-09-07 Bosniak III and IV category renal cysts have measurable enhancement in thickened walls or septa on CT or MRI studies, and the presence of well-defined nodular soft-tissue components differentiates Bosniak IV from III renal cysts [1–3].
Bosniak IIF lesions vary in appearance: (1) BIIF lesions with minimal findings close to category II in complexity and (2) BIIF lesions that are closer to category III in complexity. M.A. Bosniak has recently suggested that BIIF cysts with minimal findings only need follow-up for 1–2-years, whereas more complex BIIF cysts should be followed for a longer period (e.g., 3–4 years or longer) [ 1 ].

The mean largest diameter was 48.7 ± 28.8 mm. All lesions were multilobulated and septated. Of the 19 removed lesions, 16 (84%) were malignant, and 3 (16%) were benign (one inflammatory cyst including a nephrolith, one cystic nephroma and one atypical angiomyolipoma).

2012; 262:152-60. [ Links ] some small renal masses are cystic in nature. the bosniak classification is used to classify these lesions, approximate risk of malignancy and direct management.13 Table 3 lists the bosniak classification and Table 4 outlines the basic management and follow up plan for patients in each of the bosniak classifications. o Of the Bosniak IIF lesions – after median follow up of 15 months (range 3-98) 12 cases (14.8%) progressed in radiological complexity with a median time to progression of 11 months (3-98 The Bosniak renal cyst classification was introduced in 1986. This classification was based on computed tomography (CT).
No patient in this study developed metastatic disease within the three-year followup period.

Bosniak staging governs the decision to operate on CRCs [2, 3]. This classification of renal cystic lesions was produced in an attempt to standardize the evaluation of the condition across all imaging modalities. Association with Bosniak category was explored. 121 patients (84:37 M:F) were identified with 136 renal lesions (84, 37 and 15 Bosniak category 2F, 3 and 4) and followed for 1–12.3 years (mean 3.5 years).

It was last updated in 2005 12 . A Bosniak classification, version 2019 11 has been proposed to increase the accuracy and include MRI features but does not yet (c. 2021) have widespread validation. However, in the 8 benign lesions, there were 4 category inconsistent lesions (classified as Bosniak category IIF on CT but upgraded to Bosniak III on MR). Pathologically, they were all benign multi-locular cysts, including 1 with inflammatory granulation and hematoma, another accompanied by hemorrhage. Approximately half of resected Bosniak III masses are malignant, with rates in individual series ranging from 25% to 100% (12, 34, 35, 62). The converse is that approximately half of all resected Bosniak III masses are benign, resulting in potential harms of surgery with no clinical benefit. Posts: 7.
